| 摘 要： | 以甲苯为溶剂,四氢糠醇、氢氧化钠、溴乙烷和顺丁烯二酸酐为原料,制备四氢糠醇乙醚。考察了原料配比、温度、时间等对收率和含量的影响,优化条件为n(四氢糠醇):n(氢氧化钠):n(溴乙烷)=1:1:1-1.2;n(再精制时残余四氢糠醇):n(顺丁烯二酸酐)=1∶1.2,在合成四氢糠醇钠盐时,反应温度115℃,反应时间4-5h;在反应脱除残余四氢糠醇时,反应温度60-70℃,反应时间6h,四氢糠醇乙醚总收率达75%,纯度99%。制备的四氢糠醇乙醚能满足阴离聚合合成高乙烯基含量的SSBR的要求。

| Abstract: | Toluene was used as a solvent for the reaction of tetrahydrofurfuryl alcohol（THFA）,sodium hydroxide,ethyl bromide with meleic anhydride.Ethyl tetrahydrofurfuryl ether（ETFE） was obtained in 75% yield with 99% purity under the optimum reaction conditions： n（THFA）∶n（sodium hydroxide）∶n（ethyl bromide）=1∶1∶1-2.n（residual THFA）∶n（meleic anhydride）=1∶1.2.Reaction temperature 115 ℃ and the reaction time4-5h wherein THFA was reacted with sodium hydroxide to produce an alkali alkoxylate salt;Reaction temperature 60-70 ℃ and the reaction time 6h wherein residual THFA was reacted with meleic anhydride to produce a high boliling point addition product.Synthetic ETFE was used as modified microstructure of high vinyl SSBR. |
