Abstract:
Provided is a method of preparing a biphenyl-4-yl diphenyl phosphate composition for use as a flame retardant or a plasticizer for resin, including mixing phosphoryl chloride (POCl3), 4-phenylphenol, and a catalyst, so that first dehydrochlorination occurs; and further adding phenol, so that second dehydrochlorination occurs.
