Definitions
- suitable compaction pressures in the practice of this invention will fall within the range of 6,895 to 206,850 kPa (1000 to 30,000 psi), and preferably in the range of 34,475 to 172,375 kPa (5000 to 25,000 psi).
- Such compaction can be conducted using, for example, a rotary tableting press operated at conventional rotational speeds, e.g., about 20 rpm.
- Another method for accomplishing the compaction is by means of pressure extrusion through a die orifice, while concurrently shearing the extrudate to produce compacted shapes of the desired size.
- Such ancillary materials should of course be compatible with the halogenated hydantoin and not interfere in any material way with the performance characteristics of the halogenated hydantoin.
- the amount(s) of such ancillary materials used should of course be sufficient to serve the purpose for which it is, or they are, being used. At the same time, the amount used should not materially detract from the physical, mechanical, or performance properties of the formulated product.
- the halogenated hydantoins can be compacted with or without use of a binder. In the practice of this invention it is preferred to conduct the compaction in the absence of a binder.
- Commonly-owned co-pending Application No. 09/487,816, filed January 18, 2000 relates in part to the compaction of the halogenated hydantoins using novel binders described therein.
- DCDMH is l,3-dichloro-5,5-d ⁇ methylhydantoin
- BCDMH is N,N'-bromochloro-5,5-d ⁇ methylhydantoin
- DBDMH is l ,3-dibromo-5,5- dimethylhydantoin.
- Example 1 The commerically available l,3-dihalo-5,5-dimethylhydantoins referred to in Example 1 were subjected to tableting operations.
- Five-gram samples of l,3-dibromo-5,5-dimethylhydantoin and four-gram samples of DCDMH and BCDMH were compacted without binder in a Sintech ® press (MTS Systems Corporation, Edenprairie, Minnesota) equipped with a punch and die fabricated from Hastelloy ® C alloy.
- the interior surfaces of the die were lightly dusted with micronized polypropylene wax (MICROPRO 400 wax; Micro Powders, Incorporated, Tarrytown, NY).
- the apparatus includes a horizontal circular-shaped load cell interfaced with a computer, a digital micrometer also interfaced with the computer, and a vertical screw-driven piston that is disposed above the load cell and adapted to apply a downward force perpendicular to the load cell.
- the procedure for measuring crush strength involves measuring the thickness of the tablet with the micrometer to provide a digitized input to the computer.
- the tablet is placed on its edge on the load cell with the piston in contact with the upper edge of the tablet.
- the apparatus is activated whereby the piston commences applying a progressively increasing downward diametral force to the tablet.
- the load cell continuously measures the downward force being applied to the tablet, and the input of such measurements is transmitted to the computer.
- pressure-compactible means that the substance in particulate form, and without prior treatment to enhance its compactibilit ⁇ . can be converted into a shape-retentive article by application of pressure to the substance when confined in a die.
- the term "pressure-compactible" when applied to a powder or finely-divided material used in forming a tablet, the term means that a shape-retentive tablet is formed when the powder or finely- divided material is subjected to the following conditions 1) A 1.80 cm- (0.71-inch) dianeter circular die fabricated from Hastelloy ® C alloy is lightly dusted with micronized polypropylene wax (MICROPRO 400 wax; Micro Powders, Incorporated, Tarrytown NY, or equivalent if MICROPRO 400 wax is not available).
- MICROPRO 400 wax micronized polypropylene wax
