During the electrochemical reduction of a mixture of nitronaphthalenetrisulfonic acids, 1-aminonaphthalene-3,6,8-trisulfonic acid (the T-acid) is formed on the lead cathode. However, with increase in the temperature, the rate of corrosion of the lead cathode increases considerably. Therefore, to carry out the electrochemical synthesis of the T-acid at higher temperatures, as well as at increased current density, it is necessary to seek a cathode material having a higher corrosion resistance than lead. In this paper, a lead-antimony alloy with a 9-13% content of antimony, which in its composition corresponds to a standard alloy, brand SSu 10 GOST 1282-74, is tested recommended as a cathode material for the intensification of the conditions of the electrochemical synthesis of the T-acid.
