摘要:
This invention relates to a process for isolation of partially brominated diphenyl ether mixtures ("Octabrom") having an average bromine content of 7.2-8.5. The process comprises: (i) adding a C.sub.1 -C.sub.4 alkanol to the Octabrom in solution in an organic solvent; (ii) maintaining the contact of the alkanol with Octabrom in the organic solvent for that period of time which is sufficient to allow the Octabrom to precipitate in crystalline form, making a slurry; and (iii) recovering the final Octabrom from the slurry.
