Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a non-cyanide gold compound having no cyan useful as a gold source for non-electrolytic and electrolytic plating liquid.SOLUTION: There is provided a white powdery crystal of a non-cyanide gold compound by suspending alkali metal salts such as first gold chloride, sodium chloride and potassium chloride and 2-mercaptobenzothiazoles in an aqueous solution, then reacting them under a condition of pH of 7.0 to 13.5 and temperature of 10 to 90°C in a presence of inert gas, column purifying deposited crystal by benzene after a reaction end to coordinate 2-mercaptobenzothiazoles to a gold ion represented by the general formula (1). (1), where Rto Rare H, a halogen atom, -CH, -OCHor -NO.SELECTED DRAWING: None
