How substituent effects influence the thermodynamics and kinetics of gas-phase transesterification of alkyl lactates to lactide using TiO2/SiO2

open access: yesApplied Catalysis B: Environmental, 2022
Lactide, a crucial precursor of the bioplastic polylactic acid, was obtained through the gas-phase transesterification of alkyl lactates using a 5 wt% TiO2/SiO2 catalyst as an alternative to the conventional liquid-phase process.

Comparative study on morphological, rheological and functional characteristics of extruded rice starch citrates and lactates

International Journal of Biological Macromolecules, 2021
Two levels of chemically modified starches (starch citrates and lactates) prepared at 20% and 40% w/v concentration was subjected to extrusion to produce pregelatinized starches (PG).

CSF lactate

Practical Neurology, 2020
Lactate is produced from anaerobic glycolysis, which occurs in most tissues in the human body. Blood lactate is tested in most physiologically unwell patients in the Emergency Department and helps to guide treatment and prognosis. Cerebrospinal fluid (CSF) lactate, however, is not often measured.

Comparative study of gas-phase “dehydration” of alkyl lactates and lactic acid for acrylic acid production over hydroxyapatite catalysts

, 2020
Gas-phase “dehydration” of methyl (ML) and ethyl lactates (EL) for acrylic acid (AA) production was studied and compared with the dehydration of lactic acid (LA) over serial hydroxyapatite catalysts of varying compositions (HAPm-360, molar Ca/P ratio m =
