4 Claims. (Cl. 25248.6)
This invention relates to new and improved corrosion inhibiting compositions having excellent lubricating properties.
A serious problem in the field of lubrication and hydraulic systems exists where normally effective corrosion inhibiting lubricants or hydraulic fluids cannot continuously come in contact with parts of equipment they are supposed to lubricate and protect. Thus, during idle periods or on storage not all partsare protected by the contacting lubricant and these parts become susceptible to rust and corrosion. This problem becomes particularly grave where corrosive gases, moisture, high temperatures and other corrosion producing factors are present or form as in steam turbine lubricants, turbine oils, and various equipment such as hydrauli equipment, which comes in contact with moisture and the like.
It has now been discovered that the above objects can be attained by addition to various lubricating oil compositions, such as turbine oils and the like, a minor amount of a particular type-of vapor phase corrosion inhibiting agent selected from low molecular weight aliphatic monocarboxylicacids containing from 8.to carbon atoms in the molecule. The acids can .bestraightchain, branched, saturated or unsaturated, aliphatic monocarboxylic acids of which the C3 to C10 straightchain aliphatic monocarboxylic acids are preferred. Included, however, among these acids are the saturated aliphatic monocarboxylic ac1ds such as the straight-chain, octanoic, nonanoic, decanoic, acids; branched chain aliphatic acids such as isononanoic acid and 3,5,5-trimethyl hexanoic acid and the like. Of the acids, the straightchain aliphatic monocarboxylic acids are preferred, namely, the n-octanoic, n-nonanoic andn-decanoic acids.
The manner in which these acids function as vapor phase corrosion inhibitors particularly at ambient temperatures in systems of this invention is not clearly understood. However, these acids have been foundto function as efiiective vapor phase corrosion inhibitors from oil solutions thereof.
These vapor phase corrosion inhibiting acids are effective when added torvarious types of lubricating oils but are particularly useful in compounded lubricating oils containing as active agents one or more of the following class of compounds (a) oil-soluble sulfur-containing compounds such as sulfurized oils and derivatives thereof such as sulfurized fatty oils and sulfurized fatty acids, examplified by sulfurized sperm or whale oils and sulfurized oleic, linoleic and dimerized 'linoleic acids; (b) oil-soluble phenolic compounds such as alkylated phenols which are illustrated by 2,6-ditertiarybutyl-4-methyl phenol, 2,4,6 -.trimethylphenol, 2,4.-.dimethyl-6-tertiarybutyl phenol; 2,2'-methylene bis(4-methyl-6-tertiarybutyl phenol); (c) oil-soluble aliphatic polycarboxylic acids and/or amides or partial esters of said acids such as monoor polyalkylor alkenylapolycarboxylic acids, wherein the alkyl or alkenyl group or groups. contain from 3 to 36 and preferably from 8 to 18 carbon atoms. Such acids include oil-soluble C6 to C36 and preferably C8 to C18 alkylor alkenyl-malonic, succinic, glutaric, adipic, pimelic, sebac-ic, azelaic, tartaric, citric, ma-leic, citraconic acids, of which the preferred acids are C16- alkenylsuccinic acid, Cra-alkeny-lsuccinic acid, Cas-alkenylsuccinic acid, and corresponding alkylsuccinic acids, Cm-Cm-alkyltartaric acid, Cin-Cia-alkylmalonic acid. Partial or full amides and/or the partial esters of these acids can be used, and include alkylsuccinic acid monoamide or monoo'leyl alkenylsuccinate, monooctyl alkylsebacate, monobutyl alkyltartrate, monoisopropyl citrate, mono 2-ethylhexyl citrate, ester of wax phenol and alkenylsuccinic acid, ethyl decanylsuccinate, decyl isobutenylsuccinate, alkenylsuccinic acid mono (-dicyclohexyl)amide, Cm-alkenylsuccinic acid mono (Z-ethylhexyl)amide, C1sa1kenylsuccinic acid monoamide; alkenylthiosuccinic acid, alkenylthiotartaric acid, 2-(1- thiotridecyl)succinic acid, 2-(1-thiodecy'l')'tartaric acid, 2-. (l-thioarnyl) citric acid, octadecylsuccinic acid, etc., and mixtures thereof;
The vapor phase corrosion inhibitors of this invention are activated by the class of compounds and mixtures thereof as enumerated in classes a, b and c. The manner in which this is accomplished is not understood but nevertheless a synergistic efiect is produced when (a), (b) and/ or (c) are used in combination with the vapor phase inhibitors of this invention. "By means of this invention metal parts which are not in direct contact with the lubricant are equally protected against rust and corrosion.
Inaddition to the above-mentioned class of compounds other useful agents can be used in lubricants to which the vapor phase corrosion inhibitor is added. Included can be aromatic acids such as benzoic, salicylic, mandelic and cinnamic acids; oiliness agents, extreme pressure agents, anti-clogging agents and the like.
The base for additives of this invention can be a hydrocarbon oil obtained from a parafiinic, naphthenic, Mid-continent or Coastal stock and/0r mixtures thereof and preferably base stocks which have been highly refined. The viscosity of these oils may vary over a wide range such as from 50 SUS at F. to 100 SUS at 210 F.
The vapor phase corrosion inhibitors, namely, the C3 to C10 aliphatic monocarboxylic acids as well as any additional agents which can be present can each be used in amounts of from 0.001% to about 5% and preferably from 0.01% to 1% depending upon the base oil and additive present in said base oil.
