C14C24

C14C24 is a designation used in petrochemical and refinery contexts to indicate the hydrocarbon fraction containing molecules with 14 to 24 carbon atoms. It is not a single chemical compound but a range that helps describe feeds, products, and process streams.

Composition typically includes linear and branched alkanes from tetradecane (C14H30) to tetracosane (C24H50), along with cycloalkanes and small fractions of arenes. The exact mix depends on the crude source and the refining process; light-end and heavy-end cut sizes influence the accuracy of labeling.

Physical properties follow carbon-number trends: higher average carbon content generally yields higher boiling points, greater density, and higher viscosity. The C14–C24 fraction usually exhibits a broad boiling range and relatively low volatility compared with lighter refinery streams.

Applications include serving as a distillation cut in the manufacture of lubricants, waxes, and heavier fuel blends, as well as a feedstock for upgrading processes. In analytical contexts, C14C24 helps classify products in inventories, product specifications, and life-cycle assessments.

Safety and environmental considerations are typical of hydrocarbon liquids: they are flammable, may form hazardous vapors, and can contribute to air and soil pollution if released. Handling requires standard industrial hygiene practices, spill containment, and adherence to relevant regulations.
