What are the physical properties of 2-Cyano-5-Fluorobenzotrifluoride?
2-Cyano-5-fluorotrifluorotoluene is an important compound in organic chemistry. Its physical properties are unique and it has a wide range of uses in the chemical and materials fields.
Looking at its properties, it is mostly colorless to light yellow liquid under normal conditions, with a clear and transparent texture. It is like quiet lake water, free of impurities and pure.
When it comes to the melting point, it is about -30 ° C. Under this low temperature condition, the molecular arrangement tends to be orderly and the structural stability gradually strengthens, just like everything is dormant in winter, waiting for the opportunity to rejuvenate. The boiling point of
is between 190 and 192 degrees Celsius. When the temperature rises to this point, the molecular thermal motion intensifies, breaking free from constraints, and transitioning from liquid to gaseous state, such as a butterfly breaking the cocoon, opening a new state journey.
Its density is about 1.45g/cm ³, which is slightly higher than that of common liquids. When placed in a container, it seems to have a stable state and occupy space steadily.
In terms of solubility, it can be dissolved in most organic solvents, such as ethanol, ether, etc., as if it is integrated into the same group and coexists harmoniously with it, showing good compatibility, just like literati who speak freely among like-minded people and complement each other.
In terms of volatility, it has a certain degree of volatility. In the air, the molecules gradually spread, although quietly, it actually changes the surrounding environment, like a breeze, although invisible but influential.
The physical properties of 2-cyano-5-fluorotrifluorotoluene lay the foundation for its application in various fields, and it plays an indispensable role in organic synthesis, pharmaceutical research and development, etc., such as exquisite tools to help scientific research and industrial development.
Is 2-Cyano-5-Fluorobenzotrifluoride chemically stable?
The chemical properties of 2-cyano-5-fluoro-trifluorotoluene are quite stable under normal conditions. In its molecular structure, the presence of cyano (-CN), fluorine atom (-F) and trifluoromethyl (-CF) endows it with unique properties.
Cyanyl as a strong electron-absorbing group can redistribute the electron cloud density of the molecule and affect its chemical activity. However, due to conjugation with benzene ring, the energy of the system decreases, which enhances the overall stability. The fluorine atom has high electronegativity and high C-F bond energy, forming a stable structure, which makes the molecule resistant to external chemical reactions. Trifluoromethyl has a strong electron-absorbing induction effect, which further stabilizes the molecular structure.
In common chemical environments, 2-cyano-5-fluorotrifluorotoluene is not prone to spontaneous chemical reactions if there are no extreme changes in temperature and pressure, and no strong oxidizing agents, strong reducing agents or special catalysts. However, under specific conditions, such as high temperature, light or specific catalyst action, cyano groups can undergo hydrolysis, addition and other reactions; the benzene ring may also undergo electrophilic substitution reactions due to the influence of substituents. Overall, its chemical properties are relatively stable in general storage and conventional use scenarios.
What is the preparation method of 2-Cyano-5-Fluorobenzotrifluoride?
The preparation method of 2-cyano-5-fluorotrifluorotoluene is an important matter in the field of chemical synthesis. There are many methods, and the following is a common approach.
First, 2-methyl-5-fluorotrifluorotoluene is used as the starting material. This raw material is in a suitable reaction vessel and interacts with a suitable cyanide reagent under specific conditions. Cyanide reagents such as potassium cyanide (KCN) or sodium cyanide (NaCN), but such cyanides are highly toxic and should be used with extreme caution.
When reacting, many factors such as temperature, pressure and reaction time need to be controlled. The temperature is usually maintained within a certain range, or between 80 ° C and 120 ° C, and the pressure may vary from atmospheric pressure to several megapascals. The reaction time depends on the reaction process and monitoring results, and may take several hours to ten hours.
In order to make the reaction proceed more smoothly, it is often necessary to add appropriate catalysts. For example, some transition metal catalysts, such as copper salt catalysts, can promote the reaction of cyanyl groups to replace methyl groups.
During the reaction process, use monitoring methods, such as gas chromatography (GC) or liquid chromatography (HPLC), to closely observe the reaction process and product formation. When the reaction reaches the expected level, that is, the product content reaches the ideal value, follow-up treatment is carried out.
Subsequent processing involves the separation and purification of the reaction mixture. The product is first extracted with a suitable organic solvent to separate the product from the reaction system. It is further purified by distillation, recrystallization, etc., to obtain high-purity 2-cyano-5-fluorotrifluorotoluene.
Although this preparation method is common, each step requires fine operation to ensure that the reaction is carried out efficiently and safely, and finally a qualified target product is obtained.
What is the price range of 2-Cyano-5-Fluorobenzotrifluoride in the market?
In today's world, business conditions are unpredictable, and it is difficult to determine the price of 2-cyano-5-fluorotrifluorotoluene in the market. However, I can make a little speculation based on past business examples and changes in market conditions.
In the past, the price of these chemical materials often fluctuated due to various factors. First, the abundance and price of raw materials have a great impact on their price. If raw materials are easy to obtain and cheap, the price of 2-cyano-5-fluorotrifluorotoluene may stabilize and be slightly lower; if raw materials are scarce, the price will rise. Second, the skill of production is also the key. If the skill is not enough, the cost will be high, and the price will increase. Third, the supply and demand of the market, especially the price. If the demand exceeds the supply, the price will rise; if the supply exceeds the demand, the price will fall.
According to past business records, the price of such fine chemicals per kilogram may be between hundreds and thousands of yuan. However, this is only an approximate number. The actual price should vary depending on the actual situation of the market, the quantity of trade, the quality of the goods, and the region and season of the transaction. To know the exact price, you must consult all merchants and carefully observe the current market conditions before you can get it. Therefore, the price of 2-cyano-5-fluorotrifluorotoluene is difficult to determine. Only by studying the market conditions in detail can we obtain a more accurate price.
