The method of making Copper (II) -8-hydroxyquinoline is described below.
First take an appropriate amount of copper salt, such as copper sulfate, dissolve in water and prepare a solution. This is because copper sulfate is soluble, and copper ions are more active in the solution, which is convenient for subsequent reactions.
Take another 8-hydroxyquinoline and dissolve it in a suitable organic solvent, such as ethanol. Ethanol has good solubility, is relatively safe and easy to obtain.
Take the above 8-hydroxyquinoline ethanol solution and slowly drop it into the copper sulfate aqueous solution. The dripping process needs to be slow and stirred constantly, in order to make the two fully contact and mix evenly, so as to promote the reaction to proceed fully. < Br >
During the reaction, it can be seen that precipitation gradually forms in the solution. This is due to the coordination reaction between Copper (II) and 8-hydroxyquinoline, resulting in the formation of insoluble Copper (II) -8-hydroxyquinoline complex precipitation.
After the precipitation is complete, the precipitation is separated by filtration. The filter paper should be selected with a smaller pore size to ensure that the precipitation is completely intercepted.
The resulting precipitation should be washed several times with ethanol to remove impurities. Ethanol is volatile and new impurities can be avoided. Then the precipitation is placed in an oven and dried at a suitable temperature to remove the residual ethanol and moisture to obtain the product of Copper (II) -8-hydroxyquinoline. Throughout the preparation process, it is necessary to pay attention to the control of reaction conditions, such as temperature, drip acceleration, degree of stirring, etc., in order to obtain a purer product.

When using copper (II) -8 -hydroxyquinoline, all precautions need to be paid attention to in detail. The first priority is safety. This compound may be toxic and irritating. When operating, you must wear protective clothing, gloves and goggles to prevent it from coming into contact with the skin and eyes. If you accidentally touch it, you should immediately rinse it with a lot of water, and seek medical attention according to the severity of the injury.
Furthermore, it may have an impact on the environment. The waste generated during the experiment must not be discarded at will. It must be properly disposed of in accordance with relevant regulations to prevent environmental pollution.
Temperature, pH and other reaction conditions are also crucial. If the temperature is too high or too low, the reaction rate may be abnormal and the product formation may be affected. The change of pH may change the existing form of copper (II) ions and 8-hydroxyquinoline, which in turn affects the coordination reaction of the two. Therefore, it is necessary to precisely control the reaction conditions, with the help of thermometers, pH meters and other instruments, real-time monitoring and timely adjustment.
In addition, the purity of 8-hydroxyquinoline has a great impact on the quality of the product. The presence of impurities may interfere with the reaction, or affect the purity and performance of the product. Therefore, before use, its purity should be carefully checked and purified if necessary.
The weighing and ratio cannot be ignored. Accurately weighing the amount of copper (II) salt and 8-hydroxyquinoline, and reacting according to the established stoichiometric ratio can ensure that the reaction is sufficient and the yield and purity of the product are guaranteed.
The stirring rate is also related to the reaction effect. Appropriate stirring rate can promote the full mixing of the reactants and speed up the reaction process; too fast or too slow rate may have adverse effects on the reaction.

Copper (II) -8-hydroxyquinoline has specific properties and shows its unique ability in various reactions. When it comes into contact with other things, it shows the characteristics of the reaction, which is related to the wonder of coordination.
Covers 8-hydroxyquinoline, which contains coordinated atoms such as nitrogen and oxygen, can coordinate with copper (II) ions. The first reason for this complexation is to form a stable structure.

Furthermore, in the redox environment, copper (II) -8-hydroxyquinoline also has a unique performance. Copper (II) ions change their valence state, and the structure of 8-hydroxyquinoline may also change accordingly. It is either charged or electron-dependent, depending on the surrounding chemical environment.
Under the condition of acid and base, the hydroxyl group of 8-hydroxyquinoline is either protonated or deprotonated, which affects its coordination with copper (II) ions. In a highly acidic environment, the hydroxyl group is easily protonated, or the structure of the complex changes, which affects its reactivity.
And copper (II) -8-hydroxyquinoline has high selectivity to specific substrates compared with other ligands. In case of some functional groups, its complexes may preferentially react with them. This is due to the spatial structure and electronic effects of 8-hydroxyquinoline.
