Study on the Solvent Power of a New Green Solvent: Biodiesel

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…
