What is the production method of Dipotassium 7-Hydroxynaphthalene-1, 3-Disulphonate?

The method of preparing 7-hydroxynaphthalene-1,3-disulfonic acid dipotassium salt requires taking naphthalene as the starting material first. For naphthalene, organic compounds are also based on this, and subsequent reactions can be carried out.
First, the method of sulfonation is used to make the naphthalene co-react with sulfuric acid. This reaction needs to be carried out at a specific temperature and duration to obtain 7-hydroxynaphthalene-1,3-disulfonic acid. During sulfonation, sulfuric acid acts as a sulfonating agent and interacts with the naphthalene molecule to make the sulfonic acid group replace the hydrogen atom at a specific position in the naphthalene ring. The reaction conditions are quite critical. If the temperature is too low, the reaction will be slow and the yield will not be high. If the temperature is too high, there will be side
After obtaining 7-hydroxynaphthalene-1,3-disulfonic acid, the alkali neutralization step is carried out. Mix potassium hydroxide solution with 7-hydroxynaphthalene-1,3-disulfonic acid. As a base, potassium hydroxide neutralizes with the acid, hydroxide ions combine with hydrogen ions to form water, and potassium ions combine with sulfonate ions to form 7-hydroxynaphthalene-1,3-disulfonic acid dipotassium salt. In this step, the amount of potassium hydroxide needs to be precisely controlled. If the amount is insufficient, the neutralization will be incomplete; if the amount is too much, too many impurities may be introduced, which will affect the purity of the product.
After the reaction is completed, it still needs to go through the process of separation and purification. The crystallization method is often used to make 7-hydroxynaphthalene-1,3-disulfonic acid dipotassium salt crystallize from the reaction mixture. By adjusting the temperature, solvent and other conditions, the crystal formation is promoted. Then by filtration, the crystal and the mother liquor are separated. Then the crystals are washed with an appropriate solvent to remove the attached impurities, and finally dried to obtain a pure 7-hydroxynaphthalene-1,3-disulfonic acid dipotassium salt product. In this way, the method for preparing 7-hydroxynaphthalene-1,3-disulfonic acid dipotassium salt.

What is the market price for Dipotassium 7-Hydroxynaphthalene-1, 3-Disulphonate?

What are the safety precautions for Dipotassium 7-Hydroxynaphthalene-1, 3-Disulphonate?

Dipotassium 7-hydroxynaphthalene-1,3-disulfonate, this is a chemical substance. Regarding its safety precautions, it needs to be treated with caution.
First, protective measures must be taken. Because of its risk of irritation to the skin and eyes, when operating, wear protective clothing in front of suitable protective clothing, such as long-sleeved clothing and trousers, and wear protective gloves to protect the skin. At the same time, goggles are also indispensable to prevent them from splashing into the eyes, causing discomfort and even damage.
Second, operate in a well-ventilated place. If this substance forms dust in the air, it may pose a risk of inhalation, and may cause respiratory discomfort after inhalation. Good ventilation can reduce the concentration of this substance in the air and reduce the harm of inhalation. If conditions permit, it is more secure to work in a fume hood.
Third, storage is also exquisite. It should be stored in a dry and cool place, away from fire and heat sources. Due to its nature or affected by temperature, humidity and fire sources, the stability changes and even causes danger. And it should be stored separately from oxidants, acids, etc. to prevent mutual reaction.
Fourth, disposal needs compliance. If there is a spill, do not panic. Small amounts of spills can be collected in a dry, clean, covered container with a clean shovel; large amounts of spills need to be built embankments or excavated for containment, and then disposed of in accordance with relevant regulations. Do not discard them at will to avoid polluting the environment.
