More Information
Summary:The preparation method comprises the following steps: mixing fluoroolefin or fluoroalkene ether with alcohol or phenol, carrying out a catalytic reaction to obtain a crude product of the hydrofluoroether compound, carrying out reaction precipitation separation on a small amount of by-product alkene ether in the crude product of the hydrofluoroether compound, and carrying out distillation purification to obtain the high-purity hydrofluoroether compound. The addition reaction of alcohol and fluoroolefin is simple to operate and mild in reaction condition; ions, a high-boiling-point solvent and the like in the hydrofluoroether can be removed through distillation, a byproduct hydrofluoroether containing unsaturated bonds is obtained, and the distillation temperature can be selected to be higher than the boiling point of the generated hydrofluoroether and lower than the boiling point of the solvent; the method is high in efficiency, low in comprehensive cost, simple in treatment, non-toxic and more environment-fri
