Abstract

An isoalkoxydiphenylamine is made by heating a hydroxydiphenylamine with an alcoholic alkali hydroxide solution in the presence of a secondary alkyl halide. Suitable hydroxydiphenylamines are listed, the preferred amines being 4-hydroxydiphenylamine and 4,41-dihydroxydiphenylamine. The secondary alkyl halide is preferably a chloride but bromides, fluorides or iodides may also be used. Suitable examples are given. It is preferred to use sodium hydroxide but any alkali hydroxide may be used. Methyl alcohol is preferred but ethyl, n-propyl and n-butyl alcohols are also given. The process takes place generally at temperatures from 100 DEG to 140 DEG C., preferably 110-130 DEG C. Examples describe reaction of 4-hydrodiphenylamine and 4,41-dihydroxydiphenylamine with 2-chloropropane in methanolic or ethanolic NaOH. Comparative experiments illustrate the use of lower temperatures or aqueous instead of alcoholic alkali hydroxide solution. Specification 443,779 is referred to.
