What are the physical properties of α, α, α, 3-tetrafluorotoluene?

"Tiangong Kaiwu" said: "Where tetraallyl alcohol, its shape is like oil, its color is light yellow and clear, and its smell has a light fragrance. Its nature is mild, and the burning flame is bright and less smoky." Tetraallyl alcohol, with its unique physical properties, is valued by the world.

Its color is light yellow and clear, and it looks like amber is melting at the beginning, clear and transparent, like morning dew condensing in the stamens, its color is warm and moist but not flamboyant, giving people a soft feeling.

Its smell, with a light fragrance, leisurely like a spring breeze blowing through the flowers, the aroma is elegant, not pungent, not strong, just like the rain in the south of the Yangtze River, strands of smoke, refreshing, and refreshing to smell.

It burns, the flame is bright and less smoky. When it burns, the flame is as bright as day, like a bright star in the night sky, and the light is overflowing. And less smoke, no smoke and miasma disturbance, no pollution to the air, no fumigation of utensils, just like a gentleman's trip, bright and clean without foul marks.

As for the state of tetraallyl alcohol, it is oily at room temperature, the texture is delicate, the flow is silky smooth, and it feels warm when touched, just like jade fat in the hand, giving people a unique touch.

With these various physical properties, tetraallyl alcohol is useful in many fields, either as a fragrance supplement or as a choice for lighting. It is truly a wonderful thing in the world.

Is α, α, α, 3-tetrafluorotoluene chemically stable?

Titanium tetrachloride is not very stable. Titanium tetrachloride is a compound composed of titanium and chlorination.

Looking at the method of its preparation, it is mostly obtained by co-heating titanium ore with coke and chlorine gas. In this process, although various processes are used, the characteristics of titanium tetrachloride make it prone to changes in many situations.

Titanium tetrachloride is normally a colorless fuming liquid with a low boiling point, only about 136.4 ° C. In contact with water, it reacts rapidly, producing hydrochloric acid mist and titanium hydroxide. This violent reaction shows the activity of its chemical properties. If exposed to air, it is very easy to absorb water vapor and smoke, which is due to the reaction with water vapor in the air.

Furthermore, titanium tetrachloride is also unstable when heated. When it reaches a certain temperature, it can be decomposed into titanium and chlorine. Therefore, titanium tetrachloride should be carefully stored and transported to prevent accidents due to its active chemical properties. The cover cannot be said to be chemically stable because it is easy to interact with water, heat and other factors.

What are the preparation methods of α, α, α, 3-tetrafluorotoluene?

The method of making tetramethyl ether has been used in ancient times, and there are many methods, each of which is ingenious.

One is the method of co-heating ethanol and sulfuric acid. Take an appropriate amount of ethanol, place it in the kettle, slowly add sulfuric acid, and mix the two in an appropriate proportion. The sulfuric acid needs to be pure and the concentration is appropriate to be a good catalyst for the reaction. When heating, the temperature is particularly critical. When heating slowly over a low fire, the temperature in the kettle gradually rises to a suitable degree, about 140 degrees Celsius. At this time, the ethanol molecules are dehydrated and form tetramethyl ether. However, this process needs to be handled with caution, because sulfuric acid is highly corrosive, and if the reaction temperature is not properly controlled, side reactions will easily occur, resulting in impure products.

The second is the reaction of halogenated ethane with sodium alcohol. First take halogenated ethane, such as bromoethane, which has high halogen atom activity and is conducive to the reaction. Then prepare sodium alcohol, such as sodium ethanol, which is obtained by reacting alcohol with sodium metal. Put the two in a suitable solvent, such as anhydrous ether, which can promote the reaction without interfering with the main reaction. When the two meet, the halogen atom reacts with the alkoxy group of sodium alcohol, the halogen atom leaves, and the alkoxy group is connected to obtain tetramethyl ether. This reaction condition is relatively mild, but the preparation of halogenated ethane and sodium alcohol also requires fine operation, and the toxicity of halogenated ethane is not low, so be careful when using it.

The third is to use ethylene and water under the action of a catalyst to form ethanol first, and then make tetramethylether from ethanol. The ethylene gas is introduced into the aqueous solution containing a specific catalyst, such as phosphoric acid, etc., and the ethylene and water undergo an addition reaction to generate ethanol. When the ethanol is obtained, the follow-up operation is as described above by the method of making tetramethylether from ethanol. This route has a wide range of raw materials ethylene sources, but there are many reaction steps, which requires quite high requirements for reaction equipment and operation, and the choice and use of catalysts are related to the reaction efficiency and product purity, which requires careful consideration.

What should be paid attention to when storing and transporting α, α, α, 3-tetrafluorotoluene?

"Heavenly Works and Objects". In the matter of smelting, ask for caution from the warehouse, so as to ensure the quality of the utensils. For the storage of armor in C, C, C, 3-4, you need to pay special attention to the following points.

First, the place where the treasure is hidden must be cleared of dryness. This treasure is perishable when it encounters the tide, and it is invaded, and it is not damaged in the ground. It is also feared that it will be changed. Therefore, it is hidden in the house, so that the surroundings are transparent, and the ground needs to be high, so as to prevent the earth from rising. If it is stored in the tide, the day is tired and the month is tired, and the armor will be produced, and it will be made with it, and the utensils will be made into a good product.

Second, the C, C, C, 3 - Four. All of them are precious and sensitive. On the way, there are bumps and shocks in the place to avoid, if the package is not solid, there is a risk of friction and collision. Therefore, the outer package should be made of materials, and the package should also be made of soft materials to protect it from the damage of the shock.

Third, the person who holds it has the ability to support it. The existence of the problem is not something that can be done by hand. Those who are familiar with the nature of this problem are familiar with it, and they can understand it in a small way. If there is a little bit of a problem, they will act quickly; those who are not good also need to abide by the rules, and they should not act rashly. If it is not used by others, it is easy to cause trouble, or cause a problem, or cause an accident.

Fourth, it is clear that it cannot be missed. The amount hidden in it, the way in and out, and the way of travel are all important. First, it is easy to check and prevent theft and loss; second, if there is a problem, it can be traced back to the root cause and the way to solve it. If it is not clear, things will not be mixed up. Once something happens, it is difficult to check and add to the difficulty.

Of them, C, C, 3-4. All need to pay attention to the storage and storage of A, and do not slack off, so as to keep its quantity for other days.
