It is proposed to use plant and animal raw materials to produce corrosion inhibitors of oil refining equipment. The corrosion inhibitors based on vegetable oil and animal fat with diand triethanolamine have been synthesized, nitrogen-containing corrosion inhibitors have been obtained, their physical and chemical parameters have been determined. By using the gravimetric method the protective effect of the received inhibitors was determined on St20 steel in a two-phase corrosive environment simulating the preliminary preparation conditions of oil at electro-salting and dehydration plants. It was shown that inhibitors on the basis of plant and animal raw materials, obtained under certain synthesis conditions, are able to protect the metal surface of oil refining equipment.
