What are the physical properties of M-iodo-alpha, alpha, alpha-trifluorotoluene
M- -α,α,α - trifluorotoluene, which is an organic compound. It has the following physical properties:
Under normal conditions, it is a colorless to light yellow liquid with a clear appearance and good visibility. It is like a clear spring and refracts a fascinating luster under light.
Smell it, it has a special smell, although it is difficult to describe accurately, it can be clearly sensed in the air, just like in a quiet garden, and it can be distinguished from its unique fragrance.
As for the boiling point, it is about 170-172 ° C. Just like water will boil and change its form at 100 ° C. In this temperature range, the molecular motion of this compound intensifies and changes from liquid to gaseous state. The melting point of
is about -38 ° C. When the ambient temperature drops to this point, the molecular activity weakens and gradually solidifies from the flowing liquid state, as if time is still.
In terms of density, it is about 1.86 g/cm ³, which is heavier than water. If mixed with water, it will settle in the lower layer of water like a stone sinking to the bottom.
In terms of solubility, it is slightly soluble in water, but easily soluble in organic solvents, such as ethanol, ether, etc. Just like fish entering water, it can freely "shuttle" in organic solvents. This is due to the principle of similar miscibility, and its molecular structure is more compatible with organic solvents.
Its vapor pressure is low, which means that at room temperature, the tendency to volatilize into the air is relatively small, and the ability of molecules to escape from the liquid surface is limited, which is relatively stable in the air.
The refractive index is about 1.468-1.470. When light passes through, it will be refracted like a prism. This value can help to identify the compound, just like a human fingerprint, for its unique identification.
In summary, the physical properties of M-iodide -α,α,α - trifluorotoluene make it shine in many fields such as organic synthesis, such as shining stars, and is used for chemical research and industrial production.
What is the synthesis method of M-iodo-alpha, alpha, alpha-trifluorotoluene
The method for preparing m-iodo-alpha, alpha, alpha-trifluorotoluene is often followed as follows.
First, m-aminotrifluorotoluene is used as the starting material. First, it is diazotized with sodium nitrite and hydrochloric acid at low temperature. This process requires fine temperature control to prevent side reactions from breeding. After the diazotization product is formed, it is reacted with potassium iodide to obtain m-iotrifluorotoluene. The advantage of this route is that the starting material is relatively easy to obtain and the reaction step is clear. However, the diazotization reaction operation needs to be rigorous. Due to the poor stability of diazonium salts, it is easy to cause danger if it is not careful.
Second, it can be started from m-trifluoromethylbenzoic acid. The acid chloride is first converted into an acyl chloride, and thionyl chloride is often used to interact with it. The reaction conditions are mild and the yield is considerable. The acyl chloride is then reacted with potassium iodide under the catalysis of copper salts through the Sandmeier reaction to achieve the conversion of carboxyl groups to iodine atoms, thereby obtaining the target product. This path avoids the high risk of diazotization reaction, but the multi-step reaction leads to the growth of the overall process. It is necessary to pay attention to the purification of each step of the reaction to ensure the purity of the final product.
Or start with m-bromotrifluorotoluene and pass the halogen exchange reaction catalyzed by palladium. In the presence of suitable ligands and bases, it reacts with iodizing reagents such as cuprous iodide, so that the This method has good selectivity and can effectively reduce the generation of by-products, but the price of palladium catalysts is high, which increases the production cost.
All synthetic methods have their own advantages and disadvantages. In practical application, it is necessary to comprehensively weigh factors such as raw material availability, cost considerations, and product purity requirements, and choose the best one.
M-iodo-alpha, alpha, alpha-trifluorotoluene what to pay attention to when storing
M-iodo - α,α,α - trifluorotoluene is an organic compound containing iodine and fluorine. When storing, the following numbers should be paid attention to:
First, this substance has a certain volatility, so it should be stored in a sealed container to prevent it from escaping into the air. The sealed device can avoid its volatilization loss and reduce its impact on the surrounding environment.
Second, because of its halogen-containing atoms, it is more active. It should be kept away from fire sources and hot topics to prevent the risk of combustion or explosion. Hot topics can cause their chemical bonds to break and stimulate chemical reactions, and fire places are more likely to involve them in combustion reactions, causing danger to breed.
Third, in view of the organic halide or harmful to the human body, the storage place should be well ventilated. In this way, if there is a small amount of volatilization, it can be dispersed in the atmosphere in time to reduce its concentration in local space and protect the health of the depositor.
Fourth, such compounds may react with other substances, so they should not be co-stored with reagents with strong activity. Such as strong oxidants and strong bases, etc., should be placed separately from them to avoid interaction and unpredictable reactions.
Fifth, the storage temperature should be moderate, not too high or too low. If the temperature is too high, it will increase its reactivity and volatilization rate; if the temperature is too low, it may cause it to solidify, which will affect the use, and some container materials may become brittle at low temperatures, increasing the risk of leakage.
In short, the storage of M-iodo - α,α,α - trifluorotoluene requires caution. According to its physical and chemical properties, efforts should be made in terms of sealing, fire protection, ventilation, isolation and temperature control to ensure the safety of storage.
