A new microporous organic polymer (PCB?NH2) has been synthesized based on amine functionalized carbazole derivative by oxidative coupling polymerization with anhydrous FeCl3. Polymer PCB-NH2 exhibits microporous nature with a BET surface area of 542.4 m2 g?1, and shows moderately high CO2 and C2H2 adsorption capacities, 51.6 cm3 g?1 (10.3 wt%), 58.4 cm3 g?1 (7.5 wt%) at 278 K, 1 atm, respectively. Remarkably, at 278 K, the predicted IAST selectivities of PCB-NH2 are 16.7?5.8 for a CO2/CH4 (5:95 v/v) gas mixture and 34.3?21.0 for a C2H2/CH4 (50:50 v/v) gas mixture at pressures varying from 0 to 1 atm, respectively. More interesting, PCB-NH2 displays higher CO2/CH4 selectivity than its matrix polymer PCB. The isosteric heats of CO2 adsorption (Qst) for PCB-NH2 and PCB further indicate that the amine group may facilitate the interaction between the polarizable CO2 molecules and the polymer by local dipole?quadrupole interactions, subsequently favors selective gas separation for these gas molecules. The high selectivity of CO2/CH4 and C2H2/CH4 makes PCB-NH2 possible candidate for future natural gas upgrading and acetylene purification.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 21436-03-3 is helpful to your research., Electric Literature of 21436-03-3
