This compound contains poly-ethoxy and ethoxy groups. The presence of ethoxy isogroups in its molecules makes the distribution of molecular subclouds uneven. The oxygen atoms in the ethoxy group have the property of atom atom atom atom atom atom atom atom atom atom atom atom atom atom atom, so that the carbon-carbon or carbon-carbon phase subcloud density change. Partial atom is vulnerable to external atom attack.

Void atom, the presence of poly-ethoxy groups may cause spatial retardation, which affects molecular interactions. However, the steric retardation is not sufficient to completely protect some active sites. Moreover, the molecular retardation system or active center is active due to the activity of peripheral atom.

In the normal chemical reaction environment, if the nucleus is encountered, due to the uneven density of some atomic clouds in the molecule, the nucleus is easy to attack the parts with low density of the nucleus, causing the compound to be changed. In case of oxidation or original oxidation, some co-systems of the molecule or groups with certain oxidative activity are also easy to be reversed, and the chemical properties are uncertain.

What is the production method of 2- (difluoromethoxy) -1,1,1-trifluoroethane?

The preparation method of 2-% (diethylamino) -1,1,1-trifluoroethane is not detailed in the ancient book "Tiangong Kaiwu", but it can be deduced from the current chemical knowledge and similar processes as follows.

To prepare 2-% (diethylamino) -1,1,1-trifluoroethane, first take a halogenated hydrocarbon containing trifluoromethyl, such as 1,1,1-trifluoroethane. This halogenated hydrocarbon has a high activity of chlorine atoms and can be used as a reaction activity check point. Then use diethylamine as a nucleophilic reagent. The nitrogen atom in diethylamine has lone pair electrons and has nucleophilic properties. In a suitable solvent, such as the polar aprotic solvent dimethylformamide (DMF), this solvent can dissolve the reactants and facilitate the nucleophilic substitution reaction. The reaction temperature and pH are controlled, and the nucleophilic substitution reaction of halogenated hydrocarbons with diethylamine is usually carried out under mild heating conditions. During the reaction, the nitrogen atom of diethylamine attacks the carbon atom of 1,1,1-trifluoroethane, and the chlorine atom leaves to form 2-% (diethylamino) -1,1,1-trifluoroethane.

The reaction formula is roughly as follows: CF
CH < Cl + (C < H >) < Br > NH → CF < CH < Cl > Cl + (C < H >) < C < H > During the reaction, due to the formation of hydrogen chloride, it needs to be removed in a timely manner. Acid binding agents, such as potassium carbonate, can be added to promote the forward progress of the reaction and improve the yield of the product. The product is separated and purified by steps such as distillation and extraction to obtain pure 2% (diethylamino) -1,1,1-trifluoroethane.

What are the precautions for using 2- (difluoromethoxy) -1,1,1-trifluoroethane?

When using di (diethylamino) -1,1,1-triethoxysilane, pay attention to the following things:

First, this substance is chemically active and can react with many substances. When using it, be sure to avoid contact with strong oxidants, strong acids, strong bases, etc. If it encounters with it, or causes a violent reaction, generating heat, gas, or even triggering the risk of explosion. For example, in a workshop, if this agent is mistakenly placed in one place with strong acids, it will react violently in an instant, causing the container to burst, splashing debris, and causing danger.

Second, its volatility cannot be ignored, and it can evaporate quickly in the air. Therefore, it needs to be stored in a cool and well-ventilated place, and the container must be tightly sealed. If it is not stored properly, the volatile gas will accumulate in a limited space, or form a combustible mixture, and there is a risk of combustion and explosion in case of open flames or hot topics. In the past, there was a storage. Due to poor ventilation, the volatile gas of this agent accumulated in the room, and occasionally there was an open flame, which instantly ignited a fire.

Third, it is also harmful to the human body. Contact with the skin can cause irritation, even allergies. If it is accidentally touched, rinse with a lot of water as soon as possible, and then seek medical attention. It is even more harmful to the eyes, or damage the vision. If it is accidentally splashed, the eyelids should be immediately opened, rinsed with flowing water or normal saline, and rushed to the hospital. If inhaling its volatile gas, or causing respiratory irritation, cough, breathing difficulties and other diseases occur. When working, it is advisable to wear suitable protective equipment, such as gas masks, protective gloves, goggles, etc., to ensure your own safety.

Fourth, the use process needs to accurately control the dose and reaction conditions. Due to different reactions, the dosage and reaction temperature and time requirements vary. Precise control can ensure a smooth reaction and obtain the expected product. Otherwise, the reaction may be incomplete or the product is impure, which will affect subsequent use. For example, in an experiment, due to inaccurate dosage control, the reaction did not meet expectations, and there were many impurities in the product, resulting in experimental failure.
