Technical Field
The invention belongs to the technical field of inorganic and material chemistry, and particularly relates to a metal organic framework material and a preparation method and application thereof.
Background
Acetylene is one of the most widely used raw materials in the petrochemical field. However, due to limitations of the production process, acetylene often contains impurities such as carbon dioxide, hydrogen, carbon monoxide, and the like. Among these impurities, carbon dioxide has a similar boiling point, molecular size/shape, kinetic diameter to acetylene. The selective separation of acetylene from carbon dioxide is therefore a particularly important but extremely difficult industrial step.
The traditional methods for purifying acetylene are energy intensive industries that are not environmentally friendly. Therefore, it is urgent to develop alternative methods for green energy saving. Physical adsorption separation using crystalline porous materials is considered to be a promising separation technique.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail with reference to embodiments, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The metal organic framework material is a crystalline porous material, and has been highly regarded by researchers because of its adjustable pore size and easy functionalization. Most metal organic framework materials have high acetylene/carbon dioxide selectivity because the functional groups of the metal organic framework materials can form hydrogen bonds and pi complexation with acetylene with stronger acidity and high polarization, and the adsorption capacity of the metal organic framework materials to acetylene is larger. However, the acetylene/carbon dioxide selective separation requires a desorption process to obtain a pure acetylene product, and the carbon dioxide/acetylene selective adsorbent can directly produce pure acetylene by only one-time adsorption, which means that the energy consumption is lower and the operation is simpler. Therefore, the preparation of the metal organic framework material capable of reversely separating the carbon dioxide/acetylene mixture has important practical significance.
The metal organic framework material has the chemical formula of [ Zn (atz) (BDC-Cl4)0.5]nWherein atz is deprotonated 3-amino-1, 2, 4-triazole and BDC-Cl4 is deprotonated tetrachloroterephthalic acid.
The asymmetric unit of the metal organic framework material consists of Zn2+Ion, 3-amino-1, 2, 4-triazole ligand and half tetrachloro terephthalic acid ligand. Zn2+Coordinate with three nitrogen atoms of three 3-amino-1, 2, 4-triazole ligands and one carboxyl oxygen atom of one tetrachloroterephthalic acid ligand to form a distorted tetrahedral geometrical configuration.
Two examples of the preparation of the above-mentioned metal-organic framework materials by the solvothermal method are presented below:
example 1:
s1, mixing 0.1mmol of zinc nitrate hexahydrate, 0.1mmol of 3-amino-1, 2, 4-triazole, 0.1mmol of tetrachloroterephthalic acid, 2mL of N, N-dimethylformamide and 0.5mL of water, and uniformly stirring to obtain a mixture.
S2, sealing the mixture in a 10mL glass bottle, heating to 105 ℃, keeping the temperature for 48 hours, then cooling to room temperature at the speed of 0.5 ℃/min, and then filtering the reactants in the glass bottle to obtain a colorless block-shaped reaction product.
S3, exchanging the reaction product with dichloromethane for 72h, and then activating under vacuum at 80 ℃ for 12 h.
Example 2:
s1, mixing 0.2mmol of zinc nitrate hexahydrate, 0.2mmol of 3-amino-1, 2, 4-triazole, 0.2mmol of tetrachloroterephthalic acid, 6mL of N, N-dimethylformamide and 2mL of water, and uniformly stirring to obtain a mixture.
S2, sealing the mixture in a 15mL glass bottle, heating to 95 ℃ and keeping the temperature for 48 hours, then cooling to room temperature at the speed of 0.5 ℃/min, and then filtering the reactants in the glass bottle to obtain a colorless massive reaction product.
S3, exchanging the reaction product with dichloromethane for 72h, and then activating under vacuum at 60 ℃ for 24 h.
Characterizing the structure of the prepared metal organic framework material:
the colorless bulk crystal prepared in example 1 was taken, and X-ray single crystal diffraction data of the colorless bulk crystal was collected by an X-ray single crystal diffractometer at room temperature.
By analyzing the X-ray single crystal diffraction data of the colorless bulk crystal, we obtained the following conclusions:
as shown in FIG. 1, the asymmetric unit of the metal-organic framework material consists of one Zn2+Ion, 3-amino-1, 2, 4-triazole ligand and half tetrachloro terephthalic acid ligand. Zn2+Coordinate with three nitrogen atoms of three 3-amino-1, 2, 4-triazole ligands and one carboxyl oxygen atom of one tetrachloroterephthalic acid ligand to form a distorted tetrahedral geometrical configuration. As shown in FIG. 2, Zn2+The ions are linked to the ligands to form a complex having a diameter of about
The porosity of the material is 25.2 percent.
The colorless bulk crystal obtained in example 2 was subjected to X-ray single crystal diffraction in the same manner, and by analyzing the X-ray single crystal diffraction data, we obtained the following conclusions:
the colorless bulk crystals obtained in example 2 have exactly the same structure as the colorless bulk crystals obtained in example 1.
The adsorption isotherms of the metal-organic framework material prepared in example 1 for carbon dioxide and acetylene at a temperature of 285K were measured using an Autosorb-iQ MP physisorption apparatus of corna, usa, and the adsorption isotherms obtained are shown in fig. 3.
The adsorption amount of the metal organic framework material to carbon dioxide is 34.6cm under 760mmHg and 285K3 cm-3. In contrast, the adsorption amount of acetylene at 760mmHg and 285K was 18.0cm, which is very low3 cm-3。
Therefore, the metal organic framework material has the largest adsorption on carbon dioxide, has little adsorption amount on acetylene, has obvious adsorption and separation selectivity on acetylene, and has potential application prospect in the aspect of adsorption and separation of carbon dioxide/acetylene.
The separation selectivity of the metal organic framework material to carbon dioxide/acetylene can be calculated by utilizing an ideal adsorption solution theoretical method.
The adsorption selectivity of the metal-organic framework material prepared in example 1 to equimolar carbon dioxide/acetylene at a temperature of 285K, calculated by the ideal adsorption solution theory, is shown in fig. 4.
As can be seen from fig. 4:
the selectivity of the metal-organic framework material for an equimolar mixture of carbon dioxide/acetylene at a pressure of 100kPa was 2.4;
this high selectivity indicates that: the metal organic framework material prepared by the invention has excellent performance of separating acetylene from carbon dioxide.
The metal organic framework material prepared by the invention has excellent selectivity to acetylene because: the electronegative chlorine atoms exist in the pore channels of the metal organic framework material, so that the charges of the pore channels are more matched with the charges of carbon dioxide, but acetylene is repelled, thereby promoting the diffusion of the carbon dioxide, inhibiting the diffusion of the acetylene and leading to good carbon dioxide/acetylene separation performance.
The above are specific embodiments of the present invention, but the structural features of the present invention are not limited thereto, and the present invention can be applied to similar products, and any changes or modifications within the scope of the present invention by those skilled in the art are covered by the claims of the present invention.
