Abstract

The present invention relates to a process for preparing a porous metal organic framework comprising at least one at least bidentate organic compound coordinated to at least one metal ion, which comprises the step

• • reaction of at least one metal compound with at least one at least bidentate organic compound which can coordinate to the metal, with the metal ion of the at least one metal compound being selected from the group of metals consisting of titanium, zirconium and hafnium and the at least one at least bidentate organic compound being derived from a dicarboxylic, tricarboxylic or tetracarboxylic acid,
    wherein the metal compound is an inorganic salt.

Claims

1-10. -10. (canceled)

11. A process for preparing a porous metal organic framework comprising at least one at least bidentate organic compound coordinated to at least one metal ion, which comprises:

reaction of at least one metal compound with at least one at least bidentate organic compound which can coordinate to the metal, with the metal ion of the at least one metal compound being selected from the group of metals consisting of titanium, zirconium and hafnium and the at least one at least bidentate organic compound being derived from a dicarboxylic, tricarboxylic or tetracarboxylic acid,

wherein the metal compound is an inorganic salt.

12. The process according to claim 11, wherein the metal is zirconium.

13. The process according to claim 11, wherein the at least bidentate organic compound is phthalic acid, isophthalic acid, terephthalic acid, 2,6-naphthalenedicarboxylic acid, 1,4-naphthalenedicarboxylic acid, 1,5-naphthalenedicarboxylic acid, 1,2,3-benzenetricarboxylic acid, 1,2,4-benzenetricarboxylic acid, 1,3,5-benzenetricarboxylic acid or 1,2,4,5-benzenetricarboxylic acid.

14. The process according to claim 11, wherein the inorganic salt of the at least one metal compound is a halide, sulfide, the salt of an inorganic oxygen-comprising acid, if appropriate in the form of a hydrate, or a mixture thereof.

15. The process according to claim 11, wherein the reaction is carried out in the present of a nonaqueous solvent.

16. The process according to claim 11, wherein the reaction is carried out with stirring.

17. The process according to claim 11, wherein the reaction is carried out at a pressure of not more than 2 bar (absolute).

18. The process according to claim 11, wherein the reaction is carried out without additional base.

19. The process according to claim 11, wherein the nonaqueous solvent is a C_1-6-alkanol, DMSO, DMF, DEF, acetonitrile, toluene, dioxane, benezene, chlorobenzene, MEK, pyridine, THF, ethyl acetate, optionally halogenated C_1-200-alkane, sulfolane, glycol, NMP, gamma-butyrolactone, alicyclic alchohols, ketones, cyclic ketones, sulfolene or a mixture thereof.

20. The process according to claim 11, wherein, after the reaction, the framework formed is after-treated with an organic solvent.
