This work reports new density data (180 points) of 1-hexanol at twelve different temperatures between 293.15 and 403.15K (every 10K), and fifteen different pressures from 0.1 to 140MPa (every 10MPa). An Anton Paar vibrating tube densimeter, calibrated with an uncertainty of ±0.5kgm -3 was used to perform these measurements. The experimental density data were fitted with the Tait-like equation with low standard deviations. In addition, the isobaric thermal expansivity and the isothermal compressibility were derived from the Tait-like equation.
