Plasticiser alcohol and production improvement

摘要

Embodiments of the invention disclosed herein relate to a process for the production of a C₆-C₁₅ alcohol mixture comprising the steps of: hydroformylating an olefin mixture comprising a branched C₅-C₁₄ olefin to form a hydroformylation product comprising aldehydes and formate esters, whereby the hydroformylation product has a net cold sap number from 15 to 38 mg KOH/g, and converting the aldehydes and formate esters to alcohols in a hydrogenation step comprising at least one first hydrogenation reactor comprising a fixed bed of a heterogeneous sulphided bimetallic catalyst.
