Process for the preparation of high molecular weight aliphatic monocarboxylic acids by silicate contact and chromosulfuric acid oxidation of {60 -olefins

摘要

Aliphatic monocarboxylic acids having from 16 to 70 carbon atoms in the molecule and being color-stable to ammonia and amines are prepared by chromosulfuric acid oxidation of such industrial-grade gamma -olefin mixtures which, before the oxidation, have been subjected to a thermal treatment in the presence of catalytic amounts of a silicate having a lamellar structure. The cited carboxylic acids are suitable for the manufacture of waxy substances.
