SYNTHESIS OF DEUTERATED DIMETHYL CARBONATE

Synthesis of Dimethyl Carbonate from Urea and Methanol

There is a great concern on the utilisation of CO2 due to its increased atmospheric concentration by anthropological emissions in the last few decades. Therefore, the fixation of inexpensive and abundantly available CO2 in valuable chemicals is gaining lot of interest in recent times. Despite this, there are only a few industrial processes where CO2 is consumed directly. One such process is the...

Synthesis of glycerol carbonate from glycerol and dimethyl carbonate in basic ionic liquids*

Glycerol carbonate is a key multifunctional compound used as solvent, additive, and building block in alternative chlorine-free processes. Here, we report the synthesis of glycerol carbonate from renewable materials (glycerol and dimethyl carbonate, DMC) using basic ionic liquids (ILs) as catalysts. After process optimization, it has been possible to isolate pure glycerol carbonate in quantitat...

Preparation of Solid Superacid SO42-/ZnO-TiO2 and Its Action on Synthesis of Dimethyl Carbonate from Urea and Methanol

SO42-/ZnO-TiO2 catalyst was prepared by sulfating ZnO-TiO2 powders with H2SO4 solution. The catalyst was characterized by XRD, IR and Hammett indicator. The catalyst showed strong acidity(H0 ≦-16.0). The optimum conditions are found that the calcination temperature is 823K and the so...

New developments in dimethyl carbonate chemistry*

Dimethylcarbonate (DMC) is a valuable methylating reagent which can replace methyl halides and dimethylsulfate in the methylation of a variety of nucleophiles. It couples tunable reactivity and unprecedented selectivity toward mono-Cand mono-N-methylation in the reactions of acidic CH2 and primary aromatic amines, respectively. In addition, it is a prototype example of a green reagent, since it...
