    Abstract: Free-flowing inorganic ammonium or potassium salts are produced by adding to said salts a mixture of half-esters of sulfuric acid with isomeric nonanols. The salts can be handled (metered, stored, shipped) in an advantageous manner and may be used in a wide range of applications, for example for drying and catalytic purposes and for use as additives to animal feeds.

    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.

    Abstract: Aromatic or pyridine dicarboxylic acids which have two carboxylic groups in the least hindered position and have been obtained by the thermal rearrangement or disproportionation of other carboxylic acids and/or salts, are separated by dissolving the reaction mixture in water or a mixture thereof with low molecular weight water-soluble alcohols or ethers, heating the solution to 80-250 DEG C., acidifying by adding an aromatic monocarboxylic acid or an acid thallium or alkali metal salt (of higher acidity than the corresponding salt of the dicarboxylic acid to be separated) of an aromatic or pyridine dicarboxylic acid, an aromatic polycarboxylic acid, a pyridine carboxylic acid or mixtures thereof to pH 4.1-6.5, the acid salt of the dicarboxylic acid to be separated being completely formed, cooling to 20-30 DEG C., separating the solids and mixing with water to form a slurry which is heated at 105-250 DEG C. at up to 5 atmospheres; acidifying to pH 2.1-4.5 and so that the desired dicarboxylic acid is formed using an aromatic monocarboxylic acid, an aromatic or pyridine di- or poly-carboxylic acid or mixtures thereof or an anhydride of said dicarboxylic acid; cooling to 100-115 DEG C. and separating the crystallized solids. Examples describe the separation of terephthalic acid and pyridine-2, 5-dicarboxylic acid. Naphthalene-2,6-dicarboxylic acid and 4,41-diphenyl dicarboxylic acid are also mentioned. Specification 816,691 is referred to.
