【Abstract】 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.更多还原
