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