As is known, the traditional technology of BD have severaldisadvantages, one of which is a lot of wastes and difficulties on the stages ofseparation of the products of transesterification reaction like: glycerol, mono-, diglycerides,biodiesel, and salts of fatty acids. The problem of separation iscomplicating if for rational use and for improving of economic indicator themanufacturers use waste vegetable oil as a raw material (after restaurant and Fastfoods)with a high content of free fatty acids.As an alternative solution of this problem, we decided to divide the process ofproduction of Biodiesel from vegetable oil into two stages. On the first stage thevegetable oil was hydrolyzed, and after a mixture of free fatty acids, mono, di- andthree glyceride formation the product was mixed with methanol. By varying thepressure, temperature and time of the reaction the yield of methyl esters of fattyacids after the second stage was determined.In two stages process there is no problem in separation and isolation of thereaction products. The other preference of two stages process is high rates of theboth stages of hydrolysis and the final FAME formation without any special catalyst.The character of the reaction of esterification with methanol clearly showsautocatalytic contribution of the free fatty acids.Thus, comparing the rate of esterification with the sum of rates of hydrolysis andsubsequent esterification, we concluded that the design of two stages technology willbe very interesting, profitable and environmentally feasible.489
