Century Dictionary and Cyclopedia
    • n camphene The generic name of the volatile oils or hydrocarbons having the general formula C10H16, which are isomeric or polymeric with oil of turpentine. Many camphenes exist ready formed in plants, as oil of cloves, bergamot, etc. They are liquid at ordinary temperatures, and are distinguished from one another by their odors, boiling-points, and action on polarized light. They absorb oxygen and convert it into ozone. The name is synonymous with terpene; but by some authorities the latter is made the generic name of all the volatile hydrocarbons having the formula C10H16, while camphene is limited to those terpenes which are solid at ordinary temperatures.
    • n camphene The commercial term for purified oil of turpentine, obtained by distilling the crude oil over quicklime to free it from resin. It gives a brilliant light in lamps having a very strong draft for the prevention of smoke, and was extensively used before the introduction of petroleum.
    • n camphene Dextrocamphene (austracamphene) and levocamphene (terecamphene) are made by heating oil of turpentine, saturated with hydrochloric-acid gas, with alcoholic potash. They are crystalline and melt at 51–52° C. They rotate plane-polarized light in opposite directions. Inactive α-camphene is similar to the preceding, but it is optically inactive and melts at 47° C.
