Cyclooctane and cyclononane are used as starting materials
for organic synthesis. The major use of cyclododecane is as
an intermediate for the production of chemicals used to make
polyamides, polyesters, synthetic lubricating oils, and nylon
12; it is also used as a high-purity solvent. An emulsion of
cyclododecane can be used to emulsify pesticides. It is also
used as a mothproofing agent.
