METHOD OF PRODUCING ALUMINOPHOSPHATES

摘要

PROBLEM TO BE SOLVED: To provide a method of producing aluminophosphates having high adsorption capacity, and free from the destruction of a crystal structure caused by repeated use under severe conditions and the reduction of the adsorption capacity caused thereby when used as an adsorbent. SOLUTION: In the method of producing template-containing aluminophosphates having a frame work density (FD) of 13 to 20 T/nm3by the hydrothermal synthesis using an aluminophosphates producing raw material mixture, in the process where the raw material mixture is heated-up to the maximum arrival temperature on the hydrothermal synthesis, it is held in the temperature range of 75 to 115°C for≥1.3 hr.
