Abstract

用Ti(OBu)4/TiO2-Al2O3催化剂合成了聚(己二酸-1,4-丁二醇)酯。Ti(OBu)4/TiO2-Al2O3合成聚(己二酸-1,4-丁二醇)酯的最佳反应条件:催化剂载体焙烧温度为750℃,焙烧时间为4 h,催化剂加入量为1.5%,n(己二酸)/n(1,4-丁二醇)=1∶(1.2~1.3),反应温度为165~170℃,反应时间4 h,在此条件下得到聚酯,酯化率为93.02%,Mn=3 080,Mn/Mw=1.206,催化剂可反复使用5次。

Other Abstract

Poly(adipic acid-1,4-butanediyl)ester was synthesized by Ti(OBu)_4/ TiO_2-Al_2O_3 as catalyst.The optimum condition are as follows:roasting temperature of catalyst carrier 750 ℃,roasting time 4 h,dosage of catalyst is 1.5%,n(adipic acid)/n(1,4-butanediol) is 1 ∶(1.2~1.3),under 165~170 ℃,reaction time is 4 h,the esterification rate is 93.02%,Mn=3 080,Mn/Mw=1.206,the catalyst could be used for 5 times.
