Title
Esterification of fatty acids with glycerol over Fe–Zn double-metal cyanide catalyst
Abstract

Solid Fe–Zn double-metal cyanide (DMC) complex exhibits high catalytic activity for esterification of fatty acids (FA) with glycerol. DMC catalysts with varying acidities were prepared by synthesizing the material at four different temperatures (10, 25, 50 and 80 °C). The catalyst prepared at 50 °C exhibited highest catalytic activity. Catalytic activity of DMC was influenced by both acidity and surface area. Complete conversion of FA was achieved at 140–200 °C under atmospheric pressure. Chain length of FA was found to influence the rate of reaction and product selectivity.

Graphical abstractThe application of double-metal cyanide (DMC) catalysts for esterification of fatty acids with glycerol is reported for the first time. Complete conversion of fatty acid is achieved at 140–200 °C under atmospheric pressure. Catalytic activity of DMC is influenced by both acidity and surface area.Figure optionsDownload full-size imageDownload as PowerPoint slideResearch highlights► Fatty acid glycerides are important in pharmaceuticals, cosmetics, etc. production. ► Their synthesis using double-metal cyanide catalysts is reported for the first time. ► Complete conversion of FA is achieved at 140–200 °C under 1 atm pressure. ► Catalytic activity of DMC is influenced by both acidity and surface area.
