Enhancement of Heterogeneous Ethyl Oleate Synthesis Using Aqueous Ethanol

Enhancement of Heterogeneous Ethyl Oleate Synthesis Using Aqueous Ethanol

Biodiesel synthesis using heterogenous catalyst usually results in compromise rate of reaction due to mass transfer limitation during the reaction. An alternative is reported in this paper to produce biodiesel from free fatty acids in a liquid-liquid system using immobilized lipase. The yield of rev...
