Reaction Conditions

Reaction Steps

A 2.5 m3 stirred vessel is charged with 2.5 t of water and 533 kg of 1-adamantyldimethylamine. Subsequently, 191 kg of dimethyl sulfate are metered in and the resulting reaction mixture is reacted at 30 to 50° C. for 2 hours. Subsequently the tank is heated to 140° C., an internal pressure of 4 bar being attained, and reaction continues at this temperature for 16 hours. The quaternization product is subjected to distillative removal of water, giving a 30% to 33% strength by weight solution of 1-adamantyltrimethylammonium sulfate. Conversion: 99%
