Abstract
The method according to this disclosure is a method for separating an unsaturated hydrocarbon having 2 or 3 carbon atoms and a halogenated unsaturated carbon compound formed by replacing at least one of hydrogen atoms included in the unsaturated hydrocarbon with a fluorine atom, from each other and is a method for selectively adsorbing either the unsaturated hydrocarbon or the halogenated unsaturated carbon compound by a porous coordination polymer that includes a metallic ion having a valence of 2 to 4 and an aromatic anion having 1 to 6 aromatic ring(s).
Claims12
A method for separating an unsaturated hydrocarbon having 2 or 3 carbon atoms and a halogenated unsaturated carbon compound having 2 or 3 carbon atoms from each other, the method comprising:
- contacting a porous coordination polymer with a mixture including both the unsaturated hydrocarbon having 2 or 3 carbon atoms and the halogenated unsaturated carbon compound having 2 or 3 carbon atoms, wherein
- either the unsaturated hydrocarbon or the halogenated unsaturated carbon compound is selectively adsorbed to the porous coordination polymer, and
- the porous coordination polymer is represented by a composition formula [Cr3O(OH)(bdc)3] where bdc is 1,4-benzenedicarboxylate, [Zr6O4(OH)4(bpdc)6] where bpdc is 4,4′-biphenyldicarboxylate, or [Ni2(dhtp)] where dhtp is 2,5-dihydroxyterephthalate.
A method for separating a plurality of halogenated unsaturated carbon compounds from each other that are different from each other and that each have 2 or 3 carbon atoms, the method comprising:
- contacting a porous coordination polymer with a mixture including the plurality of halogenated unsaturated carbon compounds, wherein
- any one of the plurality of halogenated unsaturated carbon compounds is selectively adsorbed to the porous coordination polymer, and
- the porous coordination polymer is represented by a composition formula [Cr3O(OH)(bdc)3] where bdc is 1,4-benzenedicarboxylate, [Zr6O4(OH)4(bpdc)6] where bpdc is 4,4′-biphenyldicarboxylate, or [Ni2(dhtp)] where dhtp is 2,5-dihydroxyterephthalate.
A method of adsorbing or storing a halogenated unsaturated carbon compound having 2 or 3 carbon atoms, the method comprising:
- contacting a porous coordination polymer with the halogenated unsaturated carbon compound, and
- the porous coordination polymer is represented by a composition formula [Cr3O(OH)(bdc)3] where bdc is 1,4-benzenedicarboxylate, [Zr6O4(OH)4(bpdc)6] where bpdc is 4,4′-biphenyldicarboxylate, or [Ni2(dhtp)] where dhtp is 2,5-dihydroxyterephthalate.
