General description

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.
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.

Application

Tetracosane is the suitable solvent used in the synthesis of ZnS nanoparticle. It may be employed as the wax component to study the reduction in pour point of hydrocarbon solvents containing wax crystals on addition of polymer additives.
