Glicerol: um breve histórico e aplicação em sínteses estereosseletivas

Abstract: Recebido em 18/4/10; aceito em 21/8/10; publicado na web em 8/12/10 GLYCEROL: A BRIEF HISTORY AND THEIR APPLICATION IN STEREOSELECTIVE SYNTHESES. Presently glycerol is considered a co-product of biodiesel industry. As the biodiesel production is exponentially increasing, glycerol generated from the transesterification of vegetable oils and fats is also being produced on a large scale, and turned out to be essential seeking for novel alternatives to the consumption of the extra volume, in crude and/or as deriva… Show more

“…As the main production process of biodiesel is a chemical route using basic catalysts, crude glycerin contains diverse impurities such as alcohol, traces of the catalyst, esters, and salts that hinder its direct application in several industrial processes. Nowadays, the main industrial sectors that consume glycerin worldwide are cosmetics, soaps, and pharmaceuticals [22,23] that require glycerin with certain degree of purity. The purification of crude glycerin obtained from biodiesel production to transform it into analytical grade is not economically favorable for sectors that work with lower value-added products [24].…”
