The invention provides a preparation method of 2, 2-difluoroethanol. The preparation method comprises the steps as follows: when an organic solution is neutralized to the temperature of subzero 20 DEG C-0 DEG C, methyl difluoroacetate or ethyl difluoroacetate is taken as a raw material, lithium aluminum hydride is taken as a reducing agent, and high-yield and high-purity 2, 2-difluoroethanol is obtained. The method is simple and convenient and can be applicable to large-scale industrial production, and the raw material is easy to obtain.
