Integrated and Metal Free Synthesis of Dimethyl Carbonate and Glycidol from Glycerol Derived 1,3-Dichloro-2-propanol via CO2 Capture

Dimethyl carbonate (DMC) and glycidol are considered industrially important chemical entities there is a great benefit if these moieties can be synthesized from biomass-derived feedstocks such as glycerol or its derivatives. In this report, both DMC were in an integrated process derived 1,3-dichloro-2-propanol CO2 through metal-free reaction approach at mild conditions. Initially, the chlorinated cyclic carbonate, i.e., 3-chloro-1,2-propylenecarbonate was using equivalent interaction of organic superbase 1,8-diazabicyclo [5.4.0] undec-7-ene (DBU) with room temperature. Further, by base-catalyzed transesterification DBU methanol. The synthesis performed different solvents dimethyl sulfoxide (DMSO) 2-methyltetrahydrofuran (2-Me-THF). case, 2-Me-THF further facilitated easy separation product where 97% recovery obtained compared to 63% DMSO. use base transformation facilitates conversion 3-chloro-1,2 propandiol that forms situ during process. Hence, synthetic approach, not only eased capture served catalyst process, but it also reservoir for chloride ions, which overall components proceeded solvent extraction technique 93 89% glycidol, respectively, obtained. recovered salt, [DBUH][Cl], via neutralization technique. progress reactions well purity species confirmed means NMR analysis single base, renewable comprising carried out under conditions sequestration along chemicals synthesized.
