A facile synthesis of glycerol carbonate by transesterification of glycerol with dimethyl carbonate: Ceria based catalysts

Journal of the Mexican Chemical Society, 2019
Abstract. Solid base catalysts such as Ceria-Zirconia-Magnesia with different mole ratio of magnesium were prepared by impregnation method and characterized by CO2-TPD, PXRD, FT-IR and ICP-OES analysis. The catalytic activity of the catalysts was tested in the liquid phase transesterification of glycerol with dimethyl carbonate to synthesise glycerol ...

Glycerol Carbonate Production via Transesterification: The Effect of Support Porosity and Catalyst Basicity

Processes
Glycerol transesterification with diethyl carbonate (DEC) using catalysts with different porosities as support for CaO was performed, seeking the evaluation of how textural properties influence glycerol conversion and product selectivity.

Glycerol carbonate synthesis via Zn(OBu)2/AlCl2(OBu) initiated-glycerolysis of urea

Chemistry of Inorganic Materials
Glycerol carbonate (4-hydroxymethyl-1,3-dioxolane-2-one) was efficiently synthesized from glycerolysis of urea initiated by Zn(OBu)2/Al(OBu)Cl2. The zinc-aluminum complex mixture was prepared from zinc chloride (ZnCl2) and aluminum tri-sec-butylate (Al ...

Application of pervaporation in the bio-production of glycerol carbonate

, 2018
Glycerol carbonate is a platform molecule with a large range of applications. It can be synthesized from glycerol by transesterification with dimethyl carbonate, which is considered a bio-based path of synthesis since glycerol is originated during the ...

Boiler Ash-Catalysed Synthesis of Glycerol Carbonate from Glycerol [PDF]

, 2013
Over the years production of glycerol as a crude waste from biodiesel making industries has been largely increasing. This is because for every 100 kg of biodiesel produced 10 kg of glycerol is produced as a by-product which corresponds to 10 weight ...
