Refined methyl, ethyl, propyl, 1-butyl, and 2-butyl biodiesels as well as unrefined methyl biodiesels containing glycerides were prepared, and their solvent power was evaluated by measuring the kauri-butanol value. By analysis of the kauri-butanol values of biodiesels with different fatty acid profiles and different alcohol types, some interesting results were obtained. The pure methyl este…
The transesterification of triacetin to methyl acetate catalyzed by 11 kinds of low boiling point amines was examined at subcritical methanol temperature as model reactions to simulate the biodiesel production. It was found that the branched amines showed higher yield of methyl acetate than normal amines. For normal amines, the yield of methyl acetate decreased with the increase of the carbo…
