Preparation method of dialkylphosphinic acid

The invention discloses a preparation method of dialkylphosphinic acid, which comprises the following steps: adding phosphorous acid into a reaction kettle, adding a catalyst, and carrying out pyrolysis at 170-190 DEG C to generate hydrogen phosphide; introducing the obtained hydrogen phosphide into a reaction kettle containing olefin, conducting heating and pressurizing in the presence of an initiator, and conducting reacting to obtain dialkylphosphine; and adding the obtained dialkylphosphine into a solvent, adding hydrogen peroxide while stirring, and conducting reacting to obtain the dialkylphosphinic acid. According to the preparation method of the dialkylphosphinic acid, high-purity phosphide hydrogen raw material gas is prepared by pyrolyzing phosphorous acid, free radical additionreaction is conducted on the phosphide hydrogen raw material gas and various olefins to prepare high-purity, high-grade and high-added-value dialkylphosphine, and subsequent controllable oxidation isconducted by taking the dialkylphosphine as a raw material to obtain the dialkylphosphinic acid. Various types of dialkylphosphinic acids are prepared, the operation steps are simple, and the operation conditions are mild.
