Учитывая актуальность темы, для защиты нефтепромыслового оборудования и трубопроводов от общей и микробиологической коррозии был синтезирован бактерицид – ингибитор комплексного действия. В данной работе представлен анализ результатов научных исследований в области синтеза, изучения свойств и поиска областей применения синтезированных амидов на основе аминов (анилина, бензиламина) и природной нефтяной кислоты (ПНК). Были приготовлены растворы полученных соединений в изопропиловом спирте и исследованы их свойства в качестве бактерицидного средства против сульфатредуцирующих бактерий. Растворы соединений амида бензиламина ПНК и амида анилина ПНК в изопропиловом спирте при концентрации 50 мг/л проявили бактерицидный эффект соответственно равный 90 и 86%, а при концентрации 150 мг/л – 97 и 90% соответственно. Раствор амида бензиламина ПНК в изопропиловом спирте при концентрации 250 мг/л проявляет 100%-ный бактерицидный эффект.              </p><p>Было установлено, что синтезированные амиды обладают высокой бактерицидно-ингибирующей активностью в отношении сульфатредуцирующих бактерий, в связи с чем могут быть использованы в качестве ингибиторов коррозии в нефтяной промышленности.</p></abstract><trans-abstract xml:lang="en"><p>At present, the protection of oil industry equipment from corrosion from a scientific, technical and economic point of view remains one of the most important tasks. Given the relevance of the topic, a bactericide was synthesized to protect oilfield equipment and pipelines from general and microbiological corrosion - an inhibitor of complex action. This paper presents an analysis of the results of scientific research in the field of synthesis, study of properties and search for areas of application of the synthesized amides based on amines (aniline, benzylamine) and natural petroleum acid (NPA). Solutions of the obtained compounds in isopropyl alcohol were prepared and their properties as a bactericidal agent against sulfate-reducing bacteria were studied. Solutions of the compounds of benzylamine amide NPA and aniline amide NPA in isopropyl alcohol at a concentration of 50 mg/l showed a bactericidal effect equal to 90 and 86%, respectively, and at a concentration of 150 mg/l – 97 and 90%, respectively. A solution of benzylamine amide NPA in isopropyl alcohol at a concentration of 250 mg/l exhibits a 100% bactericidal effect.</p><p>               It was found that the synthesized amides have a high bactericidal-inhibiting activity against sulfate-reducing bacteria, and therefore can be used as corrosion inhibitors in the oil industry.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>микробиологическая коррозия</kwd><kwd>бактерицид-ингибитор</kwd><kwd>защитный эффект</kwd><kwd>сульфатредуцирующие бактерии</kwd><kwd>амиды</kwd><kwd>природная нефтяная кислота</kwd></kwd-group><kwd-group xml:lang="en"><kwd>microbiological corrosion</kwd><kwd>inhibitor bactericide</kwd><kwd>protective effect</kwd><kwd>sulfate-reducing bacteria</kwd><kwd>amide</kwd><kwd>natural petroleum acid</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Javaherdashti R.
