摘要: Aliphatic alcohols of chain lengths 24-34 carbons have been found to be beneficial in treating hypercholesterolemia. Approximately 40% beeswax is long-chain esters which can transesterified supercritical carbon dioxide give these and fatty acid methyl esters. The methanolysis reaction was catalyzed by an immobilized lipase from Candida antarctica flowing the were then isolated precipitation heptane. following percentages: tetracosanol, 9.1; hexacosanol, 14.0; octacosanol, 18.4; triacontanol, 37.2; dotriacontanol, 21.1; tetratriacontanol, 0.3. utility method demonstrated isolating jojoba oil a mixture triglycerides waxes corn bran.
