| titleOfInvention | Reaction system and method for producing high molecular weight polyester by continuous melt polycondensation |
| abstract | The invention aims to provide a reaction system and a method for producing high molecular weight polyester by continuous melt polycondensation, which are different from the traditional two-step method, and the invention synthesizes the high molecular weight polyester by a one-step method, thereby realizing high-purity reaction of esterification reaction and solving the defects of low reaction efficiency and low reactant conversion rate of the traditional reactor; in order to achieve the aim, the invention provides a reaction system and a method for producing high molecular weight polyester by continuous melt polycondensation, the invention provides a novel reaction system and a method for producing high molecular weight polyester by continuous melt polycondensation, which embody product differentiation, production line flexibility, on-line monitoring technology, and integration of environmental protection and energy saving technology, and greatly promote the development of the industry; the reaction system provided by the invention comprises: an esterification reactor, a pre-polycondensation reactor and a final polycondensation reactor; the esterification reactor, the pre-polycondensation reactor and the final polycondensation reaction kettle are connected in sequence through pipelines. |
