摘要：
Separation of C2H2/C2H4 to obtain polymer-grade C2H4 is important for manufacturing industry. However, due to the similar physicochemical properties, it is difficult to separate them. Herein, a thermostable and hydrostable metal-organic framework FJI-W-100 has been synthesized, which exhibits the structural characterization of a 2 -fold interpenetrated network. The narrow channel (ca. 5 angstrom) matches well with gas molecule. As expected, the framework possesses stronger interaction with C2H2 over C2H4. At 298 K and 1 bar, the adsorption capacity of C2H2 (64 cm3/g) is higher than C2H4 (54 cm3/g). Dynamic breakthrough experiments show that FJI-W-100 can effective separate C2H2/C2H4.
