Definitions
- additives are used to improve the oxidation stability, anti-wear and extreme pressure characteristics, pour point, viscosity index, etc. of lubricants, as well as to improve the combustion properties, rust-resistance, oxidation stability and other properties of petroleum-derived fuels.
- these additives in their active state are admixed with the particular composition sometime prior to the time of ultimate use. This is often a significant disadvantage since it means that the additive may precipitate out or may be subject to degradation and deterioration prior to the complete use of the fuel or lubricant composition. As a result the effectiveness of the additive is frequently lessened or eliminated during the period when it is most needed. It would therefore be desirable to provide a means whereby the effectiveness of the additives could be regulated and controlled.
- the above mentioned disadvantages are largely overcome by employing the fuel or lubricant additives in the form of certain types of inclusion compounds wherein the additive is contained within the frame work of another compound.
- inclusion compounds of the present invention are formed by combining the chemical additive, e.g., antioxidant, E.P. agent, combustion improver etc. which is herein referred to as the guest compound with a selected compound, i.e., the host, which because of its stereochemical properties and/ or polarity, has the ability to spatially enclose the guest compound.
- the additives of the present invention may be in the form of either of two general types of inclusion compounds which are classified according to the nature of the host or enclosing compound. These inclusion compounds are either (1) polymolecular or lattice inclusion compounds or (2) monomolecular inclusion compounds.
- the polynuclear or lattice inclusion type are inclusion compounds composed of polymolecular host structures where the lattice is built up from smaller single molecules.
- the host structure of such compounds may contain either channel-like spaces or cages (clathrates).
- Some examples of inclusion compounds of this type are those wherein the host compound is urea, thiourea, chloeic acids, i.e., desoxycholic and apochlolic acid, hydroquinone, phenol, triortho-thymotides etc.
- the monomolecular inclusion compounds are so termed because it is thought that only one molecule is host to the guest molecule.
- the host compound will therefore be large and will generally possess spaces in its center as in the case of larger ring molecules.
- the cyclodex- 3,314,834. Patented Apr. 18, 1967 trins of either the 0:, B or 'y type are typical monomolecular host compounds.
- the inclusion compounds of the invention are, as far as is known, addition compounds wherein the guest compound, i.e., chemical additive, is geometrically entrapped within the cavities of the host.
- the selection of particular guest compounds is limited by geometrical rather than chemical considerations.
- any additive compound possessing a molecular geometry, i.e., a size and shape, which both allows entrance into the available space of the host compound and prevents ready escape through the openings in the framework of the host may be formed into an inclusion compound and employed according to the present invention.
- Suitable additives which may be used as guest compounds include fatty acids, such as those containing 1 to about 18 carbons; carboxylic acid esters including aliphatic, aromatic or mixed esters; ketones such as acetone, methyl ethyl ketone etc.; ethers; long chain or fatty alcohols; phenols; halogenated organic compounds including halogenated paraffins, halogenated carboxylic acids; organic sulfur compounds; primary, secondary and tertiary amines etc.
- fatty acids such as those containing 1 to about 18 carbons
- carboxylic acid esters including aliphatic, aromatic or mixed esters
- ketones such as acetone, methyl ethyl ketone etc.
- ethers long chain or fatty alcohols
- phenols halogenated organic compounds including halogenated paraffins, halogenated carboxylic acids
- organic sulfur compounds primary, secondary and tertiary amines etc.
- gaseous materials such as hydrogen chloride, ammonia, chlorine, bromine and sulfur dioxide, which because of their physical state have not been especially useful as additives, maybe used as additives in the form of inclusion compounds.
- Phenol, hydroquinone and the cyclodextrins are particularly suitable as host compounds with these gases.
- the procedure for preparing the inclusion compounds will vary depending on a number of factors especially the nature of the host and guest compounds.
- a convenient method is use of a mutual solvent to bring the two components together, or in the case of gaseous additives the guest compound may be bubbled through a suitable solution, dispersion etc. of the host compound.
- the inclusion of the invention may be prepared. in situ, i.e., while present in the fuel or lubricant compositions.
- the preparation of inclusion compounds used according to the present invention is well known in the art. Particular details regarding these compounds and their preparation are described in Clathrate Inclusion Compound, M. Hagan, Reinhold Publishing Company, 1962, and in "Eintician für, F. Cramer, Springer Verlag, Berlin, 1954.
- the guest and host compounds are normally not chemically bonded together, they can be readily freed from the inclusion structure and made available for chemical reaction. In general, any mechanism which destroys the framework of inclusion compound or supplies sufficient energy will set free the included additive. Thus, in order to free the guest from the structure it is only necessary to melt, dissolve or otherwise disintegrate the structure of the host compound. It should be noted, however, that since the guest molecule is completely enclosed by the host compound, the guest or chemical additive, is substantially prevented from reacting with the particular environment around the inclusion compound until the additive is released from the surrounding host compound.

Description
United States Patent 3,314,884 FUELS AND LUBRICANTS CONTAINING INCLUSION COMPOUNDS Richard E. Cover, Woodhaven, N.Y., assignor to Mobil Oil Corporation, a corporation of New York No Drawing. Filed Jan. 2, 1964, Ser. No. 335,422 20 Claims. (Cl. 252) The present invention relates to organic compositions such as lubricants and fuels and to an improved type of additive for these compositions.
As is known in the art, a variety of chemical compounds are normally added to fuels and to lubricating compositions in order to improve their characteristics in various respects. Thus, for example, additives are used to improve the oxidation stability, anti-wear and extreme pressure characteristics, pour point, viscosity index, etc. of lubricants, as well as to improve the combustion properties, rust-resistance, oxidation stability and other properties of petroleum-derived fuels. Normally, these additives in their active state are admixed with the particular composition sometime prior to the time of ultimate use. This is often a significant disadvantage since it means that the additive may precipitate out or may be subject to degradation and deterioration prior to the complete use of the fuel or lubricant composition. As a result the effectiveness of the additive is frequently lessened or eliminated during the period when it is most needed. It would therefore be desirable to provide a means whereby the effectiveness of the additives could be regulated and controlled.
In accordance with the present invention, the above mentioned disadvantages are largely overcome by employing the fuel or lubricant additives in the form of certain types of inclusion compounds wherein the additive is contained within the frame work of another compound.
It is therefore an object of the present invention to provide improved fuel and lubricating compositions possessing a superior type of chemical additive. A further object is to provide improved additives for fuel and lubricant compositions. Another object is to furnish a means for controlling additive release in such compositions. Further objects of the invention and the advantages thereof will become apparent hereinafter.
In general, inclusion compounds of the present invention are formed by combining the chemical additive, e.g., antioxidant, E.P. agent, combustion improver etc. which is herein referred to as the guest compound with a selected compound, i.e., the host, which because of its stereochemical properties and/ or polarity, has the ability to spatially enclose the guest compound. More particularly, the additives of the present invention may be in the form of either of two general types of inclusion compounds which are classified according to the nature of the host or enclosing compound. These inclusion compounds are either (1) polymolecular or lattice inclusion compounds or (2) monomolecular inclusion compounds.
The polynuclear or lattice inclusion type are inclusion compounds composed of polymolecular host structures where the lattice is built up from smaller single molecules. The host structure of such compounds may contain either channel-like spaces or cages (clathrates). Some examples of inclusion compounds of this type are those wherein the host compound is urea, thiourea, chloeic acids, i.e., desoxycholic and apochlolic acid, hydroquinone, phenol, triortho-thymotides etc.
The monomolecular inclusion compounds are so termed because it is thought that only one molecule is host to the guest molecule. The host compound will therefore be large and will generally possess spaces in its center as in the case of larger ring molecules. The cyclodex- 3,314,834. Patented Apr. 18, 1967 trins of either the 0:, B or 'y type are typical monomolecular host compounds.
The inclusion compounds of the invention are, as far as is known, addition compounds wherein the guest compound, i.e., chemical additive, is geometrically entrapped within the cavities of the host. Thus, the selection of particular guest compounds is limited by geometrical rather than chemical considerations. In general, any additive compound possessing a molecular geometry, i.e., a size and shape, which both allows entrance into the available space of the host compound and prevents ready escape through the openings in the framework of the host, may be formed into an inclusion compound and employed according to the present invention. Some examples of suitable additives which may be used as guest compounds include fatty acids, such as those containing 1 to about 18 carbons; carboxylic acid esters including aliphatic, aromatic or mixed esters; ketones such as acetone, methyl ethyl ketone etc.; ethers; long chain or fatty alcohols; phenols; halogenated organic compounds including halogenated paraffins, halogenated carboxylic acids; organic sulfur compounds; primary, secondary and tertiary amines etc.
According to a particular aspect of the invention, it has been found that gaseous materials such as hydrogen chloride, ammonia, chlorine, bromine and sulfur dioxide, which because of their physical state have not been especially useful as additives, maybe used as additives in the form of inclusion compounds. Phenol, hydroquinone and the cyclodextrins are particularly suitable as host compounds with these gases.
The procedure for preparing the inclusion compounds will vary depending on a number of factors especially the nature of the host and guest compounds. A convenient method is use of a mutual solvent to bring the two components together, or in the case of gaseous additives the guest compound may be bubbled through a suitable solution, dispersion etc. of the host compound. Depending on the nature of the other ingredients present, the inclusion of the invention may be prepared. in situ, i.e., while present in the fuel or lubricant compositions. The preparation of inclusion compounds used according to the present invention is well known in the art. Particular details regarding these compounds and their preparation are described in Clathrate Inclusion Compound, M. Hagan, Reinhold Publishing Company, 1962, and in "Einschlussverbindungen, F. Cramer, Springer Verlag, Berlin, 1954.
Since the guest and host compounds are normally not chemically bonded together, they can be readily freed from the inclusion structure and made available for chemical reaction. In general, any mechanism which destroys the framework of inclusion compound or supplies sufficient energy will set free the included additive. Thus, in order to free the guest from the structure it is only necessary to melt, dissolve or otherwise disintegrate the structure of the host compound. It should be noted, however, that since the guest molecule is completely enclosed by the host compound, the guest or chemical additive, is substantially prevented from reacting with the particular environment around the inclusion compound until the additive is released from the surrounding host compound.
The use of the included additives of the present invention offers several distinct advantages over the practice of employing the additives in their active state. For example:
(l) The degradation of the additive during storage and prior to use is minimized.
(2) It is possible to incorporate additional amounts or reserve amounts of additives above the present levels without affecting the properties of the fuel or lubricating compositions since the reserve amounts of additives are present in the inclusion compound and not capable of substantial chemical reaction with other components.

Although the above embodiments are limited to certain inclusion compounds, it should be noted that these specific embodiments are merely exemplary and the present invention is not limited thereto.
The present invention encompasses the use in the form of inclusion compounds of any chemical additive normally used in conjunction with fuels or lubricants to improve the characteristics thereof including but not limited to combustion improvers, ignition control agents, deposit modifiers, oxidation inhibitors, metal deactivators, antiicing agents, anti-corrosion agents, sludge depressants, de tergents, pour depressants, VI improvers, defoaming agents, color stabilizers, odor maskants etc.
Depending on the size and shape of these guest additives any host compound selected from the two general types hereinabove described may be employed.
The compounds of the present invention wherein the additive is in the form of an inclusion compound may be employed with various types of lubricants and hydrocarbon fuels. Thus, lubricants comprising both petroleum and synthetic oils, e.g., synthetic hydrocarbon and synthetic ester, such as greases and oils used with internal combustion engines, turbine engines, machinery, including hydraulic fluids, gear oils etc. may be improved by the use of the inclusion compounds of the present invention. The hydrocarbon fuels include gasoline, diesel fuel, kerosine, industrial and home fuel oils, jet fuels etc.
The lubricant and fuel compositions of this invention may, of course, also contain effective quantities of other ingredients normally used in such compositions and designed to improve the characteristics of these compositions in other respects. For example it may be desirable to employ suitable dispersing agents of either the ionic or non-ionic type or other additives which are not employed in the form of inclusion compounds.
