The article is dedicated to synthesis of some nitrous reproductions of oil acids (OA) and to the study of their inhibitor properties against corrosion of steel. With this purpose 90-1100C/266,644 Pa, 110-1200C/266,644 Pa and 120-1300C/266,644 Pa fractions were decomposed from fractionation of distilled OA (DHT, ГОСТ 13302-72) and their having the same composition was determined. Further inhibitor properties of amides and ammonium salts derived on the basis of reactions of 110-1200C/266,644 Pa OA with ethanolamine and ethylendiamine were studied. It was found that under the defined situation protection effects of ammonium salts against corrosion makes і99%. Resulting findings allow to propose using salts of 90-1300C/266,644 Pa OA fraction with ethanolamine as inhibitor against corrosion of steel.
