摘要: Abstract At present, alkali-catalyzed transesterification process is widely used in biodiesel production. However, this up to 88% of total production cost for the feedstock, due requirement using low free fatty acid (FFA) content feedstocks that are commonly attributed refined edible plant-oils. This work was, therefore, carried out know potential use non-edible Pongamia pinnata oil Instead a transesterification, applied an interesterification called one-step supercritical methyl acetate method under reaction condition 300 °C/20 MPa/45 min/42 M ratio oil. In glycerol-free method, 10wt% aqueous acetic was added as additive proceed such condition. It found high FFA did not give any adverse effect on highest yield 96.6wt% FAME and 11.5wt% triacetin (total 108.1wt%) achievable. Both products were miscible their evaluation properties showed compliance towards standards.
