Process for preparing bis-substituted phenolic amides in the presence of an alcohol as solvent

摘要

A bis(substituted hydroxyaryl)amide of formula (I), where R is 4-120 C hydrocarbyl, each R' is H or 1-28 C alkyl, A is 2-10 C alkylene and x = 1-5, is prepared by mixing a lactone of formula (II) with a polyamine of formula R'(NHA)xNHR' (III) and an alcohol (IV) and heating the mixture to 60-180[deg]C. (IV) is a 2-10 C saturated aliphatic alcohol or a polyether alcohol of formula R"(OA')yOH, where R" is 1-30C hydrocarbyl, A' is 2-8 C alkylene and y = 1-30.
