摘要：NOVELTY - Preparation of zirconium phosphate catalyst comprises adding dropwise 64 mL 1.0 mol ammonium dihydrogen phosphate aqueous solution to 32 mL 1.0 mol zirconium oxychloride octahydrate aqueous solution, stirring overnight, filtering, washing with water until pH is 6, testing chloride anion using silver nitrate solution, drying precipitate white precipitate at 100 degrees C for 12 hours and calcining at 100-700 degrees C for 4 hours to obtain zirconium phosphate catalyst with phosphorus and zirconium molar ratio of 1.54. USE - Method for preparing zirconium phosphate catalyst used for dehydration of glycerol to acrolein (claimed). ADVANTAGE - The catalyst has high catalytic activity and good stability.
