There have been examined azoderivates of double basic acid as inhibitors of acidic corrosion, synthesized on the basis of individual compound (A), and as well as samples formed on the basis of industrial wastes (B and V). It was established that effectiviness of samples of inhibitors, obtained from industrial wastes (B, V), is higher than effectiveness of inhibitor A, synthesized on the basis of individual compound, which gives real possibility for the use of them as inhibitors of steel corrosion in sulphuric and hydrochloric acid.
