Abstract

The interaction of additives with the cathode and the interplay of saccharin, 2-butyne-1,4-diol and phthalimide was investigated by determination of the consumption rates (V-c) of the additives, accumulation rates (Va) of the cathodic reaction products and the incorporation of sulfur and carbon in electrodeposits. The main transformation products of saccharin were benzamide, o-toluene sulphonamide and benzylsultame, while phthalimide gave rise to phthalimidine and o-toluene amide. Cathodic reaction products showed the adsorption modes of the additives on electrodeposits. Saccharin and phthalimide in the mixture increased V-c as well as V-a of o-toluene sulfonamide and phthalimidine. 2-Butyne-1,4-diol decreased V-a of o-toluene sulfonamide and phthalimidine and increased the V-a of benzamide and incorporation of sulfur. The increase of V-c and V-a showed a synergistic effect of the additives. The aromatic compounds in the mixture under study increased additive adsorption by the carbonyl group and 2-butyne-1,4-diol increased the adsorption of saccharin by the sulfonyl group.
