4-Aminomethylpyridine, which is 4-aminomethylpyridine, is prepared as follows:
First, 4-cyanopyridine is used as raw material. First, 4-cyanopyridine is reacted with an appropriate amount of reducing agent, such as lithium aluminum hydride (LiAlH), in an organic solvent such as anhydrous ether, at a low temperature and in a strictly anhydrous and oxygen-free environment. In this reaction, lithium aluminum hydride is used as a strong reducing agent to reduce cyano (-CN) to aminomethyl (-CH -2 NH -2). After the reaction is completed, 4-aminomethylpyridine can be obtained through post-treatment steps such as hydrolysis.
Second, 4-pyridine methanol is used as the starting material. 4-Pyridyl methanol is reacted with a suitable ammonia reagent, such as ammonia (NH
), in a high-temperature and high-pressure reactor in the presence of a catalyst, such as aluminum oxide (Al < unk > O <). The hydroxyl group (-OH) of 4-pyridyl methanol is replaced by ammonia (-NH < unk >), resulting in 4-aminomethylpyridine. After the reaction is completed, the product is separated and purified by distillation.
Third, pyridine, formaldehyde and ammonia are used as raw materials. Under the action of specific catalysts, such as acidic ion exchange resins, pyridine reacts with formaldehyde and ammonia in Mannich. Formaldehyde and ammonia condensate to form imine ion, and then the 4-position of pyridine undergoes nucleophilic addition reaction with imine ion to form 4-aminomethylpyridine. After the reaction, the products are separated by extraction and other methods.

4-Aminomethylpyridine, the price in the market is difficult to determine. This is due to various reasons, resulting in its price changing. Its price is related to supply and demand. If there are many people who want it, if the supply is small, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
It is also related to the production method and cost. If the production method is easy, the raw materials are easy to obtain and cheap, and the price is low; if the production method is difficult, the raw materials are rare and the cost is high, the price will be high. Furthermore, the competition in the market also has an impact. There are many sellers, who compete for customers, or reduce the price to promote sales; if there are few sellers, or control the quantity and increase the price.
Looking at the market conditions in the past, the price ranged from tens to hundreds of yuan per kilogram. However, this is only a rough figure, not an exact value. At this moment, if you want to know the exact price, you can get an accurate number when you visit the chemical material merchants or observe the real-time quotations of the market. The market is impermanent, and the price changes at any time. Only by observing the present can you know the true price.
