8-Hydroxyquinoline copper is a common organometallic compound. Its physical and chemical properties are quite characteristic, let me tell you in detail.
First, the appearance, this compound is often green to dark green crystalline powder, the appearance of deep color, quite textured. Its properties are quite stable under normal temperature and pressure, and when it encounters hot topics, it needs to be paid attention to, because it may decompose.
Besides solubility, 8-hydroxyquinoline copper is insoluble in water, which makes it difficult to disperse in a water environment. However, it exhibits different states in some organic solvents, such as slightly soluble in alcohols, ethers and other organic solvents, which may affect its application in different media.
When it comes to melting point, its melting point is relatively high, which indicates that its structure is relatively stable and requires a higher temperature to change its lattice structure. This property makes it particularly critical to control temperature during related processing and use.
In addition, 8-hydroxyquinoline copper has certain chemical activity. Because its molecular structure contains both hydroxyl groups and quinoline rings, and it is combined with copper ions, it can play a unique role in some chemical reactions. For example, in a specific catalytic reaction system, it may be able to affect the process and direction of the reaction by virtue of its special structure and activity check point.
And because of its copper-containing elements, under some specific environments, it may participate in the oxidation-reduction reaction. The change of the valence state of copper ions can lead to the change of the properties of the whole compound, and then show different uses in many fields such as materials science and chemical synthesis.

8-Hydroxyquinoline (CU (II) Salt) is prepared by various methods, one of which is described here.
First take an appropriate amount of 8-hydroxyquinoline, dissolve it in a suitable organic solvent such as ethanol, stir to disperse it evenly, and obtain a clear solution. Another salt containing copper (II), such as copper sulfate, is also dissolved in an appropriate amount of water to make a copper salt solution. Under stirring, slowly drop the copper salt solution into the ethanol solution of 8-hydroxyquinoline. During this process, the solution can be seen gradually changing, or there is a gradual precipitation.
The speed of dropwise addition should be slow, and the stirring should not be stopped, so that the two can fully react. When reacting, the temperature should also be paid attention to, and it can usually be maintained near room temperature. However, if you want to control it more accurately, you can set up a constant temperature water bath. After the dropwise addition is completed, continue to stir for a while to make the reaction complete.
After the reaction is completed, the resulting mixed system is separated by filtration. The precipitator is the crude product of 8-hydroxyquinoline copper. Wash the crude product with an appropriate amount of ethanol or other suitable solvent to remove its impurities. After washing, place the precipitate in an oven, control it at an appropriate temperature and time, and let it dry, and finally obtain pure 8-hydroxyquinoline copper. < Br >
When preparing, the purity and dosage ratio of the reagents used, as well as the temperature and time of the reaction, are all related to the purity and yield of the product. Careful operation and precise control are required to obtain high-quality 8-hydroxyquinoline copper.

8-Hydroxyquinoline copper salt needs to be paid attention to when using it. Safety is the first priority. This is the most important. The substance is toxic and can endanger health if it touches the skin, inhales dust or is accidentally ingested. Therefore, when operating, it must be well protected, such as wearing gloves, masks and goggles to prevent its damage.
Furthermore, proper storage is also the key. It should be placed in a dry, cool and well-ventilated place, away from fire and heat sources, to prevent deterioration or cause danger. Because it is sensitive to humidity and temperature, improper environment or performance changes.
When using, precise control of the dosage cannot be ignored. Excessive application, or cause negative effects, in specific application scenarios, or affect the reaction process, or cause damage to the object of action. It must be measured carefully according to specific needs and specified proportions.
Repeat, mixing and dissolving should be done with caution. Different solvents have different solubility, and it is necessary to choose a suitable solvent according to the actual use, and ensure full dissolution and uniform mixing to achieve the best performance.
In addition, during use, the reaction conditions should also be paid close attention to. Temperature, pH and other factors may affect its activity and stability. Strictly control the reaction conditions in order to achieve the desired effect.
In addition, after use, it is also necessary to properly dispose of the residue and waste. Follow relevant environmental regulations and do not discard at will to avoid polluting the environment.
In general, the use of 8-hydroxyquinoline copper salt, safety protection, storage, dosage, mixing and dissolution, reaction conditions control and waste disposal, etc., all need to be treated with caution, and must not be negligent in order to achieve the purpose of safe and effective use.

8-Hydroxyquinoline copper (8-Hydroxyquinoline, CU (II) Salt), which is a common organometallic compound, is used in many fields, such as agriculture as a fungicide, and industry as a preservative in coatings, plastics, etc. However, its market price range is difficult to generalize, because it is subject to many factors.
First, the purity of the product has a great impact on the price. If the purity is very high and there are few impurities, it can meet the strict needs of high-end fine chemicals and other fields, and the price of such products will be high. On the contrary, if the purity is slightly lower, it is only suitable for general and common uses, and the price will decrease. Generally speaking, the price may change significantly every time the purity is increased by a certain percentage.
Second, the market supply and demand relationship is also a key factor. If the market demand for 8-hydroxyquinoline copper is strong, but the supply is relatively insufficient, in case of high season of agricultural pests and diseases, the demand for it as a fungicide increases sharply, and the price is easy to rise. On the contrary, if the market demand is low and the supply is excessive, the price will be under downward pressure.
Third, the production cost also affects the price. The price fluctuation of raw materials and the complexity of the production process are all related to the cost. If the price of raw materials rises, or the production process requires higher technology and equipment input, the cost will increase accordingly.
In terms of the common price range in the market, the price per kilogram may range from tens of yuan to hundreds of yuan in terms of different specifications and purity. Low purity, ordinary specifications, per kilogram or tens of yuan; while high purity, special refining, the price per kilogram can reach hundreds of yuan. However, this is only a rough range, the actual price varies from time to time and place to specific product differences. When purchasing or selling this product, it is necessary to consult relevant suppliers or market surveys in detail to get the exact price.
