Abstract

The invention discloses a method for preparing a porous europium-manganese coordination polymer and an application thereof. The porous europium-manganese coordination polymer is a coordination compound in the following chemical formula: [Eu(CAM)(HCAM)2Mn2(H2O)7].7H2O, wherein CAM and HCAM respectively are obtained from 4-hydroxy-2,6-cinchomeronic acid, from which three hydrogen ions and two hydrogen ions are removed. The preparation method of the coordination polymer comprises the steps of mixing Eu(NO3)3.6H2O with 4-hydroxy-2,6-cinchomeronic acid according to the mol ratio of 1:3 and adding to DEF; reacting for 72 hours at 90 DEG C to obtain the coordination compound, namely Eu(H2CAM)3.5H2O; mixing the Eu(H2CAM)3.5H2O with MnCl2.4H2O according to the mol ratio of 1:3, adding to water to react for 72 hours at 120 DEG C; and cooling, filtering, standing and washing by a program to obtain the product. The coordination polymer contains a one-dimensional duct; the mixture of methanol and ethanol has a good separating effect at normal temperature and normal pressure, and has good cycle performance. The coordination polymer can separate fatty alcohol compounds without activation at normal temperature and normal pressure, and has good cycle performance. The coordination polymer has great significance in the aspects of preparation of separate materials and mechanism research.

Description

technical field [0001] The invention belongs to the technical field of combining inorganic chemistry and material chemistry, and relates to a porous europium-manganese coordination polymer material, in particular to a compound based on europium (III) ions, manganese (II) ions and 4-hydroxyl-2,6- Coordination polymer material constructed with pyridinedioic acid, preparation method and application thereof. Background technique [0002] The synthesis and properties of porous coordination polymers are one of the important research fields in inorganic chemistry and materials chemistry developed in the late 1990s. Since the pore size of coordination polymers with an open pore structure can be adjusted, and the inner wall of the pore can be modified, porous coordination polymers can be used as separation materials to complete the separation of many similar mixtures. In addition, this type of material also has the characteristics of large specific surface area and large pore volum...
