Preparation of diacetonamine (diacetonamine hydrogenoxalate)

Preparation of diacetonamine (diacetonamine hydrogenoxalate)

50 ml of mesityl oxide are dissolved in 100 ml of alcohol, cooled in a freezing mixture to -10° C, and dry ammonia is passed into the solution until saturated. The solution is allowed to stand for 48 hours. The diacetonamine base is separated as the acid oxalate. 30 g of powdered oxalic acid are mixed with 120 ml of alcohol in a beaker placed in ice. The ammoniacal solution is gradually added with vigorous stirring so that the temperature does not rise above 20° C until the pasty mass is neutral. To the resulting mixture, which is nearly solid, further 30 g of powdered oxalic acid are added and stirred. The reaction mixture is poured in a round bottom flask fitted with reflux condenser and boil for 15 minutes to complete the reaction. The diacetonamine hydrogenoxalate is filtered hot and the solution cooled slowly to 0° C. The diacetonamine hydrogenoxalate separates in crusts, which are filtered. The yield from 50 ml of mesityl oxide is about 50 g of diacetonamine hydrogenoxalate. Diacetonamine can also be prepared directly by the action of ammonia on acetone.
