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