中文摘要：

为得到纯度较高的乙二醇二缩水甘油醚作为联接基，利用减压蒸馏切割馏分对其进行提纯，通过开环反应与壬基酚合成一种双子二醇中间体。考虑不同合成条件对双子二醇收率的影响。利用红外光谱和色质联用仪对联接基和双子二醇进行结构表征。结果表明：乙二醇二缩水甘油醚的沸点为116～119℃（666．6Pa），纯度为94．51％；当反应温度100℃、催化剂KOH0．25％与三苯基膦0．25％复配、反应时间3～5h时，双子二醇的产率达88．2％；化合物结构与所设计的分子结构相同。

英文摘要：

In order to obtain high-purity ethylene glycol diglycidyl ether（EGDGE） as spacer, the purification of EGDGE was completed using vacuum distillation to cut fraction. Then the dimer gemini-diol intermedium was synthesized by ring opening reaction. The effects of different conditions on gemini-diol yield were considered. The structures of the spacer EGDGE and gemini-diol were characterized by IR and chromatograph mass spectrometer. The results show that the EGDGE＇s boiling point is 116-119 % （666.6 Pa） and purity is 94.51%. The optimum reaction conditions are that reaction temperature is 100℃, the catalyst is the compound of KOH and phosphorus triphenyl whose mass fraction is 0.25%, and reaction time is 3-5 h. The ultimate yield of gemini-diol is 88.2%. The molecular structure of the sample is the same as that of the designed.
