What are the physical properties of 2,4,5-trifluorotoluene?

2% 2C4% 2C5-tribromotoluene is also an organic compound. Its physical properties are quite unique, let me tell you one by one.

Looking at its morphology, under room temperature and pressure, 2% 2C4% 2C5-tribromotoluene is mostly white to light yellow crystalline powder with fine texture and can be identified. It has a certain melting point, about 104 ° C - 107 ° C. In this temperature range, the substance gradually melts from solid to liquid, and this phase transition process is quite orderly.

As for the boiling point, it is about 314 ° C - 316 ° C. When the temperature rises, the liquid 2% 2C4% 2C5-tribromotoluene will be converted into a gaseous state and dissipate in space.

In terms of solubility, 2% 2C4% 2C5-tribromotoluene is insoluble in water. Because the polarity of water molecules is contrary to the non-polar structure of the compound, the two repel each other, so it is difficult to blend. However, it is soluble in many organic solvents, such as benzene, toluene, chloroform, etc. Due to the principle of "similarity and miscibility", the non-polar properties of organic solvents are similar to 2% 2C4% 2C5-tribromotoluene, so they are miscible.

In terms of density, 2% 2C4% 2C5-tribromotoluene is heavier than water, about 2.25 g/cm ³. If it is placed in water, it will sink to the bottom.

In addition, 2% 2C4% 2C5-tribromotoluene is relatively stable under normal conditions. In case of extreme conditions such as hot topics, open flames, or contact with strong oxidants, it may also cause dangerous reactions, which cannot be ignored. Although its smell is not strong, it still has certain particularity, and it can be sensed by smelling. This is the physical properties of 2% 2C4% 2C5-tribromotoluene.

Is the chemical properties of 2,4,5-trifluorotoluene stable?

The chemical properties of 2% 2C4% 2C5-tribromotoluene are quite stable at ordinary times. In this compound, the bromine atom is connected to the benzene ring, and the conjugation system of the benzene ring gives it a certain stability.

Although the bromine atom has a certain electronegativity, the conjugation of it with the benzene ring makes the electron cloud distribution more uniform and weakens its reactivity. Under normal mild conditions, such as room temperature and pressure, and without the action of special reagents, 2% 2C4% 2C5-tribromotoluene is not prone to significant chemical reactions.

However, when it encounters strong oxidants, such as the mixed acid of concentrated nitric acid and concentrated sulfuric acid, or under extreme conditions such as high temperature and light, its stability will also be affected. At this time, the hydrogen atom on the benzene ring may be replaced, and the bromine atom may also participate in the reaction, causing its structure and properties to change.

But in general, if there is no external strong factor interference, 2% 2C4% 2C5-tribromotoluene can maintain a relatively stable chemical state, and it is not easy to undergo violent chemical changes on its own. In common storage and general use environments, its properties can remain relatively stable.

What are the preparation methods of 2,4,5-trifluorotoluene?

The preparation method of 2% 2C4% 2C5-tribromotoluene is very different. The ancient family wanted to make this substance, and often went through various ways.

One method is to use toluene as the base, so that it can be used with bromine in a specific environment. First put toluene in the kettle, add an appropriate amount of catalyst, such as iron filings or its halide. For bromine, when it is dripped slowly, and its temperature is controlled, it will not be too high to avoid side reactions. In this process, bromine and toluene should be substituted to gradually produce 2% 2C4% 2C5-tribromotoluene. After the process is completed, it is washed with water to remove the unwanted bromine and impurities, and then distilled to purify the pure product.

There is another method, first nitrifying toluene to obtain nitrotoluene. Nitro can lead bromine to a specific position in the benzene ring. Later, by reducing the method, the nitro group is removed to obtain the corresponding bromotoluene. Although this step is slightly complicated, it can increase the selectivity of the product, so that the yield of 2% 2C4% 2C5-tribromotoluene is better.

There are those who start with other compounds and convert them in multiple steps to produce them. For example, with an aromatic hydrocarbon derivative, first through the change of functional groups, introduce groups that can respond to bromine, and then through bromination, removal of other groups, etc., the final product is 2% 2C4% 2C5-tribromotoluene.

The preparation method has advantages and disadvantages. In the case of toluene directly responding to bromine, the steps are simple, but there are many side effects, and the yield is not high; by the method of nitrification and reduction, although the steps are increased, the product is pure and the yield is excellent. Fang family when needed, choose the method on balance.

What is the price range of 2,4,5-trifluorotoluene in the market?

The price of 2,4,5-trifluoroacetylbenzene varies according to the quality and quantity and the supply and demand of the market. Generally speaking, its price is in the range of tens to hundreds of gold per gram. If it is a high-purity product, and there are many people who want it, its price will be higher; if the quality is slightly inferior, or the supply is oversupplied, the price may be slightly reduced.

The sources of goods in the market vary. There are those refined by self-named factories, whose quality is high and the price is high; there are also those from small workshops, whose price is cheap, but the quality is high or difficult. If the buyer chooses this product, he must review its quality and choose its price before he can get it.

Looking at the state of the cities, the price of this material fluctuates, and it is not separated from supply, demand and quality. The industry adjusts its production and sales according to the changes in the market, and expects to make a big profit. And buyers should also choose the right one according to the situation. Although it is difficult to determine the exact number, it is about tens to hundreds of gold per gram, which can be used as a lesson for those who enter the market.
