Aluminum nitrate nonahydrate → Aluminum nitrate

Participants

Reaction Steps

375 g (1 mole) of aluminum nitrate nonahydrate (Al(NO3)3·9H2O)(manufactured by Kansai Catalyst Co., Ltd., reagent grade, appearance: powder) was dissolved in 778 g of water to obtain an aluminum nitrate solution. 110 g of seed crystal slurry described above (22 g in terms of Al2O3) was added to the aluminum nitrate solution and the obtained mixture was charged into a rotary evaporator, and dried at 60° C. under the reduced pressure to obtain a powdery mixture having 30% by weight of α-alumina as a seed crystal in terms of Al2O3.
