Transesterification of sunflower oil [8], rapeseed oil [9], soybean
oil and beef tallow [10] for biodiesel has been reported. Biodiesel
are produced by esterification of free fatty acids (FFA) or transesterification
of oils and fats with short chain alcohols. For most
technical applications methanol is used because it is available as
an anhydrous, low-priced and active alcohol. Therefore, biodiesel
fatty acid alkyl esters (FAAEs) most commonly refers to fatty acid
methyl esters (FAMEs).
