2-(trifluoromethyl)quinoline-4-carbonitrile

(Sanxiang methyl) square fire and tetramethyl ether are both used in Taoist alchemy, and their main uses are of great significance in alchemy practice.
Husband (Sanxiang methyl) square fire, within the elixir cauldron, can reconcile the properties of various medicines. In the art of alchemy, all medicines are combined, each has its own nature, either dry or cold, or rigid or soft. (Sanxiang methyl) square fire, with its unique ability, can make all medicines blend together, remove its bias, and store its essence, making the nature of pills more peaceful and pure, so as to achieve the purpose of serving the body and mind and prolonging life.
As for tetramethyl ether, in the process of alchemy, it is often the key to catalytic guidance. Alchemy cultivation pursues the condensation and sublimation of the essence of medicine, and tetramethyl ether can help the polymerization of medicinal power, leading it to follow the right path. When the medicinal pill is formed, tetramethyl ether promotes the condensation of medicinal power, making the internal structure of the medicinal pill more compact and orderly. In this way, the effect of the medicinal pill is more significant.
In terms of Taoist alchemy, the two complement each other. (Sanxiang methyl) Square fire lays the foundation of the medicinal pill, making the medicine and its sex pure; tetramethyl ether helps the medicinal pill to sublimate and improve the efficacy of medicinal power. Both are indispensable for refining high-quality medicinal pills, carrying the ancient people's unremitting pursuit and wisdom exploration for longevity and long-term vision, physical and mental sublimation, and shining a unique light in the long road of alchemy practice, preserving precious clues and wisdom crystallization for future generations to study ancient alchemy culture and Taoist practice concepts.

To prepare di- (triethylphenyl) propane-4-acetaldehyde, the method is as follows:
The first step is the Fu-gram reaction. Starting with benzene and propylene, under the catalysis of Lewis acids such as aluminum trichloride, the double bonds in propylene are attracted by the electron cloud of the benzene ring, and the electrophilic addition occurs to produce cumene. This step requires controlling the reaction conditions, such as temperature and catalyst dosage, to avoid the formation of multiple substituents. Under specific conditions, cumene can further react with halogenated ethylbenzene in a similar catalytic environment to construct a di- (triethylphenyl) propane structural framework. Later, by suitable oxidation means, the carbon-hydrogen bond at a specific position is converted into an aldehyde group, so that the partial structure of acetaldehyde in the target product can be obtained.
Secondly, the Grignard reagent method can be The Grignard reagent is prepared by suitable halogenated aromatics and magnesium chips in anhydrous ethyl ether and other inert solvents, and then reacts with carbonyl compounds containing the corresponding structure to grow the carbon chain and construct the basic structure of di- (triethylphenyl) propane. After the reaction is completed, the product is oxidized and modified through post-treatment steps such as hydrolysis, and then the specific group is converted into an aldehyde group to meet the structural requirements of the target product. This process requires strict requirements for the reaction system to be anhydrous, otherwise the Grignard reagent is easy to decompose.
In addition, the addition method of alkynyne is also feasible. Select suitable alkynyne compounds, use their unsaturated bonds with reagents containing benzene rings and specific functional groups, and use transition metal catalysis to build a carbon skeleton of the target product through addition reaction. By selecting different active reagents and regulating reaction conditions, precise control of the position of functional groups and reaction selectivity is achieved. Subsequent functional group conversion is carried out on the obtained product, and the specific group is modified into acetaldehyde structure, and then the synthesis of di- (triethylphenyl) propane-4-acetaldehyde is completed.
All synthesis methods have advantages and disadvantages, and need to be carefully selected according to actual conditions, such as raw material availability, cost, reaction difficulty and product purity requirements.

Triethylborane is a colorless to light yellow liquid with a specific odor. It is highly flammable and can spontaneously ignite when exposed to air, due to its high chemical activity. Its boiling point is quite low, about 95 ° C, and its relative density is less than that of water.
Ethyl ether is a colorless and transparent liquid at room temperature and pressure, with a special and volatile odor. Its boiling point is about 34.6 ° C, which is highly volatile and has a high vapor pressure. Slightly soluble in water, miscible with most organic solvents. Flammable and narcotic, it is easy to burn and explode when exposed to open flames and hot topics.
The physical properties of the two are different, due to the molecular structure and chemical bond properties. The high activity of triethylborane is due to the special electronic structure of boron atoms, which makes it easy to react with oxygen in air and spontaneously ignite. The volatility and solubility of ethyl ether are determined by its intermolecular forces and polarity, and the existence of ether bonds gives it special physicochemical properties.

The physical properties of trialkyl methyl ether light and ethyl ether are quite important in the academic world.
Trialkyl methyl ether light, at room temperature, is mostly gaseous, but it is also significantly affected by external conditions. If the temperature drops and pressure rises, it may be transferred to a liquid state. This substance has a specific smell and is slightly irritating, so you need to be careful when smelling. It is flammable, and it can easily cause combustion when exposed to open flames and hot topics, and can even cause explosions. When storing and using it, be careful to prevent fire sources. Its chemical activity is not weak, and it can react with many reagents. For example, when encountering strong oxidants, it can often induce violent reactions. When operating, be careful and follow the procedures.
As for ethyl ether, it is a colorless and transparent liquid at room temperature and pressure. It is highly volatile and can quickly diffuse in the surrounding space. Its smell is fragrant, but if inhaled in excess, it is also harmful to the human body. The boiling point of ethyl ether is low, and it is easy to vaporize when heated. This property is often used in distillation, separation and other operations. Its chemical properties are relatively stable, but under certain conditions, it is not static. In case of strong acids and alkalis, hydrolysis reactions can occur, and the molecular structure is destroyed to form other substances. And ethyl ether is also flammable. Although the ignition point is slightly higher than that of some similar substances, it is still flammable. In production and storage, fireworks are strictly prohibited.
These two are widely used in chemical industry, scientific research and other fields. However, due to their physical characteristics, when using them, it is necessary to know their properties in detail and strictly abide by safety regulations in order to achieve the expected effect and ensure the safety of personnel and the environment.

In today's world, there are many trade routes, and the nobility and inferiority of things often vary from time to time, and it varies from city to city. As for the price of (triethyl) propane fluorescence and 4-ethylnaphthalene, it is difficult to determine.
Looking at the law of the market, supply and demand are related. If there are many people who want it, and there are few people who supply it, the price will increase; if the supply exceeds the demand, the price will be reduced. (Triethyl) propane fluorescence is used in various wonderful techniques, such as the production of luminous light and the method of analysing matter. Its price is also related to the materials used, the skills of creation, and the needs of the city. If the material is rare and difficult, but the use of it is wide, the price will be high; if the material is wide and easy, and the demand is limited, the price will be flat.
4-Ethylnaphthalene also has its uses, either as the basis of medicine or as a supplement to incense. The change in its price also follows the principle of supply and demand. If there is a lot of competition for medicine, the incense industry will bid for it, but if there are few products, the price will be high; if there is a lot of production, but there are few users, the price will not rise.
The situation in the world also has an impact. The politics of the four parties may be rewarded or limited; the trade of neighboring countries may be smooth or blocked. If there are political awards, there will be a large number of producers, and the price will stabilize or drop; if there are political restrictions, there will be a small number of producers, and the price will be unpredictable. If the trade is smooth, the goods will pass from north to south, and the price will be even; if the trade is blocked, the price will be abnormally high and abnormally low.
Therefore, if you want to know the price of (triethyl) propane fluorescence and 4-ethylnaphthalene in the market, you should study the changes in supply and demand, and observe the trend of political and trade. It is difficult to determine its value.
