This acid to the backward reaction i.e. recombination of glycerol and esters, thus decreasing the biodiesel yield. Therefor , it must be noted that the transesterification reaction is reversible in nature and therefor large amount of alcohol is required to keep the reaction in the forward direction[18]. Jain and Sharma [15] observed when methanol was increased from 10% to 30% (v/v), maximum yield of 90.6% was achieved. It has been observed that as the molar ratio increases, biodiesel yield also increases but start dropping after achieving peak. It has also been found in the literature that fatty acid ethyl esters (FAEEs) have better fuel properties compared to methyl esters but separation of former is difficult[39].
