Abstract
Chlorinated hydrocarbons, e.g. tri- or perchlorethylene, 1:1:2 - trichlorethane, carbon tetrachloride, ethylene dichloride and particularly methyl chloroform, for use in metal degreasing are stabilized by the incorporation of (a) a nitro-aliphatic compound having not more than 3 carbon atoms, preferably nitro-methane, (b) a 1:3-dioxolane which may contain up to two C1-2-alkyl substituents, preferably 1:3-dioxolane itself, and, optionally, (c) an aliphatic carboxylic acid ester, suitably ethyl acetate. Concentrates may be prepared for addition to the solvent in amounts of 1-4% by weight. Such concentrates suitably consist of 10-90% (a) and 90-10% (b) if (c) is absent, or alternatively of 10-80% of each of (a), (b) and (c). Many other suitable compounds (a), (b) and (c) are listed.
