Solid-state highly brominated compounds such as solid brominated flame retardants with bromine contents of at least about 60 wt% often contain occluded bromine. Because of their high bromine contents, such compounds have relatively low solubility in common organic solvents. Despite this low solubility, the content of occluded bromine in such solid brominated compounds is effectively reduced by agitating a concentrated agitated slurry of the compound in an inert solvent at a suitable temperature for at least about 1 hour. Thereafter, solids with reduced content of occluded bromine are isolated or recovered from the slurry. Novel products having substantially reduced or eliminated occluded bromine contents and other very desirable characteristics are also provided.

L'invention concerne des composés fortement bromés à l'état solide, tels que des retardateurs de flamme bromés solides ayant une teneur en brome d'au moins environ 60 % en poids, qui contiennent souvent du brome occlus. En raison de leur teneur élevée en brome, de tels composés ont une solubilité relativement faible dans des solvants organiques communs. Malgré leur faible solubilité, la teneur en brome occlus dans de tels composés bromés solides est réduite de manière efficace en agitant une suspension agitée concentrée du composé dans un solvant inerte à une température appropriée pendant au moins environ 1 heure. Par la suite, les particules solides ayant une teneur réduite en brome occlus sont isolées ou récupérées à partir de la suspension. De nouveaux produits ayant une teneur en brome occlus sensiblement réduite ou éliminée et d'autres caractéristiques très souhaitables sont également fournis.
