title: Fast, easy ethanolysis of coconut oil for biodiesel production assisted by ultrasonication.
abstract: Biodiesel is a renewable fuel, consistituting an alternative to petroleum-based diesel fuel. It is non-toxic and biodegradable and has a low emission profile, is better from environmentally sensitive areas. Research study on alternative fuels is essential for increased energy security. Presently, biodiesel is produced mainly is batch reactor. In this process the required energy is given by heating accompanied by mechanical stirring which has several disadvantages because of time consuming high labour cost. Being methanol is a toxic chemical; the objective of this work is to produce coconut oil ethyl ester by using ultrasonic irradiation. The advantages of ethanol are non-toxic domestic all available, having higher carbon atoms which provide higher heat content. The optical conditions for biodiesel production is the molar ratio oil to ethanol 1:6, KOH catalyst 0.75wt.% of oil and 7min reaction time. The reaction time reduced 15-40 times comparing to the conventional batch processes and found >or=98% biodiesel yield.
