Research on Liquid Phase Synthesis of Tetrahydrofuran from 1,4-butanediol in the Production of Polybutylene Terephthalate
In recent years,traditional PBT devices face increasingly fierce competition and operational difficulties due to external environmental influences.This article analyzes the current situation of the PBT device,uses the existing tetrahydrofuran recovery device,and through experiments,explores the feasibility of liquid-phase synthesis of tetrahydrofuran from 1,4-butanediol in PBT production.The process is optimized,and industrial production is achieved through technological transformation,turning waste into treasure,improving the utilization rate of the device,enhancing the added value of the product,and achieving good economic benefits.
