Procedure

604 g of dimethyl carbonate, 394 g of trimethylamine, 300 g of water and 500 g of methanol were introduced in the same reactor as used in Preparation Example 1 and heated with stirring. After the temperature in the reactor reached 100° C., the reaction was continued for 3 hours at 100° C. Tetramethylammonium hydrogencarbonate was obtained in a yield of 90.3 mol % (based on trimethylamine).
