Определены критическая концентрация мицеллообразования, поверхностная активность и адсорбция на межфазной границе, минимальная площадь, занимаемая молекулой амина. Показано, что критическая концентрация мицеллобразования снижается, поверхностная активность и адсорбция на границе раздела раствор ПАВ/воздух увеличивается при переходе от алифатического к алициклическому и ароматическому амину и в присутствии низкомолекулярного электролита.</p></abstract><trans-abstract xml:lang="en"><p>The surface properties of amines with different molecular structures, including an aliphatic amine (alkylammonium chloride), an alicyclic amine (alkylmorpholine), and an aromatic amine (benzethonium chloride), were investigated in aqueous and sodium chloride solutions. The critical micelle concentration, surface activity, adsorption at the solution/air interface, and the minimum area occupied by an amine molecule at the interface were determined. It was shown that the critical micelle concentration decreases, while surface activity and adsorption at the surfactant solution/air interface increase when transitioning from aliphatic to alicyclic and aromatic amines, and also in the presence of a low-molecular-weight electrolyte.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>поверхностно-активные вещества</kwd><kwd>амины</kwd><kwd>поверхностное натяжение</kwd><kwd>поверхностная актив­ность</kwd><kwd>критическая концентрация мицеллообразования</kwd><kwd>электролит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surfactants</kwd><kwd>amines</kwd><kwd>surface tension</kwd><kwd>surface activity</kwd><kwd>critical micelle concentration</kwd><kwd>electrolyte</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">Поверхностно-активные вещества и полимеры в водных растворах / К.
