Abstract
Phenolic antioxidants such as 1,1-dimethyl-2-(3,5-di tert.butyl-4-hydroxyphenyl) ethyl amine and a method of preparing said antioxidants involving the reaction between a 3,5-di tert.alkyl-4-hydroxybenzyl halide; N,N-dialkyl amine or dithiocarbamate such as 3,5-di tert.butyl-4-hydroxybenzyl chloride; 2,6-di tert.butyl-4-dimethylaminomethylphenol or 3,5-di tert.butyl-4-hydroxybenzyl N,N-dimethyldithiocarbamate and a nitroalkane such as 2-nitropropane to produce a nitro compound such as 1,1-dimethyl-2-(3,5-di tert.butyl-4-hydroxyphenyl)-1-nitroethane which can be catalytically reduced to form the aminoalkyl phenol.
