Carbon capture, utilization and sequestration technol. is effective for carbon emissions reduction The development of new absorbent seems to be one of the core components of carbon capture technol. In this paper, three esters, Me heptanoate, Et hexanoate and Me benzoate, were selected to determine CO2 solubilities at different temperatures ranging from 293.15 to 333.15 K, and pressures up to 1.2 MPa, using the isothermal synthesis method. The results showed that the absorbent with the straight-chain alkyl group was more effective for improving CO2 absorption capacity than the benzene group. Et hexanoate showed slightly higher CO2 solubilities than its isomer Me heptanoate. In addition, Henry’s constant and thermodn. properties such as solution enthalpy, solution entropy, solution Gibbs energy and solution heat capacity, were determined based on the measured data since the above properties are essential for designing an absorption process. Et hexanoate is superior to the other two selected absorbents, common solvents, com. absorbents, some phys. absorbents, some polymeric absorbents and some ionic liquids, which indicates that it has potential value for CO2 capture technol. However, further studies will be necessary to assess the reliability of its industrial application. This study involved multiple reactions and reactants, such as Methyl heptanoate (cas: 106-73-0Computed Properties of C8H16O2).
Methyl heptanoate (cas: 106-73-0) 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. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.Computed Properties of C8H16O2
