Abstract
This invention relates to a continuous process for the preparation of a metal-organic framework comprising a hydrophobic compound. The process comprises the steps of: (a) providing a first component comprising either (i) a metal-organic framework, or (ii) a first reactant which includes at least one metal in ionic form and a second reactant which includes at least one ligand capable of associating with the metal in ionic form in order to form a metal-organic framework. (b) providing a hydrophobic compound, and (c) mixing the first component and the hydrophobic compound in order to form the metal-organic framework comprising the hydrophobic compound. The invention also relates to the use of a hydrophobic polymer, a silane compound and/or a siloxane compound to improve the water stability of a metal-organic framework.
