Transesterification (Biodiesel Production)

triglyceride + 3CH3OH → 3 FAME + glycerol

अवलोकन

Triglyceride fats react with methanol in the presence of a base catalyst to produce fatty acid methyl esters (FAME, biodiesel) and glycerol. Each triglyceride molecule produces three molecules of biodiesel. This transesterification reaction replaces glycerol with methanol at the ester linkages.
