Viscosity, liquid density, and surface tension data of its binary and ternary mixtures with various n-alkanes (n-heptane, n-decane or n-hexadecane) have been evaluated. Its solubility in various hydrocarbon solvents (heptane, dodecane, isomeric mixtures of decahydronapthalene, m- and p-xylene) has been studied. Tetracosane is a linear alkane. Structural characteristics of confined squalane and tetracosane under shear flow conditions have been investigated. Solubility of tetracosane in ethane and ethylene have been investigated.
