Abstract
Досліджено температурну залежність розчинності 1-[2-метил-1-(4-метилфеніл)-5-феніл1H-пірол-3-іл]етанону в метилацетаті, етилацетаті, ацетонітрилі, н-пропанолі та ізо-пропанолі. Розраховано ентальпію та ентропію розчинення. За результатами диференційно-термічного аналізу визначено термодинамічні параметри процесу плавлення та температуру плавлення. Проведено перерахунок ентальпії та ентропії плавлення до 298,15 К. Розраховано величини ентальпії та ентропії змішування 1-[2-метил-1-(4-метилфеніл)-5-феніл-1H-пірол-3іл]етанону з метилацетатом, етилацетатом, ацетонітрилом, н-пропанолом та ізо-пропанолом.
The temperature dependence of the solubility of 1-[2-methyl-1-(4-methylphenyl)-5-phenyl-1H-pyrrol-3-yl]ethanone in methyl acetate, ethyl acetate, acetonitrile, propan-1-ol and propan-2-ol has been investigated. The enthalpy and entropy of dissolution were calculated. The thermodynamic parameters of the melting process and the melting point were determined based on the results of differential thermal analysis. The enthalpy and entropy of melting were recalculated to 298.15 K. The enthalpy and entropy of mixing 1-[2-methyl-1-(4-methylphenyl)-5-phenyl-1H-pyrrol-3-yl]ethanone with methyl acetate, ethyl acetate, acetonitrile, propan-1-ol, and propan-2-ol were calculated.
