Participants

Conditions

Temperature: 80 °C

Procedure

1.58 g (10.0 mmol) of phenylphosphonic acid (manufactured by Nissan Chemical industries, Ltd.), 2.20 g (10.0 mmol) of zinc acetate dihydrate and 72 g of water were mixed, stirred at 80° C. for 3 hours, then the resulting slurry was filtered, acetic acid in the wet cake was fully washed away with water, and thereafter, dried at 150° C. to obtain 2.17 g (yield 98%) of the aimed product as white crystal. Decomposition temperature: 541° C. The average particle diameter was 4.4 μm with a laser diffraction type particle size distribution meter (manufactured by Seishin Enterprise Co., Ltd., PRO-7000S).
