Investigation of the Fiban K-1 Sulfocationite by the IR Spectroscopy Method

Using the IR spectroscopy method, we have studied the state of water, sulfogroups, and adsorbed methanol in a Fiban K-1 fibrous cationite under different conditions of preparation of a sample. It is shown that on an air-dried cationite protonation of methanol is performed by the ionic pair [(H_2n+1O_n)⁺·SO₃^–] after vacuum treatment at 20°C and by the ionic pair [H⁺·SO₃^–] after vacuum treatment at 90°C.
