The major ingredients for producing biodiesel include oil methanol ethanol and, or, either lye or potassium hydroxide.? Biodiesel is produced by the chemical reaction of a fat with a simple alcohol (methanol or ethanol) in the process of, transesterification. Transesterification is a fairly basic organic chemistry reaction where more complex fat and / or oil molecules known as triglycerides. Break down into simpler fat and / or oil molecules known as monoglycerides and replace one form of alcohol (glycerine with.) Another (methanol). The rate of the chemical reaction is sped up by the use of a catalyst. In addition to the production. Of biodiesel the transesterification, reaction also yields a small amount of glycerol. For example 100 pounds, of oil plus 10 pounds. Of methanol or ethanol will yield approximately 100 pounds of biodiesel and 10 pounds of glycerol. As a result of increased. Global, biodiesel production there is a surplus of glycerol and little or no market. The color of biodiesel ranges from. Golden to dark brown with most feedstocks. However hemp-based biodiesel, results in a green-colored fuel.
