Data 2005 2005-08-19 Surface tension of decane binary and ternary mixtures with eicosane, docosane and tetracosane A tensiometer operating on the Wilhelmy plate method was employed to measure liquid-vapor interfacial tensions of 3 binary and one ternary mixtures of decane with eicosane, docosane and tetracosane. Binary mixtures n-C10H22 + n-C20H42, n-C10H22 + n-C22H46 and n-C10H22 + n-C24H50 and the ternary n-C10H22 + n-C20H42 + n-C24H50 were measured from 293.15 K (or above the solution melting temperature) up to 343.15 K. An average absolute deviation of 1.3 % was obtained against pure component literature data. No mixture information for the reported systems was found in the literature. Results were modeled with a recently proposed corresponding states model. The average absolute deviation was found to be 1.2 %.
