The advantages and disadvantages of amine-based materials for adsorptive CO2 capture have been well addressed so far. In order to maintain their high adsorption efficiency and long-term stability in treatment of complex flue gas, here we selected linear pentaethylenehexamine (PEHA) with in-depth epoxide functionalization to inhibit O2, CO2, and SO2 induced deactivation. We enveloped the functionalized PEHA into the hydrophobic polypropylene/polyolefin elastomer open-cell foams via epoxy resin crosslinking to prevent amine leaching and reduce water adsorption. Using the phase inversion and the supercritical CO2 foaming technologies, we controlled the cells with micron sizes and 88% porosity. The loss of adsorption capacity due to amine conversion has been successfully compensated by improving the loading ratio up to 65 weight%. To the best of our knowledge, this is the highest loading among amine-functionalized materials. Coupled with the PSA process, the stability of PEHA has been extended to the maximum extent in the prerequisite of ensuring high CO2 adsorption efficiency. In the experiment, the researchers used many compounds, for example, 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8Recommanded Product: 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)).
2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate) (cas: 6683-19-8) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Recommanded Product: 2,2-Bis(((3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoyl)oxy)methyl)propane-1,3-diyl bis(3-(3,5-di-tert-butyl-4-hydroxyphenyl)propanoate)
