- Description
- The explosion occurred in a chemical plant manufacturing raw materials for cosmetics. Fluoro-nitro-benzene and liquid chemicals were mixed in a high-pressure reactor for the development of a new product. Hydrogen gas was then injected. During the production process, about 12 hours after the start of the reaction, an abnormal reaction occurred and the reactor exploded due to a sudden increase in pressure.

- WHAT IS FLUORONITROBENZENE
Fluoronitrobenzene is an organic compound with the formula FC6H4NO2.
It can be hydrogenated to give 4-fluoroaniline, which is a precursor to fluoroimide (a fungicide) and to parafluorofentanyl (an opioid).
