Reaction of Carbon Dioxide or Urea with Glycerol

Reaction of Carbon Dioxide or Urea with Glycerol 

Glycerol carbonate can be produced by reacting glycerol with phosgene, or with  

Glycerol does not react with C02 (Equation 7.25) in the presence of zeolites as catalyst [240], whereas Sn-catalysts [n-Bu2Sn(OMe)2, -Bu2SnO, Sn(OMe)2] promote the carboxylation of glycerol [241] at 5 MPa and 450 K. 

The most active among the catalysts tested was n-Bu2Sn(OMe)2 the results obtained under different reaction conditions are listed in Table 7.3. 

The glycerolysis of urea represents an alternative synthetic approach for the synthesis of glycerol carbonate (Equation 7.26)
