Formula: C6H5Br2NThis research focused onzinc aminophenylenediacrylate MOF preparation selective acetylene methane ethylene separation; crystal structure zinc aminophenylenediacrylate metal organic framework. The article conveys some information:
The efficient separation of C2H2vs. C2H4 and CH4 to obtain high-purity C2H2 and C2H4 is of significance for making full, economic use of these raw chems. Herein, an amino-coordination microporous metal-organic framework ZJU-198, ZnL·DMF (ZJU = Zhejiang University, L = (2E,2E’)-3,3′-(5-amino-1,3-phenylene)diacrylic acid, DMF = N,N’-DMF), was demonstrated as a valuable adsorbent for C2H2/C2H4 and C2H2/CH4 separations The activated ZJU-198a exhibits moderate C2H2 uptakes (99.4 cm3 cm-3 for 273 K and 98.4 cm3 cm-3 for 298 K under 1.0 bar) and moderately high C2H2/C2H4 selectivity (5.8 to 7.7 at 273 K and 4.8 to 7.2 at 298 K). Specifically, the C2H2/CH4 selectivity of ZJU-198a reaches up to 497.9 and 391.1 at 273 K and 298 K, resp. To the best of the authors’ knowledge, the C2H2/CH4 selectivity coefficients of ZJU-198a at both 298 K and 273 K are the highest values among the reported metal-organic frameworks, meaning that there is bright potential for ZJU-198a in hydrocarbon storage and separation After reading the article, we found that the author used 3,5-Dibromoaniline(cas: 626-40-4Formula: C6H5Br2N)
3,5-Dibromoaniline(cas: 626-40-4) belongs to anime. Large quantities of aliphatic amines are made synthetically. The most widely used industrial method is the reaction of alcohols with ammonia at a high temperature, catalyzed by metals or metal oxide catalysts (e.g., nickel or copper). Mixtures of primary, secondary, and tertiary amines are thereby produced.Formula: C6H5Br2N
