CROSS-REFERENCE TO RELATED APPLICATIONS 
     The present application is a 371 application of PCT/JP2020/019130 filed May 13, 2020 claiming priority from the Japanese Patent Application No. 2019-091542 filed May 14, 2019, and the disclosures of which are incorporated herein by reference in their entirety. 
    
    
     FIELD OF THE INVENTION 
     The present disclosure relates to a method for producing Metal-Organic Frameworks (MOFs). 
     BACKGROUND 
     A group of substances called Metal-Organic Framework has been attracting attention in fields such as gas storage and gas separation. The Metal-Organic Framework is a compound having a structure in which metal atoms are crosslinked with each other by an organic ligand, and typically has porosity. Metal-Organic Frameworks with porosity are also called Porous Coordination Polymers (PCPs). 
     A liquid phase synthesis method such as a solution method, a hydrothermal method, a microwave method, and an ultrasonic method has been typically used as a method for producing the Metal-Organic Framework. A solid phase synthesis method using a mortar, a ball mill or the like has also been used. In recent years, a method of synthesizing Metal-Organic Frameworks using a biaxial mixing apparatus called an extruder has also been reported. In this method, a Metal-Organic Framework is produced by admixing a first reactant containing a specific metal ion donor and a second reactant containing a specific organic ligand under conditions of prolonged and sustained pressure and shear sufficient to synthesize the Metal-Organic Framework (Patent Literature 1)

     DETAILED DESCRIPTION OF THE INVENTION 
     The production methods according to an embodiment of the present invention will hereinafter be described. When referring to the drawings, the same reference numerals are given to the components exhibiting the same or similar functions, and duplicate description will be omitted. 
     A method for producing a Metal-Organic Framework according to an embodiment of the present disclosure includes simultaneously and continuously applying a centrifugal force and a shear force to a formulation containing a metal ion donor, a multidentate ligand, and a solvent. The production method may comprise the steps of: preparing a formulation containing a metal ion donor, a multidentate ligand, and a solvent; and mixing the formulation while simultaneously and continuously applying a centrifugal force and a shear force to the formulation. Alternatively, this production may be carried out by sequentially adding the materials comprising the above-mentioned formulation into a reactor. 
     There are no particular restrictions on the type of Metal-Organic Frameworks (MOFs) to be produced. Appropriately combining the type and coordination number of the metal ion with the type and topology of the multidentate ligand leads to a MOF with a desired structure. The MOF may contain two or more types of metal elements, and may contain two or more types of multidentate ligands. The MOF may further contain monodentate ligand(s). The MOF may be porous. In other words, the MOF may be a Porous Coordination Polymer (PCP). 
     Specific examples of the MOF include those listed in the literatures below:
     Reference 1: Yabing He et al., Methane Storage in Metal-Organic Frameworks, Chem Soc Rev, 2014   Reference 2: Jarad A. Mason et al., Evaluating metal-organic frameworks for natural gas storage, Chem. Sci., 2014, 5, 32-51   Reference 3: WO2019/026872   

     As described above, the formulation used as a raw material for the MOF contains a metal ion donor, a multidentate ligand, and a solvent. As the metal ion donor and the multidentate ligand, any substance can be used as long as it is suitable as a combination for synthesizing a MOF. 
     The metal elements of the metal ion donor can be, for example, any elements belonging to alkali metals (Group 1), alkaline earth metals (Group 2), or transition metals (Groups 3 to 12). The metal element is typically selected from the group consisting of magnesium, calcium, iron, aluminum, zinc, copper, nickel, cobalt, zirconium, and chromium. The metal ion donor may contain a plurality of metal elements. Alternatively, a plurality of metal ion donors containing different metal elements may be used in combination. 
     As the metal ion donor, a metal salt is typically used. The metal ion donor may be an organic salt or an inorganic salt. The metal ion donor is typically selected from the group consisting of hydroxides, carbonates, acetates, sulfates, nitrates and chlorides. A plurality of metal ion donors containing the same metal element may be used in combination. 
     The multidentate ligand is typically an organic multidentate ligand and is preferably selected from the group consisting of carboxylic acid anions, amine compounds, sulfonic acid anions, phosphate anions, and heterocyclic compounds. Examples of the carboxylic acid anion include dicarboxylic acid anion and tricarboxylic acid anion. Specific examples include anions of citric acid, malic acid, terephthalic acid, isophthalic acid, trimesic acid, and derivatives thereof. Examples of the heterocyclic compound include bipyridine, imidazole, adenine, and derivatives thereof. 
     The type of solvent contained in the above formulation is not particularly limited, and a solvent generally used for synthesizing a MOF can be used. However, the solvent may preferably be a poor solvent for at least one of the metal ion donor and the multidentate ligand. With such a configuration, the formulation does not become a complete solution but becomes a semi-solid, typically a slurry, with solids remaining. This makes it possible to more effectively apply centrifugal force and shear force, which will be described later, to the above-mentioned formulation. Here, the term “poor solvent” for an object means that the solubility in a solvent of the object is 1 g/50 mL (=20 g/L) or less at 25° C. and at atmospheric pressure. Examples of solvents that can be used include water, alcohols such as methanol and ethanol, carboxylic acids such as formic acid and acetic acid, amides such as N, N-dimethylformamide (DMF) and N, N-diethylformamide (DEF), and esters such as ethyl acetate. A mixture of a plurality of solvents may also be used. 
     The amount of the solvent based on the total amount of the metal ion donor and the multidentate ligand is, for example, in a range of 30 to 2000% by weight, preferably in a range of 100 to 1000% by weight. Adopting such a configuration makes it possible to improve the production efficiency of the MOF. 
     The above formulation may further contain additional substances such as reaction accelerators. The reaction accelerators are, for example, a basic substance or an acidic substance, and preferably a basic substance. Examples of the basic substance include diethylamine, triethylamine, 2,6-lutidine, pyridine, imidazole, potassium hydroxide, and sodium hydroxide. Examples of acidic substance include formic acid, acetic acid, trifluoroacetic acid, sulfuric acid, nitric acid, hydrochloric acid, and phosphoric acid. As an additional substance, a plurality of reaction accelerators may be used in combination. As an additional substance, a reaction control agent may also be added. 
     The above formulation is mixed while simultaneously and continuously applying centrifugal force and shear force. This makes it possible to produce a MOF in a short time and with high quality. 
     Metal-Organic Frameworks tend to be slightly brittle when compared to ordinary organometallic compounds, as implied by the term “framework” therein. Therefore, it is difficult to produce a high-quality MOF without devising a specific production method. For example, in the case of a solid-phase synthesis method using a ball mill device or the like, an extremely strong force is intermittently applied to the raw material. Therefore, the quality of the resulting MOF varies widely. Further, even in the synthesis method using an extruder, as an extremely strong shear force is locally applied to the raw material under high pressure, the similar problem is likely to occur. 
     Therefore, the present inventors have considered that the above problem may be solved by simultaneously and continuously adding a centrifugal force and a shear force to the above formulation. Conventionally, such a method has been used exclusively for the purpose of dispersing and/or atomizing particles and droplets, and has not been used for material synthesis. However, the present inventors have found that the MOF can be produced in a short time and with high quality by diverting the above method to the production of the MOF. 
     Examples of the method of simultaneously and continuously applying centrifugal force and shear force to the above-mentioned formulation include the following. Initially, the formulation is introduced into a reaction vessel. Next, a rotary blade provided in the reaction vessel is rotated to stir the formulation at high speed. This rotation imparts centrifugal force to the formulation. Then, by this centrifugal force, the above-mentioned compound is pressed against an inner wall of the reaction vessel. The contact between such a formulation and the inner wall of the reaction vessel imparts a shear force to the formulation. In this way, both centrifugal force and shear force are applied to the formulation simultaneously and continuously. In this state, the metal ion donor in the formulation reacts with the multidentate ligand to obtain a MOF. The shearing force may also be generated when the particles constituting the formulation come into contact with each other. 
     When the above method is used, the rotation axis of the rotary blade is preferably parallel to the direction of gravity. In this case, the unevenness of the centrifugal force and the shear force applied to the formulation by rotation is reduced as compared with, for example, the case where the rotation axis is perpendicular to the gravity direction. 
     One example of such a method is the thin film swirl mixing method developed by Primix Corporation. In this method, by using a thin film swirling high-speed mixer, centrifugal force and shear force can be simultaneously and continuously applied to the introduced substance. As a result, in the conventional use example, particles and droplets are dispersed and/or atomized. Specific device configurations are disclosed, for example, in JPA2007-125454. 
       FIG. 1  is a cross-sectional view schematically illustrating an example of a reactor used in a production method according to an aspect of the present invention. The reactor  100  shown in  FIG. 1  is a batch type manufacturing device. 
     The reactor  100  includes a reaction vessel  102 . The reaction vessel  102  is, for example, cylindrical. The reaction vessel  102  typically includes an outer layer  104  for temperature control. The outer layer  104  is configured so that a liquid such as water can be injected. This makes it possible to control the temperature in the reaction vessel  102 , particularly the temperature of the inner wall IW, which will be described later. 
     The reactor  100  includes a rotary blade  106 A and a rotary shaft  106 B connected thereto inside the reaction vessel  102 . The rotary blade  106 A can be configured to rotate by the rotation R of the rotary shaft  106 B. The rotary blade  106 A is, for example, a cylindrical wheel having a slight gap with the inner wall IW of the reaction vessel  102 . The wheel is typically provided with a number of holes for the formulation F to pass through. 
     A dam  108  is provided on the upper side of the reactor  100 . This prevents the reactants from leaking to the upper part of the reactor  100 . 
     In the production method using the reactor  100 , initially, the formulation F is introduced into the reaction vessel  102 . Next, the formulation F is stirred by rotating the rotary blade  106 A through the rotary shaft  106 B. Due to the centrifugal force applied to the formulation F, the formulation F is pressed against the inner wall IW while rotating. As a result, not only the above-mentioned centrifugal force but also a steady shearing force is applied to the formulation F. In this way, the formulation F is mixed while simultaneously and continuously applying centrifugal force and shear force. After completion of the reaction, the reaction product is recovered to obtain a desired MOF. 
       FIG. 2  is a cross-sectional view schematically illustrating an example of a reactor used in a production method according to another aspect of the present invention. The reaction device  200  shown in  FIG. 2  is a continuous type manufacturing device. 
     The reactor  200  includes a reaction vessel  202 . The reaction vessel  202  is provided with two outer layers for temperature control. Specifically, in addition to the outer layer  204 A having the similar structure as the outer layer  104 , an additional outer layer  204 B is provided on the upper part of the reaction vessel  202 . This makes it possible to control the reaction temperature even in the upper part of the reaction vessel  202 . 
     The reactor  200  includes a rotary blade  206 A and a rotary shaft  206 B connected thereto inside the reaction vessel  202 . The configurations of the rotary blade  206 A and the rotary shaft  206 B are the same as those described for the rotary blade  106 A and the rotary shaft  106 B, respectively. 
     A dam  208  is provided on the upper side of the reactor  200 . The dam  208  is smaller in size than the dam  108 . This allows at least a portion of the reaction product to be delivered to the upper part of the reactor  200 . 
     The reactor  200  includes an injection port  210 A and a discharge port  210 B. The injection port  210 A is provided in the lower part of the reactor  200  through which the formulation F can be continuously injected. The discharge port  210 B is provided in the upper part of the reactor  200 , through which at least a part of the reaction product can be discharged to the outside of the system. 
     In the production method using the reactor  200 , initially, the formulation F is introduced into the reaction vessel  202  through the injection port  210 A. Next, the formulation F is stirred by rotating the rotary blade  206 A through the rotary shaft  206 B. Due to the centrifugal force applied to the formulation F, the formulation F is pressed against the inner wall IW while rotating. As a result, not only the above-mentioned centrifugal force but also a steady shearing force is applied to the formulation F. In this way, the formulation F is mixed while simultaneously and continuously applying centrifugal force and shear force. The reaction product obtained by this mixing is discharged from the discharge port  210 B as the reaction progresses. By recovering the reaction product discharged in this way, a desired MOF is obtained. 
     Specific devices for enabling the above-mentioned manufacturing method include, for example, FILMIX (Primix Corporation), Apex Disperser ZERO (Hiroshima Metal &amp; Machinery Chemtech Co., Ltd.), and High-Shear Mixer (SILVERSON). Any device other than these may be used as long as it can simultaneously and continuously apply both centrifugal force and shear force to the formulation. 
     The above production is preferably carried out while controlling the reaction temperature. In that case, the mixing is preferably carried out at a temperature lower than the normal boiling point of the solvent. The mixing is carried out, for example, at a temperature of 80° C. or lower, preferably 60° C. or lower. In this way, it is possible to produce MOF in a state in which the solvent in the formulation remains in appropriate amount. 
     The production can be carried out while supplying at least one gas selected from the group consisting of dry air, argon, nitrogen, and oxygen into the reaction vessel. That is, in the production method according to one embodiment of the present invention, the reaction can be carried out in a closed system. For example, by performing the above production in an atmosphere of an inert gas such as dry air, argon, and nitrogen, it is possible to produce a moisture sensitive MOF with high accuracy. Alternatively, by performing the above production in an oxygen atmosphere, it becomes possible to produce a MOF that is preferably synthesized in an oxygen excess atmosphere with high accuracy. 
     Further, the above production can be carried out, for example, by mixing the formulation at a linear velocity in the range of 1 to 100 m/s, preferably at a linear velocity of 10 to 50 m/s. If the linear velocity is too low, it may not be possible to sustainably apply shear forces to the formulation. If the linear velocity is too high, the centrifugal and shear forces applied to the formulation may be excessive.

     Comparing Tables 1 and 2, it can be seen that by using the production method according to the present invention, higher quality MOFs can be synthesized while significantly shortening the reaction time compared with the case of using the conventional solvothermal method. Comparing Table 1 with Tables 3 and 4, it can be seen that by using the production method according to the present invention, higher quality MOFs can be synthesized with a similar reaction time, which is comparable to the case of using the conventional ball-mill method and the biaxial kneading method. 
     Further, when Examples 1 to 4 are compared as in Table 1, it can be seen that the specific surface area of the obtained MOF varies by controlling the amount of the solvent. This result suggests that the centrifugal force and shear force applied to the formulation can be optimized by controlling the viscosity of the formulation by adjusting the amount of solvent. 
     Further, in Table 1, when Examples 1, 5 and 6 or Examples 8 and 9 are compared, it can be seen that higher quality MOF can be synthesized by performing the reaction at a temperature below the normal boiling point of the solvent (78.4° C. in the case of ethanol, 64.7° C. in the case of methanol), preferably below 60° C. 
     Further, comparing Examples 20 to 23 in Table 1, it can be seen that a higher quality MOF can in some cases be synthesized by carrying out the reaction in a dry air, nitrogen, or argon atmosphere. Similarly, comparing Examples 24 and 25 in Table 1, it can be seen that a higher quality MOF can in some cases be synthesized by performing the reaction in a nitrogen atmosphere. Furthermore, comparing Examples 36 and 37 in Table 1, it can be seen that a higher quality MOF can in some cases be synthesized by performing the reaction in an oxygen atmosphere. In this way, by carrying out the reaction in a closed system as needed, it becomes possible to synthesize a wider range of MOFs.
