Versuchsvorschrift

Adamantyltrimethylammonium methylcarbonate (383 g, 1.42 mol) is added to water (1000 mL), followed by addition of calcium hydroxide (148 g, 2.0 mol). This addition is exothermic. The reaction mixture is then heated to reflux and the methanol produced is slowly distilled off until the vapor temperature is constant. The reaction mixture is then cooled slowly to 10° C. and the precipitated calcium carbonate and excess calcium hydroxide are filtered off on a Nutsche filter. The filter cake is washed with water (200 mL) and both the mother and wash filtrates are combined. The 1-adamantyltrimethylammonium hydroxide product yield is 1284 grams of solution with assay 20.2% w/w.
