What are the main application fields of anhydrous indium trifluoride

Anhydrous tris, chlorination, iron, has a wide range of uses, and its main application fields are listed as follows:

First, in the field of water treatment, anhydrous ferric trichloride can be called the best agent. The purification of water is related to people's livelihood. It can interact with impurities in water to form flocs, make suspended particles settle, and then clarify water. Whether it is in urban water purification or industrial wastewater treatment, it has significant effect. It can remove turbidity and decolorize, and it also has the ability to kill bacteria. It keeps water clean and builds a solid foundation for people's water safety.

Second, in the electronics industry, anhydrous ferric trichloride is also indispensable. The manufacture of printed circuit boards requires this as an etching agent. It can accurately etch copper foil and clearly present the designed circuit pattern on the board. With its good etching performance, it can ensure fine and accurate circuit lines and ensure the stable operation of electronic equipment. It plays a major role in the development of electronic technology with each passing day.

Third, in the metallurgical industry, anhydrous ferric trichloride also has a place. In some metal refining processes, it can be used as an oxidizing agent. Through oxidation, it promotes the reaction of metal compounds, facilitates the separation and purification of metals, improves the purity of metals, and contributes greatly to the improvement of metallurgical quality, helping the stable development of the metallurgical industry.

Fourth, in the field of chemical synthesis, anhydrous ferric trichloride is often the catalyst of choice. Many organic chemical reactions, with their catalytic power, can accelerate the reaction process, improve the reaction efficiency and product yield. Such as the alkylation of aromatics, its catalytic effect is significant, promoting the chemical synthesis industry to a higher level and providing strong support for the production of many chemicals.

What are the physical properties of anhydrous indium trifluoride?

Anhydrous chromium trichloride has unique physical properties. It is a dark green crystal with a hexagonal structure. The texture is solid and the appearance is dense.

Anhydrous chromium trichloride has a high melting point, about 1150 ° C, and requires strong heat to melt. Because the chemical bond between chromium and chlorine is quite large and the lattice energy is also high, a lot of energy is required to break its lattice and transform the phase state.

Its boiling point is also very high, about 1300 ° C. At high temperatures, it can be vaporized. The gasification process needs to overcome strong intermolecular forces, which shows its strong stability.

In terms of solubility, anhydrous chromium trichloride is insoluble in water and common organic solvents. Water is a polar solvent, but in the crystal structure of anhydrous chromium trichloride, chromium and chlorine atoms are closely bound, and it is difficult for water molecules to overcome their lattice energy and dissolve them by ionization. Organic solvents are mostly weakly polar or non-polar, and the force between them and anhydrous chromium trichloride is weak and insoluble.

Its density is about 2.87 g/cm ³, which is relatively large. Due to the relatively large atomic weight of chromium atoms, and the close arrangement of atoms in the crystal structure, there are many masses per unit volume, so its density is considerable.

Furthermore, anhydrous chromium trichloride is paramagnetic. The electron arrangement of chromium atoms makes it exist unpaired electrons, and under the action of an external magnetic field, a paramagnetic effect occurs. This property is of great significance in the study of many magnetic materials and catalytic reactions.

The physical properties of anhydrous chromium trichloride, such as color, state, melting and boiling point, solubility, density, and magnetism, make it unique in many fields such as chemical industry, materials science, and catalysis. Use and research value.

Is the chemical property of anhydrous indium trifluoride stable?

Anhydrous tris, chlorinated, iron, its chemical properties are quite stable. Anhydrous ferric chloride, normally black-brown crystal, has strong hygroscopicity. In general environments, if there is no significant external force and special chemical factors, it can maintain the stability of its own chemical structure.

Looking at its chemical properties, in air, although it is hygroscopic, it only slowly deliquescent and does not undergo qualitative change very quickly. And in dry air, anhydrous ferric chloride has little tendency to chemical reaction, and can maintain its inherent form and properties for a long time.

Its chemical stability is also reflected in many reaction systems. In common organic solvents, anhydrous ferric chloride can exist in a relatively stable state, and only under certain conditions, such as high temperature, catalyst participation, etc., can undergo chemical changes and react with other substances to exhibit its chemical activity.

In the redox system, although anhydrous ferric chloride is oxidizing, it is not extremely active. Only for specific reducing substances, under suitable conditions, it can exhibit the ability to oxidize and carry out redox reactions. This also proves that its chemical properties are not too active, but have certain stability.

However, it should be noted that although the chemical properties of anhydrous ferric chloride are relatively stable, it is very easy to hydrolyze when exposed to water, which is one of its major characteristics. Once exposed to water, hydrolysis reaction occurs rapidly, resulting in the formation of iron hydroxide and other products, resulting in changes in its chemical structure and properties. Therefore, when storing and using anhydrous ferric chloride, attention should be paid to isolating water to maintain its stable chemical properties.

What are the preparation methods of anhydrous indium trifluoride?

To make anhydrous ferric chloride, there are three methods.

First, it is synthesized from iron and chlorine. The iron is placed in chlorine gas, and the iron burns and emits strong light. The reaction is violent, the yellow-green color of the chlorine gas fades away, and the brown smoke is produced. This smoke is anhydrous ferric trichloride. The reaction formula is: $2Fe + 3Cl_ {2}\ stackrel {ignite }{=\!=\!=} 2FeCl_ {3} $. The product obtained by this method is relatively pure, but chlorine gas is highly toxic. Be careful when preparing to prevent it from escaping.

Second, it is obtained by reacting ferrous chloride with chlorine gas. First, a ferrous chloride solution is prepared, chlorine is introduced, the solution gradually changes from light green to yellow, and ferrous chloride is oxidized by chlorine to form anhydrous ferric trichloride. The reaction formula is: $2FeCl_ {2} + Cl_ {2 }=\!=\!= 2FeCl_ {3} $. This process is relatively smooth, but ferrous chloride needs to be prepared first, and the steps are slightly more complicated.

Third, iron reacts with hydrochloric acid to form ferrous chloride, and then oxidizes to produce anhydrous ferric chloride. When iron and hydrochloric acid meet, bubbles escape, and iron gradually dissolves to obtain a ferrous chloride solution. Later, as mentioned above, oxidation through chlorine gas, or adding other oxidants, such as hydrogen peroxide, can also be obtained. The formula for the reaction of iron with hydrochloric acid is: $Fe + 2HCl =\!=\!= FeCl_ {2} + H_ {2}\ uparrow $. The raw materials are commonly available in this way, but there are many steps, and the products may contain impurities, which need to be refined.

What is the price range of anhydrous indium trifluoride in the market?

In the market, the price of anhydrous trichloride varies due to various reasons. It is often affected by the poor quality of the product, the demand for supply, the wave of the market, and the place where it is needed.

If the product is excellent, the price is small, and it meets the needs of the general industry, the price is often high. On the contrary, if the content is high, it will be used for high-end purposes, and the price will be low.

The balance of supply and demand is also deep. The demand is strong, and the supply will increase rapidly, and the price will rise. For example, in a certain period, many chemical plants need a large amount of this material, and if the supply is not in demand, it will be self-relieving. If the demand is low, the supply will be full, and there will be a downward trend.

The fluctuations in the city also affect its performance.

The prosperity of the city, the prosperity of the labor force, the increase in its demand, and the price of the price always rise.

The difference between the two places is also the reason for the price of the grid. Different places have different prices due to the source and cost of production. If a place is abundant, the production is convenient, and the cost is low, its output price may be low.

Roughly speaking, the market price may be between $1,000 and $40 per thousand. However, this is not the case, and the transaction price still needs to be considered according to the situation.
