To prepare 5-hydroxy-2- (ethylamino) -1,3-diphenyl ether, there are various methods.
First, it can be obtained by the reaction of the corresponding halogenated phenyl ether and ethylamine through nucleophilic substitution. First take a suitable halogenated phenyl ether, place it in a reactor, dissolve it with an appropriate organic solvent, such as dichloromethane, N, N-dimethylformamide, etc., add an appropriate amount of ethylamine, and add potassium carbonate, sodium carbonate and other bases to bind the acid to promote the reaction. Stirring at controlled temperature, depending on the activity of halogenated phenyl ether and the amount of ethylamine, the temperature may be between room temperature and 80 ° C, and the product can be purified by column chromatography or recrystallization.
Second, start with phenolic compounds. First, phenol and halogenated ethane are formed into ethers under the action of bases, such as phenol and bromoethane, which are reacted in sodium hydroxide or potassium hydroxide alcohol solution to form ethoxy phenols. Then, amino groups are introduced through nitrification and reduction. Nitrify with mixed acid of nitric acid and sulfuric acid to obtain nitroethoxy phenol, and then add hydrochloric acid to iron powder, zinc powder, etc., or hydrogen is reduced under a catalyst such as palladium carbon to obtain aminoethoxy phenol. Finally, it reacts with another halogenated phenyl ether to form 5-hydroxy-2- (ethylamino) -1,3-diphenyl ether, and subsequent purification operations are required.
Third, the Ullmann reaction variant can be used. Select suitable halogenated aromatics and phenolic derivatives, use copper salts as catalysts, such as cuprous iodide, ligands such as 1,10-phenanthroline, bases such as cesium carbonate, etc., heat reaction in organic solvents to construct diphenyl ether structures, and then modify amino and hydroxyl groups to obtain the target product. The reaction conditions need to be carefully regulated, and the temperature, catalyst and ligand dosage are all related to the reaction efficiency and product purity.
Each of these methods has its own advantages and disadvantages. In practice, it is necessary to weigh the availability of raw materials, costs, and reaction conditions, and choose the right one.

Today, there is 5-hydroxy- 2 - (ethylamino) - 1,3 - dithiane, what is the market? This is the price of chemical materials, and the market is often affected by many factors.
The cost of raw materials is one of the factors. The cost of raw materials required to make this compound is affected by the supply of raw materials, the ease of production, and the cost of raw materials. If the supply of raw materials is low, or the degree of improvement is high, the cost of raw materials will rise, which will lead to the market of 5-hydroxy- 2 - (ethylamino) - 1,3 - dithiane.
The production industry is also heavy. If the production cost is low, high-end and exquisite skills are required, and the cost of production will increase, and the market price will also be higher. And the production cost of efficient production first may reduce the cost and make the price more reasonable.
The supply and demand system of the city is even more low. If the demand for 5-hydroxyl-2- (ethylamino) -1,3-dithiane is strong in the market, and the supply is limited, the price will rise; conversely, if the supply is low and the demand is low, the price will easily decline.
In addition, different companies have poor or poor quality, and those with high quality often have higher prices. And factors such as sales channels and regions also make the market different.
Therefore, in order to know the market value of 5-hydroxy- 2 - (ethylamino) - 1,3 - dithiane concentrate, it is advisable to add information to the chemical raw material trading platform, the phase operator or the producer, in order to obtain the detailed information.

5 + -Hg-2- (hydroxymethyl) -1,3-divinylbenzene is an important organic compound, and its storage conditions are very critical.
This compound should be stored in a cool and well-ventilated place. Because it is sensitive to heat, high temperature can easily change its properties and even cause dangerous reactions, so a cool environment can effectively maintain its chemical stability.
At the same time, it is necessary to ensure that the storage area is dry. The presence of moisture may promote reactions such as hydrolysis, which in turn affects its quality and purity. Humid environments can easily cause the compound to deteriorate with moisture and cannot meet subsequent use needs.
Furthermore, keep away from fire and heat sources. 5 + -Hg-2- (hydroxymethyl) -1,3-divinylbenzene has a certain flammability. In case of open flame and high heat energy, it will cause combustion and explosion. Therefore, staying away from fire and heat sources is an important measure to ensure storage safety.
In addition, it should be stored separately from oxidants and food chemicals, and mixed storage should not be avoided. Due to its active chemical properties, severe redox reactions may occur in contact with oxidants, while mixed storage with food chemicals may cause serious consequences such as accidental ingestion, threatening human health.
The container in which the substance is stored should be well sealed to prevent it from evaporating or reacting with external substances. Seal the container in time after use to avoid oxidation or absorption of moisture in the air due to long-term contact with the air, and maintain its original chemical properties. Regularly check the storage area to see if the container is damaged or leaked, so as to detect and deal with problems in time to ensure safe storage.

5-Hydroxy-2- (ethylamino) -1,3-dibenzofuran, this substance has unique physical and chemical properties. Its appearance is often crystalline solid, the texture is relatively fine, and it is quite stable at room temperature and pressure. The melting point is about [X] ° C. This temperature makes it change from solid to liquid in a specific environment, which brings specific requirements for related process operations.
In terms of solubility, it is difficult to dissolve in water because its molecular structure lacks a group that strongly interacts with water molecules, resulting in very low dispersion in water. However, it is soluble in some organic solvents, such as ethanol, dichloromethane, etc. In ethanol, by virtue of the van der Waals force between molecules and the possible weak interaction, it can be well dispersed and dissolved, which facilitates the preparation of solutions in organic synthesis and drug preparation.
From the perspective of chemical properties, its benzofuran structure endows it with certain aromaticity, making it able to participate in some typical reactions of aromatic compounds, such as electrophilic substitution reactions. Under suitable reaction conditions and catalysts, the hydrogen atoms on its benzene ring can be replaced by other functional groups, resulting in a series of derivatives with different biological activities and physical properties, which have potential applications in the field of medicinal chemistry. At the same time, the hydroxyl group and ethylamino group in the molecule also bring it unique reactivity, the hydroxyl group can undergo esterification, etherification and other reactions, and the ethylamino group can participate in nucleophilic reactions, etc. These reaction characteristics provide a rich way for its chemical modification and functionalization.
