Catalytic Performance of Li/Mg Composites for the Synthesis of Glycerol Carbonate from Glycerol and Dimethyl Carbonate [PDF]

open access: yesACS Omega, 2022
A series of Li/Mg composites were synthesized by the coprecipitation method using magnesium and lithium nitrates, and then used for the synthesis of glycerol carbonate (GC) from glycerol and dimethyl carbonate (DMC). The experimental results indicated that Li/Mg composites were prospective catalysts for GC synthesis.

Synthesis of Glycerol Carbonate from Ethylene Carbonate Using Zinc Stearate as a Catalyst: Operating Conditions and Kinetic Modeling [PDF]

open access: yesMolecules, 2023
With the advent of biodiesel as a substitute/additive for diesel, the production of glycerol has experienced an increase, as it is an unavoidable byproduct of the biodiesel process; therefore, novel products and processes based on this triol are being ...

Transesterification of Glycerol with Dimethyl Carbonate to Glycerol Carbonate over Na–based Zeolites [PDF]

open access: yesChinese Journal of Catalysis, 2012
Abstract Glycerol carbonate (GC) was synthesized via transesterification of glycerol with dimethyl carbonate under mild conditions over a series of base zeolites. It was found that the NaY zeolite exhibited a higher selectivity for GC (100%) than heterogeneous bases (such as CaO and SrO) or homogeneous catalysts (such as NaOH and K2CO3).

The Synthesis of Glycerol Carbonate from Glycerol and Carbon Dioxide over Supported CuO-Based Nanoparticle Catalyst. [PDF]

open access: yesMolecules, 2023
A series of supported CuO-based nanoparticle catalysts were prepared by impregnation method and used for the synthesis of glycerol carbonate from glycerol and CO2 in the presence of 2-cyanopyridine as a dehydrant and DMF as a solvent. The effects of supports (activated alumina, silicon dioxide, graphene oxide, graphene, and activated carbon), CuO ...

Ultrasound assisted enzyme catalyzed synthesis of glycerol carbonate from glycerol and dimethyl carbonate

open access: yesUltrasonics Sonochemistry, 2015
The present work illustrates the transesterification of glycerol to glycerol carbonate (GlyC) from dimethyl carbonate (DMC) using commercial immobilized lipase (Novozym 435) under ultrasonic irradiation. The experiments were performed in a batch reactor placed in an ultrasonic water bath using a sequence of experimental protocol to evaluate the effects
