What are the physical properties of 1-bromo-3-fluoro-2- (trifluoromethyl) benzene?
1 + - - 3 + - - - 2- (triethylmethyl) germanium, its physical properties are as follows:
The color state of this substance is often a colorless and transparent liquid at room temperature. Viewed like water, its quality is clear, and no impurities are visible. Its smell, slightly specific aromatic aroma, although not pungent and unpleasant, it also has a unique taste. If you smell it carefully, you can feel that it is different from common odorless liquids.
When it comes to density, it is slightly lighter than water. If it is co-placed with water, it can be seen that it floats on water, and the two are distinct. Its melting point is quite low, and it has already been in a liquid state under normal temperature. If it wants to solidify, it needs to be reduced to a very low temperature. The boiling point is relatively moderate, and when heated to this temperature, it will turn into a gaseous state.
Furthermore, its solubility also has characteristics. In organic solvents, such as ethanol, ether, etc., they can be well miscible, just like water emulsifying and fusing into one; however, in water, it is extremely difficult to dissolve, and the two meet, such as oil and water, which are separated by themselves.
Its conductivity is very weak, almost non-existent, and it is difficult to conduct current when placed in a circuit, just like a barrier that blocks current. Thermal conductivity is also average, and the heat transfer effect is not significant. When heated, the speed of heating up and heat dissipation is not rapid.
In addition, the substance is volatile to a certain extent. In an open vessel, its amount gradually decreases after a little time, due to the fact that its molecules are dissipated in the air.
What are the chemical properties of 1-bromo-3-fluoro-2- (trifluoromethyl) benzene?
The chemical properties of Fu 1 + -3 + -Jiang-2- (triethyl) benzene can be studied. This compound contains a specific atomic combination and structure, with different structures and properties.
Looking at its structure, the benzene ring is its basic structure and has aromatic properties. The electron cloud distribution of the benzene ring is special, which gives it stability. It is difficult to perform addition reactions, and most of them are electrophilic substitution reactions. Its π electronic system can interact with electrophilic reagents and introduce foreign groups to replace the hydrogen atoms on the benzene ring.
Furthermore, although the alkyl part connected is slightly less active than the benzene ring, it also affects the overall properties. Alkyl groups have a donor electron induction effect, which can slightly increase the electron cloud density of the benzene ring. During the electrophilic substitution reaction, the reaction is more likely to occur, and the position of the substituent entering the benzene ring is affected. Generally speaking, alkyl groups are ortho-and para-localization groups, and electrophilic reagents tend to attack the ortho-and para-position of the benzene ring more.
In terms of physical properties, due to the existence of van der Waals forces between molecules, the melting point is related to the relative molecular mass and the intermolecular force. Containing alkyl groups increases the polarity of the molecules slightly, but the whole is still a non-polar or weakly polar compound, so it has good solubility in organic solvents and poor solubility in water.
In terms of chemical activity, in addition to electrophilic substitution, if a strong oxidant is encountered, the alkyl group may be oxidized, and when the conditions are appropriate, the benzene ring may also be oxidized. However, due to the high stability of the benzene ring, the oxidation reaction requires specific conditions and strong oxidants to proceed.
In summary, 1 + -3 + -Jiang-2- (triethyl) benzene has a unique structure, aromaticity, specific reactivity and physical properties, which is very important for research and application in the field of organic chemistry.
What is the production method of 1-bromo-3-fluoro-2- (trifluoromethyl) benzene?
The method of 1 + -3 + -hydrocarbon-2- (Sanjiang methyl) ether is as follows:
First take the amount of hydrocarbon powder, soak it in water, and let it melt. After it is placed in the ground, place it in a kettle and cook it slowly over low heat, without burning, so that the water is homogenized until it is a paste, this is the first step.
Take another water from Sanjiang, and it is necessary to take the water from the upstream to clear the dye, and remove the sand, angstroms, etc., for use.
In the powder of the above paste, pour it into the well-treated river water, and keep mixing with the water to make the two fully blend. Boil the mixture over a slow fire to maintain an appropriate temperature, and the mixture can be produced one by one.
Next, add the amount of methylation. The amount of methylation needs to be measured carefully to ensure the quality of the reaction. The addition of water also needs to be slow, and the amount of water needs to be added to make the reaction even.
During the reaction process, closely observe the color, soil, etc. of the mixture. When the reaction reaches the stage of the reaction, stop the fire and let it cool. Cold, the product can be formed, and the appropriate equipment can be used to remove the excess moisture and the amount of water that has not been reversed. The most suitable can be obtained is 1 + - 3 + - - - - 2- (Sanjiang methyl) ether.
Throughout the process, it is necessary to pay attention to the control of the heat, the dosage of the fuel, and the operation of each step. If there is a slight error, it may affect the quality of the product.
Precautions for storage and transportation of 1-bromo-3-fluoro-2-trifluoromethyl benzene
1 + - 3 + - Jiang-2 - (Sanjiang methyl) ether is in the storage environment, and there are many things to be paid attention to.
The first thing to do is to dry up in the environment. This ether is prone to change in contact with water, so it can avoid the dryness of the atmosphere, and it can be generated by the shadow of the environment. Furthermore, it is necessary to pay attention to the degree. It should be stored in the environment, because of its nature or high shadow. If the degree is high, it may cause the reaction, cause the composition to change, and even risk safety.
And the container that is not stored also needs to be careful. It is advisable to use corrosion-resistant materials. This ether or some materials will react, causing the container to be damaged and affecting its products.
If it is damaged, the package will be damaged. To ensure that there is no leakage during the moving and bumpy journey. Once it is leaked, it is more likely to cause pollution to the surrounding environment. If it is exposed to people, it may also endanger personal health.
It is also necessary to know the characteristics of this ether. Know how to deal with it in the event of an accident, such as emergency measures for leakage, treatment methods for eyes if accidentally exposed, etc. Only in this way can we ensure the safety and stability of the 1 + - 3 + -Jiang-2 - (Sanjiang methyl) ether and avoid the occurrence of undesirable effects during the process of storage.
