摘　　要：以正辛醇和环氧氯丙烷为原料,在四丁基溴化铵作相转移催化剂条件下,合成了正辛基缩水甘油醚。根据正交实验设计确定了最佳反应条件,通过红外光谱表征了产物的结构,并依据气相色谱流出曲线计算了产物的纯度。实验结果表明:n(辛醇):n(环氧氯丙烷)=1:1.4、反应温度为40～50℃、反应时间为4～5h、ω(碱)约为50%时,产物的产率最高,可达91.6%,纯度可达87%以上。Octyl glycidyl ether was prepared by the reaction of n-octyl alcohol with epichlorohydrin in the presence of tetrabutyl ammonium bromide as phase-transfer catalyst. According to the orthogonal experimental design, optimal reaction conditions were determined. The structure of the product was characterized by infrared spectroscopy while the purity was calculated according to elution profile of gas chromatogram. The results showed that when n（octyl alcohol） ： n（epichlorohydrin） was 1 ： 1.4,the reaction temperature was 40-50℃ ,the reaction time was 4-5h,the w（alkali）was about 50% ,the product got highest yield up to 91.6% and the purity was above 87%.
