Abstract
Chromosulfuric acid, which is used in many organic reactions as an oxidizing agent, can advantageously be regenerated electrochemically if an electrolysis cell is used which comprises two tub-like half shells with a current-permeable, hydraulically sealing partition situated inbetween. The hydrogen produced at the cathode can also be extracted and utilized in this way.
