An important intermediate called NKX-2 has been capturednin the crystallization of zeolite-like AlPO<sub>4</sub>-5. NKX-2 is a microporous aluminophosphite withnone-dimensional 12-member ring channels in its structure. It is acidic-stable in HCl solution and basic-stable under hydrothermal conditions at 200 °C for 15 days. An overview of this new route has beenndisplayed by XRD patterns on the formation of AlPO<sub>4</sub>-5 in a nonaqueous system. NKX-2 appeared firstnas an intermediate, and then reflections due to AlPO<sub>4</sub>-5 appeared gradually with the time evolution. Thenconversion of P(III) species to P(V) species in the crystallization has been detected by Raman investigation.nBesides, with use of NKX-2 as the starting material, by adding organic amine to the mixture of NKX-2nand water, AlPO<sub>4</sub>-5, AlPO<sub>4</sub>-41, and MeAPO-47 aluminophosphates have also been obtained hydrothermally.","PeriodicalId":523077,"journal":{"name":"Figshare","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2016-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147909332","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
