2-% -1-oxo-3-methylbenzene, that is, methylphenol. This substance is a chemical compound with polymorphism.
It is solid under normal conditions, melts at 30 ° C, and boils at 191 ° C. Because the molecule contains a phenolic group, it has certain properties. It is slightly soluble in water, and is easily soluble in ethanol, ethyl ether, etc. Its properties allow water molecules to form a phenolic group. However, due to the hydrophobicity of the phenolic group, its water solubility is limited.
Methylphenol has a special taste, slightly characteristic of phenolic, and this taste can be used for identification. Its phase density is 1.0273, which is slightly heavier than water. In terms of performance, low-quality compounds have low performance, and their speed is slow under normal conditions.
Under the action of light and space, they are easily oxidized, resulting in deep color, initial color, long-term light color or even darker color. In addition, due to the existence of phenol groups, the density of benzene clouds increases, making it easier to generate benzene substitution reactions, such as substitution, nitrification, etc.

Knowing its properties is a prerequisite for rational use.

The 2-%-1-oxo-3-methylnaphthalene is a compound that has chemical properties. Its chemical properties are special, and it is like a chemical reaction due to its chemical properties.
In terms of its chemical properties, first of all, it can be the typical reaction of its aromatic properties. The presence of aromatic properties makes it possible to replace the chemical reaction, such as nitrification, sulfonation, and so on. With nitrification and anti-chemical, in the appropriate case, the nitro group can replace the chemical atom on the aromatic. This is because of the high density of the aromatic daughter cloud, which is easy to attract. The mixed acid of nitric acid and sulfuric acid is mixed, and the nitro-n-ion (NO 2O) is used to attack the aromatic.
Furthermore, the methyl group also has anti-reactive activity. Under the shadow of aromatic acid, the activity of α-atoms on the methyl group is improved. In the presence of catalysis or light, free radicals can be generated to replace anti-reactive groups. For example, when the element is irradiated with light, the element radical can grab α-on the methyl group to form a methyl naphthalene derivative.
In addition, when this compound is oxidized, aromatic or reactive can be oxidized. If the oxidizing element is suitable, such as high acid, etc., under specific conditions, the methyl group can be oxidized to a carboxyl group to obtain a phase of naphthalenecarboxylic acid derivatives.
In addition, due to the presence of atoms such as chlorine and oxygen in the molecule, chlorine atoms can be formed, which may have implications for their physical rationality and the activity and stability of some chemical reactions. The existence of oxygen atoms may make the chemical properties of the molecule different, which may affect its solubility and equivalence in different solubilities.
Therefore, the chemical properties of 2-1-oxygen-3-methylnaphthalene are enriched, the anti-properties of its aromatics, and the interaction of atoms in the molecule. Together, the surface of it in the chemical reaction is determined, and the synthesis and other domains provide many possibilities.

To prepare 2-bromo-1-pentene-3-methylbenzene, you can do it as follows.
Take 1-pentene-3-methylbenzene first, which is the starting material of the reaction. Place it in a suitable reaction vessel and add an appropriate amount of brominating reagent. The commonly used brominating reagent can be liquid bromine, accompanied by a suitable catalyst, such as iron powder or iron tribromide.
During the reaction, pay attention to the conditions of the reaction. The temperature should be controlled within a certain range, usually low temperature helps to control the selectivity of the reaction, which can make the reaction give priority to the formation of the target product. In general, the temperature can be maintained between 0 ° C and room temperature.
During the reaction, liquid bromine under the action of a catalyst produces positive bromide ions. In 1-pentene-3-methylbenzene, the carbon-carbon double bond is rich in electrons, which is nucleophilic, and is easy to undergo electrophilic addition reaction with positive bromide ions. Due to the specific position of the double bond, the positive bromide ion attacks the carbon atom at one end of the double bond to form a carbon positive ion intermediate. This intermediate can exist stably due to the conjugation effect of benzene ring and the electron effect of methyl. Subsequently, the negative bromide ion in the system attacks the carbon positive ion, thereby generating 2-bromo-1-pentene-3-methylbenzene. After the
reaction, the product is mixed in the reaction system and needs to be separated and purified. The organic phase can be extracted by organic solvent first, and the organic phase can be separated from the aqueous phase. After that, the product is further purified by distillation, column chromatography and other methods to obtain high-purity 2-bromo-1-pentene-3-methylbenzene. In this way, the purpose of preparing 2-bromo-1-pentene-3-methylbenzene can be achieved.

Preparation of 2-bromo-1-pentene-3-based methyl ether requires attention to many matters.
The first thing to choose is the raw material. 2-bromo-1-pentene-3-ol and methylation reagents must be of good quality and purity, impurities will seriously interfere with the reaction process and product purity. For example, if 2-bromo-1-pentene-3-ol contains other alcohol impurities, a variety of by-products may be formed during methylation.
The reaction conditions are extremely critical. Temperature control needs to be precise, the temperature is too low, the reaction rate is slow, and it takes a long time; if the temperature is too high, it is easy to cause side reactions, such as the addition of olefin double bonds. Take the common Williamson synthesis method as an example, usually in a suitable organic solvent, the reaction is catalyzed by alkali. At this time, the amount and strength of alkali should be appropriate. If the amount of alkali is insufficient, it is difficult to convert alcohol into sodium alcohol, and the reaction is difficult to advance. If the amount of alkali is too much or too alkaline, it may lead to side reactions such as the elimination of halogenated hydrocarbons.
The choice of reaction solvent should not be underestimated. Solvents that have good solubility to raw materials and products and do not participate in the reaction should be selected. For example, polar aprotic solvents such as DMF and THF can not only If the wrong solvent is selected, there may be a situation where the raw materials are not well dispersed and the reaction is difficult to occur fully.
Post-processing can not be ignored. After the reaction, the product needs to be separated and purified by suitable methods. Common methods include extraction, distillation, column chromatography, etc. During extraction, the right extractant should be selected to ensure that the product is effectively transferred to the organic phase; during distillation, the temperature and pressure should be controlled to achieve separation according to the difference in the boiling point of the product and impurities; column chromatography should select the right adsorbent and eluent to achieve efficient separation of the product and impurities.
The entire preparation process, from raw materials, reaction conditions to post-processing, every detail is related to the quality and yield of the product, which needs to be carefully operated and strictly controlled.
