Development of production technology of imidazoline corrosion inhibitors

Resumo

Imidazoline corrosion inhibitors of have been prepared from vegetable oil industry waste and polyethylenepolyamide. The protective ability and corrosion rate of the imidazoline products have been determined via gravimetric and energy-dispersive X-ray fluorescence spectral analysis methods. The best protective effect is at corrosion rate of 0.2 g/(mm² h). The imidazoline products based on the vegetable waste feedstock meet the main characteristics of commercial analogue, thus holding promise for using them as a component of industrial corrosion inhibitors.
