Abstract
Various embodiments of the present invention are directed to processes and methods for converting lipids comprising fatty acids into fatty esters. According to various embodiments of the invention, the saponifiable lipids are reacted with a base to form alkali soaps. The alkali soaps are then reacted with an acid to form fatty esters. Both the base reaction and the acid reaction may occur in the presence of one or more alcohols. Following the acid reaction, a solvent may be added to effect a separation of the fatty esters, which may then be recovered.
