摘要：
The glycerin is transformed into glycerol carbonate by reaction with urea in the presence of a series of heterogeneous catalyst system including metallic sulfates or zinc organomettallic sulfate. Zinc sulfate exhibits characteristic catalytic behaviour in the carbonylation of glycerin into glycerol carbonate wich gives a good molar yield of 86% at 140degreesC, 30 mbar for 2 hours.
