Использование водотопливных эмульсий на основе жидких углеводородов перспективно для снижения расходов в нефтехимической отрасли, повышения энергосбережения и улучшения экологии путем утилизации отходов ректификации спиртов. Эмульсии не теряют качества при длительном хранении и способны сгорать с высокой тепловой эффективностью. Синтезированные поверхностно-активные реагенты, которые используются в качестве стабилизаторов эмульсий, исследованы методом ИК-спектроскопии. Для них тензиометрическим методом получены изотермы поверхностного натяжения, определены их коллоидно-химические характеристики (критическая концентрация мицеллообразования и соответствующее ей поверхностное натяжение водного раствора, максимальная адсорбция на границе раздела раствор-воздух, свободная энергия адсорбции Гиббса, площадь, приходящаяся на молекулу или ион в поверхностном слое, гидрофильно-липофильный баланс), оценена их эмульгирующая способность. Проведено визуальное микроскопическое наблюдение за структурой полученных эмульсий. Изучена стабильность эмульсий при различных температурах и длительном хранении.</p></abstract><trans-abstract xml:lang="en"><p>The work is devoted to obtaining concentrated water-in-oil emulsions (emulsions of II type, inverse emulsions) with a mixed organic phase (hydrocarbons from diesel fuel and fusel oil), stabilized by surface-active compositions based on carboxylic acids and amine-containing compounds. The use of water-fuel emulsions based on liquid hydrocarbons is promising for reduction of costs in the petrochemical industry, energy saving increase and improvement of the environment by disposing of waste from alcohols distillation. The emulsions do not lose quality during long-term storage and are able to burn with high thermal efficiency. The synthesized surfactants used as emulsion stabilizers were studied by IR spectroscopy. For them, the surface tension isotherms were obtained by the tensiometric method, their colloid-chemical characteristics were determined (the critical concentration of micellization and the corresponding surface tension of an aqueous solution, the maximum adsorption at the solution-air interface, the Gibbs free energy of adsorption, the area per molecule or ion in the surface layer, hydrophilic-lipophilic balance), their emulsifying ability was evaluated. Visual microscopic observation of the structure of the obtained emulsions was carried out. The stability of emulsions at various temperatures and during long-term storage has been studied.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>концентрированные топливные эмульсии</kwd><kwd>дизельное топливо</kwd><kwd>сивушное масло</kwd><kwd>поверхностно-активные вещества</kwd><kwd>изотермы поверхностного натяжения</kwd><kwd>эмульгирование</kwd><kwd>стабильность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>concentrated fuel emulsions</kwd><kwd>diesel fuel</kwd><kwd>fusel oil</kwd><kwd>surfactants</kwd><kwd>surface tension isotherms</kwd><kwd>emulsification</kwd><kwd>stability</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">Ваганов, К.
