Lipase-catalyzed oligomerization and hydrolysis of alkyl lactates: direct evidence in the catalysis mechanism that enantioselection is governed by a deacylation step.

Biomacromolecules, 2010
Lipase-catalyzed oligomerization of alkyl d- and l-lactate monomers (RDLa and RLLa, respectively) was studied for the first time. It has been found that the oligomerization occurs enantioselectively only for d-lactates to give oligomers up to heptamers ...

Selective conversion of trioses to lactates over Lewis acid heterogeneous catalysts

Green Chemistry, 2011
Substituted mesoporous MCM-41 materials and transition-metal-free oxides were prepared and tested as heterogeneous catalysts for the direct conversion of trioses to lactates.

Zeolite-catalysed conversion of C3 sugars to alkyl lactates

Green Chemistry, 2010
The direct conversion of C3 sugars (or trioses) to alkyl lactates was achieved using zeolite catalysts. This reaction represents a key step towards the efficient conversion of bio-glycerol or formaldehyde to added-value chemicals such as lactate ...

Tin-catalyzed conversion of trioses to alkyl lactates in alcohol solution.

Chemical Communications, 2005
Tin chlorides, SnCl2 and SnCl4.5H2O are excellent catalysts for the reactions of trioses, dihydroxyacetone and glyceraldehyde with alcohols (MeOH, EtOH and nBuOH) to give alkyl lactates, whose reaction mechanism involves the intermediary formation of ...

Use of alcoholic–alkaline treated starch citrates and lactates as fat and protein replacer in imitation Mozzarella cheese

Journal of food process engineering, 2019
The present study substituted (a) casein (CR) and (b) casein and fat (CR + FR) simultaneously with cold water‐soluble (CWS) rice starch citrates and lactates to control functional characteristics of imitation cheese (IC).
