Crystallization of aluminophosphate gels prepared using boehmite and phosphoric acid with different di-n-propylamine/Al2O3 ratios was studied. Depending on the di-n-propylamine/Al2O3 ratio, the following intermediate phases can be formed in reaction gels in the course of further crystallization: hydrated aluminophosphate AlPO4·2H2O, the layered phase, and their mixtures. Procedures were suggested for controlling the morphology of the AlPO4-11 molecular sieve, based on variation of the template/Al2O3 ratio in the course of the reaction gel preparation.
