Hydrochloric Acid → HCID 11480951, compound

Participants

Reaction Steps

200 g (1.78 mol) of 4-fluorophenol are dissolved under a nitrogen atmosphere in 1300 ml of CHCl3 (distilled, dried over CaCl2). Added dropwise to this solution, over a period of 1 hour at room temperature with stirring, are 131 ml (229 g=1.96 mol) of chlorosulfonic acid, a vigorous release of HCl being observed initially, which dies down 30 min after completion and ceases entirely after a further 3 hours. After a reaction time of 24 hours, the precipitated product is filtered off with suction at room temperature under inert gas, washed twice with 200 ml of CHCl3 each time, and dried in vacuo at 1333 Pa and room temperature for 3 hours.
