Fatty Acid Methyl Ester Formulas and Properties
Fatty acid methyl esters (FAMEs) are a type of hydrocarbon compounds formed by the reaction of fatty acids with methanol. The general chemical formula for FAMEs is R-COOCH3, where R represents a hydrophobic radical.
FAMEs possess several key properties that make them valuable in numerous applications. They are generally viscous at room temperature and have minimal solubility in water due to their hydrophobic nature.
FAMEs exhibit superior thermal stability, making them suitable for use as fuels and lubricants. Their oxidative resistance also contributes to their durability and longevity.
