Claims
- 1. A synthetic ETS-4 titanium silicate containing greater than 5% of a polymorph phase characterized as having pores which interpenetrate the framework of the ETS-4 in the b- and c-directions.
- 2. The synthetic ETS-4 titanium silicate of claim 1, wherein said pores in the c-direction include c-directed channels formed from 12-membered pores.
- 3. The synthetic ETS-4 titanium silicate of claim 1, wherein said titanium silicate includes alkaline earth metal cations exchanged thereon.
- 4. The synthetic ETS-4 titanium silicate of claim 3, wherein said alkaline earth metal cations include barium, calcium or strontium.
- 5. The synthetic ETS-4 titanium silicate of claim 1, containing at least 20% of said polymorph.
- 6. A synthetic ETS-4 titanium silicate, which comprises greater than 5% of at least one polymorph phase of ETS-4 which contains non-faulted channels which penetrate the ETS-4 framework in the c-direction.
- 7. The synthetic ETS-4 titanium silicate of claim 6, comprising a mixture of two of said polymorphs, which contain channels which interpenetrate the framework of ETS-4 in the c-direction.
- 8. The synthetic ETS-4 titanium silicate of claim 6, which is exchanged with alkaline earth metal cations.
- 9. The synthetic ETS-4 titanium silicate of claim 8, wherein said alkaline earth metal cations include barium, calcium, or strontium.
- 10. The synthetic ETS-4 titanium silicate of claim 6 containing at least 20% of said at least one polymorph phase.
- 11. A synthetic, crystalline titanium silicate having a composition in terms of mole ratios of oxides as follows:
- 12. The synthetic, titanium silicate of claim 11, wherein said additional line of said X-ray powder diffraction pattern is at a d-spacing of 12.5±0.25 Å.
- 13. The synthetic, titanium silicate of claim 11, wherein said additional line of said X-ray powder diffraction pattern is at a d-spacing of 13.9±0.25 Å.
- 14. The synthetic, titanium silicate of claim 11 wherein the ration of peak heights of said additional line to said line at 11.65±0.25 Å is greater than 20%
- 15. The synthetic ETS-4 titanium silicate of claim 1, which has been heat treated to reduce the pores in the b-direction to less than 4 Å and the pores in the c-direction to less than 6 Å.
- 16. The synthetic ETS-4 titanium silicate of claim 5, which has been heat treated to reduce the channels in the c-direction to less than 6 Å in diameter.
