    摘要： Polyol carboxyalkylthioalkanoesterphenol compounds useful in the stabilization of organic materials normally susceptible to oxidative degradation are prepared by reaction of an appropriate polythio, which is a selected tetra-(mercapto alkanoic acid) ester of pentaerythritol or a selected tri-(mercapto alkanoic acid) ester of a selected 1, 1, 1-trimethylolalkane, with an appropriate alkenyl compound, which is a selected 4-hydroxy-(mono- or di-alkyl)phenylalkylalkenoate. In a preferred embodiment, the compound is pentaerythritol tetrakis [3,5-di-tert-butyl-4-hydroxyphenyl-(3-propyl)oxycarbonylethylthiopropionate].

    摘要： (Hydrocarbylthio)phenols containing hydrocarbylthio groups in either or both of the meta positions, relative to the hydroxy group, on a phenolic ring are prepared by reacting phenolic compounds with an excess of hydrocarbyl disulfide in the presence of catalytic amounts of an aluminum phenoxide. Novel and useful (hydrocarbylthio)phenols containing hydrocarbylthio groups in either of both of the meta positions, relative to the hydroxy group, on a phenolic ring can be prepared by this process. (Hydrocarbylthio)phenols containing hydrocarbylthio groups in either of both of the meta positions, relative to the hydroxy group, on a phenolic ring are effective antioxidants for organic material normally susceptible to oxidative deterioration, such as mineral oil.
