Soybean Biodiesel Production: For the production of biodiesel, the transesterification reaction of the soybean oil with methanol was carried out by the alkaline route (KOH). Moreover, the biofuel is expected to be continuing in the foreseeable future and the reading of the biofuels features dealt with in this book, are mentioned for any person interested in understanding this varied and evolving subject." Biodiesel is a renewable fuel made from organic feed sources.

With the increase of CG loading from 0% -15%, the hydroxyl value increased from 478 mg KOH/g to 592 mg KOH/g. This is most likely due to the high hydroxyl value of glycerol (1829 mg KOH/g).
