DEFINITION

Classification: 524/476

Two or more hydrocarbons:

(under subclass 474) Subject matter wherein the composition contains at least two designated nonreactive hydrocarbons, e.g., naphthalene and toluene, etc.

(1) Note. Naturally occurring mixtures per se, e.g., naphthenics, raffinates, aromatics, white spirit, naphthas, paraffins, xylenes, kerosenes, paraffin wax, high and low melting waxes, turpentine, etc., are classified only when there is some limitation, e.g., 75% ortho and 25% para xylene mixture, a paraffin oil containing 20% aromatic hydrocarbon, etc.
