Claims
- 1. A process for pillaring a layered material which comprises:
- (a) preparing the layered material in the proton form;
- (b) intercalating an amine; and
- (c) displacing the intercalate with an inorganic pillaring substance.
- 2. A process as recited in claim 1 wherein the amine is butylamine.
- 3. A process as recited in claim 1 wherein the amine is a polyether amine.
- 4. A process as recited in claim 1 further comprising the step of heat treating the layered material subsequent to introduction of the pillaring substance.
- 5. A process as recited in claim 1 wherein preparing the layered material in the proton form comprises contacting the layered material with an acid.
- 6. A process as recited in claim 1 wherein the pillaring substance comprises a polyoxycation.
- 7. A process as recited in claim 1 wherein the pillaring substance comprises the Keggin ion.
- 8. A process for pillaring a layered material which does not appreciably swell in water comprising:
- (a) swelling the layered material with an organic intercalate; and
- (b) displacing the intercalate with an inorganic pillaring substance.
- 9. A process for pillaring a layered material which does not appreciably swell in water comprising:
- (a) swelling the layered material with an organic intercalate comprising an amine, amide or dimethyl sulfoxide; and
- (b) displacing the intercalate with an inorganic polyoxycation pillaring substance.
- 10. A process for pillaring a layered material which does not appreciably swell in water comprising:
- (a) swelling the layered material with an organic intercalate comprising an amine, amide or dimethyl sulfoxide; and
- (b) displacing the intercalate with an inorganic polyoxycation pillaring substance comprising an aluminum polymer, zirconium tetramer, chromium polymer or bismuth polymer.
- 11. A process as recited in claim 10, wherein the amine is an alkyl amine.
- 12. A process as recited in claim 10 wherein the amine is a polyether amine.
- 13. A process for pillaring a layered material which does not appreciably swell in water comprising:
- (a) swelling the layered material with an organic intercalate comprising an alkyl amine or a polyether amine; and
- (b) displacing the intercalate with an inorganic pillaring substance comprising one or more of the following polyoxycations:
- [Al.sub.13 O.sub.4 (OH).sub.24 .multidot.12H.sub.2 O].sup.7+, [Zr(OH).sub.2 .multidot.bH.sub.2 O].sup.8+, Cr.sub.2 (OH) .sub.2.sup.4+, Cr.sub.3 (OH).sub.4.sup.5+, [Bi.sub.6 O.sub.4 (OH).sub.4 ].sup.7+.
- 14. The process of claim 13 wherein the layered material comprises .alpha.-zirconium phosphates, .gamma.-zirconium phosphates, .alpha.-titanium phosphates, or .gamma.-titanium phosphates.
- 15. A process for pillaring a layered material, said layered material comprising .alpha.-zirconium phosphate, .gamma.-zirconium phosphate, .alpha.-titanium phosphate, or .gamma.-titanium phosphate, the process comprising:
- (a) swelling the layered material with an intercalate comprising an alkyl amine or a polyether amine; and
- (b) displacing the intercalate with an inorganic pillaring substance comprising one or more of the following polyoxycations:
- [Al.sub.13 O.sub.4 (OH).sub.24 .multidot.12H.sub.2 O].sup.7+, [Zr(OH).sub.2 .multidot.4H.sub.2 O].sup.8+, Cr.sub.2 (OH) .sub.2.sup.4+, Cr.sub.3 (OH).sub.4.sup.5+, [Bi.sub.6 O.sub.4 (OH).sub.4 ].sup.7+.
