Anthraquinone-2,7-Disulfonic Acid Sodium Salt What are the precautions in the production process

Anthraquinone-2,7-disulfonic acid, sodium salt in the production process, there are several ends should be paid attention to.
First, the purity of the material is crucial. If the raw material is not pure, impurities will enter the product and hinder its quality. Take high-purity anthraquinone as the starting material, carefully process the raw material, and remove the chores to ensure that the subsequent reaction is smooth and the product meets the standard.
Second, the temperature and pH of the reaction must be strictly controlled. This reaction is appropriate in a specific temperature range and pH environment. If the temperature is too high or low, the reaction rate and product selection will be affected, resulting in low yield and increased impurities. With the equipment of precise temperature control and pH adjustment, real-time measurement and adjustment can be used to maintain the best reaction environment.
Furthermore, the stirring should not be ignored. Uniform stirring promotes the material to be fully mixed, the reaction is uniform, and the local reaction is avoided. In the large-volume reactor, a good stirring device is set up to ensure the stirring effect, so that the reaction conditions are similar.
Repeat, the choice of solvent is very heavy. The suitable solvent makes the reactant soluble and promotes the reaction, and the yield and product are pure. Depending on the reactivity and product, the best solvent should be sieved, and its boiling point, solubility, and difficulty in recovery should be considered.
In addition, safety protection should not be taken lightly. Chemicals involved in production may be dangerous, such as rot, poison, etc. Operators wear suitable protective clothing, such as gloves, goggles, and protective clothing. The workshop is equipped with a well-ventilated system to remove harmful gases and reduce risks.
At the end, wastewater treatment is also critical. After the reaction, the wastewater contains pollutants and is directly discharged into the environment. Build a suitable wastewater treatment system, adopt chemical and biological methods, reduce the concentration of pollutants, and discharge after compliance.

What is the market price range for Anthraquinone-2,7-Disulfonic Acid Sodium Salt?

Anthraquinone - 2,7 - Disulfonic Acid Sodium Salt, that is, anthraquinone - 2,7 - disulfonate sodium salt, its market price range often fluctuates due to a variety of factors. This substance is widely used in chemical industry, printing and dyeing, medicine and other fields, and different application scenarios have different requirements for its purity and Quality Standards, which has a great impact on the price.
In the chemical raw material market, if it is an ordinary industrial grade, it is for large-scale basic chemical production. Because of its large demand, relatively mature production process, and relatively close to the people. However, if it is used in medicine, high-end printing and dyeing and other fields, the quality indicators such as purity and impurity content are strictly required, and the production difficulty and cost are high, and the price will rise sharply.
In addition, the market supply and demand relationship also affects its price. If the demand of downstream industries is strong during a certain period of time, and the production supply is limited, in case of shortage of raw materials, equipment failure of production enterprises or policy regulation resulting in a decrease in production capacity, the price will rise; on the contrary, if the market oversupply, enterprises compete for share, and the price may be reduced.

Therefore, the storage place must be dry, and the humidity should be maintained between 40% and 60%.
Third, it should be placed in a sealed container. There are gases such as oxygen and carbon dioxide in the air, which can be contacted for a long time or cause reactions such as oxidation. Sealed storage can block external gas interference and ensure its chemical stability. Containers with good sealing such as glass bottles and plastic bottles can be selected. After use, be sure to seal them in time.
Fourth, keep away from fire sources and strong oxidants. This material may be flammable, and it is easy to cause combustion danger in case of open flames and hot topics. Contact with strong oxidants may trigger violent chemical reactions or even explosions. Therefore, no fire source should be stored in the storage place, and it must be stored separately from strong oxidants.
In this way, proper storage of anthraquinone-2,7-disulfonate disodium salt can ensure that it maintains good quality and performance for a long time to meet the needs of industrial production and scientific research.
