What are the physical properties of M-Hydroxybenzotrifluoride?
M-hydroxytrifluorotoluene is an important compound in organic chemistry. It has the following physical properties:
Viewed, it is often a colorless to light yellow transparent liquid, with a little luster visible in sunlight, like morning light sprinkling on the clear liquid, clear and slightly pan-colored.
Smell it, it has a specific smell, although it is not pungent and intolerable, it has unique characteristics, such as being in a specific chemical atmosphere, the smell is unique.
When it comes to the melting boiling point, the melting point is about -27 ° C, just like the temperature of a cold night. Below this temperature, the liquid will gradually condense into a solid state, as if time freezes, and the shape changes; the boiling point is about 189-191 ° C. When the temperature rises to this point, it is like a phoenix nirvana, rising from the liquefied gas.
Its density is about 1.376g/cm ³, which is heavier than water. If it is placed in one place with water, it will be like a stone sinking to the bottom of the water and slowly settling.
In terms of solubility, it can be well miscible in organic solvents such as ethanol and ether, just like fish entering water, and the phase is inseparable; however, the solubility in water is very small, and the two seem to repel each other, and they are distinct.
Vapor pressure has a certain value under specific conditions, reflecting its volatilization difficulty, just like the vitality of molecules, some molecules break free and escape into the gas phase.
These physical properties are the characteristics of M-hydroxytrifluorotoluene, which is of great significance in many fields such as organic synthesis and chemical production, laying the foundation for related research and applications.
Is M-Hydroxybenzotrifluoride chemically stable?
M-Hydroxybenzotrifluoride, that is, m-hydroxytrifluorotoluene, has quite stable chemical properties.
In the molecular structure of m-hydroxytrifluorotoluene, the benzene ring is relatively stable, and the π electrons on the benzene ring form a conjugated system, which endows the molecule with certain stability. Although the hydroxyl group (-OH) has a certain activity, its activity is changed by the electron effect of the benzene ring after being connected to the benzene ring. The fluorine atom (F) has strong electronegativity, which makes the trifluoromethyl (-CF) have strong electron absorption, which further stabilizes the molecule.
From the perspective of reactivity, when m-hydroxytrifluorotoluene participates in the electrophilic substitution reaction, the hydroxyl group is an ortho-and para-site locator, which can increase the electron cloud density of the benzene ring ortho-and para-site relatively, which is conducive to the attack of electrophilic reagents. However, the strong electron absorption of trifluoromethyl will weaken the electron cloud density of the benzene ring and reduce the reactivity to a certain extent. The interaction of these two groups checks and balances each other, so that the reaction can be carried out efficiently under specific conditions.
In terms of redox, it is not easy to be oxidized or reduced under ordinary conditions. Because there are no functional groups in its structure that are easily acted by common oxidizing agents or reducing agents. Only when strong oxidation or strong reduction conditions are matched with specific catalysts, the corresponding oxidation
In terms of thermal stability, due to the presence of benzene ring and trifluoromethyl, the compound has a hot topic stability. Within a certain temperature range, its structure and chemical properties remain stable, and reactions such as decomposition or rearrangement may occur at high temperatures, but the required temperature is higher.
From the storage point of view, because of its stable chemical properties, it can be stored for a long time without deterioration at room temperature, dry and dark environment. Just pay attention to avoid contact with strong oxidants, strong acids, strong bases and other substances to prevent chemical reactions.
What is the production process of M-Hydroxybenzotrifluoride?
M-hydroxytrifluorotoluene, the method of preparation, is quite complicated. The process starts with m-hydroxybenzoic acid, and after multiple steps of delicate changes, this product is obtained.
At the beginning, m-hydroxybenzoic acid and thionyl chloride are co-located at an appropriate temperature to make them combine. In this step, the acid and thionyl chloride react, and the carboxyl group then converts into the shape of an acid chloride. This acid chloride is very active, paving the way for the next step.
Then, the acid chloride coresponds with hydrogen fluoride. The power of hydrogen fluoride makes the structure of the acid chloride change, and the fluorine atom ingeniously enters it, replacing the other group in the original, and gradually forms the shape of trifluoromethyl. The point of this step is that when controlling the temperature and responding, do not make the reaction pass and cause impurities to grow.
After the step, it is reduced by the method. With a suitable reducing agent, some of the products obtained in the previous step are radicalized, and finally the shape of M-hydroxytrifluorotoluene is formed. The reducing agent must be selected carefully and the amount must be accurate to ensure the purity of the product.
Each step should be carefully observed. Temperature, pressure and time are all important. After the application, the purification process, such as distillation and crystallization, removes its impurities and improves its purity, so as to obtain a fine M-hydroxytrifluorotoluene for the needs of all parties.
What is the price range of M-Hydroxybenzotrifluoride in the market?
M - Hydroxybenzotrifluoride, chemical materials are also. It is difficult to determine the price range in the market. The price of the product is influenced by many factors, such as the state of market supply and demand, changes in raw material costs, the simplicity of production processes, and the situation of industry competition.
In the past, if there were many seekers in the market and few suppliers, the price would rise; if the price of raw materials was high, the production cost would increase greatly, and the sales would also be high. And in different regions, due to differences in logistics costs and tax policies, the price would also vary.
And the improvement of production technology may lead to an increase in output, a decrease in cost, and a decrease in price. Where the competition in the industry is fierce, the merchants will sell their goods, or reduce their prices to compete for the market.
If based on past market conditions, the price may vary from time to time and fluctuate. Sometimes the price per kilogram may be in the tens of yuan, or due to special circumstances, it may rise to more than 100 yuan, or due to special supply and demand conditions, the price may be as high as hundreds of yuan per kilogram. However, this is a rough estimate. If you want to know the exact price, you still need to carefully observe the current market conditions, ask relevant merchants, dealers, or refer to professional market reports to obtain the near-real price.
