Abstract
Apparatus and method for the electrochemical reduction of a nitroaromatic to a dye includes a housing divided into two sections by membrane. An electrolyte solution including a non-aqueous electrolyte dimethylformamide and a supporting electrolyte is provided to the two sections of the housing. A cathode is located in one section of the housing while an anode is located in the other section. A nitroaromatic is provided to the section having the cathode. A direct voltage is provided to the cathode and to the anode so that a current can pass and cooperate in a reaction between the nitroaromatic and the electrolyte solution to provide a dye.
