First of all, its appearance is mostly colorless to slightly yellow transparent liquid under normal conditions, and it looks clear, like clear water in a mirror, without obvious impurities. Its color is pure, like the pure light at dawn.

The melting point is about -20 ° C. Under this temperature, it may condense into a solid state, like a sleeping crystal, crystal clear.

And the boiling point is roughly between 190-195 ° C. When the temperature reaches this point, it turns from liquid to gaseous state, curling and rising, like clouds and mist.

When it comes to density, it is about 1.35-1.40 g/cm ³, which is heavier than water and placed in water, such as a stone sinking abyss.

This substance also has characteristics in terms of solubility. It can be slightly soluble in water, but it can be miscible in most organic solvents, such as ethanol, ether, acetone, etc., just like a fish in water, which is fused infinitely.

Its smell is light and slightly fragrant, not pungent, like a wisp of fragrance in the spring breeze, and it is slightly pleasant to smell. < Br >
and has a certain volatility. In an open environment at room temperature, its molecules gradually escape into the air, such as light smoke, but the volatilization rate is not extremely fast, which is a relatively gentle process.

These physical properties are of great significance in many fields such as chemical industry and pharmaceutical synthesis, laying the foundation for their application.

3-Trifluoromethyl-4-fluorobenzyl the chemistry of alcohol

3-Trifluoromethyl-4-fluorobenzyl alcohol, this is an organic compound. It is active and has unique physical and chemical properties.

Looking at its physical properties, under room temperature and pressure, it is mostly colorless to light yellow liquid with weak odor. Due to the large number of fluorine atoms in the molecule, its physical constants such as boiling point and melting point are different from ordinary benzyl alcohol compounds. The high electronegativity of fluorine atoms makes the intermolecular force special, which in turn affects the melting boiling point.

As for the chemical properties, the benzyl alcohol structure in this compound allows it to participate in many typical reactions of alcohols. For example, it can be esterified with acids, and under the action of catalysts, it can react with carboxylic acids to form corresponding esters. This reaction is commonly used in the field of organic synthesis of fragrances, pharmaceutical intermediates, etc. At the same time, the hydroxyl group can be oxidized, weak oxidants can oxidize it to aldehyde, and strong oxidants can further oxidize it to carboxylic acid.

And because its molecule contains trifluoromethyl and fluorine atoms, it gives it some special chemical properties. Trifluoromethyl has strong electron absorption, which can affect the electron cloud density of the benzene ring, change the electrophilic substitution reaction activity on the benzene ring, and the substitution position is also affected. The introduction of fluorine atoms enhances molecular stability and fat solubility. In the field of medicinal chemistry, such structures often improve drug biological activity, metabol

In organic synthesis, 3-trifluoromethyl-4-fluorobenzyl alcohol is an important intermediate. Through its different reactions, a variety of fluorinated organic compounds can be constructed, which are widely used in medicine, pesticides, materials science and other fields. It provides the possibility for the creation of new functional materials and high-efficiency and low-toxicity drugs.

3-Trifluoromethyl-4-fluorobenzyl the synthesis of alcohol

The synthesis method of 3-trifluoromethyl-4-fluorobenzyl alcohol has been recorded in ancient books. One method can be started with 3-trifluoromethyl-4-fluorobenzoate ethyl ester. The ester is placed in a reactor, an appropriate amount of tetrahydrofuran is used as a solvent, metal lithium aluminum hydride is added, and it is slowly warmed to a suitable temperature, about 40-60 degrees Celsius, and continuously stirred to make it fully reacted. In this process, the ester group is gradually converted into an alcohol hydroxyl group under the strong reduction of lithium-aluminum hydride. After several times of reaction, when the reaction is complete, the reaction solution is carefully treated with dilute acid, and then extracted, separated and purified to obtain 3-trifluoromethyl-4-fluorobenzyl alcohol.

There are also those who use 3-trifluoromethyl-4-fluorobrombenzyl as raw materials. First mix it with an appropriate amount of ulotropine, use acetonitrile as a solvent, and react at about 50-70 degrees Celsius under mild heating conditions for a period of time to generate the corresponding quaternary ammonium salt. Subsequently, the quaternary ammonium salt is hydrolyzed with dilute hydrochloric acid, the hydrolysis is completed, and the alcohol can be obtained after neutralization in alkali solution, extraction, distillation and other steps.

Furthermore, 3-trifluoromethyl-4-fluorobenzaldehyde is used as the starting material. Add an appropriate amount of sodium borohydride to the reaction system, use methanol or ethanol as the solvent, and stir the reaction at room temperature or slightly higher than room temperature, about 25-40 degrees Celsius. Sodium borohydride can efficiently reduce aldehyde groups to alcohol hydroxyl groups. After the reaction is completed, the target product 3-trifluoromethyl-4-fluorobenzyl alcohol can be obtained through simple post-treatment such as filtration, concentration, and purification. All kinds of synthetic methods have their own advantages and disadvantages, and they need to be used according to the specific situation.

What is the price range of 3-Trifluoromethyl-4-fluorobenzyl alcohol in the market?

The price of Wuguan Market is volatile and varies from time to place. As for the market price of 3-trifluoromethyl-4-fluorobenzyl alcohol, it is also difficult to determine.

Its price is often influenced by various factors. The first to bear the brunt is the cost of raw materials. If the raw materials required for its preparation are difficult to obtain, or there is a shortage of supply, the price will rise; on the contrary, if the raw materials are abundant, the price is expected to stabilize or drop slightly.

Furthermore, the skill and scale of production also have an impact. If the process is refined, it can be efficiently produced, the scale is large, and the cost is shared, the price may be close to the people; however, if the technology is difficult and the production is limited, the cost will be high, and the price will be expensive.

The supply and demand situation of the market is more critical. If this product is in the market, the demand is strong, and the supply is limited, the merchant will raise the price to pursue profit; if the supply exceeds the demand, the price will fall in order to sell the inventory.

There are side reasons such as policies and regulations, transportation costs, etc. Policies encourage production, or can reduce costs, affecting the price; transportation is long and dangerous, and the cost increases greatly, which will also cause its price to be high.

To sum up, in order to know the exact market price range of 3-trifluoromethyl-4-fluorobenzyl alcohol, it is necessary to carefully investigate the current raw materials, processes, supply and demand, and various related conditions. With the current situation, it is difficult to determine the exact price, which is mostly between market fluctuations, high or low. Practitioners and purchasers need to pay attention to the changes in the market situation in real time.
