実験手順

Nineteen grams of TiCl4 were dissolved in 500 ml of 1N-HCl. Separately, 24 grams of 85 vol % phosphoric acid were diluted with 500 ml of distilled water. After which the two solutions were mixed at room temperature with stirring. The formation of precipitate began with the mixing of the two solutions. Next, the pH of the solution was adjusted to 5.0 by gradually adding concentrated ammonia water, followed by allowing the solution to stand for 24 hours. The precipitate was then separated by filtration, water-washed and dried at 300°C. for one hour. The so obtained titanium phosphate had a specific surface area of 169 m2 /gm. The mole ratio PO4 /Ti at the time of catalyst preparation was 2.0 in this case.
