Bio diesel
Jun 03 2014

Biodiesel is obtained by transferring vegetable oils or animal fats into alkyl esters of their fatty acids. However, the amount of free glycerol as a by-product of the biodiesel production, together with remaining amounts of unreacted triacylglycerides and partially reacted mono- and diacylglycerides, play an important role for the fuel quality. These compounds should be absent in the ideal case.
