What is the main use of 3,4-dichlorobenzaldehyde?
Dioxo isobutyronitrile, that is, 2,2 '-azobisisobutyronitrile (AIBN), its main uses are as follows:
AIBN is an extremely important initiator in organic synthesis. In radical polymerization, free radicals can be homogenized at appropriate temperatures to form free radicals, which can initiate the polymerization of alkenyl monomers, such as styrene and acrylates, to obtain various polymer. For example, in the preparation of polystyrene, AIBN decomposes free radicals, prompts styrene monomers to connect with each other to grow chain macromolecules, and finally forms polystyrene resins, which are widely used in plastics, packaging materials and other fields.
It is also commonly used to prepare graft copolymers. By generating free radicals, AIBN can connect the main chain of one polymer to the branched chain of another monomer, which can give the polymer new properties. For example, in some rubber modifications, graft polymerization allows the rubber to form graft copolymers with other monomers to improve the strength and wear resistance of the rubber.
In the field of organic synthesis, AIBN can be used to initiate some special radical reactions. For example, it can prompt halogenated hydrocarbons to produce carbon radicals, which in turn undergo addition reactions with other unsaturated compounds. This reaction provides an effective way to build carbon-carbon bonds and helps to synthesize complex organic compounds.
AIBN also plays a role as a blowing agent in the preparation of foam plastics. During the polymerization process, it decomposes to produce gases such as nitrogen, which form bubbles in the polymer system, causing the polymer to foam, eventually resulting in foam products, such as common polyurethane foam.

What are the physical properties of 3,4-dichlorobenzaldehyde
Dioxybutane, also known as 1,4-dioxane, is a common organic compound. Its physical properties are as follows:
From the perspective of dioxybutane, it is a colorless and transparent liquid. It is like clear water, refracting a soft luster under sunlight, pure and free of impurities. Smell it, it has a slightly sweet and ether-like special smell. Although this smell is not pungent, it cannot be smelled for a long time.
When it comes to volatility, it is highly volatile. After opening the lid, it is quickly emitted in the air, like a light spirit, which disappears in an instant. This characteristic requires special attention during operation to prevent its volatilization and dissipation.
Solubility is an absolute, dioxybutane can be miscible with water and many organic solvents such as ethanol and ether in any ratio. Like a friendly significant other, it can get along well with many substances. This excellent solubility makes it often used as an excellent solvent in chemical production, helping various chemical reactions to proceed smoothly.
The melting point is about 11.8 ° C. Under this temperature, dioxybutane will gradually change from liquid to solid, just like smart water condenses into crystal clear ice. And its boiling point is 101.3 ° C. When heated to this temperature, dioxybutane is like a butterfly of feathers, sublimating from liquid to gas and rising.
In terms of density, its relative density (water = 1) is about 1.03, which is slightly heavier than water. If the two are placed in one place, dioxybutane will quietly sink to the bottom of the water, like a stable stone.
Dioxybutane vapors are heavier than air, which means that its vapors can easily accumulate in low places, forming a potential hazard. The operating site must be well ventilated to prevent the accumulation of vapors from causing safety hazards.

Is the chemical property of 3,4-dichlorobenzaldehyde stable?
3% 2C4-dioxanone, that is, 1,4-dioxane2-one, has relatively stable chemical properties.
Structurally, the compound has a cyclic lactone structure. The existence of the lactone ring gives it a certain stability. Generally speaking, compared with the chain structure, the cyclic structure has unique properties due to the tension of the ring and the interaction between atoms. In 3% 2C4-dioxanone, the carbonyl group (C = O) in the lactone ring has a certain reactivity, but its reactivity is not very high due to the conjugation effect of the ring and the steric resistance and other factors.
Under common chemical reaction conditions, 3% 2C4-dioxanone is not prone to spontaneous decomposition or other violent reactions. For example, in normal temperature and pressure, neutral environment, it can maintain a stable chemical state for a long time. However, under some specific conditions, such as high temperature, strong acid and base, or the presence of specific catalysts, the lactone ring may undergo a ring-opening reaction. Under basic conditions, hydroxide ions will attack the carbonyl carbon on the lactone ring, causing the ring to rupture, and then a series of hydrolysis and other reactions will occur. Under acidic conditions, protonated carbonyl groups will enhance their electrophilicity and may also trigger ring-opening reactions. However, in general, 3% 2C4-dioxanone exhibited good chemical stability in a milder and more conventional environment.

What is the production method of 3,4-dichlorobenzaldehyde?
The method of dimethyl ether requires methanol, formaldehyde and other raw materials to be reversed.
In this method, methanol is first placed in the kettle, followed by an amount of catalysis, and then added to boil. When the methanol is purified, it is added to the reactor containing formaldehyde. The two are combined and reversed at a specific temperature and temperature.
In the case of reaction, the degree of control, the proportion of raw materials, and the ratio of raw materials. The degree of resistance is high, the side reaction is low, and the reaction rate is not high. The same is true. The appropriate solution can promote the reaction.
The reaction is low, and the mixed product is obtained. In the method of refining, it is necessary to separate and extract the raw materials, by-products, etc. that have not been reversed, so as to obtain two-thirds of the methyl ether.
There are other methods, but as mentioned in "Tiangong Products", this method is often used. The operation is careful, and follow the procedure to ensure safety and obtain good products.

What are the precautions for storing and transporting 3,4-dichlorobenzaldehyde?
3% 2C4-dioxofuran formaldehyde needs careful attention during storage and transportation.
When storing, the first ambient temperature. This substance should be stored in a cool place. If the temperature is too high, it is easy to change its properties, or cause adverse conditions such as decomposition, which will damage the quality. For example, in hot summer, if there is no suitable temperature control, its stability will be difficult to guarantee.
Humidity is also the key. Humid environments can cause 3% 2C4-dioxofuran formaldehyde to become damp or react with water vapor, which in turn affects its purity and performance. Therefore, the storage place must be kept dry, and the environment can be maintained dry by auxiliary means such as desiccants.
Furthermore, it should be avoided from excessive contact with air. Due to its certain chemical activity, it is exposed to the air for a long time, or reacts with oxygen and other ingredients, resulting in deterioration. Sealed storage is a good policy, which can effectively isolate the air and delay the deterioration process.
During transportation, the packaging must be stable and tight. Because of its certain danger, if the packaging is not good, it will encounter bumps and collisions during transportation, which will easily cause leakage, which will not only endanger the safety of transporters, but also may pollute the environment.
The choice of transportation means should not be underestimated. It is necessary to consider whether it has suitable temperature control and shock-proof conditions to ensure a smooth transportation process and suitable temperature, so that 3% 2C4-dioxyfuran formaldehyde is not damaged due to external factors.
In addition, transport personnel should be familiar with the characteristics of the substance and emergency treatment methods. In the event of an unexpected situation, such as leakage, etc., they can respond quickly and properly to minimize the harm. In this way, the safety and quality of 3% 2C4-dioxyfuranaldehyde during storage and transportation can be ensured.
