Reaction Steps

118.1 g of calcium nitrate tetrahydrate were dissolved in 200 ml of water and heated to 80° C., a solution of 33 g of diammonium phosphate in 100 ml of water was added and the mixture was rendered basic with ammonia and was aged for 30 minutes. After cooling, filtration and washing, the precipitate was dried at 120° C. and calcined for 2 hours at 600° C. The powder obtained was converted into a novel molding according to catalyst preparation a).
