Abstract
Bisphenol-A bis(diphenyl phosphate) was synthesized from phosphorus oxychloride bisphenol-A and phenol.The effects of process parameters,such as molar ratio,reaction temperature and catalyst on the yield were studied respectively,the suitable synthesis conditions were 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.AlCl_3 was the best catalyst,and its dosage was 2% of the amount of all bisphenol-A.The yield reached 88.7%.The structure of the product was defined by FT-IR.The quality of the product can reach the indexes of the oversea product.The flame retardance was tested in different plastic product,which showed that the bisphenol-A bis(diphenyl phosphate) was a good flame retardant.
