The synthesis method of 5-bromo-2 - (diethylaminoformyl) -1,3-diethylbenzene is related to the field of organic synthesis. To obtain this compound, various routes can be followed.

First, it can be started by the corresponding halobenzene derivative. First, take a halobenzene containing a suitable substituent, so that the diethylaminoformylation reagent can act under suitable reaction conditions. This reaction requires careful selection of solvents, such as dichloromethane, N, N-dimethylformamide, etc., and the reaction temperature and time need to be adjusted depending on the characteristics of the reagents used. Generally speaking, under mild heating conditions, the introduction of diethylaminoformyl groups may be achieved when stirring for a few times. Then, the ethylation operation is carried out for other positions on the benzene ring. Ethyl halide can be selected, such as bromoethane, which can be replaced by ethyl under the catalysis of alkali. The alkali can be selected from potassium carbonate, sodium hydroxide, etc., and the reaction environment should be an aprotic solvent.

Second, benzene derivatives can also be used as raw materials to construct the skeleton of diethylbenzene first. Diethylbenzene derivatives can be formed by the alkylation reaction of Fu-g, using benzene and halogenated ethane in a Lewis acid catalyst, such as aluminum trichloride. Then, the specific position on the benzene ring can be brominated, and liquid bromine can be used to complete the catalysis under an appropriate catalyst, such as iron powder. Finally, the obtained brominated diethylbenzene is reacted with diethylamino formylation reagent to achieve the synthesis of the target compound.

During the synthesis process, close attention should be paid to the precise control of the reaction conditions. Due to slight changes in the reaction conditions, the yield and purity of the product may vary. And after each step of the reaction, separation and purification operations should be carried out to ensure the smooth progress of subsequent reactions. In this way, the reaction with careful design and operation in multiple steps may successfully synthesize 5-bromo-2 - (diethylaminoyl) -1,3-diethylbenzene.

What are the physical properties of 5-bromo-2- (difluoromethoxy) -1,3-difluorobenzene

5-Bromo-2 - (diethylaminoformyl) -1,3-diethylbenzene, is a kind of organic compound. Its physical properties have several characteristics.

Looking at its physical state, under normal temperature and pressure, it often takes the form of a liquid. This is due to the specific situation of intermolecular forces, which makes it maintain a liquid state under these conditions. Its color is mostly colorless to light yellow transparent liquid, which is as clear as water, but has a slight yellowish rhyme, like the scene of morning light sprinkling clear liquid.

As for the smell, it has a special aromatic smell, similar to the smell of some aromatic hydrocarbons, but mixed with a unique rhyme, unusual aromas can be compared, and there seems to be a hidden fragrance hidden in it.

When it comes to solubility, this substance has good solubility in organic solvents, such as ethanol, ether, chloroform, etc. This is because the molecular structure and organic solvent molecules are similar and compatible, and they can be harmonious with each other. However, in water, its solubility is very small. Due to the large difference between molecular polarity and water molecular polarity, the two are difficult to fuse, just like the state of oil and water. < Br >
Then again, density is heavier than water. If it is placed in a container with water, it can be seen that it slowly sinks to the bottom of the water, like a stable stone, not floating in water.

Boiling point, due to the complex molecular structure and strong intermolecular forces, the boiling point is quite high. It needs to reach a certain temperature to change from liquid to gaseous state, break free from intermolecular bondage, and rise in the air.

Melting point also has a specific value. When the temperature drops below the melting point, the substance solidifies from liquid to solid, and the form changes. For example, water freezes into ice and becomes solid.

The physical properties of this 5-bromo-2 - (diethylaminoformyl) -1,3-diethylbenzene are determined by its molecular structure, and the structure and properties are closely related and complement each other, laying the foundation for its application in various fields.

What are the chemical properties of 5-bromo-2- (difluoromethoxy) -1,3-difluorobenzene

5-Hydroxy-2- (diethylaminoethyl) -1,3-diethylbenzene, the chemical properties of this substance are as follows:

It is basic, because the molecule contains diethylamino, and the nitrogen atom has lone pair electrons. It can bind protons and form salts in acidic environments. If it reacts with hydrochloric acid, it generates corresponding ammonium salts to improve its water solubility.

5-Hydroxy-2- (diethylaminoethyl) -1,3-diethylbenzene contains hydroxyl groups and can exhibit typical properties of alcohols. Esterification reactions can occur, and esters are formed with carboxylic acids under catalyst and heating conditions. For example, react with acetic acid to form acetates. In case of strong oxidizing agent, the hydroxyl group may be oxidized, depending on the conditions, or form an aldehyde group or a carboxyl group.

The benzene ring in the molecule imparts its aromaticity and can undergo a characteristic reaction of the benzene ring. Such as halogenation reaction, under the action of catalyst, reacts with halogen, and halogen atoms replace hydrogen atoms on the benzene ring. Take bromination reaction as an example. Under the catalysis of iron bromide, bromine atoms can replace hydrogen atoms at specific positions on the benzene ring. Nitration reaction can also occur. It reacts with mixed acids of concentrated nitric acid and concentrated sulfuric acid, and the benzene ring introduces nitro groups.

In addition, its hydrocarbon group part can undergo some reactions. For example, the side chain of diethylbenzene can undergo oxidation reaction under specific conditions. If the carbon atoms connected to the benzene ring on The carbon-nitrogen bond of the diethylaminoethyl moiety can be broken under some conditions, and reactions such as substitution or elimination can occur, but such reactions usually require specific reagents and conditions to achieve.

What is the price range of 5-bromo-2- (difluoromethoxy) -1,3-difluorobenzene in the market?

5-Hydroxy- 2 - (diethylaminoformyl) - 1,3-diethylbenzene, this substance is in the market, its price is variable, mostly due to quality, supply and demand, season and production and sales conditions vary.

In today's market, if it is of ordinary quality and the batch is still small, the price per catty may be around a hundred; if the quantity is quite large, or the price is slightly reduced due to bargaining, it is unknown to drop to eighty. If its quality is high, and it is in line with all kinds of strict regulations, the price will soar, and the price per catty can reach more than one hundred and fifty, or even nearly two hundred.

However, the market situation changes, like an illusion. If there is a lot of production and supply, but the demand has not increased, the price will fall; if there is a shortage of supply and supply, and there are many people who want it, the price will rise. And the difference in prices in various places cannot be ignored. In prosperous places, commercial taxes and rents are high, and their prices are more expensive in remote places. It is easy to change over time. The abundance of raw materials and the new reasons for craftsmanship are all related to the price.

If you want to know the exact price, you need to consult the merchants in person, compare their similarities and differences, and observe their advantages and disadvantages before you can buy it at a suitable price. The market is impermanent, and the price is not fixed. This is the general principle of business.
