Highly efficient catalyst for the decarbonylation of lactic acid to acetaldehyde

High yield lactic acid selective oxidation into acetic acid over a Mo-V-Nb mixed oxide catalyst

“…As examples, the synthesis of hydrogen, of liquid fuels and of precursors for plastics from renewable resources, catalysis plays a very important role [4,5]. In this context, lactic acid, which is often referred as a "sleeping giant", has attracted much attention as an alternative resource for the production of important chemicals such as acrylic acid, 1,2-propanediol, 2,3-pentanedione, pyruvic acid, [6] acetaldehyde [7] and mainly the polylactic acid (PLA) polymer [8,9]. Lactic acid can be easily be obtained by fermentation of renewable sources such as sugars and starches or even waste streams (cheesy whey for instance) [10][11][12].…”

An efficient one pot conversion of glycerol to lactic acid using bimetallic gold-platinum catalysts on a nanocrystalline CeO2 support

“…It also has applications in the food, cosmetic, and pharmaceutical industry [24]. Lactic acid is considered a top 12 biobased platform molecule and may serve as a starting point for a wide range of future biobased chemicals by catalytic routes [26], [27]. Lactic acid can be produced either chemically or biotechnologically by fermentation routes.…”

ORIGINAL RESEARCH: Direct fermentation oftriticale starch to lactic acid byRhizopus oryzae

“…[4][5][6][7] In the chemical industry, via decarboxylation, decarbonylation, dehydration, or reduction with hydrogen, LA can be converted to commodity chemicals such as acetaldehyde, acrylic acid, and pro panoic acid. 8 Fermentative production of LA by microbes, in contrast to chemical synthesis, e.g., by hydrolysis of lactonitrile using strong acids, has several advantages, most importantly, the production of optically pure L(+) or D(-)-lactic acid instead of a racemic mixture. [2][3][4]9,10 The L(+)-isomer is the biologically important isomer and is a preferred substrate in most industrial applications.…”
