Abstract

Biodiesel is gaining considerable attention as a renewable source
of energy, as an alternative to petroleum fuel and can be used in engine
without modification in this paper, the profile of preparation of fatty acid
methyl ethyl ester from castor oil via a base-catalyzed transesterification was
investigated.. The variables chosen for the study were reaction time, oil to
(methanol and ethanol) mixture ratio, and reaction temperature at constant
concentration of KOH(catalyst) .The effects of these variables on viscosity and
specific gravity were studied.
