What are the physical properties of (chloromethyl) ethyl-benzene?
(Chloromethyl) ethylbenzene is also an organic compound. Its physical properties are quite important, let me come one by one.
Looking at its shape, under normal conditions, (chloromethyl) ethylbenzene is a colorless to light yellow liquid, with a clear texture, like a clear spring, without special turbidity or impurities.
Smell its smell and exude an aromatic smell. This aroma is not rich and pungent, but has a mild aroma unique to benzene series. However, its potential irritation cannot be ignored. If it is smelled for too long, it may cause olfactory discomfort.
When it comes to boiling point, it is about a certain temperature range. This temperature is the key node for its transformation from liquid to gaseous state. Specifically, its boiling point is affected by factors such as intermolecular forces, and is around a certain exact value. This value is of great significance for chemical operations such as distillation and separation.
Its melting point is also one of the important physical properties. Under specific low temperature environments, (chloromethyl) ethylbenzene will solidify from liquid to solid. The determination of this melting point is indispensable for material identification and storage conditions setting.
As for density, it is slightly heavier than water. When (chloromethyl) ethylbenzene is mixed with water, it can be clearly seen that it sinks in the bottom of the water, such as pearl sedimentation. This characteristic can be used in the process of liquid-liquid separation.
In terms of solubility, (chloromethyl) ethylbenzene is insoluble in water, just like the incompatibility of oil and water. However, in many organic solvents, such as ethanol and ether, it has good solubility, just like fish get water. This property makes it a commonly used solvent or reaction medium in organic synthesis and related chemical reactions.
In summary, the physical properties of (chloromethyl) ethylbenzene play a key role in many fields such as chemical industry and scientific research, laying the foundation for people to recognize and utilize this compound.
What are the chemical properties of (chloromethyl) ethyl-benzene
(Chloromethyl) ethyl-benzene is also an organic compound. It is active in nature and has the properties of halogenated hydrocarbons and aromatic hydrocarbons.
Looking at the properties of halogenated hydrocarbons, chlorine atoms in chloromethyl chloride are active. It can meet nucleophilic reagents, such as sodium alcohol, according to the method of nucleophilic substitution, it forms a genus of ethers. If it is sodium cyanide, the cyanide substitutes chlorine to obtain the derivative of nitriles, which can be hydrolyzed into carboxylic acids. In case of water and alkali co-heating, chlorine is replaced by hydroxyl groups, and it has the quality of alcohols. In the alkali solution of alcohol, it can eliminate hydrogen chloride and form the structure of alkenes.
On the properties of aromatic hydrocarbons In the reaction of electrophilic substitution, benzene is easier to encounter with halogenating agents, nitrating agents, sulfonating agents, etc. In halogenation, chlorine or bromine is catalyzed by iron or its halides into the ortho and para-position of the benzene ring. During nitration, concentrated nitric acid and concentrated sulfuric acid are co-nitrating agents, resulting in the production of nitro ortho and para-position. During sulfonation, fuming sulfuric acid or concentrated sulfuric acid is used as an agent, and the sulfonic acid group is also ortho and para-position.
And the alkyl group of (chloromethyl) ethyl-benzene has α-hydrogen, which can be taken by chlorine or bromine to form α-halides under light or high temperature. Due to its diverse chemical properties, it is an essential material for the production of complex organic molecules in the field of organic synthesis.
What are the synthesis methods of (chloromethyl) ethyl-benzene?
The method of preparing (chloromethyl) ethyl-benzene has various paths. First, ethyl-benzene can interact with chloromethylation reagents. Among them, the commonly used chloromethylation reagents are trimethylene and hydrogen chloride. The mechanism of the reaction is that trimethylene is first depolymerized into formaldehyde under the catalysis of hydrogen chloride, and then formaldehyde and hydrogen chloride generate chloromethanol, and then undergoes an electrophilic substitution reaction with ethyl-benzene to obtain (chloromethyl) ethyl-benzene.
Furthermore, benzyl alcohol derivatives can also be used as starting materials. First, ethyl-benzene is acylated by Friedel-Crafts to introduce an acyl group to generate a corresponding ketone, and then the ketone is reduced to an alcohol, and then the alcohol hydroxyl is chlorinated. For the method of chlorination, reagents such as dichlorosulfoxide and phosphorus trichloride can be selected. Taking dichlorosulfoxide as an example, it reacts with alcohol under mild conditions and few side reactions, which can efficiently convert the alcohol into chlorine, thereby obtaining (chloromethyl) ethyl-benzene.
There is also a method of reacting with benzene derivatives by halogenated alkanes. If there is a suitable halogenated ethylbenzene, a chloromethyl group can be introduced under appropriate catalyst and reaction conditions. For example, with the help of some metal catalysts, the coupling reaction of halogenated ethylbenzene with chloromethylation reagents can achieve the purpose of preparation. In this process, the temperature of the reaction, the amount of catalyst, the ratio of reactants and other factors need to be carefully adjusted to improve the yield and purity of the product. All methods have their own advantages and disadvantages, and they need to be selected according to the actual situation.
What should be paid attention to when storing and transporting (chloromethyl) ethyl-benzene?
For (chloromethyl) ethylbenzene, it is very important to pay attention to various matters during storage and transportation.
This substance has a certain chemical activity, and the first thing to store is to choose a cool and well-ventilated place. Avoid direct sunlight, if exposed to strong light, or cause it to undergo chemical reactions, and even endanger safety. And the temperature also needs to be properly controlled. Overheating or overcooling may affect its stability.
Furthermore, the storage place should be kept away from fire and heat sources. Because of its flammability, it is easy to cause combustion and even explosion in case of open flames and hot topics. Therefore, fireworks are strictly prohibited around, and fire protection facilities should be complete and easy to use.
In terms of packaging, it must be tightly sealed to prevent it from coming into contact with air, moisture, etc. Due to its chemical properties, it interacts with certain components or moisture in the air, or causes deterioration, and may also escape harmful gases, endangering the environment and personal safety.
When transporting, caution must also be taken. The carrier should be clean and dry, and no other chemicals should remain to prevent mutual reaction. The transportation process should be smooth, avoid bumps and vibrations, and avoid leakage caused by package damage. And the transporter should be familiar with the characteristics of this substance and emergency treatment methods. In case of emergencies, they can respond quickly and correctly.
Escort personnel should not be slack, and they must pay close attention to the status of the substances in transit to ensure their safe delivery to the destination. This is all necessary for the storage and transportation of (chloromethyl) ethylbenzene.
