DEFINITION

Classification: 570/102

With preservative or stabilizer:

(under subclass 101) Halogen containing compound containing an additional ingredient intended to prevent or decrease chemical or physical change of the compound.

(1) Note. A preserved compound claimed as having a utility provided for in the composition classes is classified with the composition.However, a mere recital of the destabilizing effect or medium guarded against, e.g., "in contact with aluminum", etc., will not prevent placement of a patent in this or indented subclasses.

SEE OR SEARCH THIS CLASS, SUBCLASS:

177+, 211, 238+, or 262+, for a process of increasing the stability of the appropriate compound by purification.

264, for a process of treating a compound of this class to increase stability which does not involve purification or the use of an added agent which remains as part of the composition.

134, Cleaning and Liquid Contact With Solids, for a process of cleaning using a halogenated solvent, particularly 31, for vapor degreasing.

252, Compositions,
