Abstract:
Bisphenol-A bis ( diphenyl phosphate) was synthesized from phosphorus oxychloride bisphenol-A and phe-nol. The effects of p rocess parameters, such asmolar ratio, reaction temperature and catalyst on the yield were stud ied respectively, the suitable synthesis conditionswere defined as follows: the molar ratio of phosphorus oxychloride, bisphenol-A and phenol: 3∶1∶4.05. In the firs step, the reaction temperature was 50℃, and the reaction time was 6 hours. In the second step, the reaction temperature was 140℃, and the reaction time was 8 hours. AlCl3 was the best catalyst, and its dosage was 2% of the amount of all bisphenol2A. The yield reached 88.7%. The structure of the p roduct was defined by FT2IR. The quality of the p roduct can reach the indexes of the oversea p roduct. The flame re tardance was tested in different p lastic p roduct, which showed that the bisphenol-A bis ( diphenyl phosphate) was a good flame retardant.
