4.4 Moles of a 30% aqueous solution of sodium hydroxide were dissolved in 4 moles of 2,2,2-trifluoroethanol with cooling to maintain the temperature of the reaction mixture between 50° and 55° C. The solution was added at once with stirring at the same temperature to a mixture of 4.2 moles of benzene sulphochloride and 1 liter of water, which had also been brought at 50°-55° C.
