Lipase-catalyzed glycerolysis in ionic liquids directed towards diglyceride synthesis

Process Biochemistry, 2009
Abstract This work examined the lipase-catalyzed glycerolysis of triglycerides (TG) in a list of commercially available ionic liquids (ILs) with varied cations and anions for the purpose of developing an efficient reaction protocol for diglyceride (DG) production and to understand whether ILs could assist the reaction systems.

Evaluation on potential application of lipase immobilized on rice husks in enzymatic glycerolysis reaction

Owing to high production cost and low reaction yield, immobilized lipase is rarely used in industrial glycerolysis. This research characterizes the performance of lipase immobilized on rice husk in glycerolysis reaction. By utilizing hexamethylenediamine

Microwave-irradiated zinc chloride catalyzed glycerolysis of high free fatty acid vegetable oil

, 2015
Biodiesel, a popular alternative to fossil-based diesel, can be produced from cheap and sustainable sources like waste cooking oil. However, waste cooking oil, with its inherent FFA content, requires a pre-treatment step to lower the FFA content, making ...

Application of a novel solid superbase catalyst of Na2O/molecular sieve analogs (HND-63) in synthesis of plant-based monoglyceride and its catalytic mechanism

Grain & Oil Science and Technology
Monoglyceride (MAG) is a widely used nonionic surfactant. In this work, an economic and green solid superbase HND-63 was utilized to synthesize monoglyceride, and the independent variables were examined to achieve the highest MAG content.
