    摘要: PROBLEM TO BE SOLVED: To provide a high quality tetrabromobisphenol-A with a high yield. SOLUTION: The method for producing tetrabromobisphenol-A comprises forming a reaction system where tetrabromobisphenol-A precipitates directly by the bromination of bisphenol-A in such a velocity that does not give tribromobisphenol-A as an intermediate a chance sufficient to precipitate in a significant amount. The whole precipitate produced in the process contains at least 96 wt.% tetrabromobisphenol-A. COPYRIGHT: (C)2008,JPO&INPIT
