<p>1335257 Mixed copper soaps TENNECO CHEMICALS Inc 17 May 1971 [1 June 1970] 15217/71 Heading C2C [Also in Division C5] Oil-soluble copper mixed soaps of two structurally different saturated or unsaturated aliphatic monocarboxylic acids, for example straight chain,α-, #-,γ-, 8- substituted branched chain acids, are prepared by simultaneously reacting copper or a copper compound with the acid-group containing compounds. Copper acetate, or sulphate may be used and the acidgroup containing compounds may be acids or salts. Many suitable acids are listed and examples describe the use of 2,2-dimethyl pentanoic and 3,5,5-trimethyl heptanoic; 2- ethyl-4 methyl pentanoic and 3,5,5-trimethyl hexanoic; 4-ethyl-5,5-dimethyl hexanoic and 3,5,5-trimethyl hexanoic; n-nonanoic and 3,5,5- trimethyl hexanoic; 2-ethyl-2-hexenoic and 3,5,5-trimethyl hexanoic; 4-ethyl-5,5-dimethyl hexanoic and 2-ethyl hexanoic; n-nonanoic and 2-ethyl hexanoic; 4-methyl pentanoic and nhexanoic; 4-methyl pentanoic and 3,5,5-trimethyl hexanoic; 2-ethyl butanoic and 3,5,5- trimethyl hexanoic acid mixtures in the preparation of the soaps and of mixed copper 3,5,5- trimethyl hexanoate and copper 4-ethyl-5,5- dimethyl hexanoate or copper nonanoate, or copper caprylate/n-nonanoate soaps. The salts may be dissolved in mineral spirits, a non-polar hydrocarbon solvent or a chlorinated non-polar hydrocarbon solvent and mixed with a fuel oil as a soot-remover additive.</p> |
