PROBLEM TO BE SOLVED: To provide a novel method for producing a gold compound free from cyanogen available as a gold supply source for electroless and electrolytic plating liquids or usable as a material for a gold resinate paste.SOLUTION: The gold compound can be produced in a good yield by adjusting an aqueous solution of a gold compound represented by formula (1) to a pH of 7.0 to 14.0 and keeping the temperature at 0 to 100°C, adding to the solution a solution dissolving an organic compound having a thiol group in an aqueous solution of one kind or two or more kinds selected from sodium hydroxide, potassium hydroxide and calcium hydroxide and reacting them for 1 to 15 minutes.SELECTED DRAWING: None |
