1% 2C3-divinylbenzene is an organic compound with the following physical properties:
First, looking at its properties, it is a colorless to slightly yellow transparent liquid under normal conditions, and its color will gradually darken due to polymerization under sunlight. Its odor is unique, with an irritating smell similar to styrene, and it is pungent.
Second, when it comes to boiling point, it is between 195 ° C and 207 ° C. This boiling point characteristic makes it change from liquid to gaseous state under specific temperature conditions, which is of great significance in chemical separation and purification processes.
Third, its melting point is low, roughly around -87 ° C. This characteristic allows 1% 2C3-divinylbenzene to maintain a liquid state at room temperature, providing convenience for practical operation and use.
Fourth, in terms of density, it is about 0.918 - 0.925g/cm ³, which is slightly lighter than water. In the process of liquid-liquid mixing or separation, this density difference can be used for the stratification and separation of substances.
Fifth, in terms of solubility, 1% 2C3-divinylbenzene is insoluble in water, but can be miscible with many organic solvents, such as ethanol, ether, acetone, etc. This solubility property is widely used in organic synthesis, coating preparation and other fields, and is often used as a solvent or a raw material to participate in the reaction.
Sixth, at the volatile level, 1% 2C3-divinylbenzene is volatile and can be easily volatilized into the air in an open environment. Due to its irritation, it will affect the environment and human health after evaporation. When using, it is necessary to pay attention to the ventilation of the operating environment.

The chemical properties of 1,3-diene benzene are quite stable. This substance has a conjugated double bond structure, and the conjugated system can cause electron cloud delocalization, reduce molecular energy, and stabilize the structure.
Looking at its chemical behavior, it can resist the action of many common chemical reagents at room temperature and pressure. In case of mild oxidants, such as dilute potassium permanganate solution, it is difficult to oxidize without special conditions. In general acid-base environment, it can also maintain its own structure intact, and it is not easy to hydrolyze or neutralize acid-base reactions.
Investigate its reactivity. Although it contains double bonds, the conjugation effect changes the density distribution of the double bond electron cloud, and the electrophilic addition reactivity is slightly lower than that of isolated double bonds. In order for an addition reaction to occur, relatively severe reaction conditions are often required, such as the presence of specific catalysts, higher temperatures or pressures, etc.
In addition, 1,3-diene benzene molecules can interact with each other by van der Waals forces, and its physical state and stability are also affected by this. In the solid state, the molecules are arranged in an orderly manner and have a certain lattice energy, resulting in relatively stable melting points and boiling points, and are not easy to volatilize or decompose.
In summary, 1,3-diene benzene is chemically stable due to its conjugate structure. It can maintain its own structure in common chemical environments. The reactivity is subject to the conjugation effect, and specific conditions are required to initiate chemical reactions.

1% 2C3-divinylbenzene can be prepared by various methods. It can be obtained through chemical synthesis.
First, vinyl benzene is used as a base, and the vinyl groups are interacted and polymerized under specific reaction conditions to obtain 1% 2C3-divinylbenzene. Among them, a suitable catalyst needs to be selected to make the reaction proceed towards the formation of the target product. The catalyst can promote the reaction rate, but its type and dosage are all related to the purity and yield of the product. If a specific metal salt catalyst is selected, the reaction between vinylbenzene can occur in an orderly manner at a specific temperature and pressure, resulting in the formation of 1% 2C3-divinylbenzene.
Second, or from other vinyl-containing compounds, converted through a series of chemical reactions. First, these compounds are pretreated to expose or activate their activity check points, and then they interact to gradually build the molecular structure of 1% 2C3-divinylbenzene. In this process, it is extremely important to control the reaction environment, such as the pH of the reaction system, the type of solvent, etc., which will affect the process of the reaction and the quality of the product.
Third, there are also methods of chemical modification and transformation of natural products as starting materials. Natural products may contain available structural units, which can be transformed into 1% 2C3-divinylbenzene through ingenious chemical means. Although this approach is innovative to a certain extent, it often faces difficulties such as difficulty in obtaining raw materials and cumbersome reaction steps. Researchers need to carefully design reaction routes for the purpose of efficient preparation.
All these preparation methods have advantages and disadvantages. Researchers need to weigh and choose according to actual needs, availability of raw materials, cost considerations and many other factors in order to achieve the best preparation effect.

1% 2C3-divinylbenzene is commonly used in chemical industry. During storage and transportation, many matters need to be paid attention to.
It is flammable. When storing, it must be kept away from fire and heat sources, and placed in a well-ventilated place. The temperature of the warehouse should be controlled to prevent its volatilization from intensifying due to excessive temperature and increasing the risk of fire. And it should be stored separately from oxidants, acids, and alkalis. It must not be mixed. The cover is easy to react with various chemicals and cause danger.
When transporting, the transportation vehicle should be equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. Summer transportation should be selected in the morning and evening to avoid high temperature, in case the temperature rises, the material evaporates and increases the danger. During transportation, make sure that the container does not leak, collapse, fall or damage. Before and after loading and unloading, the transportation tools should be thoroughly cleaned and washed, and it is strictly forbidden to mix with organic matter, flammable substances and other impurities.
Furthermore, 1% 2C3-divinylbenzene also has certain hazards to the human body. Contact can cause skin and eye irritation, and inhalation of its vapor can cause respiratory tract irritation. Therefore, storage and transportation personnel need to be professionally trained. When operating, they should wear protective clothing, protective gloves and goggles, etc., and take protective measures. If a leak occurs accidentally, quickly evacuate the personnel from the leaked contaminated area to the safe area and isolate them, strictly restricting access. Emergency responders need to wear protective gear to avoid contacting leaks with combustible substances (such as wood, paper, oil, etc.). Small leaks can be absorbed by inert materials such as sand and vermiculite. Large leaks need to be contained by building embankments or digging holes, covered with foam to reduce vapor disasters, and then transferred to a tanker or special collector with an explosion-proof pump for recycling or transportation to a waste treatment site for disposal.
