ABSTRACT

The density, viscosity, and thermal conductivity of eight carboxylic acids (pentanoic, hexanoic, heptanoic, octanoic, nonanoic, decanoic, dodecanoic, and tetradecanoic acid) were measured at ambient pressure and temperatures ranging from (290.3 to 473.4) K. The expanded uncertainties (k = 2) of the measurements were estimated to be 0.2 kg*m 3 for the density, 0.04 mPa*s for the viscosity, and 0.003 W*m 1*K 1 for the thermal conductivity (at the 95% level of confidence). The data were correlated using the Rackett equation (in the case of the density) and a modified rough hard-sphere (RHS) model (in the case of the viscosity and thermal conductivity). Generalized forms of the RHS model parameters are presented as functions of the carbon number and temperature.
