実験手順
An autoclave equipped with a stirrer and distillation outlet was charged with 166 g (1.00 mole) of terephthalic acid, 180 g (2.00 moles) of 1,4-butanediol, and a small amount of lithium acetate as a catalyst. After the autoclave was provided with nitrogen at 3 kg/cm2, the mixture was reacted at 260° C. for 3 hours to obtain BHBT.
