The physical properties of (2-chloroethyl) benzene, also known as phenethyl chloride, are as follows:
It is a colorless to light yellow liquid at room temperature and pressure, and it has a certain fluidity. Smell it, it has a special aromatic smell, but this smell may be irritating.
In terms of its density, it is heavier than water. If mixed with water, it will sink underwater. Its boiling point is about 197-200 ° C. At this temperature, the liquid (2-chloroethyl) benzene will be converted into a gaseous state. The melting point is about -43 ° C. When the temperature drops below this point, it will solidify from liquid to solid.
(2-chloroethyl) benzene is insoluble in water, because of its molecular structure, it is difficult to form an effective interaction with water molecules. However, it is soluble in many organic solvents, such as ethanol, ether, acetone, etc. In these organic solvents, it can be well dispersed and dissolved. This property makes it have specific applications in organic synthesis and other fields.
In addition, its refractive index is also an important physical property, about 1.532 - 1.537. This value reflects the degree of refraction of light when passing through the substance, which is of great significance for identifying and studying the behavior of the substance in optics.

(2-Chloroethyl) benzene | phenethyl Chloride
(2-Chloroethyl) benzene, also known as phenethyl chloride, has the following chemical properties:
In this compound, the chlorine atom is attached to the ethyl terminal of the phenethyl group. Due to the strong electronegativity of the chlorine atom, the molecule has a certain polarity. From the perspective of nucleophilic substitution reaction, since the chlorine atom can be used as a leaving group, the compound can undergo nucleophilic substitution reaction. In case of nucleophilic reagents, such as sodium alcohol, amines, etc., the chlorine atom will be replaced by the nucleophilic reagent to form a new compound. For example, in reaction with sodium ethanol, the chlorine atom is replaced by an ethoxy group to form phenethyl ether.
In terms of elimination reaction, when (2-chloroethyl) benzene is in an alkaline environment and the conditions are suitable, the elimination reaction will occur. The chlorine atom in the molecule and the hydrogen atom on the adjacent carbon atom remove hydrogen chloride under the action of the base, form a carbon-carbon double bond, and form styrene compounds.
It can also participate in free radical reactions. In the presence of light or initiators, chlorine atoms are easily detached from the molecule to form chlorine radicals, which in turn triggers a series of free radical chain reactions, such as addition reactions with other free radicals to generate complex organic compounds.
In addition, due to the presence of benzene rings, the compound has some properties of aromatic hydrocarbons. Benzene ring can undergo electrophilic substitution reaction, but due to the influence of side chain, the reactivity and selectivity will be different from benzene. For example, under appropriate conditions, halogenation, nitrification, sulfonation and other electrophilic substitution reactions can occur, and corresponding substituents can be introduced into the benzene ring.

What are the synthesis methods of (2-chloroethyl) benzene | phenethyl Chloride
(2-Chloroethyl) benzene, also known as phenethyl chloride, has many synthesis methods, which are described in detail today.
First, styrene is used as the raw material. The addition of styrene to hydrogen chloride requires the reaction to be carried out at a suitable temperature and in the presence of a catalyst. Usually high-activity catalysts, such as certain metal halides, can promote the smooth occurrence of the reaction. The carbon-carbon double bond of styrene is nucleophilic to hydrogen chloride. The hydrogen atom of hydrogen chloride binds to the carbon atom at one end of the double bond, and the chlorine atom is connected to the carbon atom at the other end to form (2-chloroethyl) benzene. The advantage of this method is that the raw material styrene is easy to obtain, the reaction conditions are relatively mild, and the yield is quite high.
Second, phenethane is used as the starting material. First, phenethane is chlorinated under the action of light or initiator. Because the α-hydrogen atom of phenethane is affected by the benzene ring, it has a certain activity. Under the action of light or initiator, chlorine radicals can capture α-hydrogen atoms, and then generate (2-chloroethyl) benzene. However, this reaction has poor selectivity. In addition to generating the target product, it may also produce by-products such as polychlorinated substitutes, and subsequent separation and purification are more complicated.
Third, benzyl chloride and formaldehyde are used as raw materials to react under alkaline conditions. The chlorine atom of benzyl chloride has strong activity. In alkaline environment, the carbonyl group of formaldehyde can undergo nucleophilic substitution reaction with benzyl chloride, and through a series of intermediate steps, (2-chloroethyl) benzene is finally generated. This method requires precise control of the reaction conditions. Factors such as alkalinity, reaction temperature and time have a great influence on the reaction process and product purity.
Each method for synthesizing (2-chloroethyl) benzene has its own advantages and disadvantages. In practical application, it is necessary to comprehensively consider many factors such as raw material availability, cost, and product purity requirements, and choose carefully.
