The study of excess molar volumes and related properties for binary mixtures containing benzyl alcohol and 1,3-dichloro-2-propanol with vinyl acetate, ethyl acetate and t-butyl acetate at T = 293.15 to 313.15 K and P = 0.087 MPa

Abstract

The density data for binary mixtures of benzyl alcohol or 1,3-dichloro-2-propanol with vinyl acetate, ethyl acetate and t-butyl acetate were measured at T=(293.15–313.15) K and P=0.087MPa. From these data, the excess molar volumes, partial molar volumes, excess partial molar volumes, partial molar volumes at infinite dilution, apparent molar volumes, thermal expansion coefficients and their excess values are calculated for studied binary systems. The Redlich- Kister equations were fitted to excess molar volumes data. The results show that excess molar volumes for all considered systems are negative and decrease with increasing temperature. The same behavior was observed for excess thermal expansion coefficients. The interactions between molecules in mixtures are discussed and explained based on these experimental data.
