3-Pyridinemethanamine, what are the synthesis methods of N-ethyl-
To prepare 3-pyridylmethylamine, N-ethyl, it is often done by number method.
First, 3-pyridylformaldehyde can be started from 3-pyridylformaldehyde. First, 3-pyridylformaldehyde and ethylamine are condensed under suitable conditions to obtain imine intermediates. Then a reducing agent, such as sodium borohydride or lithium aluminum hydride, is applied to the imine and reduced, and the product of 3-pyridylmethylamine and N-ethyl is obtained. In this process, the control of the reaction conditions is the key. During the condensation reaction, the choice of temperature and solvent affects the reaction rate and yield. If the temperature is too high, side reactions are easy to occur; if the temperature is too low, the reaction is slow. The solvent used needs to be well-soluble in the reactants and does not react with the two. In the reduction step, the amount of reducing agent should also be accurate. If the amount is small, the reduction will not be complete, and if the amount is large, the cost will be increased, and other side reactions may be induced.
Second, 3-pyridinecarboxylic acid is used as a raw material. First, 3-pyridinecarboxylic acid is converted into the corresponding acid chloride, which is often achieved by reagents such as sulfoxide chloride. The resulting acid chloride reacts with ethylamine to form an amide. Subsequently, with a strong reducing agent, such as lithium aluminum hydride, the amide is reduced to 3-pyridinecar In this path, the preparation of acid chloride needs to be in an anhydrous environment, because the acid chloride is hydrolyzed in contact with water. The amide reduction step also needs to be strictly anhydrous, and the reaction temperature and time need to be fine-tuned to obtain the best yield.
Third, 3-halopyridine can also be started from 3-halopyridine. React 3-halopyridine with ethylamine and a suitable base in an organic solvent. The function of the base is to capture the hydrogen halide formed by the reaction of halopyridine and ethylamine, and shift the reaction equilibrium to the right. In this reaction, the halogen atom activity of halopyridine, the strength and dosage of the base, the reaction temperature and time all affect the product formation. The halogen atom has high activity and is easy to react; however, if the activity is too high, it may cause side reactions. The strength of the base also needs to be adapted. If it is too strong, it will cause the decomposition of the substrate, and if it is too weak, the reaction will be difficult to continue.
All kinds of preparation methods have their own advantages and disadvantages. In actual preparation, according to the availability of raw materials, cost, product purity and other factors, careful selection and fine regulation of the reaction conditions are expected to obtain high yield and high purity 3-pyridylmethylamine, N-ethyl products.
3-Pyridinemethanamine, N-ethyl-What are the precautions in storage and transportation?
3-Pyridylmethylamine, N-ethyl - Many things need to be paid attention to when storing and transporting this substance.
First, it is related to storage. Because of its nature, it may be active and easy to react with other substances, so it must be stored in a cool, dry and well-ventilated place. Keep away from fire and heat sources to avoid danger. Be sure to store it separately from oxidants, acids, etc., and must not be mixed. Because of contact with it, it may react violently and cause safety risks. The storage area should be equipped with suitable materials to contain leaks to prevent accidents.
Second, when transporting. Make sure that the container is well sealed to prevent leakage. Transport vehicles must be equipped with the corresponding variety and quantity of fire equipment and leakage emergency treatment equipment. During driving, it should be protected from exposure to the sun, rain, and high temperature. When transporting by road, drive according to the specified route, and do not stop in residential areas and densely populated areas. When transporting by rail, do not slip away. When loading and unloading, the operation should be light and light to prevent damage to packaging and containers.
This is the key to ensuring the safety of 3-pyrimethylamine, N-ethyl-in storage and transportation. A little negligence can lead to disaster, so everything needs to be treated with caution.
