AUTOSYNERGISTIC PHENOLIC ANTIOXIDANT REACTION PRODUCT

摘要

AUTOSYNERGISTIC PHENOLIC ANTIOXIDANT REACTION PRODUCT This invention is concerned with the stabilization of oxidizable organic materials such as rubbers, oils, plastics and the like through the addition of an autosynergistic phenolic antioxidant reaction product to the oxidizable organic material. More specifically, this invention is directed to a definitive process for the preparation of an alkylated phenol/formaldehyde/ mercaptan reaction product comprising the simultaneous acid catalyzed reaction of specific reactants at specific molar ratios under azeotroping conditions and the use of the reaction product in oxidizable organic materials.
