N% 2C N - What are the main uses of dimethyl dichlorosilane, ethoxy dichlorosilane, methyl trichlorosilane, and phenyl trichlorosilane? Although these four are not detailed in "Tiangong Kaiwu", they are now widely used in the chemical industry.
Dimethyldichlorosilane is a key raw material for the preparation of silicone polymers. After hydrolysis and polymerization, it can form polysiloxane, that is, common silicone oil, silicone rubber, etc. Silicone oil has good lubricity, heat resistance, and chemical stability. It is used as a lubricant, mold release agent, and waterproof agent in machinery, electronics, textiles, and other industries. Silicone rubber has good elasticity, high and low temperature resistance, and aging resistance. It is used in automotive, aviation, medical and other fields to make seals, hoses, artificial organs, etc.
Ethoxy dichlorosilane, which is mostly used to prepare silane coupling agents. This coupling agent can improve the interfacial bonding force between organic materials and inorganic materials. In the manufacture of composite materials, the resin is closely connected with glass fibers, fillers, etc., to improve the mechanical properties and water resistance of the material. In the coating industry, it improves the adhesion of the coating to the substrate and enhances the durability of the coating.
Methyltrichlorosilane, after hydrolysis, methylsilanol can be obtained, and then the methyl silicone resin is synthesized. The resin has excellent heat resistance, insulation and weather resistance. It is often used in high temperature resistant coatings, electrical insulating materials, chemical corrosion resistant coatings, etc., such as protective coatings for high temperature equipment, insulating coatings for electrical and electrical appliances.
Phenyl trichlorosilane, which can be hydrolyzed and condensed to produce phenyl-containing silicone polymers. Because its molecular structure contains phenyl groups, the product has unique properties, such as higher heat resistance, radiation resistance and optical properties. It is mostly used in the preparation of high-end optical materials and radiation-resistant materials. It is indispensable in high-end fields such as aerospace and electronic optical instruments. It is an important raw material for the manufacture of special lenses and optical fiber coatings.

All these substances, due to their unique physical properties, occupy an important position in the process of modern industrial development, and make great contributions to promoting technological progress in various fields.
Is the chemical property of sodium salt of N, N -dimethyldithiocarbamopropyl sulfonate stable?
The substances involved in N% 2CN + - are diaminodiphenylsulfone, p-aminobenzene sulfonamide, sulfadiazine silver and the like. Such chemical substances have stable properties and are related to their use.
diaminodiphenylsulfone, in the structure, the benzene ring is connected to the amino group and the sulfone group. The amino group has the property of giving electrons. Although the sulfone group has the ability to absorb electrons, the two interact to make the molecule as a whole stable. In air, at room temperature, it is not easy to react quickly with common substances such as oxygen. However, in the case of strong oxidants, such as high concentrations of hydrogen peroxide, or high temperatures and oxygen, the amino group can be oxidized, causing structural changes and loss of stability.
p-Aminobenzenesulfonamide, benzene ring, amino group coexist with sulfonamide group. Amino power supply and sulfonamide group also have specific electronic effects. In general environments, this structure is relatively stable. However, in case of strong acid and strong base, the sulfonamide bond can be broken. In strong acid, the amino group is protonated, changing the distribution of electron clouds; under strong base, the hydrolysis of sulfonamide group impairs its stability.
Silver sulfadiazine is the product of the combination of sulfadiazine and silver ions. Silver ions are complexed with a specific group of sulfadiazine. The stability of this complex is quite good, because silver ions interact with organic parts to strengthen the structure. When antibacterial, silver ions are released slowly, while their own structure remains relatively stable. However, in the case of strong reducing agents, silver ions can be reduced to silver elements, causing structural damage and no longer stable.
In short, such chemicals have certain stability in normal and general environments. In case of special chemical reagents, extreme temperatures, acid and base conditions, their stability is easily affected, and the structure may change and the properties are also different.
How to prepare N, N -dimethyldithiocarbamylpropyl sulfonate sodium salt in industrial production
Nowadays, there are genera of N% 2CN + -, namely diaminodiphenylsulfone, p-amino benzene arsonic acid, bismuth hydroxybenzene arsonic acid, etc., which are prepared in industrial production and are quite important. According to the theory of "Tiangong Kaiwu", although this is not directly stated, there are many lessons to be learned from the method of preparation.
To make these substances, the first thing to do is to clarify their physical properties and chemical properties. Diaminodiphenylsulfone has specific properties. When preparing, it is necessary to choose suitable raw materials to promote its reaction in a suitable way. Or you can first take a suitable benzene compound, add other reagents, and make it substitution, condensation and other reactions at the appropriate temperature and pressure. For example, in "Tiangong Kaiwu", it is necessary to check the weather, geographical location, and physical properties. In this preparation, it is also necessary to adjust the degree to make the reaction smooth.
The same is true for the preparation of p-aminobenzarsonic acid. When preparing arsenic sources and amino-containing raw materials, use subtle methods to make the two fit. In the meantime, preventing impurities from mixing and controlling the reaction process are all important tasks. This is similar to the art of metallurgy and pottery in "Tiangong Kaiwu". Only by being good at heat and material control can you get good products.
The preparation of bismuth hydroxybenzarsate, the choice of raw materials, bismuth salt and substances containing hydroxyl groups and arsonic acid groups are appropriate. The method of reaction, either liquid-phase synthesis or solid-phase reaction, depends on its characteristics. During the process, the speed of stirring and the time of reaction are all related to the quality of the product.
All this preparation requires careful and meticulous craftsmen, such as the craftsman spirit advocated in "Tiangong Kaiwu", the careful observation of physical properties, and the precise application of skills, in order to produce high-quality N% 2CN + - products in industrial production to meet all needs.
What is the approximate market price of N, N-dimethyldithiocarbamylpropyl sulfonate sodium salt?
Nowadays, there are genera N% 2CN + -, which are diaminodiphenylsulfone, sodium p-aminobenzarsate, bismuth hydroxyaminobenzarsate, etc. The market price often varies depending on the purity of the quality, the amount, and the time.
For diaminodiphenylsulfone, the price always changes due to the needs of pharmaceuticals and research. If its quality is pure and high standard, the market price is about hundreds of gold to thousands of gold per kilogram. Sodium p-aminobenzarsate is often related to animal husbandry and medicine, and its price also varies according to the supply and demand of the market, roughly hundreds of gold per kilogram. As for bismuth hydroxyaminobenzarsate, because of its use or narrowness, it is related to the pharmaceutical and chemical industry, and its price per kilogram or hundreds of gold.
However, the market is unpredictable, the situation changes, and the price fluctuates, not a word can be determined. The sale of various merchants also has its own price. If you want to know the exact number, you must study the city in detail, and consult the people, and observe the supply and demand of the time before you can get its true price.
