Vorschrift

Carbon dioxide was passed for 1 hour into 553 g of a 15.56% strength aqueous N,N-dimethylpiperidinium hydroxide solution. The solution heated up from 20° C. to 38° C. within 20 minutes, and then cooled down again. 300 ml of toluene was added to 100 ml of the solution. The resultant mixture was refluxed and the water was distilled off azeotropically over a period of 11 hours.
