2,3,4,5,6 - What are the physical properties of Pentafluorobenzyl alcohol

2% 2C3% 2C4% 2C5% 2C6-pentafluorobenzyl alcohol, the physical properties of this substance are quite critical. Under normal temperature and pressure, it mostly appears as a colorless to light yellow liquid, which is clear and translucent. It has a certain degree of volatility and can evaporate slowly in the air, but the volatilization rate is not very fast.

When it comes to the boiling point, it is about 180-190 ° C. This boiling point allows it to be converted into a gaseous state under normal heating conditions. The melting point is about -10 ° C, which means that it can be condensed into a solid state at an environment slightly lower than normal temperature.

The density of pentafluorobenzyl alcohol is slightly higher than that of water, about 1.5 to 1.6 g/cm ³. When mixed with water, it can be seen that it sinks to the bottom. In terms of solubility, it is slightly soluble in water, but easily soluble in many organic solvents, such as ethanol, ether, acetone, etc. In organic solvents, it can be well dispersed to form a uniform solution system.

In addition, the substance also has certain hygroscopicity. If exposed to high humidity air, it can absorb part of the water vapor, resulting in an increase in its own mass and a slight change in its properties. These physical properties are of great significance in their storage, transportation, and application in various chemical reactions, and are relevant to the feasibility and safety of their experimental operations.

2,3,4,5,6 - What are the chemical properties of Pentafluorobenzyl alcohol

2% 2C3% 2C4% 2C5% 2C6 - Pentafluorobenzyl alcohol is an organic compound. It has unique chemical properties. From the structural point of view, there is a hydroxymethyl group attached to the benzene ring, and the adjacent, intermediate and opposite positions of the benzene ring are replaced by fluorine atoms.

The physical properties of this compound are mostly liquid at room temperature, with a certain degree of volatility and a special odor. In terms of solubility, it is soluble in organic solvents such as ethanol and ether, but its solubility in water is limited. Because of its molecular structure, the benzene ring and fluorine atoms give it a certain hydrophobicity, and although the hydroxymethyl group is hydrophilic, it is not enough to greatly improve its solubility in water. < Br >
Chemically, because it contains hydroxyl groups, many reactions related to hydroxyl groups can occur. If esterification can occur with carboxylic acids, under acid catalysis, the hydroxyl group dehydrates and condenses with the carboxyl group to form corresponding esters. At the same time, the hydroxyl group can be oxidized, and if it encounters a strong oxidant, it can be oxidized to an aldehyde group or even a carboxyl group. Furthermore, due to the presence of fluorine atoms on the benzene ring, the electron cloud density of the benzene ring is reduced, and the electrophilic substitution reaction activity is weakened, which is different from the electrophilic substitution reaction of general benzene derivatives. The fluorine atom also makes the compound have certain stability. Under many chemical reaction conditions, its structure is not easily destroyed, and it may have special uses in the fields of organic synthesis and materials science.

What are the synthesis methods of 2, 3, 4, 5, 6 - Pentafluorobenzyl alcohol

2% 2C3% 2C4% 2C5% 2C6 - Pentafluorobenzyl alcohol, that is, 2,3,4,5,6 - pentafluorobenzyl alcohol, is synthesized as follows:

First, it can be obtained by reacting 2,3,4,5,6 - pentafluorobenzyl acid with a suitable reducing agent. In the past, metal hydrides such as lithium aluminum hydride (LiAlH) were mostly used as reducing agents. This reaction needs to be carried out in an anhydrous and low temperature environment, because lithium aluminum hydride reacts violently with water, and the reaction temperature has a great influence on the purity and yield of the product. First, dissolve 2,3,4,5,6 - pentafluorobenzyl acid in an anhydrous organic solvent such as anhydrous ether or tetrahydrofuran, and then slowly add lithium aluminum hydride under low temperature cooling and stirring. After the reaction is complete, 2, 3, 4, 5, 6-pentafluorobenzyl alcohol can be obtained by hydrolysis, extraction, distillation and other steps.

Second, use 2, 3, 4, 5, 6-pentafluorobenzyl as raw material to react with nucleophilic reagents. An aqueous solution or an alcohol solution of potassium hydroxide or sodium hydroxide can be used as a nucleophilic reagent, and this reaction is relatively mild. At an appropriate temperature and reaction time, 2, 3, 4, 5, 6-pentafluorobenzyl bromide reacts with nucleophilic reagents, and the bromine atom is replaced by a hydroxyl group to generate 2, 3, 4, 5, 6-pentafluorobenzyl alcohol. After the reaction is completed, the pure product can be obtained by neutralization, separation and purification.

Third, by electrochemical synthesis. Using an electrolyte containing 2,3,4,5,6-pentafluorobenzaldehyde, under specific electrode materials and electrochemical conditions, a reduction reaction is carried out to generate 2,3,4,5,6-pentafluorobenzyl alcohol. This method is green and environmentally friendly, does not require the use of a large number of chemical reagents, but requires very high control of equipment and reaction conditions. Parameters such as electrode potential, current density, and electrolyte composition need to be precisely regulated to achieve the desired reaction effect.

2, 3, 4, 5, 6 - What is the price range of Pentafluorobenzyl alcohol on the market?

2% 2C3% 2C4% 2C5% 2C6 - Pentafluorobenzyl alcohol, that is, 2, 3, 4, 5, 6 - pentafluorobenzyl alcohol, the price range of this product in the market is difficult to determine. The fluctuation of its price often depends on many factors.

First, the state of supply and demand. If there are many people who want it, and the supply is small, the price will necessarily rise; on the contrary, if the supply exceeds the demand, the price will fall. Second, the manufacturing cost is also the key. The price of raw materials, the method of manufacturing, and the cost of energy consumption all affect its cost, which in turn affects the selling price. Third, the competitive situation of the city cannot be ignored. There are many people in the same industry, in order to compete for the market share, or there may be a price reduction; if there is a single company, or there is a monopoly, the price can be set by yourself.

In the ancient books, there are few accurate records of the price of this specific product in the market. However, looking at the price rules of similar fine chemical products, if 2,3,4,5,6-pentafluorobenzyl alcohol is of high purity and high quality, the price per gram may range from tens to hundreds of yuan. If the purity is slightly lower and the application range is limited, the price may be slightly reduced, between a few yuan and tens of yuan per gram. But this is only speculation. The actual price needs to be consulted with the chemical product supplier in detail, depending on the current market conditions and product specific specifications.
