What are the physical properties of 4-chloro-1,2-benzenediamine?
4-Chloro-1,2-phenylenediamine, its physical properties are as follows:
This substance is usually solid at room temperature, and it may be crystalline in appearance. Its color is white or nearly white. This color is characterized by purity. The melting point is about 108 to 112 degrees Celsius. When it reaches this temperature, the solid gradually melts and becomes a liquid. The boiling point is quite high, about 280 degrees Celsius. At this high temperature, the liquid turns into gas.
4-chloro-1,2-phenylenediamine is difficult to dissolve in water. In water, it sinks more in the bottom and is less mixed with water. However, it has good solubility in organic solvents, such as ethanol, ether, etc., and can be mixed with it. This is because its molecular structure is in agreement with the molecular structure of organic solvents, so it can dissolve.
Its density is greater than that of water, and it will sink but not float when thrown into water. Because the density of a substance is related to the tightness of its molecular arrangement, 4-chloro-1,2-phenylenediamine molecules are closely arranged, so the density is high.
In addition, 4-chloro-1,2-phenylenediamine is relatively stable in air, and it will also chemically change under extreme conditions such as strong oxidants or high temperatures. Due to the fact that the chlorine atom in the molecule is connected to the benzene ring and the amino group, this structure imparts a certain chemical activity to it. However, under normal circumstances, the change is not significant, and the physical properties are relatively stable, allowing it to be preserved for a long time without major differences.

What are the chemical properties of 4-chloro-1,2-benzenediamine
4-Chloro-1,2-phenylenediamine is an organic compound with unique chemical properties. First, it is alkaline, because its amino group can bind protons. This property allows it to form salts in acidic environments, and it can be used as a base in organic synthesis to participate in reactions, like catalyzing certain condensation reactions. Second, it is nucleophilic, and the amino nitrogen atom contains lone pairs of electrons, which can attack electrophilic reagents. In many organic reactions, such as nucleophilic substitution with halogenated hydrocarbons, amino nitrogen attacks the carbon atoms of halogenated hydrocarbons, and the halogen atoms leave to form new carbon-nitrogen bond compounds. Third, it is easy to oxidize, the amino group is active, and it is easily oxidized when exposed to oxidants. If left in the air for a long time, the amino group may be oxidized by oxygen, causing color and chemical properties to change. It is necessary to pay attention to its effect on the reaction during synthesis. Fourth, it has substitution reactivity, and the hydrogen atom on the benzene ring can be replaced by other groups under suitable conditions. Due to the electron giving of the amino group, the electron cloud density of the benzene ring increases, and electrophilic substitution reactions are prone to occur. Substituents can be introduced at specific positions in the benzene ring in reactions such as halogenation, nitrification, and sulfonation. In short, the chemical properties of 4-chloro-1,2-phenylenediamine make it widely used in organic synthesis, materials science, etc. However, due to its potential toxicity and reactivity, it must be handled with caution and properly protected
What are the precautions for 4-chloro-1,2-benzenediamine in the production process?
4-Chloro-1,2-phenylenediamine requires many matters to be paid attention to during production.
The first is related to the selection and purification of raw materials. The purity of raw materials has a great impact on the quality of the product. It is necessary to select high-purity starting materials and remove impurities to prevent impurities from triggering side reactions during the reaction process, resulting in impure products.
Second, the control of reaction conditions is crucial. In terms of temperature, it must be strictly maintained in a suitable range. If the temperature is too high, the reaction may be too violent and many by-products will be generated; if the temperature is too low, the reaction rate will be slow, time-consuming and the yield will not be high. The pressure cannot be ignored. The appropriate pressure helps the reaction to proceed in the desired direction, and the specific reaction can be achieved under a specific pressure. At the same time, the reaction time also needs to be precisely controlled. If it is too short, the reaction will not be completed, and if it is too long, it may cause subsequent side reactions.
Furthermore, safety protection should not be underestimated. 4-Chloro-1,2-phenylenediamine may have certain toxicity and irritation. The production site should be well ventilated. Operators must wear protective clothing, protective gloves and masks to prevent direct contact with the human body and inhalation, which will damage health.
Again, the separation and purification of the product is also key. After the reaction is completed, suitable separation methods, such as crystallization, distillation, extraction, etc., must be used to separate and purify the product from the reaction system to achieve the required purity standards.
In addition, the maintenance and cleaning of production equipment is also very important. Regularly check the equipment to ensure its normal operation, no leakage and other conditions, and after each production, thoroughly clean the equipment to prevent residual substances from affecting the next production.
In short, the production process of 4-chloro-1,2-phenylenediamine is complicated and closely connected. Only by treating each step carefully can we ensure the smooth progress of production and the excellent quality of the product.

What is the market price range for 4-chloro-1,2-benzenediamine?
4-Chloro-1,2-phenylenediamine, its market price range will fluctuate due to a variety of factors, and it is difficult to generalize.
First, the price of raw materials, if the price of raw materials required to synthesize this compound rises, such as the price fluctuations of related halogenated and amine raw materials due to production, market supply and demand, etc., will lead to changes in the cost of 4-chloro-1,2-phenylenediamine, which in turn will affect the price.
Second, the simplicity of the preparation process is also the key. Processes that are complex and require high-end equipment and harsh reaction conditions must have high costs and high prices; conversely, simple process products may have low costs and competitive prices.
Third, the market supply and demand situation determines the price. If many industries, such as dyes, pharmaceutical intermediates manufacturing, have strong demand for them, but limited supply, the price will rise; if the demand is weak, the supply is excessive, and the price may drop.
Fourth, product purity and quality grade have a great impact. High purity and high quality are mostly used in high-end fields, and the price is higher than that of ordinary purity.
In the current market, industrial-grade ordinary purity 4-chloro-1,2-phenylenediamine, the price per kilogram may range from tens of yuan to hundreds of yuan; if it is a high-purity, pharmaceutical-grade product, the price per kilogram may exceed hundreds of yuan, or even higher, but this is only a rough guess, the actual price should be based on real-time market conditions.
