Carbonyl dichloride (phosgene)

HS v2017 Code: 281211

About carbonyl dichloride (phosgene)

HS code 281211 covers the classification of carbonyl dichloride, commonly known as phosgene. Phosgene is a highly toxic gas that has been used in various industrial applications, primarily as an intermediate in the production of other chemicals. Despite its hazardous nature, phosgene plays a crucial role in the global chemical industry, contributing to the manufacturing of a wide range of products that are essential for various sectors, including agriculture, pharmaceuticals, and plastics.

Production process

Phosgene is typically produced through the reaction of carbon monoxide and chlorine gas. This process, known as the phosgene synthesis, involves the controlled combustion of these two gases under specific temperature and pressure conditions. The resulting phosgene gas is then purified and stored for further use in various chemical processes.

Production inputs

The main inputs required for the production of phosgene include carbon monoxide and chlorine gas. These raw materials are typically sourced from industrial facilities that specialize in the manufacture of these gases. Additionally, the production process may require specialized equipment, such as reaction vessels, gas handling systems, and purification units, to ensure the safe and efficient production of phosgene.

Production outputs

Phosgene is primarily used as an intermediate in the production of other chemicals, such as 290310 isocyanates, which are essential for the manufacturing of 390000 plastics and 300000 pharmaceutical products. Phosgene is also used in the synthesis of various 290000 organic chemicals and 291000 carboxylic acids, which have a wide range of industrial applications.
