Patent GB-417394-A (GB)
Title: Improvements in and relating to the manufacture and utilisation of substances suitable for use as penetrating, wetting, emulsifying, dispersing, foaming, cleansing and like agents
Filed: 1933-04-04
Abstract: Products useful as emulsifying and dispersing agents are prepared by condensing aliphatic or alicyclic halogenides containing at least eight carbon atoms and if desired, one or more hydroxy groups, with aromatic amino sulphonic acids free from hydroxy groups.  The halogenides may be prepared by esterification of the corresponding alcohols with hydrogen halides.  As examples of the alcohols, those obtained by reduction of fatty acids or esters, waxes or naphthenic acids or esters are mentioned.  In an example, cetyl chloride is condensed with aniline - 2 : 4 - sodiumdisulphonate, which is obtained by sulphonating sulphanilic acid with oleum.  Instead of the latter component, toluidine disulphonic acids or 1-aminotetrahydronaphthalene - 2 : 4 - disulphonic acid may be used. Specifications 359,001 and 371,822 are referred to.  The Specification as open to inspection under Sect. 91 comprises also the condensation of primary or secondary aliphatic or alicyclic amines, containing at least eight carbon atoms, with reactive aromatic oxy, amino, or oxyaminosulphonic acids preferably in the presence of zinc chloride or sodium bisulphite or with unsulphonated oxy, amino or oxyamino aromatic compounds, in such case the products are sulphonated.  The products may be used in the treatment of raw, spun or woven textiles, e.g. silk or artificial silk or leather or feathers.  Washing, dyeing and carbonizing textiles are mentioned. In further examples: (1) dodecyl chloride is condensed and a -naphthylamine or with p-tolylsulphonica -naphthylamide followed by saponification; with the latter method pure monododecyl-a -naphthyl amine is obtained: (2) 2-naphthol -6 : 8-sodium disulphonate is condensed with dodecylamine in the presence of sodium bisulphite, and the product extracted with alcohol; the 2-naphthol-6 : 8-disulphonate may be replaced by 2-naphthol-3 : 6-sodium disulphonate, 2 : 8-dioxy or 2-amino - 8 - oxynaphthalene - 3 : 6 - sodiumdisulphonate: (3) 2-naphthol-3 : 6 : 8-sodium trisulphonate is condensed with technical octadecylamine or 1-amino-11-oxy-8 : 9-heptadecene. The products may be used for emulsifying solids and insoluble liquids such as waxes, hydrocarbons or animal or vegetable oils. Soaps and sulphonated fats and other wetting and dispersing agents may be used in addition. This subject-matter does not appear in the Specification as accepted.ALSO:Products useful as wetting, penetrating, emulsifying, dispersing, foaming and cleansing agents are prepared by condensing aliphatic or alicyclic halogenides containing at least eight carbon atoms and, if desired, one or more hydroxy groups, with aromatic amino sulphonic acids free from hydroxy groups.
