One of the researches being developed is to produce methyl esters from CPO through transesterification reaction of vegetable oil (triglycerides) with methanol. Biodiesel from crude palm oil is a new hope for answering some of the energy needs. know the rate of combustion of the biodiesel produced. Biodiesel that is produced from a mixture of CPO, phosphoric acid and sodium hydroxide, with a percentage of I. 98% CPO, 1% Phosphoric Acid, 1% Sodium Hydroxide: II. 95% CPO, 2% Phosphoric Acid, 3% Sodium Hydroxide: III. 95% CPO, 3% Phosphoric Acid, 2% Sodium Hydroxide. The results showed that the most effective mixture was 95% CPO, 3% acid phosphate and 2% sodium hydroxide with a burning rate of 0.309 g / minute in 30.42 minutes with a final temperature of 57 (oC).
