What are the physical properties of 2-Chloroethyl-Benzene?

2-Chloroethyl-benzene is one of the organic compounds. Its physical properties are worth a detailed investigation.
Looking at its physical state, under room temperature and pressure, 2-chloroethyl-benzene is often colorless to light yellow liquid, with a clear texture and no cloudy appearance.
As for its smell, it has a fragrant smell, but this fragrance is not purely pleasant, slightly irritating, and its special smell can be sensed by the smell, which is easy to be felt in the air.
When it comes to the melting point, the melting point is low, about -70 ° C, which makes it a liquid at room temperature; while the boiling point is relatively high, about 197-198 ° C. The reason why the boiling point is high is due to the characteristics of its intermolecular forces, which also make it difficult to rapidly vaporize and dissipate when heated.
2-chloroethyl-benzene has a density slightly higher than that of water, about 1.067g/cm ³, so if it is mixed with water, it must sink in water, and the two are insoluble, and the stratification is clear.
In terms of solubility, its solubility in water is very small, because it is an organic compound, and its polarity is quite different from that of water, following the principle of "similar miscibility". However, in organic solvents, such as ethanol, ether, acetone, etc., it has good solubility and can be miscible with various organic solvents as a uniform phase.
In addition, 2-chloroethyl-benzene is moderately volatile. Although it is not as volatile as low-boiling substances, it will also evaporate in an open environment over a long time. And its vapor is heavier than air and can spread to a considerable distance at a lower place. In case of open flame and high heat, it can cause combustion and explosion. When using and storing, care should be taken to prevent the risk of accidents.

Is 2-Chloroethyl-Benzene chemically stable?

The stability of the chemical properties of 2-chloroethyl-benzene depends on many factors, and it is difficult to generalize.
When it comes to stability, its molecular structure needs to be observed. In this compound, the benzene ring has a conjugated system, which is quite stable. However, the chloroethyl group is connected to the benzene ring, which causes its chemical properties to be variable. The chlorine atom has electron-absorbing properties, which can affect the electron cloud density distribution of the benzene ring and slightly change the activity of the benzene ring.
Under normal conditions, 2-chloroethyl-benzene may maintain a certain stability. However, in special circumstances, such as high temperature, strong acid, strong base, or in the case of specific catalysts, its stability may be challenged.
When the temperature is high, the intramolecular energy increases, the chemical bond activity increases, or the chlorine atom is dissociated, causing the reaction to occur. Strong acids and bases can also change the electron cloud distribution of the compound, or cause the chlorine atom to leave, leading to nucleophilic substitution and other reactions.
If there is a specific catalyst, the activation energy of the reaction can be reduced, which makes the originally difficult reaction possible and damages its stability.
And its stability is also related to the environment, in the air, or gradually changes due to the action of oxygen, water vapor, etc. In summary, the stability of 2-chloroethyl-benzene is not absolute and varies according to external conditions and reaction environments.

What is 2-Chloroethyl-Benzene production method?

For 2-chloroethyl-benzene, the ancient people also studied the method of preparation. In the past, this compound was prepared by following a specific path.
One method is to use benzene and chloroethanol as raw materials. Put benzene in an appropriate reaction vessel, such as a retort, and add an appropriate amount of chloroethanol. Then, add some kind of catalyst, such as sulfuric acid, to promote its reaction. Heat this mixture and maintain a certain temperature, just like the ancient people's alchemy and keep the heat, so that the two can chemically react. During the reaction, part of the structure of chloroethanol is combined with benzene to produce 2-chloroethyl-benzene.
Another method is to use vinylbenzene as the starting material. First, vinylbenzene is introduced into another special vessel, and a specific reagent is added, or a chlorine-containing agent is introduced. Under suitable conditions, vinylbenzene is interacted with chlorine-containing reagents. During this process, the double bond of vinylbenzene changes, and chlorine atoms are introduced into it, eventually forming 2-chloroethyl-benzene.
When preparing, many details need to be paid attention to. For example, the proportion of raw materials must be accurately measured, just like the ancients dispensing medicines, and it is exactly the same. The temperature and time of the reaction must also be properly controlled. If the temperature is too high, the reaction will be too fast, and the product may be impure; if the temperature is too low, the reaction will be slow and take a long time. The reaction environment must be clean, stable, and free from foreign interference, so that pure 2-chloroethyl-benzene can be prepared.

2-Chloroethyl-Benzene What are the precautions during storage and transportation?

2-Chloroethyl-benzene, during storage and transportation, be sure to pay attention to many matters.
The first word is storage. Its nature is a chemical substance, and it should be stored in a cool, dry and well-ventilated place. Do not place it in a high temperature or humid place. High temperature can cause it to evaporate and accelerate, or cause chemical reactions, and moisture can easily rust and damage the packaging, endangering the safety of the substance. In the warehouse, it should also avoid open fires and hot topics, because it is flammable. In case of open flames or hot topics, there is a risk of fire or even explosion. Furthermore, it must be placed separately from oxidizing agents, acids, alkalis and other substances, because 2-chloroethyl-benzene is prone to chemical reactions with such substances, causing danger. Regularly inspect the warehouse to check whether the packaging is damaged or leaking. If there is such a situation, dispose of it immediately to prevent material leakage.
Times and transportation. Transportation equipment must be tight and firm to prevent package damage due to bumps and collisions on the way. The selected transportation vehicles should be equipped with corresponding fire fighting equipment and leakage emergency treatment equipment. During transportation, the driving route should be avoided from densely populated areas and important transportation hubs to prevent accidental leakage from causing significant impact on many people and traffic. Transport personnel must also be professionally trained to be familiar with the properties, hazards and emergency treatment methods of 2-chloroethyl-benzene. During loading and unloading, the operation must be cautious, light handling and light handling, and no brutal operation, so as not to damage the packaging and cause leakage.
In general, during the storage and transportation of 2-chloroethyl-benzene, strict safety regulations and careful operation should be strictly observed to effectively prevent accidents and ensure that personnel safety and the environment are not endangered.
