Procedure

6-Hydroxyhexyl perfluoroisopropyl ether (15.5 g, 0.05 m) and sulfamic acid (5.1 g, 0.05 m) were combined and heated with stirring at 145° for one hour. Hexane (25 ml) was added to the cooled reaction mixture to remove unreacted alcohol. Filtration and vacuum drying gave a brown soft solid product, 6-hydroxyhexyl perfluoroisopropyl ether ammonium sulfate which was designated as Product I (B). IR analysis showed the following major absorption bands: 3200, 2935, 2860, 1430, 1210 cm-1.
