What is the main use of 7- (trifluoromethyl) -2-methylquinoline?
The light of 7- (Sanxiang ethyl) - 2 -ethylbenzoic acid, why is it mainly used in convergence? Among them, the light of Sanxiang ethyl and ethylbenzoic acid is important in many fields.
Let's talk about Sanxiang ethyl first, which is often used to reconcile various medicines in the art of Dan's preparation. As recorded in the "Compendium of Hundred Herbs", when some ointments are refined, adding an appropriate amount of Sanxiang ethyl can make all medicines blend more evenly and the medicinal effect is smoother. And in the refining method of Dan Sand, Sanxiang ethyl can help slow the hair of Dan Sand, without excessive medicinal power and hurting the viscera.
As for the light of ethylbenzoic acid, it is quite effective in the process of carving utensils and painting and coloring. In the technique of ceramic painting, the light of ethylbenzoic acid is used as a guide, and the color of the painting does not fade for a long time, and the color is more dazzling. In "Tiangong Kaiwu · Pottery", making good use of this light can make porcelain painting resemble heaven and come to life. In the art of jade carving, the light of ethylbenzoic acid can help craftsmen outline lines more accurately, making the beauty of jade show.
In pharmacological health care, the two can also be used. Sanxiang ethyl can channel meridians and collaterals, smooth qi and blood, and in some pills, it can be used as a medicine to lead and lead medicine to meridians. The light of ethylbenzoic acid, after being processed, may calm the mind and be occasionally used in health care prescriptions. In short, the light of 7 - (Sanxiang ethyl) -2 - ethylbenzoic acid has functions that cannot be ignored in many aspects such as medicine and technology.
What are the synthesis methods of 7- (trifluoromethyl) -2-methylquinoline?
To prepare 7- (triethyl) -2 -ethylbenzaldehyde, there are many ways to synthesize it.
First, it can be through the reaction of halogenated aromatics with alkylation reagents. First, take an appropriate halogenated benzene, such as bromobenzene, and make it react with Grignard reagents such as triethylmethylmagnesium halide to generate triethylmethyl-containing aromatics. Then, by Fu-gram acylation reaction, the acetyl group is introduced, and then the acetyl group is converted into an aldehyde group by specific oxidation means, such as mild oxidizing agent, and the final product can be obtained. This process requires attention to the precise control of the reaction conditions. The Grignard reaction requires an anhydrous and oxygen-free environment, and the choice and dosage of catalyst for the Fu-gram acylation reaction are also crucial.
Second, it can be started from benzaldehyde derivatives. First modify the benzaldehyde ring, and introduce ethyl and triethyl through alkylation. Suitable alkylation reagents can be selected to gradually complete the introduction of groups in the presence of appropriate catalysts. The positioning effect of the substituent needs to be considered in the reaction, and the reaction sequence needs to be reasonably planned to achieve the target substitution mode. And the post-reaction treatment steps also need to be carefully operated to ensure the purity and yield of the product.
Third, the reaction of utilizing alkenyl aromatics. First synthesize benzene derivatives containing appropriate alkenyl groups, such as allyl benzene, so that the alkenyl group reacts with specific reagents, and triethyl and ethyl are introduced to appropriately convert the double bond. Later, the aldehyde structure can be constructed by oxidizing and breaking the double bond. In this path, the selective control of the double bond reaction is the key point, and appropriate reagents and reaction conditions need to be selected to ensure that the desired product is generated rather than other by-products.
All these synthesis methods have their own advantages and disadvantages. In actual operation, it is necessary to choose carefully according to many factors such as the availability of raw materials, the difficulty of reaction conditions, and the yield and purity of the product.
What are the physical properties of 7- (trifluoromethyl) -2-methylquinoline?
The author of "Tiangong Kaiwu" was written by Yingxing in the Ming and Song Dynasties, and it is also detailed in the book of all kinds of technological products. As for the 7 - (triene methyl) - 2 - methylbenzaldehyde, although it was not what was mentioned in "Tiangong Kaiwu" at that time, it is inferred from today's reason that its physical properties are as follows.
Its color is a colorless to light yellow liquid at room temperature. Viewed under light, it can be seen that it is clear and slightly shiny, like morning light sprinkling on clear oil. Its taste may have a special fragrance, which is comparable to non-vulgar fragrance, similar to the smell of various aromatic alarms, but it also has its own unique characteristics. It is like being in a strange fragrance world. < Br >
Discuss volatility, because its structure contains specific groups, or has a certain volatility. In an open container, the amount gradually decreases over time, such as morning dew meeting the sun and Xi. Its density, compared to water, or slightly lighter, if placed in water, when floating on the water surface, like oil and water, clear and turbid self-separation.
Solubility is also an important physical property. In organic solvents, such as ethanol, ether, etc., or with good solubility, it can be miscible with solvents, just like water emulsion blend. However, in water, because it is an organic compound and contains hydrophobic groups, the solubility is not good, such as sand and gravel entering water, it is difficult to melt.
Melting point and boiling point should not be ignored. Melting point or lower, under normal low temperature environment, can still maintain liquid. Boiling point depends on its intermolecular force and structure, or in a certain temperature range, when heated to a specific temperature, it can be seen boiling, turning into gaseous rise.
What is the price of 7- (trifluoromethyl) -2-methylquinoline in the market?
There are seven - (triethyl) -di-ethylboronic acid in the market today. What is the price of it? I should carefully observe the situation of the city before I can know its exact price.
The price of all kinds of things in the city of Guafu often depends on many ends. First, the abundance of raw materials is also sorry. If the raw materials of triethyl and di-ethylboronic acid are easily available and abundant in the market, their price is flat; if the raw materials are rare and difficult to harvest, the price will be high. Second, it is difficult to make. If the method of making this medicine is simple and easy, and the labor cost is small, the price may be low; if the method of making it is difficult, it requires exquisite skills and a large amount of labor, and the price is high. Third, the amount of demand. If there are many people in the city, the supply is in short supply, and the price will rise; if there are few people in the city, the supply will exceed the demand, and the price will drop.
And it depends on the competition in the same industry. If the partners of this medicine want to sell their goods, they must compete at the price, and the price may be lowered; if there are few sellers, and they are only good at their city, the price may be independent and high. And the government of the imperial court and the changes of time may also be involved. The leniency of the government is related to taxation, and the tax and heavy price will also increase; the difference of time may have an impact on the production of raw materials, and the price can also change.
However, before I went into the market and looked at the situation in detail, it was difficult to determine the price of seven- (triethyl) -di-ethylboronic acid. You must go to the medicine shop in person and ask the merchants to check the pros and cons of their goods and the quantity. Only by taking into account the current situation can you know the approximate price.
How is the stability of 7- (trifluoromethyl) -2-methylquinoline?
The photostability of trialkyl methyl and dimethyl silicone oils is related to whether they can maintain their own structure and performance stability in light environment. Let's try to study these two, trialkyl methyl, which has a large number of methyl groups in its structure, and the spatial steric resistance effect is quite significant. This steric resistance is like a strong barrier, which can hinder chemical reactions caused by light. When light is irradiated, due to its structural characteristics, it is difficult for light energy to be smoothly transferred to key parts inside the molecule, which reduces the possibility of chemical bond breakage in the molecule, so the photostability is better.
In contrast, dimethyl silicone oils, their molecular backbone is composed of silica bonds, which have high bond energy and are not weak in their own stability. However, compared with trimethylmethyl, the side chain of dimethylsilicone oil is only methyl, and the spatial steric resistance is smaller. Under the action of light, light energy can more easily reach the interior of the molecule, causing changes in silica bonds or other chemical bonds, resulting in its photostability slightly inferior to that of trimethylmethyl.
The trimethylmethyl gene has a large spatial steric resistance, which is more resistant to light energy damage in the light environment, and has good photostability. Although dimethylsilicone oil has stable silica bonds, its spatial steric resistance disadvantage makes its photostability slightly weaker. In this way, the difference in photostability between the two is clearly discernible.
