Abstract
In the present work, in-situ methanolysis of microwave irradiation heat pre-treated Jatropha curcas l oil in the presence of alkaline benzyltrimethylammonium hydroxide (BTMAOH) as a phase transfer catalysis (PTC) was investigated. Combined use of microwave heat pretreatment of Jatropha curcas l seed particles and alkaline BTMAOH as a PTC drastically reduced the reaction time from 240 to 30 min. The yield of fatty acid methyl ester (FAME) was also increased from 49.7 to 93.5 %. Reaction kinetics was investigated to study the extent of reaction rate. Reaction kinetic study demonstrated that the order of the reaction is a first order reaction at all reaction temperature under investigation. Activation energy of the reaction was found to be 21,641 J/mole. Combined use of microwave heat treatment of Jatropha curcas l seed particles and PTC is promising to enhance the reaction rate of in-situ methanolysis.
