The transesterification of methyl butyrate, ethyl butyrate and butyl butyrate to geranyl butyrate was investigated in supercritical carbon dioxide. The effect of chain length of the butyrate on the rate of transesterification was investigated. The initial rates followed the trend: ethyl butyrate<butyl butyrate<methyl butyrate. The transesterification of butyl butyrate to geranyl butyrate in...
Biodiesel, an alternative biodegradable diesel fuel, is derived from triglycerides by transesterification with alcohols. In this work, the transesterification of sunflower oil was investigated in supercritical methanol and supercritical ethanol at various temperatures (200-400 o C) at 200 bar. The rate coefficients and the activation energies of the reaction were also determined. Biodiesel...
