Synthesis of Dimethyl Carbonate via Transesterification on Heterogeneous Catalyst in Catalytic Distillation

In a catalytic distillation apparatus,dimethyl carbonate was synthesized from methanol and propylene carbonate(PC) catalyzed by solid base.Catalyst activity of different carriers loaded with calcium oxide were compared.Using bakelite supported calcium oxide as catalyst,PC conversion reached 97.43% at 337 K and LHSV 0.3 h~(-1) with reflux ratio of 6/1.
