Abstract (en)

[origin: WO9425451A1] Disclosed are high-solids processes for producing N,N'-bis(tetrabromophthalimide) and/or N,N'-alkylene-bis(tetrabromophthalimide) products useful as flame retardants. The processes are performed in high-mass transfer reactors similar to apparatuses conventionally used as mixers/dryers for particulate solid materials.
