Document Summary
Mixture of methyl esters of fatty acids derived from vegetable oils. Prepared by alkali catalyzed transesteri cation of oil with methanol. Yields a mixture of methyl esters and glycerol ( glycerin ) Rapid reaction , 98% reaction ef ciency end product must be re ned. Soybean oil, palm oil, and canola/ rapeseed oil are conn only used as the feedstock. Other low grade oils, used frying oils. Oils with a lower degree of unsaturated are preferred due to their greater oxidative stability. Oils with a higher degree of unsaturated are better suited for colder climates due to their lower melting points. Methyl esters of fatty acids are also used as solvents. Derived by pressing the fruit of the oil palm, which is widely grown in southeast asia and. Solid fraction from palm oil is used as the solid fat component in margarine and shortenings. Use in biodiesel is growing - sustainability issues, food vs fuel issues.
