N2 - Experimental data of dynamic viscosity (η) and density (ρ) of pure alcohols (1-butanol, 1-pentanol, 1-heptanol, 1-octanol and 1-nonanol) are presented in the temperature range from (293.15 to 323.15) K and pressures up to 30 MPa. The data were obtained simultaneously, a capillary tube viscometer was used to measure the dynamic viscosity coupled with a vibrating tube densimeter where density is obtained. The expanded uncertainties (k = 2) of the reported data were estimated considering the impurities of the samples and are 0.90% and 0.10% for the dynamic viscosity and density measurements, respectively. Also, the dynamic viscosity and density data obtained in this study were modeled successfully as a function of pressure and temperature, through empirical equations previously published in literature. Finally, isothermal compressibilities and thermal isobaric expansivities were obtained using the density data set obtained.
