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℃(666.6 Pa),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3～5 h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。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.
