This is Trans esterification as a reaction to a change in molecularTriglycerides. A major component of the oil palm is ester or mono-alkylester and glycerol. The small molecules react with alcohol (methanol) in the presence of a catalyst.( Sodium supported on ceramic rink) The proportion of methanol to palm oil through the reduction of free fatty acids is 18:1 by mole. With sodium carbonate supported on ceramic rink. (Na2CO3/Ceramic rings)
