Diphenylphosphonyl benzene-3-sulfonic acid, sodium salt, many precautions need to be paid attention to during storage and transportation.
This compound is quite sensitive to environmental conditions. When storing, choose a dry, cool and well-ventilated place. If the environment is humid, it may change its properties due to moisture absorption, which will affect the quality and utility. Temperature also needs to be carefully controlled. Excessive temperature may cause decomposition and deterioration, so it should be avoided in a high temperature environment.
During transportation, the packaging must be solid and reliable. This substance has certain chemical activity. If the packaging is damaged or reacts with external substances, it will not only endanger the safety of transportation, but also cause the product to fail. And when handling, it should be handled with care to prevent damage to the packaging.
Furthermore, because it is a chemical product, storage and transportation should be kept away from fire sources, heat sources and strong oxidizing agents. Fire sources and heat sources may cause hazards such as combustion and explosion; strong oxidizing agents may come into contact with them, or cause violent chemical reactions, causing unpredictable hazards.
In addition, relevant operators should be familiar with its characteristics and emergency treatment methods. In the event of an unexpected situation such as leakage, they can respond quickly and properly to reduce the harm. In short, in the process of storing and transporting diphenylphosphonyl benzene-3-sulfonic acid and sodium salts, the details of each link are related to safety and quality, and must not be negligent.

The method of making diphenylphosphorylbenzene-3-sulfonic acid and sodium is not detailed in the ancient book "Tiangong Kaiwu", but it can be deduced according to chemical principles and predecessors' methods.
To make this substance, first take diphenyl phosphide as the base. Diphenyl phosphide is often obtained by combining halogenated benzene with phosphide, according to the method of nucleophilic substitution. Halogenated benzene such as bromobenzene, chlorobenzene, phosphates such as phosphorus trichloride, etc., in suitable solvents, such as ethers, or aromatic hydrocarbons, coupled with catalysts, such as metal catalysts, etc., temperature control should be used to obtain diphenyl phosphide.
After obtaining diphenyl phosphide, the sulfonic acid group should be introduced. The introduction of sulfonic acid groups is often by the method of sulfonation. Concentrated sulfuric acid or fuming sulfuric acid is used as the sulfonating agent, and the reactor is co-located with diphenyl phosphide. When sulfonating, the temperature and reaction time must be strictly controlled. If the temperature is too high, it may cause side reactions to clump, and the product is impure; if the time is not appropriate, it is difficult to achieve the expected yield. After the sulfonation reaction is completed, the product is neutralized, and the sulfonic acid group is turned into a sodium salt in a sodium hydroxide solution, then diphenyl phosphorylbenzene-3-sulfonic acid and sodium are obtained.
After separation and purification, such as crystallization and chromatography, impurities are removed to extract the purity of the product, and finally high purity is obtained. Phenylphosphorylbenzene-3

Diphenylphosphonyl benzene-3-sulfonic acid, sodium salt, is a chemical substance. Its safety information is very important, and it is related to the safety of those who use this substance and the protection of the environment.
In terms of toxicity, although there is no detailed toxicity data to conclusively indicate the degree of harm to living beings, there are many latent risks of chemical agents, or they can be caused by oral, skin contact or inhalation. If ingested inadvertently, it may irritate the mouth, throat and stomach, causing discomfort, such as nausea, vomiting, abdominal pain, etc.; skin contact, or cause allergies, redness, swelling, itching; if inhaled its dust or vapor, or irritate the respiratory tract, causing coughing, asthma, breathing difficulties.
In terms of explosive properties, this material is usually relatively stable and not prone to spontaneous combustion and spontaneous explosion. However, in case of hot topics, open flames or strong oxidants, there is also the possibility of reaction, or the generation of harmful gases.
Protective measures are indispensable. When operating, be sure to wear protective clothing, which can prevent this material from coming into contact with the skin, and the material must be chemically resistant. At the same time, wear protective gloves. The material of the gloves should be able to resist the erosion of this material, which can effectively protect the skin of the hands. Furthermore, protective glasses are required to prevent this object from splashing into the eyes and causing damage to the eyes. If you work in a poorly ventilated area, you should also wear a suitable breathing apparatus to filter the dust or steam of this object in the air to ensure the safety of breathing.
If a leak occurs accidentally, immediately isolate the scene and prohibit unrelated people from approaching to prevent them from coming into contact with this object. In the event of a small amount of leakage, a clean shovel can be used to collect it in a dry, clean, covered container; if there is a large amount of leakage, it is necessary to build a dike or dig a pit for containment, and then transfer it to a tanker or a special collector for recycling or transportation to a waste treatment site for proper disposal. Do not discharge at will to avoid polluting the environment.
