Reaction Steps

Aluminum nitrate nonahydrate (75 g, 0.2 mol) water (75 g, 4.2 mol) and crystal urea (15.5 g, 0.26 mol) were refluxed together for 16 hours. No fumes could be seen coming from the reactor during this period. The clear solution which resulted was analyzed for aluminum content and hydroxyl content and found to have a hydroxyl to aluminum ratio of 2.39:1. The hydroxyl content was determined by direct titration after the addition of potassium oxalate to prevent hydrolysis of the aluminum ion. There was no loss of nitrogen during the process and the final solution contained 186% by weight of ammonium nitrate based on the weight of the Al(OH)2.4 (NO3)0.6 found.
