| titleOfInvention | Method for producing 1,3,6,8-tetrabromopyrene |
| abstract | (57) [Abstract] [Purpose] Eliminate environmental problems as much as possible in consideration of avoiding high-temperature reaction with organic solvent in bromination of pyrene, not using elemental bromine, and omitting grinding step of aqueous dispersion of pyrene. And to provide a method for producing 1,3,6,8-tetrabromopyrene which is industrially safe to operate. [Structure] Bromide was added to an aqueous dispersion of pyrene, and an oxidizing agent was added thereto under mineral acidity to prepare 1,3,6,8- Tetrabromopyrene is produced. A wetting agent or dispersant is added to the mineral acid acidic dispersion of pyrene and treated for a short time under heating to prepare an aqueous dispersion of pyrene. |
