실험 절차

Titanium phosphate was prepared by the following procedure. Hydrochloric acid (500 g) was added to 5 liters of water, and 500 g of titanium tetrachloride was added dropwise at room temperature. After allowing the mixture to stand for 3 hours, a 10% aqueous solution containing 356 g of diammonium hydrogen phosphate was gradually added dropwise to the mixture with thorough stirring. After the formation of a precipitate, the system was allowed to stand at 70° C. for 6 hours. The precipitate was separated by filtration, and washed with water by means of a centrifugal separator until there was no chlorine ion in the filtrate. It was dried at 120° C., and then calcined at 550° C. for 3 hours. The resulting powder had the composition 2TiO2.P2O5 and a surface area, measured by the BET method, of 72 m2 /g.
