Catalytic transesterification of glycerol: Optimization for production of glycerol carbonate [PDF]
Malaysian Journal of Fundamental and Applied Sciences, 2019 The purpose of this research was to study the effect of reaction temperature, reaction time and dimethyl carbonate:glycerol (DMC:Gly) molar ratio on the conversion of glycerol and yield of glycerol carbonate. The reaction was further optimized with central composite design (CCD), 15 runs of transesterification reaction were conducted.

Superhydrophilic surfaces from short and medium chain solvo-surfactants
Oléagineux, Corps gras, Lipides, 2013 Pure monoglycerides (GM-Cs) and glycerol carbonate esters (GCE-Cs) are two families of oleochemical molecules composed of a polar part, glycerol for GM-Cs, glycerol carbonate for GCE-Cs, and a fatty acid lipophilic part. From a chemical point of view,

Enhanced conversion of Glycerol to Glycerol carbonate on modified Bio-Char from reed plant
Iraqi Journal of Chemical and Petroleum Engineering, 2019 The surplus glycerol produced from biodiesel production process as a by-product with high quantity can be considered as a good source to prepare glycerol carbonate (GC) whereas with each 1000 kg from biodiesel obtains 100 kg from glycerol.
