| titleOfInvention | 0,0-Dialkyl-(3,5-dialkyl-4-hydroxybenzyl)dithiophosphate compositions and process for making same |
| abstract | Organic material such as styrene-butadiene rubber is stabilized against oxidative degradation by the addition of an antioxidant composition made by the process comprising (A) reacting from 1-10 moles of a monohydric alkanol containing from one to about 50 carbon atoms with a mole of P2S5 at a temperature of from about 75* to about 125* C. to form a dithiophosphate reaction mixture; (B) neutralizing said dithiophosphate reaction mixture with aqueous ammonia; and (C) adding from about 1 to 3 moles of a hydroxybenzyl chloride to the neutralized reaction mixture and reacting at a temperature of from about 50* to 150* C. The preferred hydroxybenzyl chloride is 3,5-di-tert-butyl-4hydroxybenzyl chloride, and the preferred alkanol is a mixture of monohydric aliphatic C20-50 alcohols. |
