STUDY OFDENSITY AND EXCESS MOLAR VOLUME OF BINARY SOLUTIONS 1,2-PROPANEDIOL+DIETHYL KETONE AT VARIOUS TEMPERATURES

Density and excess molar volume of binary mixture of 1, 2-propanediol (1, 2-PD) and diethyl ketone has been investigated at (288.2, 293.2, 298.2, 303.2 and 308.2) K. Studied system was fitted to Redlich-Kister expression which 6 degree of polynomial expansion was obtained. The standard deviation was calculated and reported for (1, 2-PD + diethyl ketone) mixtures.
