DEFINITION

Classification: 585/823

Sorbate is nonhydrocarbon or chemically undetermined component, e.g., "color-former", etc.:

(under subclass 820) Subject matter wherein the constituent removed from the mixture contains an element other than carbon and hydrogen or is elemental carbon or in which the disclosure fails to indicate exactly what elements go to make up the removed constituent.

(1) Note. Where the removed constituent is indicated as being a hydrocarbon, the patent is not classified here, although when such constituent is described as a sensible material (e.g., colored or having an odor) or a precursor of such a material, the patent may be cross-referenced here (subclasses 823+).
