METHOD FOR CONTINUOUSLY PRODUCING AROMATIC CARBONATE AND REACTION DEVICE FOR THE METHOD

摘要

PURPOSE: Provided are a method for continuously and economically producing an aromatic carbonate, which is suitable for commercial production, and a reaction device for the method. CONSTITUTION: The method for continuously producing an aromatic carbonate by using a heterogeneous catalyst, comprises the steps of (i) injecting a dialkyl carbonate or alkyl aryl carbonate and an aromatic hydroxy compound into the reactor(1) injected with a heterogeneous catalyst; (ii) filtrating the reaction liquid obtained in the step(i) to isolate the heterogeneous catalyst; (iii) cycling the filtrated reaction liquid while applying the heat from the outside of the reactor; (iv) distilling a reaction byproduct vaporized with the heat of the step(iii) and ingredients with low boiling point, and condensing effective ingredients having relatively high boiling point to recover the reactor; and (v) extracting the high boiling ingredients which are final reactants, from the reaction liquid at intermediate time of the cycling step.
