DEFINITION

Classification: 585/360

Polycyclic product:

(under subclass 350) Subject matter wherein a hydrocarbon is synthesized having more than one alicyclic moiety.

(1) Note. The rings may be directly connected to each other or may be substituents on an acyclic chain.

(2) Note. Here is found the production of bicyclo or "bridge" compounds, e.g., bicyclo [2,2,1] heptane.
