| titleOfInvention | Method for producing polyester resin |
| abstract | (57) [Problem] To provide a polyester resin containing, as a main repeating unit, a foreign substance which does not melt at the melting point of polybutylene terephthalate resin generated in a reaction tank, particularly, butylene terephthalate having a small amount of black foreign substances such as scale and carbide. To be manufactured with high productivity. A method for producing a polyester resin containing butylene terephthalate as a main repeating unit from an acid component containing terephthalic acid or a lower alkyl ester thereof as a main component and a diol component containing 1,4-butanediol as a main component. The temperature of the heat retaining control of the inner wall surface of the vacuum distillation pipe installed on the upper part of the reaction tank for performing the polycondensation reaction and / or the inner wall surface of the reaction tank in contact with the gas phase in the reaction tank. A method for producing a polyester resin containing butylene terephthalate as a main repeating unit, which is subjected to a polycondensation reaction at a temperature of 60 ° C. or lower. |
