THE ALUMINOPHOSPHATE PST-5 AND PST-6 AND THEIR MANUFACTURING PROCESS

摘要

The present invention relates to aluminophosphates having novel structures and a preparation method thereof. More specifically, the present invention relates to the aluminophosphate PST-5 having a novel structure of including an organic structure derived molecule and a hydroxyl group in pores and aluminophosphate PST-6 having another novel structure prepared by firing the aluminophosphate PST-5 at 550°C as well as the preparation method thereof. The aluminophosphate PST-5 and PST-6 have an oxide composition of the mole ratio represented in the chemical formula 1 and a distinctive X-ray diffraction pattern including grid gaps. The chemical formula 1 can be represented by 0.5-1.5 Al_2O_3: 1.0 P_2O_5.
