.~> Inorganic reactant other than sulfur containing {3}
DEFINITION
Classification: 252/182.11
COMPOSITIONS CONTAINING A SINGLE CHEMICAL REACTANT OR PLURALNONINTERACTIVE CHEMICAL REACTANTS; I.E., NOT VIS-A-VIS:
(under the class definition) Composition s containing a single reactant or plural reactants under the class definition specialized or designed for use in subsequent reactions with other materials, but not with each other.
(1) Note. The addition of a material which serves a dual purpose, i.e., reactant plus diluent, solvent, plasticizer, etc., will be classified as a reactant; if the patent is silent as to its function than it will be classified as a nonreactive material.
(2) Note. The relationship between a subclass and subclasses indented thereunder is such that reference is always to the same reactant, unless the indented subclass begins with "With or Contains" in which case they may refer to any reactant.
(3) Note. A composition containing a reactant metal, element or compound stabilized with a specified material, or a process of making such a composition, is nonetheless classified accordingly with the metal, element or compound
classes.
(4) Note. Whenever possible, full recognition should be given to the term "catalyst" in describing a given substance even though from prior art the substance is known to behave as a reactant. Thus, triethanolamine can react with polyisocyanates to form polyurethanes; however, if it stated that triethanolamine functions as a catalyst in aiding the condensation of polyols with polyisocyanate, then it is classified in the catalyst class and not as a reactant. Similarly, a composition specified to function as an accelerating agent will be classified in the catalyst class. Vulcanizing a curing compositions are considered proper herein unless it is clear that their function is strictly catalytic. Peroxide compositions, per se, will be considered as catalysts, and therefore, proper for the catalyst class.
(5) Note. To be classified in this or the indented subclasses a patent must not recite a claim drawn to a composition containing a solid synthetic polymer. Where a patent sets forth claims which are drawn to species that may or may not be synthetic polymers as per disclosure, or where a patent contains only generic claims and the disclosure, or where a patent contains only generic claims and the disclosure sets forth species which are appropriate as synthetic polymers and species which are appropriate as synthetic polymers and species which are not, the patent is placed here as an original with the species which are appropriate as synthetic polymers and species which are nonresinous and cross-referenced to the appropriate polymer classes. Polymers are limited to synthetic organic polymers and excludes inorganic polymer, natural polymers, e.g., starch, cellulose, collegen, wool, etc.
(6) Note. A composition which contains (1) potentially reactable ingredients to be polymerized and (2) all or the necessary reactants to form a desired synthetic resin or (3) those reactants which are potentially reactable at room temperature or that require merely heat and/or pressure or moisture when reactant contains Si-C, Si-H, -N=C=X, (X is chalcogen) or is a liquid polysulfide is classified in appropriate polymer classes. (7) Note. See Lines With Other Classes and Within This Class, in the main class definition of this class (252) for a hierarchical listing of composition classes.

2+, for gas generating compositions for extinguishing fires.
60+, for gas generating compositions specialized for use in forthfloation separation processes.
181.1+, for getter and gas or vapor generating compositions for electric lamps, electric space discharge devices and other evacuated or gas or vapor filled containers.
183.11, for the additon of a stabilizer or inhibitor to a composition to prevent the interaction between two or more reactants, such that the reactants can interact on removal of the stablizer or inhibitor.

149, Explosive and Thermic Compositions or Charges, appropriate subclasses for gas generating compositions which undergo a chemical change at a very rapid rate, or rate approaching instantaneous reaction, resulting in the production of usable force as in blasting, fire arms, jet propulsion, filling automotive passenger gas-bags, etc.
502, Catalyst, Solid Sorbent, or Support Therefor: Product or Process of Making, for catalysts and reaction accelerating agents, per se.
516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art; including those instances when a composition would otherwise be proper for this subclass (182.11) and its indented subclasses.
521, Synthetic Resins or Natural Rubbers, 50+, for compositions containing all the required reactants or polymer derived thereof plus a foam generating composition (blowing agent).
