Densities and thermal expansions of (water + tetrahydrofuran) mixtures within the temperature range from (274.15 to 333.15) K at atmospheric pressure

摘要: Abstract The mixture {water (1) + tetrahydrofuran (2)} densities have been measured over the whole composition range at temperatures between (274.15 and 333.15 K) atmospheric pressure using vibration type densimeter. Values of excess molar volume isobaric thermal expansion as well apparent/partial volumes (down infinite dilution) for water tetrahydrofuran (THF) calculated. It is shown that formation + THF occurs with decreasing its under all temperatures. Concentration dependences partial are characterized by presence extreme regions. Standard (limiting) increase temperature rising. Increase in both content influence on value same way.
