Cyclododecane is an organic compound with the chemical formula (CH2)12. It is a waxy white solid that is soluble in nonpolar organic solvents.
It is a precursor to laurolactam, a precursor to the polymer Nylon-12.
Cyclododecane is also an intermediate in production of flame retardants, detergents, and other chemicals.
Cyclododecane is also used as a volatile binding medium, a temporary binder for sealing and conservation of friable and structurally weak materials, e.g. during excavation and transport of archaeological objects and in art restoration, e.g. to protect water-sensitive parts during cleaning. Due to its relatively slow evaporation in comparison with other volatile binding mediums the layer can last for several weeks. Very pure material has to be used so it does not leave any residue. Cyclododecane can be applied in molten state or dissolved in a nonpolar organic solvent. Other volatile binding mediums in use are camphene, tricyclene and with some limits menthol.[2]
Cyclododecane is persistent in the environment, as it does not biodegrade easily. Cyclododecane is lipophilic, usually present in the environment as adsorbed on the surface of soil particles. It has the potential to bioaccumulate. Concentrations above 1 mg/L are toxic to aquatic life.
