What are the precautions in the production process of 4-amino-1-naphthalenesulfonate sodium hydrate
4-Amino-1-naphthalenesulfonic acid copper ammonia complex in the production process, there are several ends that should be paid attention to.
The quality of the first raw materials. To obtain the best quality product, the purity and characteristics of the raw materials used are essential. 4-Amino-1-naphthalenesulfonic acid and copper salts and other raw materials, the impurity content should be strictly controlled. If there are too many impurities, or the reaction is skewed, the product is impure, and the product is affected. If high purity 4-amino-1-naphthalenesulfonic acid is used, it can avoid the side reactions caused by impurities and ensure the uniform quality of the product.
The second time is the reaction condition. Temperature has a great effect on the reaction. If the temperature is too low, the reaction rate will be slow and time-consuming; if the temperature is too high, it may cause side reactions to produce, and the product will decompose or convert into other substances. Therefore, the temperature must be precisely controlled according to the reaction characteristics. If controlled in a specific temperature range, the reaction will be fast and accurate. The pH value is also critical. The formation of this complex requires a suitable pH environment. Peracid or alkali can disturb the equilibrium of the reaction, or hinder the formation of the complex. The pH value of the system should be stabilized by methods such as buffers.
Furthermore, stirring should not be ignored. Stirring can promote the mixing of raw materials and make the reaction uniform. Good stirring can avoid uneven local concentration and cause different reactions. If there is insufficient stirring, or there is accumulation of raw materials, the reaction is not complete and the product is uneven.
After and safety protection. Hazardous chemicals may be involved in production, such as copper salts, etc. During operation, follow safety regulations and wear protective clothing, such as gloves, goggles, etc., to avoid contact with the human body. Waste gas and waste liquid must also be properly disposed of, and in accordance with environmental regulations, harmless treatment should be carried out to prevent pollution of the environment.
In summary, in the production of 4-amino-1-naphthalenesulfonic acid copper-ammonia complex, raw materials, reaction conditions, stirring and safety protection must be carefully handled to ensure that production is smooth and high-quality products can be obtained.
What is the market price range of 4-amino-1-naphthalenesulfonate sodium hydrate?
In today's market, the quality of the aqueous solution of 4-amino-1-naphthalenesulfonic acid, due to various reasons, is involved. The quality of the product depends on many factors, such as the quality of the land, the quality of the land, the supply and demand of the land, and the ease of manufacturing.
If the land is well-made and comes from a famous place, its quality or high. Because of the correct materials used, the exquisite workmanship, and the excellent performance of the product, it is suitable for general industrial purposes, such as dyeing, dyeing, etc., and is affected by the green. For those of this high quality, the price per location is low, or up to ten gold.
If the land is slightly damaged, or the land is normal, and the supply is not suitable for demand, the price will drop. However, it is not necessary to use it, and it can also be used in some cases where the requirements are not high. Such common products, or gold per bit.
The problem of supply and demand also depends on factors. If there is a shortage of demand, the supply will be insufficient, and the demand will be reduced. On the contrary, if the production is prosperous, the demand will be depressed, and the demand will decline.
Furthermore, the ease of creation also has implications. If the method of manufacturing is complex, rare materials are required, and the cost is high and the cost is low; if the method is easy, the materials used are often low, and the cost is easy to level.
Generally speaking, the market value of 4-amino-1-naphthalenesulfonic acid aqueous solution is low, low or low, high or high, and the difference is due to the above reasons.
What are the storage conditions for 4-amino-1-naphthalenesulfonate sodium salt hydrate?
4-Amino-1-naphthalenesulfonate cobalt-ammonia aqueous solution compound, its storage conditions are very important. This compound is delicate and susceptible to external disturbance and change its properties.
First, it is better to hide in a cool place. If it is in a high temperature place, its molecular thermodynamics will intensify, or cause structural changes, losing its inherent properties. For example, when exposed to the hot sun in summer, its decomposition rate will increase sharply, and its efficacy or its chemical activity will be damaged. Therefore, in the room where it is stored, the temperature should be controlled below 20 degrees Celsius to ensure its stability.
Second, when avoiding humid environments. This compound has hygroscopicity and is easy to deliquescent when wet. Water molecules enter its lattice, or change its chemical environment to promote its chemical reaction and cause qualitative change. Where it is stored, the humidity must be strictly controlled, preferably below 50%, and desiccant can be used to supplement it to prevent moisture from invading.
Third, it is also important to avoid light. Light contains energy, which can stimulate the molecules of this compound and cause photochemical reactions. If exposed to strong light, it may change color and decompose. Therefore, it should be stored in an opaque container and hidden in a dark place, so as not to be disturbed by light.
Fourth, it should be stored separately and not mixed with other things. This compound may react with other chemicals and cause deterioration. Such as acids, alkalis, etc., when they meet, they will chemically change and damage their composition. Therefore, when storing, you must be careful, separate them and keep them pure.
In this way, the 4-amino-1-naphthalenesulfonic acid cobalt-ammonia aqueous solution can be properly stored in a cool, dry, dark, and solitary method to keep its quality constant for later use.
