ABSTRACT:
A liquid slurry of submicron particles of hexabromobenzene is prepared by vaporizing hexabromobenzene in a first zone, transporting the vapors to a second zone by use of an inert carrier gas, condensing the vapors in a second zone so as to form a liquid slurry, and thereafter recovering the slurry formed. The product particles are particularly effective when used as a fire retardant in an acrylic fiber having high luster requirements.
