Method of activating metal-organic framework with dimethyl ether
A method of activating a metal-organic framework material can include solvent exchanging the metal organic framework material with DME and then applying a vacuum to remove the DME and any residual solvent.
1 . A method of treating a solvent-containing metal-organic framework material to displace the solvent, comprising contacting the solvent-containing metal-organic framework material with a dimethyl ether, wherein the dimethyl ether exchanges with solvent present in pores and coordinated on metal sites of the metal-organic framework material to thereby provide a metal-organic framework material exchanged with dimethyl ether.
2 . The method of claim 1 , wherein contacting the solvent-containing metal-organic framework material comprises:
flowing the dimethyl ether over the solvent-containing metal-organic framework material continuously, or
filling a container containing the solvent-containing metal-organic framework material with the dimethyl ether and holding for a hold time prior to venting the container.
3 . The method of claim 2 , wherein flowing the dimethyl ether over the solvent-containing containing metal-organic framework material comprises flowing the dimethyl ether into a container containing the solvent-containing metal-organic framework material continuously while continuously venting the container.
4 . The method of claim 2 , wherein the dimethyl ether is flowed at gaseous pressure and/or liquid pressure.
5 . The method of claim 1 , wherein the solvent present in the solvent-containing metal-organic framework material is one or more of an alcohol, a ketone, and a formamide.
6 . The method of claim 5 , wherein the formamide is diethylformamide (DEF) and/or dimethylformamide (DMF), the alcohol is methanol and/or ethanol, and/or the ketone is acetone.
7 . The method of claim 1 , wherein the solvent present in the solvent-containing metal-organic framework material is dimethylformamide (DMF) and/or methanol.
8 . The method of claim 1 , wherein the solvent-containing metal-organic framework material comprises coordinatively unsaturated metal sites and/or the solvent-containing metal-organic framework material is thermally sensitive.
9 . A method of activating a solvent-containing metal-organic framework material, comprising:
contacting the solvent-containing metal-organic framework material with a dimethyl ether, wherein the dimethyl ether exchanges with solvent present in pores and coordinated on metal sites of the metal-organic-framework material to thereby provide a metal-organic framework material exchanged with dimethyl ether; and
applying a vacuum to the metal-organic framework material exchanged with dimethyl ether to remove residual solvent and dimethyl ether to thereby activate the metal-organic framework material.
10 . The method of claim 9 , comprising heating the metal-organic framework material exchanged with dimethyl ether while applying the vacuum.
11 . The method of claim 10 , wherein the heating temperature is less than 150° C.
12 . The method of claim 10 , wherein the metal-organic framework material exchanged with dimethyl ether is in an oil-bath while heating and applying the vacuum.
13 . The method of claim 9 , wherein the vacuum is applied at room temperature.
14 . The method of claim 9 , wherein the solvent-containing metal-organic framework material comprises coordinatively unsaturated metal sites and/or the solvent-containing metal-organic framework material is thermally sensitive.
15 . The method of claim 9 , wherein contacting the solvent-containing metal-organic framework material comprises:
flowing the dimethyl ether over the solvent-containing metal-organic framework material continuously, or
filling a container containing the solvent-containing metal-organic framework material with the dimethyl ether and holding for a hold time prior to venting the container.
16 . The method of claim 15 , wherein flowing the dimethyl ether over the solvent-containing metal-organic framework material comprises flowing the dimethyl ether into a container containing the solvent-containing metal-organic framework material continuously while continuously venting the container.
17 . The method of claim 9 , wherein the dimethyl ether is flowed at gaseous pressure and/or liquid pressure.
18 . The method of claim 9 , wherein the solvent present in the solvent-containing metal-organic framework material is one or more of an alcohol, a ketone, and a formamide.
19 . The method of claim 18 , wherein the formamide is diethylformamide (DEF) and/or dimethylformamide (DMF), the alcohol is methanol and/or ethanol, and/or the ketone is acetone.
20 . The method of any one of claim 19 , wherein the solvent present in the solvent-containing metal-organic framework material is dimethylformamide (DMF) and/or methanol.
