Abstract

The electrochemical reduction of dinitronaphthalene to produce diaminonaphthalene has been optimized. The synthesis of diaminonaphthalene by the electrolysis of a suspension of dinitronaphthalene in sulphuric acid with a titanium salt gives a yield and purity similar to the synthesis by catalytic hydrogenation. Technical and economical comparisons of the two processes show that for large capacities (several hundred tons per year), reduction by catalytic hydrogenation is more feasible. However, for smaller quantities (several tons per year) the flexibility of exploitation by electrolysis has economic advantages.
