実験手順

50 g of monocetylphosphoric acid and 100 g of ethanol were put into a 500 ml reaction vessel. Further, a solution of 6.29 g of 96% sodium hydroxide (purity was taken into consideration by calculating it from the degree of neutralization determined by titration) dissolved in 200 g of ion-exchanged water was added thereto. After the temperature was elevated to 80° C., it was confirmed that they were clearly dissolved. The solution was continuously stirred for 30 minutes. A solution of 22.3 g of zinc sulfate heptahydrate dissolved in 100 g of ion-exchanged water was added dropwise thereto to carry out a salt exchange reaction. After the completion of the addition, the mixture was stirred for 2 hours. The pH of the reaction mixture was 1.35 at the end of the reaction. The mixture was cooled and the product was collected by filtration, washed with water and dried, to obtain 51.4 g of the particles of zinc monocetylphosphate (zinc/sodium/phosphorus=0.88/0.49/2.00).
