How it is made

From butyl oleate by a Boweault-Blanc reduction with sodium and butyl alcohol, or from triolein by hydrogenation in the presence of zinc chromate. Purification by fractional crystallization at -40 °C from acetone, followed by distillation.

Prepared by catalytic hydrogenation under pressure of the methyl esters of unsaturated fatty acids, mixed catalysts containing zinc are employed, and the reaction conditions correspond to those for the production of saturated fatty alcohols.
