The method uses triphenylphosphine, halogenated benzene and phenol as raw materials, and the sodium hydroxide solution is an acid binding agent. The preparation method comprises the following steps: triphenylphosphine. The halogenated benzene and the reaction solvent are mixed in a continuous flow reactor to prepare a tetraphenylhalogenated phosphine solution, a prepared tetraphenylhalogenated phosphine solution, phenol and sodium hydroxide solution with a concentration 32% are mixed in a continuous flow reactor to prepare a tetraphenylphosphine phenol salt. Compared with a conventional stirred tank reactor, the reactor used in the preparation method is smaller in size, simple to operate, continuous in reaction, high in yield, environmentally friendly, stable in pH value during reaction, relatively mild in reaction conditions and stable in prepared tetraphenylphenol salt.
