An object of the present invention is to provide a high-purity aqueous copper sulfonate solution and a simplified method of producing this solution.
The aqueous copper sulfonate solution of the present invention is characterized in that the copper concentration therein is at least 90 g/L, the content of metal impurities is less than 10 mg/L as metal for each metal impurity, the content of chlorine is less than 10 mg/L, and the sulfonic acid is a sulfonic acid represented by the following general formula
R—(SO3H)n
(in the formula, R represents a lower alkyl group, lower alkylidene group, lower alkylene group, or hydroxyalkyl group and n represents 1 or 2).
本发明的目的是提供一种高纯度的水合硫酸铜溶液和一种简化的生产该溶液的方法。本发明的水合硫酸铜溶液的特点在于其中的铜浓度至少为90克/升,金属杂质的含量每种金属不超过10毫克/升,氯的含量小于10毫克/升,且磺酸是由以下通式表示的磺酸R—(SO3H)n(在该式中,R表示较低的烷基、较低的烷基亚甲基、较低的烷基亚基、或羟基烷基,n表示1或2)。
