    摘要： It is an object of the present invention to provide a specific industrial separation process that enables an alcohol to be separated out efficiently and stably for a prolonged period of time from a large amount of a low boiling point reaction mixture containing a by-produced alcohol when mass-producing aromatic carbonates on an industrial scale by subjecting a dialkyl carbonate and an aromatic monohydroxy compound to transesterification reaction in a reactive distillation column in which a catalyst is present. Although there have been various proposals regarding processes for the production of aromatic carbonates by means of a reactive distillation method, these have all been on a small scale and short operating time laboratory level, and there have been no disclosures whatsoever on a specific process or apparatus enabling mass production on an industrial scale to be carried out stably for a prolonged period of time. Moreover, there have been no disclosures on a specific process or apparatus enabling the alcohol by-produced when producing aromatic carbonates the an industrial scale using a reactive distillation system to be separated out efficiently and stably for a prolonged period of time on an industrial scale of not less than 200 kg/hr. According to the present invention, there is proposed a specific process using a continuous multi-stage distillation column having a specified structure enabling the above object to be attained.

    摘要： It is an object of the present invention to provide a specific process that enables a high-purity diphenyl 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 a phenol. When producing, from a cyclic carbonate and a phenol, a high-purity diphenyl carbonate required for producing a high-quality high-performance aromatic polycarbonate, the above object can be attained by carrying out a process according to the present invention which comprises steps of: (I) producing a dialkyl carbonate and a diol using a reactive distillation column having a specified structure; (II) producing a diphenyl carbonate using two reactive distillation columns each having a specified structure, and (III) obtaining a high-purity diphenyl carbonate from the diphenyl carbonate using a high boiling point material separating column A and a diphenyl carbonate purifying column B.
