Glycerol conversion to lactic acid in the presence of platinum based catalysts.

Abstract

International @ BIOVERT+JFT:MBE:LDJ:CPIInternational audienceIn the last decade, lactic acid (LA) became an important feedstock, with an annual production of 120,000 tonnes. This importance comes from its use in: i) food-industry: as a food acidulant or as a bacterial spoilage inhibitor and (ii) as a new raw material to produce biodegradable thermoplastics. Nowadays, the LA production is mainly ensured by a saccharide fermentation route; nevertheless, this process still needs improvement. We have previously shown that lactic acid can be obtained from glycerol in the presence of iridium or rhodium-based catalysts. In this present work we introduce the LA obtainment from glycerol (Gly) in the presence of platinum (Pt) - based catalysts
