Effect of various alcohols in Trans-Esterification of Palm Oil (CPO) with CaO-MgO Catalyst

The purpose of this research is the synthesis alkyl esters from CPO through transesterification reaction using catalyst CaO-MgO. This experimental laboratory stages: (1) refinement, (2) determination free fatty acid numbers, (3) activation CaO-MgO catalysts, (5) with alcohol (methanol and ethanol), (6) identification components synthesized ester GC-MS,characterization including density, viscosity, refractive index number test. results showed that can be methanol catalysts a yield 85.72%, while transformation ethanol difficult to form ethyl ether character methyl ester: density 0.86 g/mL, viscosity 3.23 cSt, 1.44819, 0.747 mg KOH/g ester, main component contains 1.20% myristic compound, palmitate 40.637% linoleate 9.332%, 7-octadecenoate 42.986%, stearate 4.427%.
