Evaluation of the use of surfactants as additives in enzymatic glycerolysis reactions

, 2012
MAGs and DAGs are widely used as emulsifiers in many industries. During glycerolysis reactions for their production, the immiscibility of the glycerol and the oil phases is an important drawback for practical purposes.

Glicerólise de óleo de peixe catalisada por lipase comercial de Rhizomucor miehei em meio com surfactante de grau alimentício Glycerolysis of fish oil catalyzed by a commercial lipase from Rhizomucor miehei in reaction media containing food grade surfactant

Química Nova, 2013
Omega-3 enriched partial acylglycerols are beneficial for human health. The aim of this study was to obtain monoacylglycerols (MAG) and diacylglycerols (DAG) by means of glycerolysis of fish oil catalyzed by a lipase from Rhizomucor miehei in the ...

Sustainable polyurethane coatings derived from alkyds of Camelina oil monoglycerides

Journal of Applied Polymer Science, Volume 141, Issue 41, November 5, 2024.
This study presents the use of immobilized lipase for a low‐temperature glycerolysis reaction to produce monoglycerides. Monoglycerides were then reacted with dibasic acids to produce alkyd diols. The produced alkyd diols were incorporated into polyurethane formulations and were applied on metal substrates.

Chemical transesterification of coconut and corn oils using different metal hydroxides as catalysts to determine the chemical and physiochemical changes to the oils

Journal of the Science of Food and Agriculture, Volume 104, Issue 14, Page 8801-8812, November 2024.
Abstract BACKGROUND The transesterification of butteroil has been shown to alter its lipid chemistry and thus alter the crystallization of the fat. The reaction kinetics and resulting crystallization of the butteroil differ depending on the nature of the catalyst used.

Glycerolysis–interesterification in high-shear reactor using sodium silicate catalyst: effect of mixing rate on reaction kinetics

, 2023
High-shear reactor (HSR) was used to improve glycerolysis-interesterification of immiscible fluids (palm stearin-olein blend and glycerol) to synthesize products containing high monoacylglycerol (MAG) and diacylglycerol (DAG).

Green synthesis of highly active and recyclable chromium oxide nanocatalyst for biodiesel production from novel nonedible oil seeds

GCB Bioenergy, Volume 16, Issue 5, May 2024.
Herein, we produced biodiesel using nonedible and poisonous Phyllanthus maderaspatensis oil seeds, which have the highest seed oil content (35%), coupled with a lower free fatty acid content (0.87 mg/KOH), making them an ideal candidate for producing biodiesel.

Liquid‐Liquid Phase Equilibrium of Glycerolysis Precursors: Experimental and Modeling Study

Chemical Engineering &Technology, Volume 47, Issue 1, Page 208-216, January 2024.
Glycerol and oleic acid are mutually immiscible components. Their rigorous reaction produces glycerol esters and water. Such mutual immiscibility of glycerol and free fatty acids limits glycerolysis, a reaction capable of upgrading waste‐derived oils. The glycerol solubility in the fatty phase increases when glycerol esters are added to the immiscible ...
