AB  - In the present study, a lab scale microwave
reactor was used to conduct the esterification and
transesterification of Dairy Scum Oil (DSO). 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.
