摘要：

The polyol, trimethylolproprane (2-ethyl-2-hydroxymethyl-1,3-propanediol), and a mixture of rapeseed oil fatty acid methyl esters were transesterified by immobilized lipases without additional organic solvent. The conversion to the polyol tri-ester with immobilized Rhizomucor miehei 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% was reached in 66 h.
