Official abstract text for this publication.
The metal organic framework (MOF) MIL-100 (Al) can be produced in a process in which aluminum nitrate and trimesic acid are brought to react with one another in an alcohol/water mixture under the action of NH 3 and/or an NH 3 -releasing compound under mild conditions.
Opening claim text (preview).
What is claimed is: 1. A process for producing MIL-100(Al), wherein aluminum nitrate and trimesic acid are brought to react with one another in an alcohol/water mixture under the action of a base, wherein the base is selected from the group consisting of NH 3 , an NH 3 -releasing compound, and mixtures thereof. 2. The process according to claim 1 , wherein the base comprises the NH 3 -releasing compound and the NH 3 -releasing compound is selected from the group consisting of urea, urotropine, ammonium carbamate and mixtures thereof. 3. The process according to claim 1 , wherein urea is used as the base. 4. The process according to claim 1 , wherein the alcohol used is selected from the group consisting of polyhydric alcohols and mixtures of polyhydric alcohols. 5. The process according to claim 1 , wherein the alcohol and the water are used in a ratio of 98:2 to 20:80 vol. % at room temperature. 6. The process according to claim 1 , wherein the reaction is carried out at a temperature below 200° C. 7. The process according to claim 4 , wherein the alcohol used is selected from the group consisting of glycerol, 1,2-propanediol, 1,3-propanediol and mixtures thereof. 8. The process according to claim 5 , wherein the alcohol and the water are used in a ratio of 80:20 to 40:60 vol. % at room temperature. 9. The process according to claim 6 , wherein the reaction is carried out at a temperature below 160° C.
