Description
本発明者らは、上記課題を解決するため、鋭意検討した結果、スルホ安息香酸化合物の金属塩を塩素化し、酸性水で金属塩化物を溶解した後、分液除去することにより、ろ過の必要が無く、また、加水分解が起こりにくく、クロロスルホニルベンゾイルクロライド化合物を収率よく取得できることを見出し、本発明を完成するに至った。 As a result of intensive investigations to solve the above problems, the present inventors have chlorinated the metal salt of the sulfobenzoic acid compound, dissolved the metal chloride with acidic water, and then separated and removed, thereby removing the filtration. The present inventors have found that the chlorosulfonylbenzoyl chloride compound can be obtained with good yield because it is not necessary and hydrolysis hardly occurs, and the present invention has been completed.
項２．酸性水が、塩酸水または硫酸水である、項１に記載のクロロスルホニルベンゾイルクロライド化合物の製造方法。 Item 2. Item 2. The method for producing a chlorosulfonylbenzoyl chloride compound according to Item 1, wherein the acidic water is hydrochloric acid water or sulfuric acid water.
前記塩素化反応に用いられる溶媒は、当該反応に対して不活性な溶媒であれば特に限定されず、例えば、ベンゼン、トルエン、クロロベンゼンおよびキシレン等の非水溶性有機溶媒を挙げることができる。 The solvent used for the chlorination reaction is not particularly limited as long as it is an inert solvent for the reaction, and examples thereof include water-insoluble organic solvents such as benzene, toluene, chlorobenzene and xylene.
