What is the main use of 1,5-naphthalene disulfonate disodium salt?

1% 2C5 + - + arsenic, that is, arsenic trioxide, is extremely toxic and rarely used for legitimate purposes. It is more regarded as a poison because of its toxicity. However, in ancient times, there are also very few records of medicinal use.
Arsenic is mentioned in the "Compendium of Materia Medica", which says that it is hot and poisonous. In some ancient medical texts, there were doctors who used arsenic to treat some difficult diseases with extreme caution. For skin diseases such as scabies and scrofula, a small amount of arsenic can be used externally after special processing, and it can be used to fight poison with poison. With its toxicity, it inhibits the bacteria on the surface of the skin and achieves therapeutic effect. It is also used to treat malaria. The ancients believed that it could adjust the imbalance of yin and yang in the human body and relieve malaria to a certain extent.
However, the use of arsenic to treat diseases is extremely risky. If the dosage is not careful, it can cause poisoning, causing severe vomiting, abdominal pain, diarrhea, and even life-threatening. In addition to the development of modern medicine, there are many safer and more effective drugs and therapies, and arsenic has been rarely used in medicine.
In the industrial field, there is no modern use of arsenic. In modern industry, arsenic may be used to make some special glass and alloys, but the ancient industrial technology is limited and there is no such use. Overall, arsenic was mainly used in the field of medical exploration in ancient times, but its application was extremely cautious and rare.

What are the physicochemical properties of 1,5-naphthalene disulfonate disodium salt?

1% 2C5 - Musk diacetal acid dianhydride ketone is a strange medicine, and its physicochemical properties are particularly important.
Musk diacetal acid dianhydride ketone has warm and less dryness. Under normal conditions, it is in a solid state, its color is white or nearly white, the texture is dense and solid, and it has a delicate feeling to touch. The melting point of this medicine is quite high, and it can be melted into a liquid at high temperature, but the gasification temperature is higher, so it is difficult to volatilize.
Its solubility in water is very small, only slightly soluble, just like a pearl in water, difficult to blend with water. However, in organic solvents, it can be better dissolved. In case of alcohols and ether solvents, it is like a fish getting water and can be evenly dispersed in it.
The chemical properties of musk musk diacetate dianhydride ketone also have characteristics. The special functional groups in its structure make it reactive to a certain extent. In case of alkaline substances, reactions such as neutralization can occur, similar to the harmony of yin and yang, resulting in different compounds. In case of strong oxidizing reagents, although they are not easily oxidized, if the conditions are suitable, they will also change and the structure will be changed, which will make the efficacy and properties of the drug different. Its stability is acceptable, and it can be stored for a long time at room temperature and humidity without deterioration. However, if it is placed in a place with high temperature, high humidity or direct light, it may gradually change and the efficacy will be affected. Such various physical and chemical properties need to be carefully considered when they are used in medicine and application.

What are the precautions in the production process of 1,5-naphthalene disulfonate disodium salt?

First, the extraction of raw materials is very important. If there is a large amount of naphthalene, it will affect the quality of the product. It may cause insufficient reaction, or generate by-products, so that the quality of the obtained 1,5-naphthalene disulfonic acid is low. Therefore, the quality, quality and content of the naphthalene must be controlled according to the quality of the material.
Second, the reaction of the product needs to be carefully controlled. The degree and force of reaction can all affect the process of reaction. If the temperature is high, or the reaction speed is high, unnecessary side effects will be generated; if the temperature is low, the reaction rate will be slow, and the production efficiency will be greatly reduced. The same is true for the force, and it needs to be maintained at the right level to ensure the reaction rate. And the reverse process, also according to the characteristics of the reverse process, the fine judgment is insufficient, and the reaction is not complete; the reverse process, only increase energy consumption, and may lead to side effects.
Third, the reverse medium should not be ignored. Different reverse media, the reaction rate and performance have an impact. The appropriate reverse medium can promote the dissolution and dispersion of the reverse material, making the reaction more uniform and efficient. At the same time, it is also necessary to consider the compatibility of the reverse medium and the reverse material to prevent it from generating unnecessary side effects.
Fourth, it is necessary to separate the preparation steps and complete the processing. After the processing is completed, the obtained materials often contain waste, such as raw materials, side materials, etc. It is necessary to use appropriate separation methods, such as crystallization, extraction, etc., to achieve a high degree of 1,5-naphthalene disulfonic acid disulf. operation, pay attention to the operation procedures of each method, to ensure the effect of the distribution.
Fifth, safety is not allowed. During the production process, or contact with multi-hazardous chemicals, such as sulfuric acid and other corrosive substances. Operators should abide by safety procedures and wear protective equipment, such as eye protection, gloves, gas masks, etc. At the same time, it is also equipped with perfect safety measures, such as installation, fire equipment, etc., to prevent accidents.

What are the storage conditions for 1,5-naphthalene disulfonate disodium salt?

In "Tiangong Kaiwu": "The storage of dithioacid and dithioic acid should be kept in the dark to avoid moisture and heat. Put it in a porcelain dish, and do not use iron and copper utensils. If it encounters iron and copper, it may change. The temperature should be at room temperature. If it is too high, it will damage its performance, and if it is too low, it will not be a good way to survive. The air circulation is good, but it should not be exposed to the wind. In this way, it can be stored for a long time without losing its quality."
