Patent ID: 6949238

Claim:
An AlPO 4 -5 zeotype microporous crystalline species produced in a hydrothermal process comprising the steps: a) mixing water, phosphorous acid, and a structure directing agent to produce a first mixture; b) mixing cetyl pyridinium chloride, n-butanol, and toluene to produce a second mixture; c) combining said first and said second mixtures to produce a reverse microemulsion; d) stirring said reverse microemulsion for a first period and time at a first temperature; e) adding aluminum triisopropoxide to said stirred reverse microemulsion; f) aging said aluminum triisopropoxide containing reverse microemulsion for a second period of time at a second temperature; g) adding hydrofluoric acid to said aged aluminum triisopropoxide containing reverse microemulsion; h) aging said hydrofluoric acid containing and aluminum triisopropoxide contain reverse microemulsion for a third period of time at a third temperature; i) transferring said reverse microemulsion to a suitable heating vessel; and j) heating said transferred reverse microemulsion to a temperature of between about 100° C. and 220° C. for a selected period of time.
