7-(3-chloro-propoxy)-4-chloro-6-Methoxy-quinoline-3-carbonitrile

7 - (3 - cyanoethoxy) - 4 - cyanoethoxy - 6 - ethoxy - light - 3 - acetaldehyde is the main user, which has a wide range of uses.
Where 7 - (3 - cyanoethoxy), which is in the field of synthesis, can be used as a medium. If you want to create a high-quality molecule, it can use the cyanoethoxy group it contains to generate more subtle reactions. The cyanoactive group can be used to synthesize carboxylic acid compounds by hydrolysis, and can also be used to generate amino groups. This is especially important for amine compounds. The presence of ethoxy groups can affect the air resistance of molecules, the performance of molecules, and the performance of materials.
4-cyanide part also plays an important role in the process of multiplication. For the material science, it can be used for polymerization or modification. Because of its cyanide group, it can be formed together, which can effectively improve the mechanical properties and quality of materials. In the synthesis of some high-performance polymers, 4-cyanide can be used as an active group to promote the formation of molecules, which increases the stability of materials.
6-ethoxy group is very common in the physical and chemical fields. It can improve the lipid solubility of molecules, make it easier to penetrate biofilms, and increase the absorption of molecules. In the same way, it can reduce the density of the sub-cloud of molecules, affect the interaction between the target and the target, and change the activity of the molecules.
In this reaction system, light often acts as an introducer or catalyst. Light has sufficient energy, which can stimulate molecules to high energy and lead to photochemical reactions. For example, the reaction of free radicals in light can promote the synthesis of some common components, providing a new way for synthesis.
3-Acetaldehyde is an important synthetic raw material. It can be oxidized and reacted to obtain acetic acid, which is widely used in chemical industries, such as acetic acid, synthetic flavors, etc. Acetaldehyde can also be reacted to the original to obtain ethanol. Ethanol is a commonly used solution and is indispensable in fuels, wines, etc. In addition, acetaldehyde can generate a series of active compounds with different functions, which are useful in flavors, flavors, and other fields.

To prepare a compound of 7- (3-cyanoethoxy) -4-cyano6-ethoxy with 3-acetamide as the raw material, the following ancient method can be used.
First take an appropriate amount of 3-acetamide and place it in a clean kettle. Using the ancient method, control its temperature and duration, and apply specific conditions to make 3-acetamide start a certain transformation first. This transformation may involve changes in molecular rearrangement, bond breaking and bonding, so that the structure of acetamide is gradually required.
Then, cyanide-containing reagents are introduced. Cyanyl activity is quite strong, and under the action of established temperature and humidity and catalytic agents, it can be cleverly combined with the first converted products. Or due to the attraction of electric charges and the matching of orbitals, the cyanyl group is precisely connected to a specific check point, so it becomes a cyanide-containing intermediate, that is, 4-cyano3-acetamide derivatives.
Furthermore, ethoxy is introduced into the intermediate. This step requires careful selection of agents. For example, using ethoxylated reagents, in accordance with ancient regulations, under a suitable acid-base environment, the ethoxy group can be combined with the intermediate. The degree of acid and base is related to the back and rate of the reaction, and must be precisely controlled. In this way, 4-cyanogen-6-ethoxy-3-acetamide products can be obtained.
Then, through a series of modification methods, such as deprotecting groups, functional group conversion, etc. When deprotecting groups, a mild agent is selected to avoid damaging the main structure of the molecule. Functional group conversion is cleverly changed according to the desired final product structure.
Finally, through multiple purification techniques, such as recrystallization, distillation, extraction, etc. During recrystallization, a suitable solvent is selected to allow the product to crystallize out of it to remove its impurities; distillation is used to fractionate the product according to the difference in boiling point; extraction is used to extract pure 7- (3-cyanoethoxy) -4-cyano6-ethoxy-3-acetamide due to the difference in solubility of the solvent. This compound can be prepared by combining various ancient methods.

The physical properties of this substance are as follows:
Its shape is either crystalline or powder, depending on the environment and the preparation method. The color is often close to colorless or very light, mostly white, pure in appearance, without variegated patches.
Smell it, the gas is very small, hardly noticeable, no pungent or foul smell, if any, it is only a very light special smell, and cannot be felt without smelling.
In terms of its melting and boiling point, the melting point is quite high, and a specific high temperature is required to melt it into a liquid state. This is due to the strong intermolecular force and relatively stable structure; the boiling point is also high, and if you want to vaporize it, you need to apply a higher temperature to break the binding of its molecules.
The solubility of this substance in water is not good. Water is a polar solvent, and the molecular polarity of this substance is relatively weak. According to the principle of "similar miscibility", it is difficult to dissolve in water. However, in organic solvents, such as ethanol, acetone, etc., it has a certain solubility. The polarity of organic solvents is more matched with this substance, and a certain interaction can be formed between molecules to help it dissolve. < Br >
Its density is slightly higher than that of water. If placed in water, it will mostly sink to the bottom of the water. And the hardness of this material is moderate, not as strong as gold and stone, nor as soft as plaster, so it has a certain sense of resistance when pressed.
Its stability to light and heat is acceptable. Under normal photothermal conditions, it can maintain the stability of its structure and properties. However, if the photothermal is too strong, it may also cause it to decompose and deteriorate.

7- (3-chloro-methylhydroxyl) -4-chloro-6-methylhydroxyl-light-3-methyl ether, the chemical properties of this substance are as follows:
First, the presence of chlorine atoms gives it a certain activity. Chlorine is a highly electronegative element, which can reduce the electron cloud density of carbon atoms connected to it in the molecule. Take 3-chloro-methylhydroxyl and 4-chlorine as examples, which can participate in nucleophilic substitution reactions. Because the chlorine atom can be used as a leaving group, when there is a nucleophilic attack, the nucleophilic reagent will replace the position of the chlorine atom, such as reacting with reagents containing hydroxyl, amino and other nucleophilic groups.
Methyl hydroxyl moiety, the hydroxyl group has polarity and can participate in the formation of hydrogen bonds. This property affects its physical properties, such as boiling point and solubility. And the hydroxyl group can undergo oxidation reaction under certain conditions, and can be oxidized to oxygen-containing functional groups with higher valence states such as aldehyde group and carboxyl group. When the hydroxyl group interacts with a suitable oxidant, such as potassium permanganate and other strong oxidants, the oxidative transition can gradually occur. The effect of
light on this compound cannot be ignored. Under light conditions, photochemical reactions may be initiated, and molecules are in an excited state after absorbing photon energy, and then reactions such as chemical bond breaking and rearrangement occur. This process may generate new active intermediates, which promote the reaction to proceed in different directions.
The structural part of methyl ether has relatively stable chemical properties, but under specific conditions such as strong acids, ether bonds can be broken. The oxygen atom of methyl ether has a certain lone pair of electrons, which can bind to Lewis acids such as protons, thereby weakening the ether bond, and finally breaking to form corresponding alcohols.
Overall, the compound exhibits a variety of chemical properties due to the interaction of different functional groups, and various characteristic chemical reactions can occur under different reaction conditions.

Today I have a question, what is the price of methyl ether? Because of the chemical industry, its price often varies with time, place, and quality, and it is difficult to know for sure.
Looking at "Tiangong Kaiwu", although it is detailed in all kinds of technical products, but at that time the chemical industry was not developed, and the name of methyl ether was not heard, and there is no mention of its price. In today's world, science and technology are new, and methyl ether is widely used, involving fuels, chemical raw materials, etc.
Its price is in the market, subject to supply and demand, costs, and policies. Those who supply and demand, if there is a lot of demand and a lack of supply, the price will rise; otherwise, the price will be depressed. Costs, raw materials, production, and transportation are all included. If the price of raw materials is high, or the production is complicated and energy-consuming, or the transportation is difficult and difficult, the price will increase. Policy makers, government regulation and subsidies also have an impact. Encouraging its production and use, the price may be stable or reduced; otherwise, the price may rise.
In today's market, the price of methyl ether fluctuates every time. Usually, it is between thousands of yuan per ton. In the event of a sudden shortage of raw materials, a surge in demand, the price may rise sharply; if overcapacity and low demand, the price may also drop sharply. To know the exact price, when you want to study the current market situation, consult merchants, brokers, or check industry newspapers and information stations, you can get a close figure.
