| 英文摘要 | Upon heating the initial mixture with the composition of n(Al2O3) :n(P2O5) :n(en) :n(H2O) = 1:1:2:226 at 200 degrees C for 12 h, where en is ethylenediamine, a three-dimensional open-framework aluminophosphate AlPO4-12 was obtained. The crystallization process of AlPO4-12 was investigated using X-ray diffraction, elemental analysis, pH measurement, liquid NMR, and electrospray ionization mass spectra (ESI-MS). On the basis of the ESI-MS data, a method was developed to systematically enumerate the formula of the fragments formed during the crystallization of AlPO4-12. It was found that intermediate phases of layered aluminophosphates Ui0-15 and Ui0-13 were formed prior the crystallization of AlPO4-12. The concentration of Al species in the liquid throughout the crystallization was extremely low. A gradual increase of P-OH group in the P species in the liquid and a gradual protonation of ethylenediamine during the crystallization were observed. The formation of 4- and 6-membered rings was confirmed by the ESI-MS data. The utilization of ESI-MS in the investigation of the crystallization process of microporous crystalline materials may allow us to determine the structural information and the formula of the fragments formed during the crystallization. |
