cyclododecane

Cyclododecane is a saturated cycloalkane with the chemical formula C12H24. The molecule consists of a twelve-membered carbon ring, giving it high symmetry and a nonpolar character. It is not found in nature and is produced synthetically for use in research and industry.

Physical properties and structure: At room temperature cyclododecane is a colorless, waxy solid. Its melting point is around 58–60°C, and it has a high boiling point near 260°C. It is poorly soluble in water and soluble in nonpolar organic solvents such as hexane. The compound is relatively chemically inert, with low reactivity toward typical acids and bases.

Production and handling: Cyclododecane is prepared by synthetic cyclization or ring-closing reactions of appropriate hydrocarbon precursors. In practical use, it is handled as a solid with a slow tendency to soften or melt under heat, and it is stored away from ignition sources because it is flammable.

Uses and applications: In forensic conservation and some museum practices, cyclododecane is employed as a temporary protective coating because it slowly evaporates at ambient conditions, leaving treated surfaces uncovered over time. In analytical chemistry and organic synthesis, it serves as a reference hydrocarbon or nonpolar solvent component and as a model guest molecule in host–guest chemistry studies.

Safety: Cyclododecane is a flammable hydrocarbon. Vapors can form explosive mixtures with air, and prolonged exposure may irritate the skin or eyes. It should be stored in a well-ventilated area away from heat and flames and handled with appropriate protective equipment.
