4-Cyano-2-fluorobenzyl the physical properties of alcohol

4-Cyano-2-fluorobenzyl alcohol is one of the organic compounds. It has unique physical properties and is widely used in various fields of chemistry.

Looking at its physical state, at room temperature, 4-cyano-2-fluorobenzyl alcohol is mostly in a solid state, due to the intermolecular force. Its melting point is specific, about [specific melting point value], which is crucial when separating and purifying. When heated to the melting point, the substance gradually melts from the solid state to the liquid state, the intermolecular distance increases slightly, and the movement is more free.

When it comes to solubility, 4-cyano-2-fluorobenzyl alcohol has good solubility in organic solvents such as ethanol and ether. Due to the principle of "similar miscibility", its molecular structure and organic solvent molecules can form appropriate forces to dissolve. However, in water, its solubility is poor, and its molecular polarity matches the polarity of water molecules imperfectly, and the structures of cyano, fluorine atoms and benzyl alcohol affect its interaction with water molecules.

The color state of 4-cyano-2-fluorobenzyl alcohol is almost colorless to yellowish, and this color characteristic makes it impossible to introduce additional interference in some reactions or application scenarios that require color. Its odor is weak, not strong and pungent, and it has little impact on environmental odor during operation.

In addition, its density is also a specific value, about [specific density value]. This density characteristic provides an important basis for experimenters to grasp the distribution of components in the system when it involves mixing, stratification and other operations.

In summary, the physical properties of 4-cyano-2-fluorobenzyl alcohol, such as melting point, solubility, color state and density, together construct its unique "portrait" in the chemical world, laying the foundation for its application in many fields such as organic synthesis and drug development.

4-Cyano-2-fluorobenzyl chemical synthesis of alcohol

The chemical synthesis of 4-cyano-2-fluorobenzyl alcohol is an important research direction in the field of organic synthesis. To obtain this compound, several common paths can be followed.

First, 4-cyano-2-fluorobenzoic acid is used as the starting material. First, 4-cyano-2-fluorobenzoic acid is reacted with an appropriate reducing agent, such as lithium aluminum hydride (LiAlH), in an anhydrous organic solvent, such as anhydrous tetrahydrofuran (THF), at low temperature and in a nitrogen-protected atmosphere. Lithium aluminum hydride has strong reductive properties, and can reduce carboxyl (-COOH) to hydroxymethyl (-CH 2O OH) to obtain 4-cyano-2-fluorobenzyl alcohol. In this process, the reaction temperature and the amount of reducing agent need to be strictly controlled. Due to the high activity of lithium aluminum hydride, excessive dosage or improper reaction temperature, it is easy to cause side reactions such as excessive reduction.

Second, 4-cyano-2-fluorobrobenzyl can be started from. 4-cyano-2-fluorobrobenzyl reacts with metal magnesium in anhydrous ethyl ether to generate Grignard's reagent 4-cyano-2-fluorobenzyl magnesium bromide. Subsequently, the Grignard reagent is reacted with formaldehyde at low temperature, and then hydrolyzed with acid to obtain 4-cyano-2-fluorobenzyl alcohol. This route should pay attention to the anhydrous and anaerobic conditions during the preparation of Grignard reagent. Because Grignard reagent is sensitive to water and air, it is easy to decompose in contact with water or oxygen, and the reaction fails.

Furthermore, 4-cyano-2-fluorobenzaldehyde is used as the raw material. Use a mild reducing agent, such as sodium borohydride (NaBH), and carry out the reduction reaction in an alcohol solvent, such as methanol or ethanol. Sodium borohydride has high selectivity, can reduce aldehyde group (-CHO) to hydroxymethyl (-CH 2O OH), and efficiently prepare 4-cyano-2-fluorobenzyl alcohol. This method is relatively simple to operate, the reaction conditions are mild, and there are few side reactions. It is a common method for synthesizing this compound in the laboratory.

The above synthesis methods have their own advantages and disadvantages. In practical application, the most suitable method is selected to synthesize 4-cyano-2-fluorobenzyl alcohol according to factors such as raw material availability, reaction conditions, cost and yield.

4-Cyano-2-fluorobenzyl alcohol during storage and transportation

4-Cyano-2-fluorobenzyl alcohol is an organic compound, and many things need to be paid attention to during storage and transportation.

Primary storage environment. Be sure to place in a cool, dry and well-ventilated place. Because the substance may cause chemical reactions and deterioration if it is exposed to high temperature or humid environment. For example, high temperature or increase its volatilization, moisture or promote its hydrolysis and other reactions.

Secondary and packaging materials. Well-sealed and corrosion-resistant packaging should be selected. Glass containers or specific plastic containers are more suitable, which can effectively avoid material leakage and prevent adverse reactions with packaging materials. Like some metal packaging, it may chemically react with 4-cyano-2-fluorobenzyl alcohol, which affects its quality.

When transporting, caution is also required. Make sure that the transportation vehicle is clean and dry, and there are no other substances that may react with it. During transportation, severe vibration and collision should also be avoided to prevent material leakage caused by package damage.

Furthermore, whether it is storage or transportation, relevant regulations and safety standards must be strictly followed. Operators should be professionally trained and familiar with the characteristics of the substance and emergency treatment methods. In the event of an accident such as leakage, it is necessary to be able to take prompt and correct measures, such as evacuating personnel and cleaning up leaks, to ensure the safety of personnel and the environment from pollution.

What is the market price range for 4-Cyano-2-fluorobenzyl alcohol?

The market price range of 4-cyano-2-fluorobenzyl alcohol is difficult to say exactly. Market prices often change for many reasons, and they are still volatile and unpredictable.

First, the situation of supply and demand has a deep impact on its price. If the market demands 4-cyano-2-fluorobenzyl alcohol, but the supply is unsustainable, just like the seedlings of a long drought looking for sweet rain, its price will skyrocket; on the contrary, if the supply is full, the demand is cold as frost, and the price will also decline.

Second, the place and method of production are also related to its price. Different origins, depending on raw materials and processes, may have high and low costs. For example, in a place with exquisite skills and abundant raw materials, the output of 4-cyano-2-fluorobenzyl alcohol, or high quality, the price can also be viewed; while those with crude craftsmanship and ordinary raw materials, the price may be slightly lower.

Third, the state of market competition also affects its price. If there are many merchants competing to sell this product, it will be favored by customers, or the price will be reduced to attract customers; however, if the market is almost monopolized, the price will be easily manipulated between the hands.

Fourth, changes in the current situation and government regulations are also related to the price. If there is a lack of raw materials, transportation is blocked, or government restrictions, the cost can rise, and the price will be high.

Overall, the market price of 4-cyano-2-fluorobenzyl alcohol may fluctuate between tens of yuan and hundreds of yuan per kilogram, but this is only a rough estimate. The actual situation requires a detailed investigation of the current market situation and consultation with industry experts and suppliers to obtain a more accurate price.
