| Research Abstract |
The corrmiercial production of glycerol has increased considerably for several years, because of its rising inevitable formation as a by-product ofbiodiesel production. For the effective utilisation of glycerol, a new synthesis of glycerol carbonate(4-hydroxymethyl-2-oxo-1,3-dioxolane)which is used as raw material of polycarbonate ffom glycerol was explored. By combined sulfUr-assisted carbonylation of glycerol under 1.0 MPa of carbon monoxide at 80℃ in DMF with oxidation by copper(II)bromide, a facile synthetic method for glycerol carbonate in good yield was developed. Also, by the selenium-catalyzed carbonylation of slightly excess of glycerol with carbon monoxide and potassium carbonate under 0.1 MPa at 20℃ in DMF, followed by the oxidation with molecular oxygen(0.1MPa,20℃), glycerol carbonate was obtained in good yields. The catalytic synthesis of glycerol carbonate was also brought about in the mixed gas atmosphere (carbon monoxide:oxygen=3:1,0.1 Mpa,20℃).
