Diisobutyronitrile, also known as initiator AIBN, is an organic compound. Its main uses are as follows:
First, it acts as an initiator in the polymerization reaction. For example, in the preparation of polyacrylonitrile, diisobutyronitrile can produce free radicals, which promote the free radical polymerization of acrylonitrile monomers to form polyacrylonitrile. In this process, diisobutyronitrile is thermally decomposed into free radicals, which act as a "fuse" for chemical reactions, initiating a chain reaction between monomers to achieve polymerization. Like the common acrylic fiber, it is prepared by this reaction.
Second, it is used in the field of organic synthesis. In some reactions that require the introduction of specific groups, the free radicals produced by diisobutyronitrile can react with the substrate molecules and introduce corresponding groups. For example, in the preparation of certain organic compounds with special structures, diisobutyronitrile can be used to initiate free radical reactions, build carbon-carbon bonds or other chemical bonds, and achieve the synthesis of the target product.
Third, it also plays a role in the preparation of foam plastics. In the preparation of polyurethane foam and other processes, the free radicals generated by the decomposition of diisobutyronitrile can participate in the decomposition reaction of the foaming agent, releasing gas, so that many tiny pores are formed inside the plastic matrix, which in turn shapes the foam-like structure and imparts good thermal insulation and cushioning properties to the foam.
Fourth, it can also play a role in rubber vulcanization. It can initiate cross-linking reactions between rubber molecules, enhance the physical properties of rubber, such as improving the strength, wear resistance, and aging resistance of rubber, making rubber products more durable and suitable for a variety of different use scenarios.

Diisobutyronitrile is also an organic compound. Its physical properties are quite unique.
Looking at its appearance, it is normally white crystalline, just like winter frost and snow, pure and delicate, in a powder or granular state, giving people a dry feeling.
When talking about the melting point, it is about 102 ° C. When heated, the temperature will be like melting snow and melting, from solid to liquid. This property can be used as a key reference for accurate temperature control in many chemical reactions and industrial processes.
Its solubility also has characteristics, and it can find a place in many organic solvents, such as acetone, ether, benzene, etc., which can be fused with it, just like fish get water. This characteristic paves a broad path for its application in chemical synthesis and other fields, and can be used as a good reaction medium or solvent.
However, its density is also a physical property that cannot be ignored. The value of this density determines its distribution when different substances are mixed, and has a potential impact on the process and results of related reactions.
Furthermore, diisobutyronitrile is relatively stable under normal temperature and pressure. However, once the environment changes and the temperature, pressure and other conditions exceed a certain range, its stability will be like a big tower, which is prone to change, or cause reaction accidents. These physical properties need to be carefully considered in the process of industrial production, storage and transportation to ensure safety in order to make them play their due role in the chemical industry.

The chemical properties of diisopropylamine are still stable under the normal state. However, if it is in special circumstances, it is a different matter.
At room temperature and pressure, diisopropylamine is a colorless liquid with a pungent taste unique to amines. In its chemical structure, nitrogen atoms carry a lone pair of electrons, making it alkaline. This alkaline property allows diisopropylamine to react with acids to produce corresponding salts. For example, in the case of hydrochloric acid, it is converted into diisopropylamine hydrochloride.
However, its stability is not absolute. If exposed to open fire and hot topic, diisopropylamine will appear active. Because of its flammability, fire or hot topic, there is a risk of fire or explosion. This is because of the hydrocarbon elements in the molecule, under suitable conditions, it can react violently with oxygen, put a lot of heat, and cause combustion and even explosion.
And diisopropylamine can react violently with oxidizing agents. Oxidizing agents have the power to seize electrons, while some atoms in diisopropylamine molecules can lose electrons. When the two meet, the reaction is very easy or dangerous.
In addition, in the environment where moisture exists, diisopropylamine may undergo hydrolysis. Although the degree of hydrolysis may be limited, it may affect its chemical properties and purity over time. When hydrolyzed, the molecular structure may change to form a different product.
To sum up, the chemical properties of diisopropylamine can be said to be stable under normal conditions. However, under special circumstances such as high temperature, open flame, oxidant, moisture, etc., its stability is broken, or it may cause various chemical reactions, or cause dangerous states. Those who use it must not ignore its properties, and handle it carefully, so that they can be safe.

For diisobutyronitrile, there are many things to pay attention to during storage and transportation.
In terms of storage, the first thing to do is to choose a cool and well-ventilated place. This is because it is easily decomposed by heat, and under high temperature, it is dangerous. The temperature of the warehouse should be controlled within a suitable range, and it must not be too high. And it must be kept away from fire and heat sources to prevent accidents. Because it is flammable, it is likely to react violently in case of open flame or hot topic.
Furthermore, it should be stored in isolation from oxidants, acids, bases, etc. The chemical properties of diisobutyronitrile cover are active, and contact with them may cause chemical reactions, causing potential safety hazards. The storage place should also be equipped with suitable materials to contain the leakage, in case of leakage, and can be properly handled in time to prevent its spread from causing greater harm.
As for the transportation, it is necessary to strictly abide by the relevant regulations. The transportation vehicle should ensure that the vehicle is in good condition and has corresponding safety protection facilities. The loading process must be light and light, and must not be operated brutally to prevent damage to the packaging. During transportation, the condition of the goods should be regularly inspected, and if there is any abnormality, it should be disposed of immediately.
The escort personnel must also be familiar with the characteristics of diisobutyronitrile and emergency treatment methods. In case of leakage, the surrounding people should be quickly evacuated, the scene should be isolated, and the fire should be strictly prohibited from approaching. At the same time, effective measures should be taken as soon as possible to collect and clean up the leakage, and In this way, it is necessary to ensure that diisobutyronitrile is safe during storage and transportation, to avoid disasters, and to ensure the safety of people and things.

Diisobutyronitrile is also a chemical substance. It has an impact on the environment and human health.
In the impact of the environment, if diisobutyronitrile is released in the atmosphere, because it is volatile, it can participate in photochemical reactions, disturb the chemical balance of the atmosphere, or form one of the causes of photochemical smog. And it is insoluble in water. If it enters the water body, it can sink in the bottom mud, causing sediment pollution and endangering the habitat and reproduction of aquatic organisms. In the soil, or adsorption accumulation, inhibits the activity of soil microorganisms, and disrupts the balance of the soil ecosystem.
As for the impact on human health, diisobutyronitrile is toxic. Entering the body through the respiratory tract can stimulate the respiratory tract, causing cough, asthma, and breathing difficulties. If it comes into contact with the skin, it can cause skin allergies, redness, swelling, and itching. If eaten by mistake, it can damage the digestive system, causing nausea, vomiting, and abdominal pain. Long-term exposure to this substance may increase the risk of cancer because it contains ingredients that can cause genetic mutation.
Therefore, the use and disposal of diisobutyronitrile should be treated with caution. Strict safety procedures must be followed to prevent its leakage and protect the environment and human health. Those who make this substance must not ignore its harm and deal with it properly.
