Abstract
A method is described for modifying an ultra-large pore crystalline material by contacting with a treatment composition M'X'Y'.sub.n wherein M' is an element of Groups IIA, IVA, VA, VIA, VIIA, IB, IIB, IVB, VB or VIB; X' is halide, hydride, alkoxide of C.sub.1-6', or acetate; Y' is X or phosphine, sulfide, carbonyl or cyano; and N=1-5. The contacted crystalline material becomes functionalized. The functionalized material is also described and can be used as a sorbent or catalyst component.
Claims20
A method for modifying a composition of matter which comprises an inorganic, porous, non-layered crystalline phase material exhibiting, calcination and/or functionalization, an X-ray diffraction pattern with at least one peak at a d-spacing greater than about 18 Angstrom Units with a relative intensity of 100 and having a benzene adsorption capacity of greater than 15 grams benzene per 100 grams benzene per 100 grams anhydrous crystal at 50 torr and 25.degree. C., comprising:
- contacting with a treatment composition comprising M'X'Y'.sub.n wherein
- M' is selected from a group consisting of Periodic Table Groups IIA, IIIA, IVA, VA, VIA, VIIIA, IB, IIB, IIIB, IVB, VB and VIB;
- X' is selected from a group consisting of halides, hydrides, alkoxyides of 1 to about 6 carbon atoms, alkyl of C.sub.1-18, alkenyl of C.sub.1-18, aryl of C.sub.1-18, aryloxide of C.sub.1-18, sulfonates, nitrates and acetates;
- Y' is selected from a group consisting of X', amines, phosphines, sulfides, carbonyls and cyanos;
- and
- n=1-5;
- said contacting occurring under sufficient conditions so that the crystalline phase material is functionalized.
