A polyalkylene polyamine of formula (in which each of R 1 to R 4 may denote a hydrogen atom, alkyl group having 1-6C or a C 5 or C 6 cycloalkyl group, or any two of the radicals R 1 to R 4 may perm together with the carbon atoms of the aziridine ring a cycloaliphatic ring having 5-12C) or an alkylation or quaternization product of such a polyamine is added to an acid pickling liquor as an inhibitor. The acid may be inorganic e.g. HCl, H 2 SO 4 , H 3 PO 4 , NH 2 SO 3 H, or organic e.g. fermic, citric or tartaric acids. Metals pickled are iron and steel, Cu, Ni, Pb, Zn, Al and their alloys.

    Abstract: 1,130,920. Corrosion inhibitor. BADISCHE ANILIN & SODA FABRIK A. G. Sept. 6, 1966 [Sept.7, 1965], No.39726/66. Heading C7E. A corrosion inhibitor for metal surfaces e.g. pipes or containers of Fe, Cu, Zn, A1 or alloys thereof comprises by weight: 47 to 70 parts of at least one mono/di/cycloalkyl-or alkylen-amide of an unsaturated fatty acid having 14-22 C atoms, 35 to 45 parts of which is monosulphonated, and 1 to 5 parts of at least one unsaturated fatty acid having 14 to 22 C atoms and/or alkali metal or (alkyl) ammonium salt thereof. The alkyl, alkylene or cycloalkyl radicals contain 4 to 12 C atoms, the chain of which may be interrupted by O or NH. Fatty acids specified are linoleic, linolenic, ricinoleic, oleic and palmitic acids. Preferably the same acid/amide is used for all the ingredients of the inhibitor. For example, the inhibitor may consist of monosulphonated oleic di-n-butylamide, oleic di-n-butylamide, oleic acid and sodium oleate. The inhibitor may be used in corrosive aqueous liquids such as mixtures of glycol and water (as antifreeze) or chlorinated hydrocarbons and water (as cleaning agent) in the concentration 0À001-5g/l.

    Abstract: A surfactant mixture comprises (a) 35 to 40 parts by weight of a monoalkylamide, dialkyl-amide, cycloalkylamide or alkylenamide of a monosulphonated and/or monosulphated unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in said radicals being optionally interrupted by -O-or -NH-radicals, (b) 12 to 20 parts by weight of a monoalkylamide, dialkylamide, cycloalkylamide or alkylenamide of an unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in said radicals being optionally interrupted by -O- or -NH- radicals, (c) 2 to 4 parts by weight of an unsaturated fatty acid having 14 to 22 carbon atoms or an alkali-metal or ammonium salt thereof, and (d) 0.05 to 2.5 parts by weight of a completely dissociating inorganic salt, e.g. sodium chloride or sodium sulphate.ALSO:A process for treating textiles comprises contacting them with a textile-treatment liquor containing a surfactant mixture comprising (a) 35 to 40 parts by weight of a monoalkylamide, dialkylamide, cycloalkylamide, or alkylenamide of a monosulphonated and/or monosulphated unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl, or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in said radicals being optionally interrupted by -O- or -NH- radicals, (b) 12 to 20 parts by weight of a monoalkylamide, dialkylamide, cycloalkylamide or alkylenamide of an unsaturated fatty acid having 14 to 22 carbon atoms, at least one of the alkyl or cycloalkyl radicals or the alkylene radical containing 4 to 12 carbon atoms and the chain of carbon atoms in these radicals being optionally interrupted by -O- or -NH- radicals (c) 2 to 4 parts by weight of an unsaturated fatty acid having 14 to 22 carbon atoms or an alkali-metal or ammonium salt thereof, and (d) 0.05 to 2.5 parts by weight of a completely dissociating inorganic salt, e.g. sodium chloride or sodium sulphate. Such liquors are useful as wetting agents for prewetting or reboiling skein yarn, wetting agents for bleaching without preboiling, dyeassistants for substantive dyeing of cotton, dyeassistants for dyeing cotton with sulphur dyes, wetting agents for vats containing levelling agents, wetting agents for bottoming liquors for dyeing cotton with developing dyes, wetting agents for dyeing union goods, and levelling agents in dyeing polyamide fibres with acid dyes.
