摘要

Abstract—The crystallization of aluminophosphate gels prepared using aluminum isopropoxide with di‑n-propylamine/Al2O3 was equal to 1.0, 1.4, and 1.8. It has been shown that changing the template/Al2O3 ratio in reaction gels leads to the formation of various intermediate phases during crystallization into the AlPO4-11 molecular sieve. A method for controlling its secondary porous structure based on regulating the template/Al2O3 ratio is proposed in reaction gels.
