hydrogenation of fatty ester to fatty alcohol treatment

Synthesising unsaturated fatty alcohols from fatty methyl

Unsaturated fatty alcohols are unique because they can only be obtained from natural raw materials Industrial production is currently based on high-pressure hydrogenation (260-300C and 25 -30 MPa) of methyl esters and fatty acids obtained respectively by transesterification and hydrolysis of oil (Kreutzer 1984 Voest 1984) These

Hydrogenation of Fatty Acid Methyl Esters to Fatty

ABSTRACT: Extremely rapid hydrogenation of fatty acid methyl esters (FAME) to fatty alcohols (FOH) occurs when the reaction is conducted in a substantially homogeneous supercritical phase using propane as a solvent over a solid catalyst At these conditions the limitations of hydrogen transport are eliminated At temperatures above 240C complete
