Experimental results for the density and viscosity of n-hexane+1-hexanol mixtures are reported at temperatures from 303 to 423 K and pressures up to 50 MPa. The binary mixture was studied at three compositions, and measurements on pure 1-hexanol are also reported. The two properties were measured simultaneously using a single vibrating-wire sensor. The present results for density have a precision of +/- 0.07% and an estimated uncertainty of +/- 0.3%. The viscosity measurements have a precision of +/- 1% and an estimated uncertainty of +/- 4%. Representations of the density and viscosity of the mixture as a function of temperature and pressure are proposed using correlation schemes.
