PROCESSES FOR THE MANUFACTURE OF SECONDARY FATTY ALCOHOLS, INTERNAL OLEFINS AND INTERNAL OLEFIN SULFONATES

摘要

Process P¹ for the manufacture of a secondary fatty alcohol, said process P¹ comprising synthesizing an internal ketone K1 by a process P⁰ comprising the decarboxylative ketonization reaction of a fatty acid or the like in a liquid phase with a metal compound as catalyst in a reaction medium, wherein a ketone K² at liquid state, which is identical or similar to the internal ketone K¹, is introduced into the reaction medium, and subjecting the internal ketone K¹ to a hydrogenation reaction with hydrogen gas as hydrogenating agent to form the secondary fatty alcohol. Use of the secondary fatty alcohol manufactured by the process P¹ for the manufacture of an internal olefin or of an internal olefin sulfonate.
