optimized by performing the reactions at varied temperature ranging from 70 to 85 C and the temperature at 76 C was found critical for getting maximum yield of CME 2(Fig. 2). Table 3 demonstrates the profile of CME yield at constant temperature and concentration of catalyst obtained by different trials. Each value is the mean of five repeats. An average yield of 900 mL CME and 115 mL glycerol were recovered from one litre of coconut oil by transesterification. No difference was observed in the amount of purified CME after the recovery of methanol and moisture by separation and distillation processing. The partialpurification of the crude glycerol fraction showed an average yield of 70–80% glycerol.
