Abstract

PURPOSE: After esterinterchange reaction between terephthalic acid and 1,4-butanediol is effected to the level of prescribed exchange rate, polycondensation reaction is advanced, thereby preventing the formation of tetrahydrofuran and facilitating the handling of 1,4-butanediol during winter.
CONSTITUTION: Esterinterchange reaction between lower alkyl esters of difunctional carboxylic acids mainly consisting of terephthalic acid and glycols mainly consisting of 1,4-butanediol is effected and then the polycondensation reaction of the resulting product is continued to form polyester wherein the esterinterchanging reaction is effected at 120W190°C unitl the rate of esterinterchange reaches 70W90%. The glycols distilled under reduced pressures ontains alkanols; however, it can be directly reused without purification as the raw material for polyester.
