【摘要】 由对苯二酚与二氯甘醇反应合成了一系列聚多缩乙二醇对苯二酚醚,M=2800～4500。这些聚醚是一类高效、广谱性气相色谱固定液,可用于有机混合物的有效分离鉴定。更多还原

【Abstract】 The oligomeric ethylene glycol di-p-hydroxyphenyl ethers have been synthesized by Wil-liamson reaction of p-hydroxybenzene with dichloroethane, dichloroethylether, dichlorotrig-lycol dichlorotetraglycol and characterized by IR, UV, ¹H NMR, ¹³C NMR. The oligomerscan be used as stationary phases in gas chromatography for separation of mixed organiccompounds: alcohols, phenols, amines, esters, and aromatic hydrocarbons.更多还原
