Among the basic oleochemicals, glycerol is considered as the primary base because the preparation of all others must somehow yield glycerol at one point or other. However, saponification, esterification (methyl esters production) and hydrolysis of fats are the major principal processes used to produce natural glycerol. These processes are mainly carried out in soap and fatty acid plants in the oleochemical industry. Since its discovery in 1779, glycerol has been the subject of much research. A review of the literature revealed a wide spectrum of work that has been and can be done. For the purpose of this paper, some complexes of glycerol and their applications will be highlighted.
