Aim: To prepare and submit Sulphanilamide from acetanilide. Requirements: Beaker, funnel, conical flask, Buchner funnel, acetanilide, chlorosulphonic acid, aqueous ammonia. Theory: For the preparation of sulphanilamide, acetanilide is treated with chlorosulphonic acid, which forms p-acetamidobenzene sulphonyl chloride, which on treatment with ammonia gives p-acetamidobenzene sulphonamide, followed by hydrolysis. Reactions involved: Step-I: Synthesis of p-acetamido benzene sulphonyl chloride: Step-II: Synthesis of p-acetamido benzene sulphonamide: Step-III: Synthesis of Sulphanilamide: Procedure: Step 1: Synthesis of p-acetamidobenzene sulphonyl chloride: Take 25 g powdered acetanilide in a two mouth round bottom flask fitted with dropping…
