DEFINITION

Classification: 585/355

Camphene or ten-C monocyclic from polycyclic, e.g., terpene isomerization, etc.:

(under subclass 353) Subject matter wherein the feedstock to the reaction is a material having more than one ring and the product is camphene (Fig. 1) or a hydrocarbon having one alicyclic ring and ten carbon atoms. [figure] [caption]FIGURE 1.

(1) Note. Because most dictionaries do not carry a list of C10 terpenes, the following list, although incomplete, is presented as a guide to such materials:

Carvestrene: racemic mixture of sylvestrene optical isomers (no illustration). Dipentene: racemic mixture of limonene optical isomers.
