What are the physical properties of M-Diethylbenzene?
M-diethylbenzene is one of the organic compounds. Its physical properties are unique.
Looking at its properties, under room temperature and pressure, it is mostly a colorless and transparent liquid, and emits an aromatic odor. This smell is similar to many aromatic hydrocarbons and is easily sensed by the sense of smell.
When it comes to boiling point, it is about 181 to 184 degrees Celsius. The value of boiling point is closely related to the intermolecular force. The van der Waals force between diethylbenzene molecules makes it need such a temperature to change from liquid to gaseous.
The melting point is roughly around -48 degrees Celsius. The characteristics of the melting point reflect the temperature limit of the transition between the solid and liquid states of the substance, indicating that below this temperature, M-diethylbenzene will exist in solid form.
Its density is about 0.86 grams per cubic centimeter, which is slightly smaller than that of water. Therefore, if mixed with water, it will float on the water surface.
In terms of solubility, M-diethylbenzene is insoluble in water, but can be miscible with most organic solvents, such as ethanol, ether, acetone, etc., in any ratio. This is due to the principle of "similarity and miscibility", its molecular structure is similar to that of organic solvents, so it can be miscible with each other.
In addition, the vapor density of M-diethylbenzene is greater than that of air. If it leaks in the air, the steam is easy to spread at a lower place, which poses a certain safety hazard. Its volatility is moderate, and under certain conditions, it can dissipate into the air, which in turn affects the surrounding environment.
What are the chemical properties of M-Diethylbenzene?
M-Diethylbenzene (M-Diethylbenzene), like a colorless and transparent liquid, has a fragrant smell. Its melting degree is about -83 ° C, its boiling point is nearly 181 ° C, its density is lighter than that of water, and it can float in the air.
This substance has certain volatile properties, and can slowly dissipate into the air at room temperature. It is flammable, and it is easy to burn when exposed to open flames and hot topics. When burned, the flame is bright and accompanied by thick smoke.
The chemical activity of m-diethylbenzene is reflected in its ability to react with many chemical reagents. In case of strong oxidants, violent oxidation reactions can occur, and even the risk of explosion may occur. In its molecular structure, the stability of the benzene ring allows it to undergo substitution reactions, and the presence of ethyl groups endows it with unique chemical properties. Under appropriate conditions, ethyl can be replaced by other groups to form different compounds.
In terms of solubility, m-diethylbenzene is insoluble in water, but it can be miscible with most organic solvents, such as ethanol, ether, etc. This property makes it useful in the field of organic synthesis. It is often used as a solvent to assist in many chemical reactions.
However, it should be noted that m-diethylbenzene has certain hazards to the human body. Its vapor can irritate the eyes and respiratory mucosa. If people inhale too much, it can cause dizziness, headache, nausea and other discomforts. Long-term exposure may damage the nervous system and hematopoietic system. Therefore, when using and storing m-diethylbenzene, it is necessary to follow strict safety procedures and take protective measures.
What are the production methods of M-Diethylbenzene?
M-diethylbenzene is a common raw material in the chemical industry. The preparation method can be followed in many ways, as follows:
First, the alkylation method. This is a classic method, using benzene and ethylene as materials, under the action of a catalyst, the alkylation reaction is carried out. The common catalysts used are aluminum trichloride, hydrofluoric acid, etc. Under suitable temperature and pressure, benzene and ethylene are combined to obtain a mixture of diethylbenzene, which contains M-diethylbenzene. In this process, the activity and selectivity of the catalyst have a great influence on the composition of the product. If you want to increase the yield of M-diethylbenzene, you need to fine-tune the reaction conditions, such as temperature, pressure, and the ratio of raw materials.
Second, the isomerization method. Take other ethylbenzene isomers as the starting materials, and convert them into M-diethylbenzene through the isomerization reaction. This reaction usually needs to be carried out under specific catalysts and reaction conditions. The catalysts, such as zeolite catalysts, have the characteristics of shape-selective catalysis, which can effectively guide the direction of isomerization and increase the output of M-diethylbenzene. The temperature and time of the reaction also need to be precisely controlled to achieve the desired effect.
Third, the separation method. In the process of petrochemical industry, such as reforming to form oil, cracking gasoline and other mixtures, which contain various isomers of diethylbenzene. M-diethylbenzene can be extracted from the mixture by means of physical separation, such as distillation, adsorption separation, etc. The method of distillation is based on the different boiling points of each component, and it is gasified and condensed many times to achieve the purpose of separation; adsorption separation is based on the different adsorption capacity of the adsorbent to different isomers to achieve the enrichment and separation of M-diethylbenzene. These methods have their own advantages and disadvantages. In actual production, according to the conditions of the raw materials, the requirements of the product and other factors, a suitable method or a combination of numbers are often selected to achieve the goal of efficient preparation of M-diethylbenzene.
What to pay attention to when storing and transporting M-Diethylbenzene
M-diethylbenzene is an organic compound. When storing and transporting it, it is necessary to pay attention to many matters.
When storing, the first choice of environment. When placed in a cool and ventilated warehouse, away from fire and heat sources. This is because diethylbenzene is flammable, and it is dangerous to cause combustion and explosion in case of open flame and high heat energy. The temperature of the warehouse should be strictly controlled, generally not more than 37 ° C, in order to prevent its volatilization from being intensified due to excessive temperature and increase the risk factor.
Furthermore, storage containers are also crucial. A sealed container must be used to prevent its volatilization and escape, pollute the environment, and avoid the formation of explosive mixtures with air. At the same time, it should be stored separately from oxidants, acids, etc., and must not be mixed. Due to the contact of diethylbenzene with oxidants, severe oxidation reactions are prone to occur, causing danger; coexistence with acid substances may cause chemical reactions and affect its stability.
When transporting, it is necessary to strictly abide by relevant regulations. Transportation vehicles must be equipped with corresponding varieties and quantities of fire equipment and leakage emergency treatment equipment. During driving, drivers should drive cautiously and avoid intense operations such as sudden braking and sharp turns to prevent damage to containers and leakage of diethylbenzene. During transportation, it is also necessary to prevent exposure to the sun, rain, and stay away from high temperature areas.
If it is road transportation, drive according to the specified route, and do not stop in residential areas and densely populated areas. During railway transportation, make sure that the container is stable and prevent displacement and collision during transportation. All these are to ensure the safety of M-diethylbenzene storage and transportation, and must not be slack and negligent.
