“…Recently, homogeneous metal salts have also been reported to catalyse this transformation [45,46]. A parallel undesired pathway involves the catalytic oxidation of glyceraldehyde/dihydroxyacetone to glyceric acid and subsequently to further oxidation and C-C splitting products like tartronic acid, glycolic acid, oxalic acid, acetic acid and formic…”

The one pot conversion of glycerol to lactic acid using monometallic Au and Pt as well as bimetallic (Au-Pt) catalysts supported on nanocrystalline CeO2 (n-CeO2) in aqueous solution in the presence of a base and oxygen was investigated. Catalytic performance of the bimetallic catalysts is considerably better than the monometallic ones and is indicative for synergistic effects. The bimetallic system shows excellent activity (TOF = 1170 h -1 ) with a high selectivity (80%) to lactic acid at 99% glycerol conversion (373 K, NaOH to glycerol ratio of 4 mol/mol 5 bar oxygen). The Au-Pt/nCeO2 catalyst was recycled 5 times in a batch set-up without a significant drop in activity and lactic acid selectivity, indicative for good catalyst stability.3

“…Hence, it is widely used in the food, pharmaceutical, cosmetic, and chemical industries. LA in particular has received much attention recently as a monomer for the production of biodegradable polylactic acid (PLA) or polylactide (Hayashi and Sasaki 2005;de Clippel et al 2012). Currently, lactic acid is produced by the fermentation method.…”

Lactic acid (LA) is a potential platform chemical that can be produced from lignocellulosic biomass. The development of a cost-competitive, catalyticbased LA production system is gaining significant attention in modern biorefineries. A series of experimental study was carried out to investigate the chemocatalytic effect of the conversion of oil palm empty fruit bunch (EFB) fibers into lactic acid under hydrothermal conditions. Synthesis of chemicals from lignocellulosic biomass involves complex mechanisms because of the complex composition of the biomass. Therefore, experimental parameters, i.e., temperature, Pb(II) concentration, and reaction time were studied. It was found that production of LA is highly dependent on the experimental conditions. In this study, the highest LA yield obtained from EFB fibers was > 46% (230 °C, 2 mM Pb(II) after 4 h of reaction). However, a similar yield can be achieved either using higher Pb(II) and shorter reactions time or vice versa. The selective production of chemical compounds (glucose, 5-hydroxymethyl furfural (5-HMF), furfural, levulinic acid, and lactic acid) from EFB fibers is highly dependent on the availability of Pb(II) ions.

“…Alternative chemocatalytic approaches toward lactic acid and alkyl lactates from carbohydrates are therefore of great interest. [17][18][19][20][21][22][23][24] One of the key reaction steps in this regard is the rearrangement of the pyruvic aldehyde intermediate to lactate via a hydride shift mechanism. [23,25] Zeolites and mesoporous silica materials containing Lewis acidic functional groups have attracted attention as promising catalysts for carbohydrate isomerization reactions.…”

Highly Active and Recyclable Sn‐MWW Zeolite Catalyst for Sugar Conversion to Methyl Lactate and Lactic Acid

et al. 2013

Not just sugar! Lewis‐acidic Sn‐MWW zeolites are obtained through postsynthesis functionalization of deboronated B‐MWW with Sn. These materials are highly active, selective, and recyclable catalysts for the conversion of triose sugars to methyl lactate (in methanol) and lactic acid (in water). They also demonstrate good performance in the conversion of hexose sugars and sucrose to methyl lactate.
