chlorosulfonation of acetanilide mechanism

PDF	204-210 Research Article Chlorosulfonation of Acetanilide to Obtain The third step was recrystallization of sulfathiazole to obtain purer product All the identification of samples was done using IR Spectroscopy with FT-IR [4]

What is the chlorosulfonation reaction?
Chlorosulfonation is introducing the chlorosulfonyl (- SO into organic molecule ₂Cl sulfonic acid chloride (R-SO) is formed ₂Cl mistake) Journey.It is a kind of substitution reaction, and a hydrogen atom in reactant is changed into chlorosulfonyl after the reaction.
Which chlorosulfonation of acetanilide to obtain an intermediate for the preparation of a sulfa drug?
Materials and Methods: Sulfathiazole is prepared by chlorosulfonation of acetanilide (at 114°C) to obtain an intermediate which is reacted with 2-aminothiazole.
Take Acetanilide as raw material, through chlorosulphonic acid, prepare p-acetaminobenzenesulfonyl chloride, then obtain the acetamido benzsulfamide through ammonolysis reaction, through hydrolysis, recrystallization obtains the finished product sulfanilamide (SN).

The complete mechanism for the conversion of acetanilide to p-acetamidobenzenesulfonyl chloride using chlorosulfonic acid and water is shown as: Acetanilide undergoes chlorosulfonation along two moles of chlorosulfonic acid. After this, it undergoes two phases, so as to give p-Acetamidebenzene-sulphonyl chloride.
