Transesterification of Castor Oil by Using Methanol and Ethanol (50/50) Mixture


Biodiesel is gaining considerable attention as a renewable sourceof energy, as an alternative to petroleum fuel and can be used in enginewithout modification in this paper, the profile of preparation of fatty acidmethyl ethyl ester from castor oil via a base-catalyzed transesterification wasinvestigated.. The variables chosen for the study were reaction time, oil to(methanol and ethanol) mixture ratio, and reaction temperature at constantconcentration of KOH(catalyst) .The effects of these variables on viscosity andspecific gravity were studied.
