  • MOLECULAR SIEVE WITH POINT-SIEVING STRUCTURE, ITS PREPARATION METHOD, AND APPLICATION IN ADSORPTIVE SEPARATION OF PROPYLENE AND PROPANE THEREOF
    Publication number: 20260208152
    Abstract: The present invention discloses a molecular sieve with a point-sieving structure, its preparation method, and its application in the adsorptive separation of propylene and propane. The molecular sieve is formed through coordination bonds among 1,2-ethanedisulfonate anions, 4,4?-dipyridyl sulfide, and Cu2+, with the chemical formula [MSL2]?, where M represents Cu2+, S denotes the 1,2-ethanedisulfonate anion, L denotes 4,4?-dipyridyl sulfide, and ? indicates that the molecular sieve is spatially extended from multiple MSL2 structural units. The molecular sieve features localized point-like pore constrictions. Preparation Method: A Cu2+ source, 1,2-ethanedisulfonate salt, and 4,4?-dipyridyl sulfide are mixed and reacted in a reaction solvent to obtain the molecular sieve.
