Versuchsvorschrift

105 parts of 2[2,4-dinitrophenylsulfonyl]ethanol are gradually added at 0°-5° C. to 380 parts of sulfuric acid monohydrate and the mixture is stirred at that temperature for 14 hours. The resulting brown solution is then gradually discharged onto a mixture of ice and 20% sodium chloride solution, the result being a yellowish suspension. The precipitate is filtered off and washed initially with 1000 parts of cold 20% sodium chloride solution and then with 200 parts of ice-water. Drying leaves 2-[2,4-dinitrophenylsulfonyl]ethyl hydrogensulfate in very good yield and purity.
