Recently, advanced technology of microwave has been an attention for biodiesel synthesis.
Nyamplung seed oil (Callophylum inophyllum) containing oil with high free fatty acid (FFA).
This oil was utilizied as a non-edible oil feedstock for biodiesel production. Microwave
technology used as heating system for esterification process to reduce the FFA content for
produce a high-quality product. Ionic liquid is used as enviromentally-friendly and promising
acid catalyst for biodiesel syntesis owing to their benefical characteristics such as high catalytic
activity, high selectivity, and available to recycling. In this paper, 1-Butyl-3methylimidazolium hydgen sulfate BMIMHSO4 was used as a catalyst and microwave as
heating system for esterification reaction of Callophylum inophyllum seed oil. The object of
this paper are to know about kinetic model in esterification reaction and kinetics parameters
such as activation energy (E) and frequency factor (A). The results indicated that microwaveassisted esterification was of pseudo-homogen second-order reaction with the activation energy
of 2830 J/mol and frequency factor (A) 3,86 minutes-1 using 15% catalyst and molar ratio
oil:methanol was 1:40.
