ABSTRACT

Densities, viscosities, and speeds of sound have been measured for the binary mixtures of 2-methyl-1-propanol {(CH3)2CHCH2OH} with n-hexane (C6H14), n-octane (C8H18), and n-decane (C10H22) over the entire composition range at 298.15 K and at atmospheric pressure. The experimental density (F), viscosity (e) and speed of sound (u) values were used to calculate the excess molar volumes (V E), viscosity deviation (centse), deviation in speed of sound (centsu), isentropic compressibility ( s), and deviation in isentropic compressibility (cents s). The values of VE, centse, centsu and cents s were fitted to the Redlich-Kister polynomial equation and have been used to discuss the presence of significant interactions between alcohols and alkane molecules.
