What are the physical properties of 5- (Chloromethyl) -1,2,3-trifluorobenzene

5 - (chloromethyl) - 1,2,3 -trifluorobenzene, is one of the organic compounds. Its physical properties are as follows:

Under normal temperature and pressure, it is often colorless to light yellow transparent liquid, just like clear water, clear and bright. Its color is light, almost nothing, or because of some impurities, it is slightly yellowish, like the first light of morning, yellowish and light.

Smell its smell, often with a special irritating smell, this smell is like a mountain on the back, directly piercing the nostrils, making people feel slightly uncomfortable. This irritating smell may be derived from the characteristics of chloromethyl and trifluorophenyl in its molecular structure. < Br >
As for its boiling point, it is about 150-160 ° C. When heated to this temperature range, the compound melts into water like ice, converts from liquid to gaseous state, and rises away. The value of the boiling point is determined by the magnitude of the intermolecular force, and the intermolecular force just causes the boiling point to be in this range.

The melting point is about -30 ° C. When the temperature drops, the liquid that originally flowed will stop water and turn into ice, solidify into a solid state, and the molecular arrangement will gradually become orderly from disorder.

Its density is heavier than that of water, about 1.4-1.5 g/cm ³. When placed in water, it will sink straight down like a rock. Due to the relatively large atomic mass of chlorine and fluorine atoms in the molecule, their unit volume mass is greater than that of water.

In terms of solubility, organic solvents, such as ethanol, ether, acetone, etc., are quite soluble, like a fish in water, miscible; however, in water, it is difficult to dissolve, just like oil and water separated, distinct. This is because the compound is non-polar or weakly polar, while water is a strong polar solvent, according to the principle of similar miscibility, so it is difficult to dissolve.

These physical properties are of great significance in many fields such as organic synthesis and chemical production, and are related to the choice of reaction conditions, the separation and purification of products, and other matters.

What are the synthesis methods of 5- (Chloromethyl) -1,2,3-trifluorobenzene

There are several common methods for the synthesis of 5- (chloromethyl) -1,2,3-trifluorobenzene.

One is obtained by chloromethylation with 1,2,3-trifluorobenzene as the starting material. In this reaction, polyformaldehyde and hydrogen chloride can be selected as chloromethylation reagents. In the presence of suitable catalysts, such as anhydrous zinc chloride, 1,2,3-trifluorobenzene reacts with chloromethylation reagents at specific temperatures and reaction times. During the reaction, close attention should be paid to the control of the reaction temperature. Excessive temperature or increased side reactions will affect the purity and yield of the product.

Second, a specific substituent can be introduced into the benzene ring to construct an intermediate with suitable functional groups, and then converted into the target product through a series of reactions. For example, a group that can be further converted into chloromethyl groups is introduced first, and after multi-step reaction modification, 5- (chloromethyl) -1,2,3-trifluorobenzene is finally formed. Although this path is slightly complicated, under specific conditions, it may improve the selectivity and purity of the product.

Third, fluorohalogenated aromatics are also used as raw materials to achieve synthesis by nucleophilic substitution reaction with chloromethyl-containing reagents. In this process, careful selection of reaction solvents and bases is required to promote the smooth progress of the reaction. Different solvents and bases have significant effects on the reaction rate, selectivity and product yield.

When synthesizing 5- (chloromethyl) -1,2,3-trifluorobenzene, the most suitable synthesis method should be comprehensively considered and selected according to many factors such as actual demand, raw material availability and cost, in order to achieve efficient, economical and environmentally friendly synthesis goals.

What to pay attention to when storing and transporting 5- (Chloromethyl) -1,2,3-trifluorobenzene

5- (chloromethyl) - 1,2,3-trifluorobenzene is an organic chemical, and many key points need to be paid attention to when storing and transporting it.

In terms of storage, the first choice is the environment. It should be found in a cool, dry and well-ventilated place. Because the chemical is quite sensitive to temperature and humidity, high temperature can easily increase its chemical reactivity, or cause adverse reactions such as decomposition and polymerization; high humidity environment may make it damp and affect quality. This is the basic requirement for storage, just like the cornerstone of building a house.

In addition, storage containers are also extremely critical. Choose corrosion-resistant materials, such as specific glass containers or high-quality plastic containers. Because it contains chlorine, fluorine and other elements, it is chemically active, and ordinary material containers are prone to corrosion, resulting in damage to the container or leakage of substances. And the container must be tightly sealed to prevent contact with air, oxygen, moisture in the air, etc., or reaction with the substance.

During transportation, the packaging must be stable and tight. To avoid damage to the container due to vibration and collision during transportation. It should be operated in accordance with the transportation specifications of hazardous chemicals, and professional transportation personnel and equipment should be equipped. Transportation personnel need to be familiar with the characteristics of the substance and emergency treatment methods. In case of unexpected situations, they can respond quickly and properly.

In addition, whether it is storage or transportation, relevant laws and regulations and safety standards must be strictly followed. Make detailed records, such as storage time, quantity, transportation route and other information for traceability and management. In this way, the safety and stability of 5- (chloromethyl) -1,2,3-trifluorobenzene during storage and transportation can be ensured.
