| 摘 要： | 二-（2-羟乙基）醚（俗称二甘醇）在甲苯中与偏硼酸酐反应得到偏硼酸三-（2-羟乙氧基-1-基）乙酯，再经氯化亚砜处理得到偏硼酸三-（2-氯乙氧基-1-基）乙酯，最后水解得到目标产物2-（2-氯乙氧基）乙醇。该工艺原料易得、操作简便、条件温和。最后总收率（以二甘醇计）达到68．3％。

| Abstract: | Metaboric acid tri-2- （2-chloroethoxy）ethanate has been synthesized through chlorination with SOCl2 of Tri-2- （2-hydroxyethoxy）ethanate, which was obtained from diethylene glycol and metaboric anhydride using toluene as the solvent, with SOCl2. The product 2-（2-chloroethoxy）ethanol can be obtained from tri-2-（2-chloroethoxy）ethanate through hydrolyzation. Easily obtainment of the raw material, convenient operation and mild conditions have been observed in this method. The total yield（based on diethylene glycol） is 68.3%. |
