This article describes a facile one-pot synthesis of bio-diesel from non-treated Jatropha oil (J oil) with high acid value (ca. 17 mg KOH/g). Choline hydroxide exhibited superior catalytic activity than choline im-idazole in the transesterification that yields 95 ± 1% of biodiesel, when the reaction was carried out with 9 : 1 molar ratio of methanol to J oil and 4 wt% catalysts at 60°C for 4 h. Further study showed that the catalyst exhibited almost constant activity for four successive trials after being recycled. The main fuel properties of the final product meets the ASTM standards. Moreo-ver, the properties of biodiesel are identical to those obtained by conventional method (US 7,666,234 B2) and can be used as fuel in the existing diesel engines without any modification.

Moreo-ver, the properties of biodiesel are identical to those obtained by conventional method (US 7,666,234 B2) and can be used as fuel in the existing diesel engines without any modification.
