Abstract:

The esterification of free fatty acids (FFA) with methanol is studied using Sulfonated Porous Carbon (SPC) as catalyst. In compare to the amorphous sugar catalyst and protonated Nafion, the proposed catalyst shows stability and high efficient performance in biodiesel production. The highest initial rate of oleic acid conversion is obtained at catalyst loading of 1 mmol H+ and mole ratio of MeOH/Oleic acid of 10. The prepared Sulfonated Porous Carbon reused at least three times without loss of activity.

Ultrasonic free fatty acids esterification in tobacco and canola oil.

Ultrasound accelerates the free fatty acids esterification rate by reducing the mass transfer resistance between methanol in the liquid phase and absorbed organic species on Amberlyst®46 catalyst. The reaction rates of canola oil is three times greater than for tobacco seed oil but half the reaction rate of pure oleic acid as measured in a batch reactor. The beneficial effects of ultrasound vs....

Relation of fatty acid structure to release and esterification of free fatty acids.

HOLLENBERG, C. H., AND A. ANGEL. Relation of fatty acid structure to release and esterijication of free fatty acids. Am. J. Physiol. 205(5): 909-912. I g63.-After incubation of rat adipose tissue with corticotrophin in buffer-albumin, the composition of the free fatty acids (FFA) in the tissue and in the medium was determined; the medium contained proportionately more myristic, palmitoleic, lin...

Novel biocatalytic esterification reactions on fatty acids:

Aspergillus terreus lipase has exhibited novel capability of catalyzing esterification reaction between fatty acids (C4-C18) and primary, secondary and tertiary monohydric alcohols. Although, the lipase efficiently catalyzed the esterification of saturated stearic acid (C18:0), it failed to accept the monounsaturated oleic acid (C18:1) as the substrate which is also a C18 acid, but has a double...

Mechanism of free fatty acid re-esterification

Within adipose tissue, free fatty acids liberated by lipolysis may be re-esterified into newly synthesized triacylglycerol. We hypothesized that re-esterification may occur via an extracellular route, such that free fatty acids arising from lipolysis must leave the adipocyte and be taken up again before they can be re-esterified. We simultaneously measured rates of lipolysis, acylglycerol synth...
