Decanoic Acid → Silver(1+) decanoate

反応手順

A solution of 11 g of capric acid dissolved in 100 ml of butyl acetate was mixed with a solution of 1.8 g of sodium hydroxide dissolved in 150 ml of water, and 0.25 g of ammonium bromide and 0.02 g of ammonium iodide were then added thereto, all at 25° C. The resulting mixture was stirred by a homogenizer rotating at 1,500 r.p.m. to emulsify the mixture. While stirring, an aqueous solution of 8.5 g of silver nitrate dissolved in 50 ml of water was added to the emulsion to form silver bromoiodide and silver caprate at 25° C. When the reaction system was allowed to stand, it separated into two phases. After the aqueous phase was removed, the butyl acetate phase containing silver caprate and silver bromoiodide was dispersed in 180 g of a 15 wt % isopropanol solution of polyvinyl butyral to prepare a polymer dispersion of the silver salts, which was designated mixture C.
