What are the physical properties of 1-chloro-4-ethenyl-Benzene?
1 - chloro - 4 - ethenyl - Benzene, that is, p-chlorobenzene, is an organic compound and is widely used in the chemical industry. Its physical properties are as follows:
- ** Properties **: Under normal conditions, p-chlorobenzene is a colorless to light yellow liquid with a pure and translucent appearance and no obvious impurities. This property makes it convenient to apply in many industrial production and experimental scenarios with strict requirements on appearance.
- ** Odor **: It has a unique aromatic smell. Although the smell is not extremely strong and pungent, its uniqueness can be used as one of the basis for identifying the substance. During production, storage and use, operators can use this smell to initially detect whether there are abnormal conditions such as leakage.
- ** Boiling Point **: The boiling point is about 197 - 200 ° C. A higher boiling point means that a higher temperature is required to transform it from liquid to gaseous state. This characteristic plays a key role in setting process conditions in chemical operations such as distillation and separation involving the gasification and condensation of substances. For example, when separating p-chlorostyrene and other mixtures with large boiling points, the boiling point characteristics can be used to precisely control the temperature and achieve efficient separation.
- ** Melting Point **: The melting point is about -22 ° C. A lower melting point indicates that the substance can be converted from solid to liquid at relatively low temperatures. When storing and transporting in a low temperature environment, this characteristic needs to be considered to prevent the change of the material state from affecting its quality or packaging.
- ** Density **: The density is about 1.06 g/cm ³, which is slightly higher than the density of water. This property is significant in systems involving liquid-liquid separation or coexistence with water. For example, in some reaction systems, if p-chlorostyrene is generated to be immiscible with water, it will appear stratification due to the density difference, so that preliminary separation can be achieved by operations such as liquid separation.
- ** Solubility **: It is difficult to dissolve in water, but it is soluble in most organic solvents, such as ethanol, ether, acetone, etc. This solubility characteristic determines its application in organic synthesis. In organic reactions, its solubility in organic solvents is often used to select a suitable solvent to build a reaction environment and promote the reaction. At the same time, when treating wastewater containing p-chlorostyrene, due to its insoluble nature in water, special treatment processes such as extraction are required to separate it from the water.

What are the chemical properties of 1-chloro-4-ethenyl-Benzene?
1 - chloro - 4 - ethenyl - benzene is p-chlorostyrene, which is one of the organic compounds. Its chemical properties are unique and worth exploring.
p-chlorostyrene has the dual characteristics of olefins and halogenated aromatics. In terms of olefin properties, carbon-containing double bonds are the check point for its active reaction. Addition reactions can occur. In case of bromine water, the double bonds are opened, and the bromine atoms are added to the two carbon atoms to form dibromide, which is like "double dragons play beads, beads fall double forks". Under suitable catalysts and temperatures, it can be added with hydrogen to turn double bonds into single bonds, resulting in saturated halogenated aromatics, similar to "double bond unloading, stable transformation".
And because it contains halogen atoms, it has the properties of halogenated aromatics. In strong alkali alcohol solutions, chlorine atoms can be replaced by hydroxyl groups, and after elimination reactions, p-vinylphenol is formed, which can be described as "chlorine separates from hydroxyl groups and rearranges the structure". In the nucleophilic substitution reaction, chlorine atoms are also easily replaced by nucleophilic reagents, such as cyano, amino groups, etc., to construct new compounds, just like "the abdication of the old master and the enthronement of the new master".
In addition, p-chlorostyrene is relatively stable due to its conjugated system and can participate in the polymerization reaction. Under the action of the initiator, the carbon-carbon double bonds are connected one by one to polymerize into high molecular polymers, which are widely used and have many achievements in the field of materials, like "monomers holding hands and converging into forests". Its chemical properties are diverse, providing many possibilities for organic synthesis and material preparation, and are of great significance in chemical research and industrial production.

What is 1-chloro-4-ethenyl-Benzene production method?
1-Chloro-4-ethenyl-Benzene is p-chlorobenzene, and its preparation method is as follows:
Ancient preparation method, or there are various paths. First, p-chlorotoluene can be used as the starting material. First, p-chlorotoluene and N-bromosuccinimide (NBS) are used in the presence of an initiator such as benzoyl peroxide to carry out a free radical substitution reaction. This reaction is the introduction of bromine atoms at the benzyl position of toluene to generate p-chlorobenzyl bromide. P-chlorobenzyl bromide is then co-heated with a strong base such as sodium hydroxide alcohol solution. After the elimination reaction, hydrogen bromide is removed to obtain p-chlorobenzene. The chemical reaction formula is as follows:
p-chlorotoluene + NBS (initiator) → p-chlorobenzyl bromide
p-chlorobenzyl bromide + NaOH (alcohol solution) → p-chlorobenzene + NaBr + H2O O
Second, p-chlorobenzaldehyde can also be prepared from p-chlorobenzaldehyde. First, p-chlorobenzaldehyde is reacted with phosphine Yelide reagent, that is, Wittig reagent. Wittig reagent is prepared by reacting triphenylphosphine with halogenated hydrocarbons and then reacting with strong bases. P-chlorobenzaldehyde reacts with Wittig reagent. Through the Wittig reaction mechanism, the carbon anion of the aldehyde group and the phosphine Yelide reagent undergoes nucleophilic addition, and then triphenylphosphine oxide is eliminated, thereby generating p-chlorophenylvinyl. The reaction conditions are mild and the product selectivity is high. The reaction formula is roughly as follows:
p-chlorobenzaldehyde + Wittig reagent → p-chlorobenzene + triphenylphosphine oxide
or p-chlorobenzene is used as the starting material, which is first reduced to p-chlorobenzene ethanol, and then catalyzed by concentrated sulfuric acid for dehydration. However, this path step is slightly complicated, and when concentrated sulfuric acid is dehydrated, side reactions may occur, so it is not a commonly used method.
The methods for preparing p-chlorostyrene have their own advantages and disadvantages. It is necessary to choose the appropriate method according to the actual conditions, such as the availability of raw materials, the level of cost, and the purity of the product.
