Kinetics of Enzyme-Catalyzed Alcoholysis of Soybean Oil in <I>n</I>-Hexane

Abstract

This work investigated the production of fatty acid ethyl esters (FAEEs) from soybean oil using n-hexane as solvent and two commercial lipases as catalysts, Novozym 435 and Lipozyme IM. A Taguchi experimental design was adopted considering the variables temperature (35-65 degrees C), addition of water (0-10 wt/wt%), enzyme (5-20 wt/wt%) concentration, and oil-to-ethanol molar ratio (1:3-1:10). It is shown that complete conversion in FAEE is achieved for some experimental conditions. The effects of process variables on reaction conversion and kinetics of the enzymatic reactions are presented for all experimental conditions investigated in the factorial design.

Lipid storage compounds in raw activated sludge microorganisms for biofuels and oleochemicals production

“…acid, base, enzyme). 6,7 Depending on the nature of the lipid feedstock and the applied catalyst, the reaction is called either transesterification or esterification. 8 In contrast, renewable diesel is comprised of organic compounds similar to those contained in petroleum diesel.…”

Improved Enzymatic Procedure for the Synthesis of Anandamide and N‐Fatty Acylalkanolamine Analogues: A Combination Strategy to Antitumor Activity

“…The enzymatic synthesis of linolenic acid ethyl ester has been reported by alcoholysis of soybean oil in hexane or compressed fluids, affording the ester in a complex mixture of fatty acid ethyl esters. [33] Another approach has employed lipase in the presence of activated molecular sieves in a reflux trap. [34] In the present work, five lipases from several sources were applied.…”
