Current State and Perspectives on Transesterification of Triglycerides for Biodiesel Production

Catalysts, 2021
Triglycerides are the main constituents of lipids, which are the fatty acids of glycerol. Natural organic triglycerides (viz. virgin vegetable oils, recycled cooking oils, and animal fats) are the main sources for biodiesel production.
