Procedure

An aqueous slurry of zinc oxide was prepared by charging a 300 mL reaction flask equipped with a stirrer with 10.0 g (123 mmol) of zinc oxide (JIS grade 2, available from HakusuiTech Ltd.) and 90.0 g of water. An aqueous solution of 13.6 g (86 mmol) of phenylphosphonic acid (available from Nissan Chemical Industries, Ltd.) dissolved in 77.0 g of water was gradually added dropwise at room temperature (about 25° C.) to this slurry with stirring, thereby effecting a reaction for one hour. The slurry was then filtered, and the wet cake was thoroughly rinsed with water. The wet cake was subsequently dried at 120° C. for at least 12 hours, yielding a white powder of zinc phenylphosphonate-containing zinc oxide.
