| titleOfInvention | Method for producing aromatic carbonates |
| abstract | An object of the invention is to provide a method for continuously producing aromatic carbonates at high energy efficiency, not requiring any complicated step. The method for producing aromatic carbonates which is characterized in that, in the method for producing alkylaryl carbonates and/or diaryl carbonates, comprises reacting a dialkyl carbonate with an aromatic hydroxy compound in the presence of a catalyst, the transesterification is effected in a reaction apparatus having a structure of at least two independent reaction zones connected in series, in such a controlled manner that a liquid phase is led into the first reaction zone to the final reaction zone in order, and the heat of condensation of the vapor generated in at least one reaction zone is transferred to a liquid fed into that reaction zone or into the reaction zone of the previous stage to heat it, and the vapor is kept away from direct contact with the intended reaction liquid. |
