Phosphorus trichloride

HS v2017 Code: 281213

About phosphorus trichloride

HS code 281213 covers phosphorus trichloride, a chemical compound with a wide range of industrial applications. As a key raw material in the production of various phosphorus-based chemicals, phosphorus trichloride plays a crucial role in industries such as agriculture, pharmaceuticals, and specialty chemicals. Its importance extends across the global economy, making it a vital component in the import/export trade landscape.

Production process

Phosphorus trichloride is typically produced through the reaction of white phosphorus and chlorine gas. This process involves carefully controlling the temperature and pressure to ensure the desired chemical reaction takes place. The resulting phosphorus trichloride is then purified and packaged for distribution to various end-users.

Production inputs

The primary inputs required for the production of phosphorus trichloride include white phosphorus, chlorine gas, and specialized production equipment such as reactors, distillation columns, and storage tanks. Additionally, the process may require the use of catalysts, solvents, and other auxiliary materials to optimize the reaction and purification stages.

Production outputs

Phosphorus trichloride is a versatile chemical that serves as a precursor for the manufacture of a wide range of other phosphorus-based compounds. Its primary outputs include 281214 Phosphorus oxychloride, 281310 Phosphoric acid, and various phosphorus-containing pesticides and flame retardants. These downstream products find applications in industries such as agriculture, pharmaceuticals, and specialty chemicals.
