In this study, the enzymatic transesterification of castor oil with methanol in a solvent free media is carried out using
lipase catalyst. The influence of several operation conditions (i.e. the amount of enzyme, molar ratio of methanol to
castor oil, reaction temperature and reaction time) on the production of biodiesel was analyzed. It is observed that with
increase in molar ratio, reaction time and enzyme amount, the amount of product (biodiesel) increased. When reaction
temperature increased, the amount of biodiesel increased firstly and then decreased. The optimum value for amount of
enzyme, molar ratio of methanol to oil and temperature was 300 mg, 9:1 and 55°C, respectively. The maximum
concentration of methyl ester was 2298 ppm after 72 hours.
