| Abstract: | Propan-2-ol was used as an acyl acceptor for immobilized lipase-catalyzed preparation of biodiesel. The optimum conditions
for transesterification of crude jatropha (Jatropha curcas), karanj (Pongamia pinnata) and sunflower (Helianthus annuus) oils were 10% Novozym-435 (immobilized Candida antarctica lipase B) based on oil weight, alcohol to oil molar ratio of 4:1 at 50 °C for 8 h. The maximum conversions achieved using
propan-2-ol were 92.8, 91.7 and 93.4% from crude jatropha, karanj and sunflower oils, respectively. Reusability of the lipase
was maintained over 12 repeated cycles with propan-2-ol while it reached to zero by 7th cycle when methanol was used as an acyl acceptor, under standard reaction conditions.
