Research ArticleOpen accessIn the abstractLIPASE-CATALYZED TRANSESTERIFICATION OF PALM KERNEL OIL WITH DIALKYLCARBONATESTjahjono Herawan, M. Rüsch Gen. KlaasLipase-catalyzed transesterifications-especially in a solvent-free medium-are important for industrial applications because such systems would have an enormous advantage by avoiding the problem of separation, toxicity and flammability of organic solvents. However, the organic solvent-free alcoholysis, especially methanolysis, does not give high conversions. The same problem also occurs when ethyl or methyl acetate are used as acyl acceptors. The main problems … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 6 May 2014 · 6,793 accessesView PDFCite
