A series of pyridinium ionic liquids were synthesized and characterized. Acid-catalyzed transesterifications of Jatropha oil were carried out with these ionic liquids under mild reaction conditions. [BSPy]CF3SO3 showed the best catalytic activity and biphasic behavior in the proposed process. The products could simply be separated from the catalyst phase. The catalyst exhibited constant activity for seven successive cycles after being recycled.
