Industrial process for production of high-purity diaryl carbonates |
| abstract |
It is an object of the present invention to provide a specific process that enables a high-purity diaryl carbonate required for producing a high-quality high-performance aromatic polycarbonate to be produced industrially in a large amount (e.g. not less than 1 ton / hr) stably for a prolonged period of time (e.g. not less than 1000 hours, preferably not less than 3000 hours, more preferably not less than 5000 hours) from a cyclic carbonate and an aromatic monohydroxy compound. When producing a high-purity diaryl carbonate from a cyclic carbonate and an aromatic monohydroxy compound, the above object can be attained by carrying out a process of the present invention which comprises the steps of: (I) producing a dialkyl carbonate and a diol using a reactive distillation column having a specified structure; (II) producing a diaryl carbonate using two reactive distillation columns each having a specified structure; and (III) purifying the diaryl carbonate so as to obtain a high-purity diaryl carbonate. |
