introduction | 8-hydroxyquinoline aluminum is an ideal green luminescent material with good luminescent properties, film-forming properties and thermal stability, and is widely used in organic electroluminescent devices. However, 8-hydroxyquinoline aluminum with a purity greater than 95% can be used as an organic luminescent material. |
preparation | a new method for synthesizing 8-hydroxyquinoline aluminum with short process, low production cost and low pollution: in the first step, the added material is 8-hydroxyquinoline: aluminum formate = 3:1 according to the molar ratio, the reaction raw materials are alternately added into a 100L ball milling tank, and the total amount of 8-hydroxyquinoline is added with 6.438kg, A total of 2.395kg of aluminum formate was added. The grinding ball is agate ball, the mass ratio of grinding ball to material is 15:1, and the mass of agate ball is 132.5kg. In the second step, the ball milling reaction ball milling tank is vacuumized. After the vacuum degree is less than 0.1Pa, the pumping is stopped and ball milling is started. The rotating speed of the ball mill is 150r /min, and the ball milling time is 1.5h to obtain yellow product. In the third step, vacuum drying, the yellow product obtained in the second step is placed in a vacuum dryer, and vacuum dried at 50°C for 2h to obtain 8-hydroxyquinoline aluminum with a purity of 98%. The evacuated gas contains formic acid, which is recovered by condensation. |
use | sublimation stage for organic electronic devices. Used for luminescent materials and electronic transmission materials; as a metal corrosion inhibitor for pesticide and pharmaceutical synthesis |
