Abstract:
In th is paperw as reported a me thod o fm ak ing resorcin phosphate as flam e retardant from pheno ,l resorc in and phosphous oxych lo ride, w as stud ied the influence such factors as m o le ration, tem pe rature and cata lyst have on the reac tion, and w as estab lished the best reaction cond ition: Themo lar ra tio o f phosphous oxychlor ide and resorcin is 2. 2：1. In the first step, the reaction temperature is 60℃ , and the reac tion time is 6 hours. In the second step, the reaction tem pe ra ture is 130℃ , and the reaction tim e is 8 hours. A lC l3 is the best cata lyst. Its dosage is 2% o f the tota l am ount o f a ll reactants in the first step. The y ie ld reaches 90%. The flam e retardance has been tested in differ ent p lastic product, wh ich show s tha t resorc in phospha te is a good flam e reta rdant.
