Sulfur containing derivatives of dialkyl-4-hydroxyphenyltriazine

Abstract

Novel sulfur derivatives of dialkyl-4-hydroxyphenyltriazine were prepared which are stabilizers of organic material. Certain of these compounds can be prepared (1) by direct alkylation of 2,6-dialkylphenol with a 2,4-bis(alkylthio)-6-chloro-1,3,5-triazine compound; (2) by the reaction of an alkyl mercaptan with the appropriate 6(3',5'-dialkyl-4'-hydroxyphenyl)2,4-dichloro-1,3,5-triazine; or (3) by the reaction of an acid chloride of dialkylhydroxybenzoic acid with a mono or dialkyl substituted dithiobiuret. A typical embodiment of this invention is 6(3',5'-di-t-butyl-4'-hydroxyphenyl)-2,4-bis(n-octylthio)-1,3,5-triazine. The compounds of this invention are useful as stabilizers of organic materials which are subject to oxidative and thermal deterioration.
