DEFINITION

Classification: 106/123.11

CELLULOSE LIBERATION WASTE LIQUOR, SOLID, OR REACTION PRODUCT THEREOF CONTAINING (E.G., BLACK LIQUOR, SULFITE YEAST LIQUOR, NEUTRALIZED SULFITE LIQUOR, ETC.):

(under the class definition) Compositions which contain a waste product from sulfur paper making process or the chemical modification of such waste product.

(1) Note. This subclass and indented subclasses provide for all treatments of waste cellulose liberation residues or liquor for which there is no provision elsewhere.

(2) Note. The expression "organic compound" in this and indented subclasses corresponds to the class 260 class definition, i.e., compounds containing carbon, which are further characterized by the presence in a molecule thereof of (a) two carbon atoms bonded together, (b) one atom of carbon bonded to at least one atom of hydrogen or halogen, or (c) one atom of carbon bonded to at least one atom of nitrogen by a single or double bond, with the proviso that HCN, CN-CN, HNCO, HNCS, cyanamide, cyanogen halides, fulminic acid, metal carbides, and graphite are excluded from being organic compounds.
