摘要: The invention relates to a preparation method of bis(PEPA) phenylphosphonate compound. This compound has structural formula shown as below, and the comprises: in an organic solvent, reacting phenyl phenylphosphonic dichloride with PEPA sodium salt or zinc salt, purifying obtain white solid, phenylphosphonate. product is useful flame retardant for materials such polyester PBT, PET, polypropylene PP polyester. simple process, reaction time short, conditions are mild, selectivity good, yield high, no hydrogen chloride pollution occurs, separating easy, equipment corrosion low, investment easy large-scale production.
