| Abstract: | A flame retardant 9,10-dihydro-9-oxa-10-phospha-phenanthrene-10-oxide （DOPO） was synthesized by phosphorus trichloride, o-phenylphenol as starting materials and zinc chloride as catalyst. The yellow by-products were analyzed and the structures were determined, their formation were effectively inhibited by optimizing the synthesis process. The purity of DOPO was above 99.5%, and it would meet the requirements and applications. |
