| titleOfInvention | Polyester manufacturing method |
| abstract | [PROBLEMS] To reduce the quality of a polyester obtained by an economical method in a process for continuously producing polyester by performing an esterification reaction in the presence of a phosphorus compound and using a single esterification reaction tank. To provide a method capable of recovering and recycling the glycol distilled in the production process of the polyester without causing it to flow. In a method for producing a polyester in the presence of a phosphorus compound, a glycol produced by distillation from a production process is fractionated by distillation and reused, and the following requirements are satisfied simultaneously: . (1) Adding a phosphorus compound to the transfer line of the esterification reaction product from the esterification reaction tank to the polycondensation reaction tank. (2) Distillation with the distillate from the esterification reaction tank and polycondensation. Separate and process the distillate from the reaction tank [Selection figure] None |
