The reported mixture properties of metal alkoxide are almost none in spite of their increasing usages. In this work, the excess molar volumes (V-E) were determined from measured densities for six binary systems of titanium butoxide (1) + ethanol (2), titanium butoxide (1) + 1-propanol (2), titanium butoxide (1) + 1-butanol (2), ethanol (1) + 1-propanol (2), 1-propanol (1) + 1-butanol (2) and ethanol (1) + 1-butanol (2) at 298.15 K. The experimental V-E were correlated with the Redlich-Kister polynomial. The partial excess molar volumes at infinite dilution ((V) over bar (E,infinity)(i)) were calculated with fitted binary parameters. Additionally the ternary V-E data at 298.15 K were also predicted for three systems of titanium butoxide (1) + ethanol (2) + 1-propanol (3), titanium butoxide (1) + ethanol (2) + 1-butanol (3) and titanium butoxide (1) + 1-propanol (2) + 1-butanol (3) by using the binary contribution model of Radojkovic with the binary Redlich-Kister parameters.
