| titleOfInvention | Industrial separation of by-product alcohols |
| abstract | The problem to be solved by the present invention is to produce a large amount of aromatic carbonate on an industrial scale by subjecting a dialkyl carbonate and an aromatic monohydroxy compound to a transesterification reaction in a reactive distillation column in the presence of a catalyst. Specific industrial separation method capable of efficiently and stably separating alcohols for a long time from a large amount of low boiling point reaction mixture (1 ton / hr or more) having a specific composition containing alcohols by-produced as a by-product Is to provide. There are many proposals for the production of aromatic carbonates by reactive distillation, but these are all small-scale and short-term laboratory levels, enabling stable mass production on an industrial scale for a long time. There was no disclosure of a specific method or apparatus. A specific method for efficiently and stably separating alcohols produced as a by-product when producing aromatic carbonates on an industrial scale by reactive distillation on an industrial scale of 200 kg or more per hour There was no disclosure of devices. In the present invention, a continuous multi-stage distillation column having a specific structure and a large amount of a low boiling point reaction mixture (1 ton / hr or more) having a specific composition including by-produced alcohols can achieve this object. Is provided. |
