What are the physical properties of 3-Cyano-4-Fluorobenzotrifluoride~ Alpha, Alpha, Alpha, 6-Tetrafluoro-M-Tolunitrile
3-Cyano-4-fluorotrifluorotoluene (3-Cyano-4-Fluorobenzotrifluoride), also known as α, α, α, 6-tetrafluoro-m-toluonitrile (Alpha, α, α, 6-Tetrafluoro-M-Tolunitrile), is an important intermediate in the field of organic synthesis. Its physical properties are as follows:
- ** Appearance and Properties **: Usually colorless to light yellow liquid, under normal temperature and pressure, the visual appearance is clear and fluidity is good. This appearance characteristic helps to intuitively judge its state in actual operation, which is convenient for controlling the reaction process.
- ** Melting point and boiling point **: The melting point is about -20 ° C, and the boiling point is roughly in the range of 180-182 ° C. The relatively low melting point indicates that the substance can be converted from solid to liquid at a lower temperature; the relatively high boiling point means that a higher temperature is required to vaporize it. This property is of great significance in the process of separation and purification. According to its boiling point characteristics, it can be effectively separated from other substances by means of distillation.
- ** Density **: The density is about 1.42 g/cm ³, which is higher than the density of water at 1.0 g/cm ³, so the substance will sink to the bottom of the water. This characteristic is crucial in operations involving liquid-liquid separation, and can be used to select suitable separation methods and equipment.
- ** Solubility **: Soluble in common organic solvents, such as dichloromethane, chloroform, ether, etc., but insoluble in water. This solubility characteristic makes it possible to construct a homogeneous reaction system with the help of suitable organic solvents in organic synthesis reactions, thereby promoting the smooth progress of the reaction; at the same time, the insoluble property of water also provides convenience for the separation of the substance from the aqueous phase system.
- ** Vapor Pressure and Volatility **: At room temperature, the vapor pressure is low and the volatility is relatively weak. This means that the substance evaporates from liquid to gaseous at a relatively slow rate at room temperature, which reduces the risk of its diffusion in the air to a certain extent and is conducive to the safety of storage and operation.
- ** Stability **: Under normal storage and use conditions, it has certain chemical stability. However, it should be noted that due to its molecular structure containing cyano (-CN), fluorine atom (-F) and trifluoromethyl (-CF) and other functional groups, under specific conditions, such as high temperature, strong acid, and strong alkali environment, chemical reactions may occur, resulting in structural changes, affecting its performance and use.
3-Cyano-4-Fluorobenzotrifluoride~ Alpha, Alpha, Alpha, 6-Tetrafluoro-M-Tolunitrile are chemically stable?
3-Cyano-4-fluorotrifluorotoluene (3-Cyano-4-Fluorobenzotrifluoride) is also known as α, α, α, 6-tetrafluoro-m-toluonitrile (Alpha, α, α, 6-Tetrafluoro-M-Tolunitrile). The chemical properties of this substance are quite stable.
Looking at its structure, the cyano group (-CN) is connected to the benzene ring, and the fluorine atom (F) and trifluoromethyl (-CF) are also on the benzene ring. The carbon-nitrogen triple bond in the cyanide group is quite stable, giving the substance a certain chemical stability. Fluorine atoms can change the distribution of molecular electron clouds and strengthen molecular stability due to their strong electronegativity. Trifluoromethyl has strong electron absorption, which further affects the electron cloud density of the benzene ring, reducing the overall chemical activity of the molecule and enhancing the stability.
In terms of reactivity, due to the influence of the above groups, common reactions such as nucleophilic substitution and electrophilic substitution require specific conditions to occur. For example, nucleophilic substitution reactions require strong nucleophilic reagents and appropriate temperature, catalyst and other conditions. Because of its structure, the electron cloud density at the check point of the reaction is not conducive to the attack of nucleophilic reagents.
In common organic solvents, the substance has good solubility. This property is conducive to the reaction being carried out in a homogeneous system when it participates in organic synthesis reactions, ensuring a smooth and orderly reaction, and thus ensuring the relative stability of its chemical properties during the reaction process.
In addition, under general environmental conditions, the substance has a certain tolerance to external factors such as heat and light. Moderate heating, without special reagents or conditions, its structure and chemical properties are not easily changed; under ordinary light, it can also remain stable, and it is not easy to occur photolysis and other reactions.
In summary, 3-cyano-4-fluorotrifluorotoluene (α,α,α, 6-tetrafluoro-m-toluonitrile) is relatively stable in chemical properties.
3-Cyano-4-Fluorobenzotrifluoride~ Alpha, Alpha, Alpha, what is the production method of 6-Tetrafluoro-M-Tolunitrile
3-Cyano-4-fluorotrifluorotoluene (3-Cyano-4-Fluorobenzotrifluoride), also known as α, α, α, 6-tetrafluoro-m-toluonitrile (Alpha, α, α, 6-Tetrafluoro-M-Tolunitrile), is prepared by the following methods.
First, fluoroaromatic hydrocarbons are used as starting materials. Under specific conditions, fluoroaromatic hydrocarbons are first combined with suitable nucleophiles, such as cyanide reagents, through nucleophilic substitution reaction to introduce cyano groups. In this reaction, the reaction temperature, reaction time and the ratio of reactants are all key factors. If the temperature is too high, it is feared that side reactions will occur; if the temperature is too low, the reaction rate will be slow. If the reaction time is too short, it is difficult to fully convert the raw materials; if the time is too long, it will only increase energy consumption and cost. Improper ratio of reactants will also affect the yield and purity of the product.
Second, through the cyanidation path of halogenated aromatics. First halogenate aromatics to obtain halogenated aromatics, and then cyanide the halogenated aromatics and cyanide agents under the action of the catalyst. The type and amount of catalyst selected have a great impact on the reaction. Excellent catalysts can significantly improve the reaction activity and selectivity. And the solvent of the reaction system also needs to be carefully selected. Different solvents have different effects on the reaction rate and product distribution.
Third, through the strategy of functional group transformation. Take aromatic derivatives containing other convertible functional groups as the starting material, first modify them with specific functional groups, and gradually build the structure of the target molecule. Finally, through appropriate reactions, the relevant functional groups are converted into cyano and fluorine substituents. This process requires precise control of the conditions of each step of the reaction to ensure that the reaction proceeds according to the predetermined path to achieve higher yield and purity.
All kinds of preparation methods have advantages and disadvantages. In actual production, it is necessary to comprehensively consider the availability of raw materials, cost, difficulty in controlling reaction conditions, and quality requirements of products, and choose the most suitable one to achieve the purpose of efficient preparation of 3-cyano-4-fluorotrifluorotoluene.
3-Cyano-4-Fluorobenzotrifluoride~ What is the price range of Alpha, Alpha, Alpha, 6-Tetrafluoro-M-Tolunitrile in the market?
3-Cyano-4-fluorotrifluorotoluene (3-Cyano-4-Fluorobenzotrifluoride), also known as α, α, α, 6-tetrafluoro-m-toluonitrile (Alpha, α, α, 6-Tetrafluoro-M-Tolunitrile), is a key intermediate in the field of organic synthesis and is widely used in medicine, pesticides and materials industries. However, its market price range is difficult to determine exactly, because many factors will affect it.
The first one is the market supply and demand relationship. If the market demand for 3-cyano-4-fluorotrifluorotoluene is strong, and the supply is relatively short, the price will rise; conversely, if the demand is weak and the supply is excessive, the price will inevitably fall. For example, when the pharmaceutical industry develops a new best-selling drug with it as a key intermediate, the demand for it may increase sharply, which will then drive up the price.
Furthermore, production costs are also an important factor. The cost of raw materials, the complexity of the production process, and energy consumption will all affect the final price. If the price of raw materials fluctuates frequently, or the production process needs to be expensive to maintain, the price of the product will change accordingly. For example, if the price of key raw materials required for production rises due to resource scarcity or other reasons, the production cost of 3-cyano-4-fluorotrifluorotoluene will increase accordingly.
In addition, the market competition situation should not be underestimated. If there are many companies producing this product in the market and the competition is fierce, the company may adopt a price reduction strategy in order to seize market share; if the market is in a monopoly or oligopoly state, the price may be controlled by the company.
Under normal circumstances, the price of 3-cyano-4-fluorotrifluorotoluene may range from tens of yuan to hundreds of yuan per kilogram. However, this is only a rough range, and the actual price also needs to refer to the specific purchase volume, transaction time, product purity and other factors. If the purchase volume is large, or the preferential price can be negotiated with the supplier; the higher the product purity requirements, the higher the price may be.
To know the exact market price, the buyer should contact the relevant suppliers and compare the prices from multiple parties to obtain the most accurate price information that meets their own needs.
