Abstract
Abstract Novel 4-(m,m'-di-t-butyl-p-hydroxyphenyl)-butyl-2 diamides of aliphatic, araliphatic, cycloaliphatic or aromatic dicarboxylic acids which are intermediates in the manufacture of dyes, pesticides and plastics auxiliaries, particularly stabilizers for polyolefins and polyamides. When molten, they form specific solvents for alkylphenols and are perfumes or form ingredients of perfume compositions having a fruity odor.
