| titleOfInvention | INDUSTRIAL METHOD OF MANUFACTURE OF AROMATIC CARBONATE |
| abstract | An object of the present invention is to provide a specific process for the continuous production of aromatic carbonates containing a diaryl carbonate as a main product by using as a starting material an alkyl aryl carbonate which can be obtained by a transesterification reaction between a dialkyl carbonate and an aromatic monohydroxy compound using a continuous multi-stage distillation column in which a catalyst is present, and a continuous feed of the starting material into a continuous multi-stage distillation column, which makes it possible to obtain diaryl carbonate with high selectivity and high productivity, stably for a long time on an industrial scale of at least 1 t / h. Although many different proposals have been made regarding processes for the production of aromatic carbonates by reactive distillation, they are all small-scale processes operating within a short period of time at the laboratory level, and there was no knowledge of any particular process or apparatus. providing the possibility of mass production on an industrial scale. According to the present invention, a specific continuous multi-stage distillation column is provided, and a specific process is provided, which makes it possible to obtain diaryl carbonate with high selectivity and high productivity stably for a long time on an industrial scale, of the order of not less than 1 t / h, from alkyl |
