High solids concentration synthesis of metal-organic frameworks

A method of making a metal-organic framework composition, comprising:

• forming a mixture comprising one or more metal compounds, a solvent, and at least one multi-ring disalicylate linker, the mixture comprising a solids content of 35 wt % or more, a kinematic viscosity at 40° C. of 500 cSt or more, or a combination thereof;
• and
• reacting the mixture for a reaction time to form a composition comprising a metal-organic framework,
• wherein the metal-organic framework comprises at least one metal of the one or more metal compounds and the at least one multi-ring disalicylate organic linker, and
• i) wherein the method further comprises mixing the mixture, and wherein forming the mixture comprises adding the one or more metal compounds and the at least one multi-ring disalicylate linker to at least a portion of the solvent prior to mixing of the one or more metal compounds and the at least one multi-ring disalicylate linker;
• ii) wherein forming of the mixture comprises adding the solvent prior to addition of at least a portion of the one or more metal compounds;
• iii) wherein forming of the mixture comprises adding the solvent prior to addition of at least a portion of the at least one multi-ring disalicylate linker;
• or
• iv) a combination of two or more of i), ii), and iii).
