摘要: Densities, , have been measured for the binary systems of tetrahydrofuran + n-butanol, sec-butanol and tert-butanol in whole range composition between 303.15 323.15 K at an interval 5 K. From excess molar volumes, apparent molal thermal expansivities, are estimated. For all systems, values fitted to polynomial equations, whereas, Redlich-Kister equations. Here, positive but n-butanol system, small latter two large.
