ABSTRACT:
The quality of a product predominant in tetrabromobisphenol-A is enhanced by contacting the product with a quality enhancing amount of treated water and heat treating the product for a period of time and at a temperature which are sufficient to obtain a TBBPA predominant product having less than about 20 ppm of ionic impurities.
