Abstract:
A method of producing a silver salt of an organic acid, which comprises:(1) reacting, a solution containing silver ions in water or in a mixture of an organic solvent and water, with a solution or suspension containing an alkali metal salt of an organic acid in water, in a mixture of an organic solvent and water, or in an organic solvent to produce a silver salt of an organic acid, and (2) removing salt byproduct by a desalting step comprising ultrafiltration, wherein a surfactant having a molecular weight of 3000 or less is present during a time period of from before step (1) to before said desalting step (2), and adding a dispersing agent having a molecular weight of more than 3000 after completion of the reaction to form the silver salt of an organic acid in step (1) and before completion of the desalting step (2).
