Procedure

A mixture of 100 g of fumaric acid, 201 g of a 48% aqueous solution of caustic potash and 1370 g of water was subjected to reaction conducted in the same manner as illustrated in Example 10 to obtain an aqueous solution of potassium fumarate having a pH value of 10.5 and containing 10.3% by weight of a solid matter. To this aqueous solution of potassium fumarate was added an aqueous solution of 308 g of silver nitrate in 300 g of water to effect a double decomposition reaction in the same manner as illustrated in Example 10 whereby 275 g of silver fumarate was obtained which had a silver content of 61.3% by weight.
