Получены истинные значения термодинамических параметров в результате устранения методических погрешностей дифференциальной сканирующей калориметрии. Выявлена гетерогенная природа твердофазных переходов и применена теория размытых фазовых переходов для количественного анализа их пиков теплоемкости. Термодинамические параметры и рассчитанные объемы нанозародышей показали зависимости от симметрии молекул н-алканов.</p></abstract><trans-abstract xml:lang="en"><p>The features of phase transitions in the homologous series of n-alkanes have been studied. The true values of the thermodynamic parameters were obtained as a result of eliminating the DSC experimental error. The heterogeneous nature of solid-solid phase transitions is revealed. The theory of diffuse phase transitions is applied for the analysis of the heat capacity peaks of such transitions. The dependences of thermodynamic parameters and calculated volumes of nanonuclei on the symmetry of n-alkane molecules are obtained.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>н-алканы</kwd><kwd>молекулярные кристаллы</kwd><kwd>фазовые переходы</kwd><kwd>дифференциальная сканирующая калориметрия</kwd><kwd>эффект четности.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>n-alkanes</kwd><kwd>molecular crystals</kwd><kwd>phase transitions</kwd><kwd>differential scanning calorimetry</kwd><kwd>parity effect.</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">Lazaro A., Peñalosa C., Solé A. et al.
