乙二醇单烷基醚的合成及性能

Synthesis and Properties of Monoalkyl Ethers of Ethylene Glycol

以乙二醇和卤代烷为原料 ,用相转移催化法合成了 7种乙二醇单烷基醚 ,均获得较高产率 .讨论了乙二醇单烷基醚合成的反应历程 ,并对其物理常数、水溶液的表面张力、起泡性能、临界胶束浓度进行了测试和分析 .

Seven monoalkyl ethers of ethylene glycol were synthesised,which was obtained by the phase transfer catalyzed williamson ether reaction of alkyl halide and ethylene glycol and acquired high yield of pure monoethers.The reaction course and the physical constant were discussed.The properties of the surfactant,such as surface tension,foam as well as critical micellization concentration in aqueous solution were discussed.
