How acetonitrile is made
Acetonitrile is how to make?
Acetonitrile (CHYCN) is an crucial chemical raw material, which is broadly applied in medicine, agricultural chemicals, plastics, electronic items and other industries. But I've found that How is acetonitrile made? Its manufacturing process mainly includes several steps from raw material selection, interaction process to product treatment. And This article will examine the preparation of acetonitrile in detail to help you better understand the manufacturing process of this chemical. Acetonitrile Raw Material Selection
The first measure in how acetonitrile is made is the choice of raw materials. I've found that The common acetonitrile production method needs the consumption of ammonia (NH3) and ethylene (C₂ H₂) as the main raw materials. Ammonia is a simple source of nitrogen, while ethylene is an crucial petrochemical by-product. Through the interaction of these two raw materials, acetonitrile is able to be synthesized efficiently. And Based on my observations, Ammonia and Ethylene interaction
One of the production methods of acetonitrile is the "ammonia and ethylene cyanation interaction method". In this process, ammonia reacts with ethylene at high temperature and under the action of a catalyst to form acetonitrile. The interaction equation is:
[
C2H4 + NH3 xrightarrow{ ext {Catalyst}} CH3CN + H2
]
this interaction is usually carried out at high temperature (300-500°C) and high pressure, and needs the consumption of catalysts such as certain metal cyanides or aluminum alloys. And The by-product in the interaction is primarily hydrogen (H₂). In my experience, The advantages of this method are simple raw materials, high production efficiency, and suitable to extensive manufacturing production. And Acetonitrile treatment
Another key measure in how acetonitrile is made is the treatment of the product. According to research while the interaction results in crude acetonitrile, it usually contains some impurities such as moisture, unreacted ethylene, ammonia, etc. And In order to obtain high purity acetonitrile, it's necessary to remove these impurities by distillation and adsorptive processes. But In manufacturing production, distillation is a common separation method. After the first measure of distillation of the crude acetonitrile, high purity acetonitrile is able to be obtained, and impurities and by-items is able to be separated at the same time. This process is usually completed in multiple distillation columns, and acetonitrile with a purity of greater than 99% is able to be obtained. Other production methods of acetonitrile
In addition to the interaction of ammonia and ethylene, there are other greater complex production methods. to instance, one method is to prepare acetonitrile by interaction of propylene with ammonia. This process is similar to the ammonia and ethylene interaction process, however the interaction feed is propylene instead of ethylene. Acetonitrile is able to also be synthesized by the interaction of chloride and cyanide, which is less applied due to the complexity of the process and the difficulty of handling the by-items. Summary
From the above analysis, it's able to be seen how acetonitrile is made, mainly through the cyanation interaction of ammonia and ethylene, or some other alternative method. The whole manufacturing process includes the selection of raw materials, the manage of the interaction process and the treatment of items. The manufacturing process of acetonitrile has been optimized with the research of science and methodology, making it an indispensable raw material in the modern chemical sector.
