Decanoic Acid → Silver(1+) decanoate

Participants

Reaction Steps

A solution prepared by dissolving 11 g of capric acid in 100 ml of butyl acetate was mixed with a solution prepared by dissolving 1.8 g of sodium hydroxide in 150 ml of water and, further, 0.25 g of ammonium bromide and 0.02 g of ammonium iodide were added thereto, followed by stirring with a homogenizer at 1500 rpm to emulsify the system. While stirring, an aqueous solution prepared by dissolving 8.5 g of silver nitrate in 50 ml of water was added thereto to yield both silver halide and silver caprate. This reaction system separated into two phases when allowed to stand. An aqueous phase, one of the two phases, was removed, and the remaining butyl acetate phase containing silver caprate and silver halide (silver caprate: ca. 1/20 mol, AgX: ca. 2.5×10-3 mol) was dispersed in a 15 wt% isopropanol solution of polyvinyl butyral to prepare a polymer dispersion of the silver salts. This solution was referred to as dispersion K.
