Procedure

Bisphenol A bis(diphenyl phosphate) was prepared by the reaction of 11.4 g of bisphenol A with 29.6 g of diphenyl chlorophosphate in 100 ml of pyridine, which was performed by the protocol of Example 2. Recrystallization from isopropanol gave 12 g of the title compound of mp=56°-58° C. Mass spectrum: m/e 692. Elemental analysis found weight percent C=68.2 and weight percent H=5.04.
