Method and device for separating high-purity sabinene from cinnamomum longepaniculatum oil

The invention discloses a method and device for separating high-purity sabinene from cinnamomum longepaniculatum oil. The method comprises the following steps: refining cinnamomum longepaniculatum branches and leaves to obtain cinnamomum longepaniculatum oil, preheating the cinnamomum longepaniculatum oil, putting the preheated cinnamomum longepaniculatum oil into a rectifying tower, enabling the cinnamomum longepaniculatum oil to be in countercurrent contact with steam generated by a tower kettle to obtain crude sabinene liquid, processing the crude sabinene liquid by using a reflux ratio controller according to a set reflux ratio to obtain liquid to be refined, sending the liquid to be refined into a molecular distiller for secondary separation to obtain light-phase gas and heavy-phase liquid, injecting the heavy-phase liquid into a rectifying tower, and allowing the light-phase gas to pass through a second condenser so as to obtain sabinene liquid with a content larger than 85%. The device comprises the re
