Porous Eu - manganese coordination polymer material preparation method and application

A porous Europium - preparation and their use manganese coordination polymer, which is complex following chemical formula: [Eu (CAM) (HCAM) 2Mn2 (H2O) 7] · 7H2O, which were de-CAM and HCAM to the removal of three hydrogen ions and pyridin-4-hydroxy-2,6-diacid two hydrogen ions. The preparation of coordination polymers are: the Eu (NO3) 3 · 6H2O pyridine with 4-hydroxy-2,6-diacid molar ratio of 1: 3 mixture was added in DEF, 72h at 90 ° C to give a reaction complex : Eu (H2CAM) 3 · 5H2O; the Eu (H2CAM) 3 · 5H2O · 4H2O and 1 molar ratio of MnCl2: 3 mixture, added to water 120 ° C for 72h the reaction; and then cooled by the program, filtered and allowed to stand, washed with water The product obtained. The coordination polymer comprises a one-dimensional channel, having a good separation of the mixture of methanol and ethanol at normal temperature and pressure, and has good cycle performance. The coordination polymer can be activated without separation of fatty compounds, and have good cycle performance at normal temperature and pressure. The coordination polymer has important significance in the study of the mechanism of separation and preparation materials.
