DEFINITION

Classification: 524/474

Mixing two or more hydrocarbons; or a hydrocarbon other than benzene, toluene, or xylene per se and having numerical limitations other than amount, e.g., included herein are m.p., b.p., viscosity, structure, m.w., etc., or composition or product thereof, DNRM:

(under subclass 1) Subject matter wherein the composition contains two or more designated nonreactive hydrocarbons or wherein the composition contains a single hydrocarbon excluding benzene, toluene, or xylene with numerical limitations other than merely an amount, etc.

(1) Note. Benzene, toluene, or xylene alone are not classified here despite their inherent numerical limitations, i.e., percentage composition. Mixtures, however, of the above ingredients would be proper in subclass 476.

(2) Note. A numerical limitation is one which limits the compound in some way, e.g., refractive index, b.p., m.p., viscosity, molecular weight, aniline number, etc. If the name or structure only are given then the numerical limitation is inherent, e.g., naphthalene possesses 94% carbon or 6% hydrogen, etc.

SEE OR SEARCH THIS CLASS, SUBCLASS:

476, for mixtures of two or more of benzene, toluene, or xylene.

485, for a DNRM which is turpentine, turpentine oil, oil of turpentine, or spirits of turpentine.

498, through 612, for compositions which contain an inert hydrocarbon described only by amount or nominal terms, e.g., naphtha, paraffin, kerosene, etc.
