The dependence of molar volume on concentration Vm = f(p,x)T is described by a polynomial equation with relative deviation 0.5%. A characteristic feature for all of three studied mixtures is that an insignificant growth of the partial molar volumes of water and a decrease of the partial molar volumes of the alcohols take place with increasing alcohol concentration. Water – hydrocarbon mixtures in the critical state have a similar character of the dependence of partial molar volume on concentration.</p></abstract><trans-abstract xml:lang="ru"><p>В работе для расчета парциальных молярных объемов использованы собственные экспери-ментальные p,Vm,T,x-зависимости (x – концентрация спирта в мольных долях) систем вода – алифатический спирт (метанол, этанол, н-пропанол) состава x: 0, 0.2, 0.5, 0.8, 1 в сверх-критической области, описанные полиномиальным уравнением состояния вида со средней относительной погрешностью 0.5%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>концентрация</kwd><kwd>парциальный молярный объем</kwd><kwd>избыточный молярный объем</kwd><kwd>сверхкритическая область</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composition</kwd><kwd>partial molar volume</kwd><kwd>excess molar volume</kwd><kwd>supercritical state</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">Карапетъянц М.Х.
