METHOD OF MANUFACTURE OF HIGH-PURE DIPHENYL CARBONATE IN INDUSTRIAL SCALE |
| abstract |
The object of the present invention is to provide a specific method that makes it possible to produce high-purity diphenyl carbonate, which can be used as a raw material for high-quality, with excellent performance parameters of polycarbonate, stable for a long time on an industrial scale in an amount of not less than 1 ton / h from the reaction mixture containing the catalyst and reaction by-products, which is obtained by the transesterification reaction and the like. using dialkyl carbonate and phenol as starting material. According to the present invention, a high boiling point material separation column A and a diphenyl carbonate purification column B are provided, each including a continuous multi-stage distillation column having certain designs, and a certain method is provided that allows the production of high-purity diphenyl carbonate, which is important as a feedstock for high quality and excellent operating parameters of polycarbonate, stable for a long period of time on an industrial scale in an amount of not less than 1 ton / hr from the reaction mixture containing diphenyl carbonate using a plant in which these two continuous multistage distillation columns are connected together. |
