A by-product in oleochemistry, glycerol is a three carbon compound produced by the saponification, hydrolysis and transesterification of lipid triacylglycerol. In biodiesel anufacturing process, the amount of glycerol accumulated is presumed by a tenth of that of biodiesel synthesized. Mass production of biodiesel in universe allowed a considerable decrease in glycerol price, of which crude type is estimated 40￠/kg at around 2010. To obtain the price competitiveness of biodiesel, the conversion of glycerol to high value-added chemical compounds should be necessary. Among glycerol derivatives such as glycerol carbonate, glycerol ester, 1,3-propanediol, the biosynthesis of 3-hydroxypropionic acid (3-HP), one of "the top-value added chemicals from biomass" chosen by U.S. Department of Energy1), is introduced in this presentation. 3-HP is a none-chiral organic acid with three carbons and can be used as a chemical intermediate to synthesize acrylic acid, acrylamide, malonic acid and 1,3-propanediol.
Chemical and biotechnological approaches for 3-HP production have been proposed but commercially available processes were not developed to date2). Here some challenges and obstacles for the production of 3-HP from glycerol will be presented.
