Abstract Hydroxyapatite (HAP) modified with different metal salts were prepared by wet-impregnation method and used as a catalyst for the synthesis of glycerol carbonate via transesterification from glycerol and dimethyl carbonate (DMC). It was found that KF/HAP was a highly efficient heterogeneous catalyst for the synthesis of glycerol carbonate and

Utilization of glycerol for the production of glycerol carbonate through greener route
Journal of Environmental Chemical Engineering, 2013Abstract Availability of glycerol is increased in recent years due to production of biodiesel. Glycerol carbonate, an important compound, can be manufactured using glycerol as a raw material. This work describes the synthesis of glycerol carbonate from glycerol via an enzymatic transesterification reaction using dimethyl carbonate as co-substrate and

Biosynthesis of glycerol carbonate from glycerol by lipase in dimethyl carbonate as the solvent
Bioprocess and Biosystems Engineering, 2010Glycerol carbonate was synthesized from renewable glycerol and dimethyl carbonate using lipase in solvent-free reaction system in which excess dimethyl carbonate played as the reaction medium. A variety of lipases have been tested for their abilities to catalyze transesterification reaction, and Candida antartica lipase B and Novozyme 435 exhibited ...

Electrosynthesis of Glycerol Carbonate from Glycerol and Potassium Carbonate on Nickel Electrodes
ECS Transactions, 2017The growing biodiesel industry leads to an excess production of glycerol by-product which is of low value but costly to store or dispose because glycerol is not suitable as fuel due to its sooty flame while its discharge to water leads to eutrophication.

Glycerol and glycerol carbonate as ultraviscous solvents for mixture analysis by NMR
Journal of Magnetic Resonance, 2011NMR of weakly polar analytes in an apolar ultraviscous solvent has recently been proposed for mixture analysis as a pertinent alternative to the DOSY experiment. The present article reports the first use of glycerol and glycerol carbonate as polar solvents for the NMR analysis of a model mixture of dipeptides.

Synthesis of glycerol carbonate from glycerol and dimethyl carbonate catalyzed by calcined silicates
Applied Catalysis A: General, 2017Abstract Several anhydrous silicates were prepared by calcination at 400 °C and utilized as solid base catalyst for synthesizing glycerol carbonate (GC) by transesterification of glycerol with dimethyl carbonate (DMC). Among them, calcined sodium silicate showed the best catalytic activity with glycerol conversion of 97.7%.

Glycerol carbonate synthesis from glycerol and dimethyl carbonate using trisodium phosphate
Journal of the Taiwan Institute of Chemical Engineers, 2016Abstract Glycerol, a major biodiesel byproduct, was valorized using anhydrous trisodium phosphate (TSP) as a reusable heterogeneous catalyst in glycerol carbonate (GC) synthesis. The reaction progressed via catalytic carboxylation pathway of glycerol with dimethyl carbonate (DMC) under various reaction conditions.
