Abstract: HYDROCARBYL - HYDROXYVPHENYL - DIHYDROCARBYLDITHIOCARBAMATES AE PREPARED BY THE REACTION OF DIHYDROCARBYL HALOPHENOLS WITH A METAL SALT OF A DIHYDROCARBYLTHIOCARBAMATE. FOR EXAMPLE, THE REACTION OF 2,6-DI-TERT-BUTYL-4BROMOPHENOL WITH THE SODIUM ALST OF DIMETHYLDITHIOCARBAMATE YIELDS 3,5-DI-TERT-BUTYL-4-HYDROXYPHENYL DIMETHYL DITHIOCARBAMATE. THE COMPOUNDS ARE USEFUL AS ANTIOXIDANTS. EFFECTIVENESS IS ENHANCED BY DIHYDROCARBYL THIODIALKANOATES AND ORGANIC PHOSPHITES OR PHOSPHONATES.

Abstract: Organic material, especially polypropylene, is stabilized by the addition of mono- or di- (dihydrocarbyl-hydroxyphenyl) alkyl phosphates, phosphites, thiophosphates or thiophosphites, such as 3,5-di-tert-butyl-4-hydroxyphenyl di-n-octadecyl phosphate. Effectiveness is synergistically improved by inclusion of a dialkyl thiodialkanoate such as dilaurylthiodipropionate.
