Production of metal-organic frameworks

A process for producing metal organic frameworks, the process comprising:

• mixing at least two different precursor solutions for forming the metal organic framework (MOF) through inline mixing to form a solution mixture, the precursor solutions comprising a first precursor solution comprising at least one multidentate linking ligand in water;
• and a second precursor solution comprising a metal cluster or metallic salt thereof in water,
• introducing the solution mixture into an apparatus which comprises:
• a tubular flow reactor which comprises a tubular body having an inlet into which, in use, the solution mixture is fed and flows, said tubular body including at least one annular loop comprising a coil;
• and
• promoting a reaction within the tubular flow reactor to form the metal organic framework,
• wherein the precursor solutions are mixed through inline mixing in a feed conduit fluidly connected to the inlet of the tubular body and the resulting solution mixture being fed into said inlet,
• and wherein the solution mixture flows through said tubular body mixing the precursor compounds therein to produce the metal organic frameworks.
