PROBLEM TO BE SOLVED: To provide a manufacturing method of a gold compound having no cyan available as a gold source for non-electrolytic and electrolytic plating liquid.SOLUTION: There is provided a non-cyanide gold compound represented by the general formula (1), which is a white powdery crystal obtained by suspending alkali metal salts such as sodium first gold compound chloride synthesized form chloroauric acid, 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 such as argon gas or nitrogen gas, column purifying deposited crystal by benzene after a reaction end. The non-cyanide gold compound is available as a gold source for non-electrolytic and electrolytic plating liquid having no cyan in a plating bath. General formula (1), where Rto Rare H, a halogen atom, -CH, -OCH, -NO.SELECTED DRAWING: None |
