摘要:在苄基三乙基氯化铵-乙二醇共催化作用下,以萜烯基环氧树脂为原料,与CO2在无溶剂环境中反应合成了萜烯基环碳酸酯。研究了催化剂用量、CO2压力、反应温度以及反应时间对反应过程的影响,并采用电位滴定法测定了产物中环碳酸酯的含量。研究表明,在催化剂用量1.0%、CO2压力1.0 MPa条件下,130℃反应7 h,生成产物的环碳酸酯值为0.267,环氧基转化率达99.7%,环碳酸酯选择性达到94.0%。同时,采用凝胶渗透色谱(GPC)、红外光谱(FT-IR)、质谱(MS)、核磁共振氢谱(1H NMR)及碳谱(13C NMR)表征了合成产物的化学结构。
A novel biomass terpene-based cyclic carbonate (TCC) was prepared by treatment of terpene-based epoxy resin (TME) with carbon dioxide in the conjunctional catalysis of triethylbenzylammonium and ethylene glycol without arty organic sol- vent. The effects of catalyst dosage, carbon dioxide pressure, reaction temperature and time on the reaction were investigated. The cyclocarbonate value of the product was obtained by the method of potentiometric titration. The results showed that the cyclo- car bonate value of the product was 0. 267, the conversion of terpene-based epoxy resin and the selectivity tbr cyclic earbonate were as high as 99.7 % and 94.0 % under optimum conditions ( catalyst concentration 1. 0 %, CO2 pressure 1.0 MPa, reaction temperature 130 ℃and reaction time 7 h), respectively. The chemical structure of the novel terpene-based cyclic carbonate was characterized by GPC, FT-IR, MS, 1H NMR and 13C NMR.
