摘要: 以环氧橡胶籽油(ERSO)为原料,甲醇和异丙醇为开环试剂,氟硼酸为催化剂,制备橡胶籽油基多元醇,以产物羟值为指标对制备工艺进行了优化,并对产物进行了表征。研究结果表明,橡胶籽油基多元醇的最佳制备条件为反应时间30min,反应温度70℃,醇与ERSO的质量比为4:1,氟硼酸用量为ERSO质量的1%,异丙醇与甲醇质量比为1:1。通过验证实验可知,在此条件下制备的橡胶籽油基多元醇酸值为2.68mg/g,羟值为219.32mg/g,平均相对分子质量为870.21,含水量为0.08%,黏度为4791mPa·s。同时,通过FT-IR、1H NMR和13C NMR分析表征了橡胶籽油基多元醇的化学结构,结果表明,ERSO中的环氧基发生了开环反应,生成了多元醇。

Abstract: Rubber seed oil based polyol was prepared by using epoxidized rubber seed oil(ERSO) as raw materials,methanol and isopropanol as ring-opening reagents,and fluoboric acid as catalyst,the preparation conditions were investigated with the hydroxyl value of product as index,and the characterization of product was also studied. The results showed that the optimum reaction conditions were reaction time 30min,reaction temperature 70℃,the mass ratio of to alcohol to ERSO 4:1,the amount of fluoboric acid 1%(based on the mass of ERSO),the mass ratio of isopropanol to methanol 1:1. The results of verification experiment showed that the acid value,hydroxyl value,average molecular weight,moisture content and viscosity of rubber seed oil based polyol prepared under the optimum reaction conditions were 2.68mg/g,219.32mg/g,870.21,0.08% and 4791mPa·s,respectively. Furthermore,the chemical structure of rubber seed oil based polyol was characterized by FT-IR,1H NMR and 13C NMR,the results showed that the polyol was formed by the ring-opening reaction of epoxy group of ERSO.

Key words: rubber seed oil based polyol, epoxidation-hydroxylation method, epoxidized rubber seed oil
