| abstract | 1362041 Vinyl sulphonates and vinylsulphonic acid BADISCHE ANILIN- & SODA-FABRIK AG 29 Nov 1971 [30 Nov 1970] 55269/71 Heading C2C Vinyl sulphonates or vinylsulphonic acid are made by treating carbyl sulphate under alkaline conditions optionally followed by liberation of vinylsulphonic acid by treatment of the resulting vinyl sulphonate with acid. The vinyl sulphonate is prepared in two stages, in the first of which there is added to an aqueous basic solution or suspension, e.g. of sodium or calcium hydroxide, an amount of carbyl sulphate which is equivalent to the hydroxyl ion portion of the solution or suspension, the addition being effected at such a rate that the pH of the mixture during the addition remains in the range 9 to 12 and the temperature remains in the range 30 to 50‹ C., and in the second stage the mixture is heated to from 70 to 150‹ C. |
