Yy. Linko et al., PRODUCTION OF TRIMETHYLOLPROPANE ESTERS OF RAPESEED OIL FATTY-ACIDS BY IMMOBILIZED LIPASE, Biotechnology techniques, 11(12), 1997, pp. 889-892
The polyol, trimethylolproprane (2-ethyl-2-hydroxymethyl-1,3-propanedi
ol), and a mixture of rapeseed oil fatty acid methyl esters were trans
esterified by immobilized lipases without additional organic solvent.
The conversion to the polyol tri-ester with immobilized Rhizomucor mie
hei lipase Lipozyme IM 20 was about 75% after 24 h at 58 degrees C, 5.
3 kPa, with no added water, and the highest conversion of about 90% wa
s reached in 66 h.
