What are the physical properties of 1- (chloromethyl) -2,4-dimethylbenzene?
1 - (methoxy) -2,4 -dimethylbenzene, this substance has the following physical properties:
It is mostly colorless to light yellow liquid at room temperature, with a special aromatic odor. Because the molecule contains benzene ring and methoxy, methyl and other groups, it has certain chemical stability and specific reactivity.
The boiling point is within a certain range, and the specific impurities are slightly different from the measurement conditions, roughly around [X] ° C. The boiling point is determined by the intermolecular force. The benzene ring and substituents affect the intermolecular van der Waals force, so that the boiling point is maintained at this level, which is of great significance for separation, purification and storage. Appropriate separation methods such as distillation can be selected accordingly. The melting point of
is about [X] ° C. At this temperature, the solid state and the liquid state reach equilibrium. If it is lower than the melting point, it is a solid state, and if it is higher, it is a liquid state. The melting point is affected by the molecular structure. The planar structure of the benzene ring and the spatial arrangement of the substituents change the compactness of the molecule, thereby affecting the melting point. The density of

What are the chemical properties of 1- (chloromethyl) -2,4-dimethylbenzene?
1 - (methoxy) -2,4 -dimethylbenzene, this substance has the following chemical properties:
Its benzene ring structure endows it with certain stability. Due to the presence of methoxy and dimethyl groups on the benzene ring, the compound exhibits unique properties in electrophilic substitution reactions. As a power supply group, methoxy groups can increase the electron cloud density of the benzene ring, which makes the benzene ring more prone to electrophilic substitution reactions, and the electron cloud density of the ortho and para-position of the methoxy group increases more significantly, so the electrophilic reagents are more inclined to attack the ortho and para-position of the methoxy group.
Under the influence of dimethyl, on the one hand, its steric resistance will affect the reaction. When the electrophilic reagent is large, it may hinder the reagent from attacking the position near the methyl group on the benzene ring; on the other hand, methyl is also a donator group, which can also increase the electron cloud density of the benzene ring and further promote the occurrence of electrophilic substitution reactions. However, the superposition of the donator effect of the two methyl groups and the donator effect of the methoxy group will make the electron cloud density distribution of the benzene ring more complex, which will have a comprehensive effect on the reactivity and selectivity.
In addition, the compound may also participate in some redox reactions. If a suitable oxidant is encountered, the oxygen atom in the methoxy group may be oxidized to generate the corresponding oxygenated compound; while the methyl group on the benzene ring may also be oxidized under specific conditions, for example, under the action of a strong oxidant, the methyl group can be gradually oxidized to carboxyl groups.
At the same time, due to the existence of various chemical bonds such as carbon-carbon bonds and carbon-hydrogen bonds in the molecule, under the conditions of high temperature, light or the presence of a specific catalyst, these chemical bonds may break and recombine, triggering a series of chemical reactions, exhibiting rich chemical properties.

What are the synthesis methods of 1- (chloromethyl) -2,4-dimethylbenzene?
The synthesis method of 1 - (formyl) -2,4 - dimethylbenzene is as follows:
First, m-xylene is used as the starting material. M-xylene is first acylated with carbon monoxide and hydrogen chloride in the presence of anhydrous aluminum trichloride and other Lewis acid catalysts under suitable reaction temperature and pressure conditions to obtain 1 - (formyl) -2,4 - dimethylbenzene. In this reaction, carbon monoxide provides formyl groups, and anhydrous aluminum trichloride promotes the smooth progress of the reaction. It interacts with hydrogen chloride to form an active intermediate, and then undergoes an electrophilic substitution reaction with m-xylene to introduce formyl groups at specific positions in the benzene ring.
Second, 2,4-dimethylbenzoic acid is used as raw material. 2,4-dimethylbenzoic acid is first reacted with a reducing agent, such as lithium aluminum hydride, in a suitable organic solvent, which can reduce the carboxyl group to a hydroxyl group to produce 2,4-dimethylbenzyl alcohol. Subsequently, 2,4-dimethylbenzyl alcohol can be oxidized to obtain 1- (formyl) -2,4-dimethylbenzene under the action of a specific oxidant, such as manganese dioxide. In the first step of reduction reaction, lithium aluminum hydride provides hydrogen negative ions, and undergoes nucleophilic addition-elimination reaction with carboxyl groups to convert carboxyl groups into hydroxyl groups; in the second step of oxidation reaction, manganese dioxide oxidizes hydroxyl groups into aldehyde groups to achieve the preparation of the target product.
Third, 2,4-dimethylaniline is used as raw material. 2,4-dimethylaniline is first reacted with sodium nitrite in hydrochloric acid solution to form diazonium salts. After that, the diazonium salts react with carbon monoxide and water in the presence of catalysts such as cuprous chloride to convert diazonium groups into formyl groups, thereby preparing 1- (formyl) -2,4-dimethylbenzene. The diazotization reaction is the reaction of nitrite formed by sodium nitrite and hydrochloric acid with amine to form diazonium salt; in the subsequent reaction, cuprous chloride catalyzes the interaction of diazonium salt with carbon monoxide and water to achieve the introduction of formyl groups.
