| Research Abstract |
The amount of water needed to purify crude biodiesel fuel (BDF), which was synthesized using alkali catalysts, was studied experimentally and theoretically. It depended on the species of soap, the initial concentration of alkali metal and the extraction temperature. For example, 35mg-K/kg of potassium oleate can be extracted at 353K from methyl oleate using 0.16 % of water, which is one 1,875th of water amount in a conventional purification process.
