After about 5 minutes, the time when insoluble matter disappears in this mixture and the mixture change to dark green transparent solution is decided as finish point of the reaction. However, the reaction mixture is not heated during the reaction. After finish of the reaction, the reactor is stopped and permitted to stand at room temperature (about 20°C) for a whole day and night to precipitate dark green crystals of copper salicilic acid complex dimer. The resulting crystals are separated from the solution by filtration and washed with 50 ml of the above mentioned mixed solvent to obtain 45 g of the aimed product.
