The aim of our present work is to present measurements of the surface tension, density and refractive index for binary mixtures of dibutyl ether with eight 1-alcohols {C₄H₉OC₄H₉+C₃H₇OH,+C₄H₉OH,+C₅H₁₁OH,+C₆H₁₃OH,+C₇H₁₅OH,+C₈H₁₇OH,+C₉H₁₉OH and +C₁₀H₂₁OH} at the temperature of 298.15K and atmospheric pressure. The experimental data are correlated by means of suitable empirical expressions, which relate the surface tension and refractive index of a mixture with its corresponding density. Also, calculated are the surface tension deviations and excess molar volumes from the measured data for all binary mixtures. The results of the study attending to the number of carbon atoms of the 1-alcohol are discussed.
