{"product_id":"cgasmofzif90","title":"ZIF-90 (Zn(ICA)2) Metal Organic Frameworks (MOFs) Powder for Gas Absorption and Separation, CGASMOFZIF90","description":"\u003cp\u003eZIF-90 (Zn(ICA)2, where ICA = imidazolate-2-carboxaldehyde) is a sodalite-topology zeolitic imidazolate framework constructed from tetrahedrally coordinated Zn^{2+} nodes connected by 2-formylimidazolate linkers. It is isostructural with ZIF-8, but the replacement of the non-polar 2-methyl group (-CH3) with an electron-rich, polar aldehyde group (-CHO) provides both higher polarity for gas separation and a reactive platform for post-synthetic covalent modification.\u003c\/p\u003e\n\u003cp\u003eThe key structural and functional features of theZIF-90 are: (1) \u003cstrong\u003eSodalite (SOD) Pore Architecture\u003c\/strong\u003e: \u003cem\u003eCentral\u003c\/em\u003e \u003cem\u003ePore Cavity\u003c\/em\u003e: ~ 11.2 Å spherical cage. P\u003cem\u003eore Aperture\u003c\/em\u003e: 6-membered ring windows with a nominal crystallographic aperture of ~ 3.5 Å (effective dynamic aperture ~ 3.5–3.8 Å. (2) \u003cstrong\u003ePolar Aldehyde (-CHO) Pore Environment\u003c\/strong\u003e: The protruding carbonyl oxygens (C=O) project directly into the apertures and cages, providing strong local dipole fields that enhance electrostatic interactions with polar\/quadrupolar gas molecules (such as CO2 and SO2). (3) \u003cstrong\u003eChemical \u0026amp; Thermal Stability\u003c\/strong\u003e: Thermally stable up to ~ 300–350°C in air\/inert atmospheres. Resists boiling water, alcohols, and neutral-to-alkaline aqueous solutions, though like most ZIFs, it is sensitive to acidic environments (pH \u0026lt; 4–5).\u003c\/p\u003e\n\u003ctable border=\"1\" style=\"width: 100.071%; height: 257.125px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003ePart Number\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003eCGASMOFZIF90 (C-GAS-MOF-ZIF90)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003eCAS\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e936144-60-6\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003eColor\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003eLight Yellow Powder\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003eAverage Sizes\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e~100-200 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003e\u003cem\u003eBET\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e~1100-1400 m2\/g\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 26.875px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 26.875px;\"\u003e\u003cem\u003ePore Size\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 26.875px;\"\u003e0.3-1.2 nm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 71.2px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 71.2px;\"\u003e\u003cem\u003ePrimary Applications\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 71.2px;\"\u003e\n\u003cp\u003eGas absorption, storage, and separation. \u003c\/p\u003e\n\u003cp\u003eWastewater treatment, ion separation, \u003c\/p\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 24.675px;\"\u003e\n\u003ctd style=\"width: 24.6929%; height: 24.675px;\"\u003e\u003cem\u003ePackage Grade\u003c\/em\u003e\u003c\/td\u003e\n\u003ctd style=\"width: 72.8334%; height: 24.675px;\"\u003e5 g\/bottle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003e\u003cb\u003e\u003cbr\u003e\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eReferences:\u003c\/b\u003e\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003e\n\u003cb\u003e\u003c\/b\u003e\u003ca href=\"https:\/\/pubs.acs.org\/iecred\/article-abstract\/58\/23\/9997\/866805\/Separation-of-Ethane-from-Natural-Gas-Using-Porous?redirectedFrom=fulltext\"\u003eW.
