Methylamine Separations Enabled by Cooperative Ligand Insertion in Copper-Carboxylate Metal-Organic Frameworks.

ABSTRACT: Monomethylamine (NH₂CH₃), dimethylamine (NH(CH₃)₂), and trimethylamine (N(CH₃)₃) are important chemical feedstocks that are produced industrially as an azeotropic mixture and must be separated using an energy-intensive thermal distillation. While solid adsorbents have been proposed as alternatives to distillation for separating various industrial gas mixtures, methylamine separations remain largely unexplored in this context. Here, we investigate two isoreticular frameworks Cu(cyhdc) (cyhdc^2- = trans-1,4-cyclohexanedicarboxylate) and Cu(bdc) (bdc^2- = 1,4-benzenedicarboxylate) as prospective candidates for this challenging separation, motivated by the recent discovery that Cu(cyhdc) reversibly cap
