摘要
本文用氯乙酰氯(CAC)分别与乙二醇、一缩二乙二醇、二缩三乙二醇及六种不同分子量的聚乙二醇反应,合成了相应的酯类产物,测定了产物的折光率、表面张力等物理常数,用IR和~1H-NMR研究了产物的结构表征.并较详细地讨论了各种因素对CAC与聚乙二醇400的反应的影响.
Esters products were synthesised through the reactions of chloroacetyl chloride with ethy-lene glycol, diethylene glycol, triethylene glycoJ and six polyethylene glycols with different average molecular weights, respectively. Index of refraction, density and surface tension of liquid products were measured and structures of the products were characterized with IR and 2H-NMR spectroscopies. For the reaction between chloroacetyl chloride and polyethylene glycol (Mn= 400), influences of reaction conditions suchas feed ratio, temperature, time and environment have been investigated.
