POROUS CRYSTALLINE MATERIALS, THEIR SYNTHESIS AND APPLICATION Russian patent published in 2015 - IPC C07F1/02 C07F5/02 C01B39/00 B01D53/04

Abstract RU 2546652 C2

FIELD: chemistry.

SUBSTANCE: invention relates to porous crystalline materials. A porous crystalline material having a tetrahedral framework comprising the general structure M¹-IM-M², wherein M¹ comprises a metal having the first valency, M² comprises a metal having the second valency different from the first valency, and IM is imidazolate or a substituted imidazolate linking moiety. One or more of the following conditions is met: M¹ comprises a monovalent metal, and M² comprises a trivalent metal; M¹ is Li⁺; and M² is B³⁺. Also claimed is a gas adsorption method, a method of separating gas from a fluid stream containing the gas.

EFFECT: adsorbents with an improved gas uptake on a gravimetric basis.
