Reactive distillation for synthesis of glycerol carbonate via glycerolysis of urea

This study developed a new process for synthesis of glycerol carbonate via glycerolysis of urea by reactive distillation. Missing thermodynamic parameters were estimated by various group contribution methods. The results of Gibbs free energy showed that Gani's method provided the lowest deviati...
