摘要:
The invention relates to a process for preparing a solution of a non-ferrous metal sulphonate by reacting a non-ferrous metal with a sulphonic acid, the non-ferrous metal being brought into contact with a sulphonic acid at a temperature of from 20.degree. to 120.degree. C. in the presence of oxygen or oxygen-containing gases.
