The optimum parameters for acid catalysed esterification were: Microwave power-600 W, molar ratio of methanol to FFA-30:1, Temperature of reaction-60°C, concentration of sulphuric acid-8% by wt. while the optimum parameters for transesterification were: Temperature-60°C, Microwave power-600 W, molar ratio of methanol to DSO-7:1, concentration of KOH-1% (by wt.). Experiments conducted under optimum conditions both in microwave reactor and conventional electrically heated reactor revealed that, a highest conversion of FFA was 93.63% (reaction time-16 min) while a highest yield of FAMEs in transesterification was 93.47 (reaction time-5 min) in microwave reactor. Kinetic studies conducted in microwave reactor showed that, esterification and transesterification followed pseudo first order kinetics. ER -
