Abstract

The invention discloses a preparation method of tributyltetradecylphosphonium chloride, which comprises the following steps: dissolving tributylphosphine and alkyl halide used as raw materials in a mixed solvent composed of an organic solvent and water, adding an organic water-soluble free radical initiator under heating and pressurizing conditions, and conducting reacting to generate tributyltetradecylphosphonium chloride, wherein the mixed solvent is composed of N,N-dimethylformamide and water according to a volume ratio of (1-3):1, the molar ratio of tributylphosphine to alkyl halide is (0.5-1.5):1, and 1mmol of tributylphosphine is dissolved in 3-5ml of the solvent. A traditional organic solvent is improved into a mixed solvent of the organic solvent and an aqueous solution, the dosageand toxicity of the organic solvent are reduced to a certain extent on the basis that the original reaction efficiency, yield and production cost are guaranteed, and safety protection and sustainabledevelopment of the production environment are facilitated.

Description

technical field [0001] The invention belongs to the technical field of chemical production, and in particular relates to a preparation method of tributyltetradecylphosphonium chloride. Background technique [0002] Tributyltetradecylphosphonium chloride, also known as tributyltetradecylphosphonium chloride (TPCC), is a chemical substance with the molecular formula C 26 h 56 ClP. [0003] The usual methods for preparing tributyltetradecylphosphonium chloride in the prior art have the problem of low efficiency and poor environmental protection, so further improvement is required. Contents of the invention [0004] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a method for preparing tributyltetradecylphosphonium chloride, which reduces the amount and toxicity of organic solvents, and is conducive to the safety protection and reliability of the production environment. Continuous development. [0005] Techni...
