Abstract
A process for producing an unsaturated cyclic compound, comprising the steps of hydrochlorinating a terpene to produce a hydrochlorinated terpene, and subjecting the hydrochlorinate terpene to elimination of hydrogen chloride to form an unsaturated cyclic compound. The terpene is preferably .alpha.-pinene, .beta.-pinene, camphene or suitable turpentine fraction. The cyclic compounds can be used as monomers and by means of the invention it is thus possible to produce plastics from renewable raw material sources.
