To sum up, M-diethylbenzene is of great value in many fields such as chemical industry, rubber, medicine, pesticide, etc. It is widely used and plays a key role in promoting the development of related industries.

What are the physical properties of M-diethylbenzene?

M-diethylbenzene is also an organic compound. Its physical properties are quite specific, and I will describe them in detail for you today.

Looking at its shape, under room temperature and pressure, M-diethylbenzene is a colorless and transparent liquid with a pure and clear texture. It can be seen as clear water, but it has a unique quality. Its smell is fragrant, but this fragrance is not pleasant, but it has a certain degree of irritation, and it is easy to feel uncomfortable when smelled.

As for the boiling point, it is between 181 ° C and 184 ° C. This temperature range is the key limit for its transformation from liquid to gas. At this temperature, the thermal motion of the molecule intensifies enough to break free from the shackles of the liquid phase and turn into curling steam. The melting point is about -87.9 ° C. When the temperature drops, the molecular activity slows down and gradually arranges in a regular manner, and then solidifies from the flowing liquid.

M-diethylbenzene has a lighter density, about 0.86 g/cm ³, which is lighter than water. If the two are mixed, it will float on the water, like oil floating in water, with a clear boundary. And it is difficult to dissolve in water, the two meet, such as ice and charcoal, and repel each other. However, in organic solvents, such as ethanol and ether, M-diethylbenzene can dissolve with it, just like water emulsion, showing good solubility.

In addition, M-diethylbenzene is flammable, and it is very easy to burn in case of open flames and hot topics. It can start a raging fire instantly, and it will produce black smoke when burning. Because of its high carbon content, it is impossible to burn. Therefore, when storing and using, be careful to keep away from fire sources and hot topic environments to prevent unexpected disasters.

Is the chemical property of M-diethylbenzene stable?

The chemical properties of M-diethylbenzene are quite stable under normal temperature and pressure. The cover contains benzene rings because of its molecular structure, which has the commonality of aromatic hydrocarbons. The conjugated system of benzene rings makes its electron cloud evenly distributed and increases its stability.

Under specific conditions, it can also be active. In case of high temperature and open flame, it can burn violently, generating a lot of heat and carbon dioxide, water and other products. This is because it is rich in hydrocarbons and flammable.

With the assistance of catalysts, it can participate in many reactions. For example, with halogens, catalyzed by Lewis acid, a substitution reaction can occur, and halogen atoms replace hydrogen atoms on the benzene ring. It can also co-heat with concentrated sulfuric acid and concentrated nitric acid, perform nitrification reaction, and introduce nitro group to benzene ring.

And the ethyl group of the side chain is affected by the benzene ring and has unique activity. It can be oxidized. In case of strong oxidants, such as acidic potassium permanganate solution, ethyl group can be gradually oxidized to carboxyl group.

Overall, M-diethylbenzene is stable in general environment, but under specific chemical conditions, it can exhibit various chemical activities and participate in various organic reactions. It is an important raw material for organic synthesis.

What is the production process of M-diethylbenzene?

M-diethylbenzene is an important product in the chemical industry. Its manufacturing process is different from the ancient method and the current method, and the steps are complicated and interlocking, so there is no room for sloppiness.

In the past, benzene and ethylene were mostly used as the starting materials. First, benzene is placed in various special reactors. The kettle is the most important place for chemical reactions. It is made of excellent materials and can withstand high temperature and high pressure. Then ethylene is added, and a catalyst is added. The catalyst, if the guide of the chemical reaction, can promote the reaction to go quickly. This reaction needs to be controlled at a suitable temperature. If the temperature is too high, side reactions will be plentiful, and if it is too low, the reaction will be slow. When the temperature stabilizes at a certain range, benzene and ethylene then react with alkylation to produce ethylbenzene. This ethylbenzene is complex with ethylene, and under specific conditions, it is alkylated again, and finally M-diethylbenzene is obtained. However, this method has many impurities, is difficult to purify, takes a long time and is expensive.

Today's process is more refined. Zeolite is often used as a catalyst, and zeolite has a unique pore structure and good selectivity. Benzene and ethylene are used as raw materials to react in a fixed bed reactor. In a fixed bed, the flow of the material is stable and the reaction is easy to control. During the reaction, the temperature, pressure and flow rate of the material are precisely adjusted. The temperature is fine-tuned according to the reaction process, and the pressure is also changed in a timely manner. The flow rate of the material depends on the rate of the reaction and the purity of the product. After this reaction, the proportion of M-diethylbenzene in the product is quite high, and there are few impurities. The post-processing is convenient, the energy consumption is also low, and the cost is reduced, which is important for today's industrial production.

What is the price range of M-diethylbenzene in the market?

M-diethylbenzene is in the market, and its price is quite difficult to determine. In this case, due to the complex market conditions, the price fluctuation is changeable, and various factors can cause it to change.

First, the price of raw materials has a huge impact on the pricing of M-diethylbenzene. If the price of raw materials increases, the cost of making this product will increase, and the price will also rise; on the contrary, the price of raw materials will decrease, the cost will decrease, and the price may appear to be falling.

Second, the trend of supply and demand is also the key. There are many people in the market who want M-diethylbenzene, and the supply is small, the price will rise; if the supply exceeds the demand, the stock will be difficult to sell, and the price will be lower for promotion.

Third, the difference between processes is also related to price. Advanced processes may reduce costs and improve quality, and the price may be excellent; while the old process, the cost is high, the quality is poor, and the price may be high.

Fourth, in the field of the market, the price is also different. In prosperous places, the demand is large, and the price may be high; in remote places, the demand is small, and the price may be low.

Overall, the market price of M-diethylbenzene is roughly between [X1] yuan and [X2] yuan per ton. However, this is only an approximation, and the actual price should be determined by real-time market conditions, supply and demand, costs and other factors, and cannot be generalized.
