What is the production process of 2,2,4-trimethyl-1,2-dihydroquinoline polymer?

Ethylene, which is unsaturated, can be used to prepare many organic compounds. Monocarbon and dihydrogen, which are methyl structures, are often fragments of organic molecules. As for the preparation process of diaminodistyrene compounds, the method is quite delicate.

To prepare this compound, compounds containing benzene rings are often used as starting materials. The benzene ring is first introduced into the amino group, which can be nitrified and reduced. During nitrification, a mixed acid of concentrated nitric acid and concentrated sulfuric acid is used as a reagent, and at a suitable temperature, the benzene ring is nitrified and nitro groups are introduced. Then iron filings and hydrochloric acid are used as reducing agents to reduce the nitro group to amino groups.

Then, the skeleton of the stilbene needs to be constructed. Often with the help of the Wittig reaction or the Heck reaction. In the Wittig reaction, phosphorus is obtained by reacting halogenated hydrocarbons with triphenylphosphine, and then reacting with aldose or ketone, a carbon-carbon double bond can be formed to construct a stilbene structure. If the Heck reaction is used, the halogenated aromatics and olefins are used as raw materials. Under the action of palladium catalyst and base, the coupling of carbon-carbon bonds is realized to form a stilbene skeleton.

Finally, through appropriate reaction conditions, the amino group is connected to the stilbene structure, and then the diaminodistyrene compound is obtained. In this process, it is necessary to carefully control the reaction temperature, time, reagent dosage and other factors to ensure the purity and yield of the product. The preparation process is complicated, but through exquisite design and operation, high-quality products can be obtained.

What are the precautions for the use of 2,2,4-trimethyl-1,2-dihydroquinoline polymers?

2% 2C2% 2C4 should refer to diethylamine, which is an organic base and is corrosive and irritating. 1% 2C2 or dichloroethane is a toxic and volatile organic solvent. These two are involved in the synthesis of diethylamino dichloroethane, and there are many precautions in use:
First, it is related to safety protection. Diethylamine is highly corrosive and irritating, and can cause burns to the skin, eyes and respiratory tract. To use it, you need to wear protective clothing, protective gloves and goggles. It should be operated with good ventilation and respiratory protective equipment if necessary. Dichloroethane is toxic and volatile. It is harmful to inhalation, ingestion or percutaneous absorption. It also needs to be protected to avoid skin contact and inhalation of volatile gases.
Second, it involves operating specifications. For reaction operation, it is necessary to precisely control the reaction conditions. Due to the strong alkalinity of diethylamine and the high chemical activity of dichloroethane, the reaction may be violent. The reaction temperature and feeding speed should be strictly controlled to prevent loss of control. At the same time, in view of the volatility of the two, the reaction device should be well sealed and matched with an exhaust gas treatment device to prevent gas from escaping and polluting the environment and endangering health.
Third, it is related to storage points. Diethylamine should be stored in a cool and ventilated warehouse, away from fire and heat sources, and stored separately from oxidants and acids to avoid danger caused by mixed storage. Dichloroethane should also be stored in a cool and ventilated warehouse, away from fire and heat sources, and stored separately from oxidants, acids and alkalis.
Fourth, pay attention to emergency treatment. If accidentally exposed to diethylamine, skin contact should immediately remove contaminated clothing and rinse with a large amount of flowing water for at least 15 minutes; eye contact should immediately lift the eyelids, rinse thoroughly with a large amount of flowing water or normal saline for at least 15 minutes, and seek medical attention in time. If exposed to dichloroethane, similar emergency treatment should be carried out according to the corresponding contact route to ensure the safety of personnel.
