One hundred and thirty-eight grams of the crude tris(2,4-dibromophenyl)phosphate were dissolved in 392 grams of a 80/20 mixture of n-heptane and toluene at 90° C. The mix was cooled to room temperature whereupon a thick slurry of product and solvent were separated in a stainless steel basket centrifuge. Two hundred and sixty-nine grams of solvent were recovered as mother liquor from the separation. Evaporation and handling losses were high. This solution contained 2.4% solids consisting of 0.7% 2,4-dibromophenol, 0.4% chloridates, 0.26% 2,6 and 2,4,6 substituted bromophenols and 2.3% product.
