Procedure
To 60 mL of water, 60 mL of ethanol and 2.0 mL of 37% concentrated hydrochloric acid were added, and then, 6.55 g (0.022 mol) of N,N-dimethyloctadecylamine was added. The mixture was heated to 60° C. to give a solution of N,N-dimethyloctadecylamine hydrochloride. To this solution, 20 g of montmorillonite was added. The thus-obtained slurry was stirred at 60° C. for 3 hours. The supernatant was removed, and the residual liquid was washed with 1 L of water at 60° C. and then dried at 60° C. under a pressure of 10−3 Torr for 24 hours. The dried product was pulverized by a jet mill to give a modified montmorillonite having an average particle diameter of 5.2 μm. Elemental analysis of the modified montmorillonite revealed that the amount of N,N-dimethyloctadecylammonium ion was 1.0 mmol per g of the modified montmorillonite.
