【Abstract】 Three novel hydrofluoroethers were prepared by reacting 2,2,3,3-tetrafluoro-1-propanol with alkyl halides in diethylene glycol dimethyl ether. The appropriate condition was found out by means of orthogonal test. The prepared ethers were characterized by IR, MS. Their boiling point, density, surface tension and viscosity were determined. Furthermore, the degreasing ability of the HFEs was tested. The result shows they are good solvents for grease.更多还原
