Abstract
Biodiesel is produced by a chemical reaction known as transesterification in which a triglyceride
reacts with a primary alcohol to give an alkyl ester Biodiesel and a byproduct Glycerol. The
reaction is said to proceed to completion only when the primary alcohol is in excess, but there has
not been any Mathematical Model to support the claim. The problem statement as formulated and
analyzed in this paper justifies the need to use excess primary alcohol for the reaction.
