Цель работы – установить закономерности влияния нефтерастворимых поверхностно-активных добавок, содержащих полярные функциональные группы различной химической природы, на процессы флокуляции и седиментации модельных нефтяных дисперсных систем. Методы исследования – ИК-спектроскопия, метод турбидиметрического титрования и дисперсионнный анализ. В результате установлено, что при использовании отечественной поверхностно-активной добавки, содержащей одновременноамино- и фосфатные группы в цепи, наблюдается синергетический эффект за счет суммарного действия этих функциональных групп, который проявляется в замедлении процессов флокуляции (эффективность действия составляет 108%) и седиментации модельных нефтяных дисперсий, что подтверждается снижением в 13 раз показателей скорости и константы седиментации и уменьшением в 1,6–3,2 раза размера ассоциатов смолисто-асфальтеновых веществ, что приводит к повышению агрегативной и кинетической устойчивости коллоидной системы. Показано, что данная добавка является эффективным ингибитором флокуляции и диспергирующим агентом для нефтяных дисперсных систем, что позволяет рекомендовать ее для практического применения вместо импортных дорогостоящих аналогов.</p></abstract><trans-abstract xml:lang="en"><p>There is a trend in the world for production growth of hardly recoverable heavy oils and bitumen with high content of resin-asphaltene substances that precipitate when aggregated, causing stability loss of oil dispersies. The goal of this work is to establish regularities for the effect of oil soluble surfactant additives containing the polar functional groups of different chemical nature on the processes of flocculation and sedimentation of model oil dispersions. Methods emplоyed are infrared spectroscopy, turbidimetric titration and dispersion analysis. It has been found that the domestically produced surfactant additive containing both amino and phosphate groups in the chain causes synergistic effect, due to simultaneous action of these functional groups, that slows down flocculation processes (efficiency is 108%) and sedimentation of model oil dispersions, which is confirmed by 13 times reduction of rates and sedimentation constants and 1.6–3.2 times decrease of associate size for resin-asphaltene substances. This results in the increase of aggregative and kinetic stability of the colloidal system. It has been shown that the additive is an effective flocculation inhibitor and dispersing agent for oil dispersion systems, that can be recommended for practical application as a substitute for expensive imported analogues.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>флокуляция</kwd><kwd>седиментация</kwd><kwd>нефтяные дисперсные системы</kwd><kwd>поверхностно-активные вещества</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flocculation</kwd><kwd>sedimentation</kwd><kwd>oil dispersive systems</kwd><kwd>surfactants</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">Сафиева, Д.
