IPC: C11D1/88
Filed: 1934-07-20
Abstract: In the treatment of textiles, leather, and other fibrous materials with aqueous liquids, there are added to the latter capillary active substances consisting of a water solubilizing group, an aromatic residue and an aliphatic or cycloaliphatic lipophile residue having at least six carbon atoms, the aromatic residue being bound to the lipophile residue by means of an acid amide group and to the water solubilizing group by means of an amino group, or alternatively the aromatic residue being bound to the water solubilizing group by means of an acid amide group and to the lipophile group by an amino group. Besides being directly attached to the amino or acid amide group the water solubilizing group may be bound thereto by means of an aliphatic residue containing less than six carbon atoms.  The water solubilizing groups are defined as the carboxylic, sulphonic and sulphuric ester groups.  An acidyl group when attached to the amino nitrogen to form a quaternary ammonium group may also function as a water solubilizing group.  The products may be used in wetting, emulsifying, foaming, peptizing, stabilizing, levelling, bleaching, brightening and washing processes.  They may also be used in dyeing with substantive dyestuffs and in preparing water repellant finishes. For the preparation of the wetting &c. agents higher aliphatic or cycloaliphatic primary or secondary amines are condensed, for example, with 1-nitrobenzene 3-sulphohalide or 3-nitrobenzoyl-chloride, the nitro group reduced and a water solubilizing group, as defined above, introduced.  For example, the amino group resulting from the reduction of the nitro group may be treated with alkylating agents to form a quaternary ammonium group or it may be sulphonated by treatment with bisulphite.  Chloracetic acid, b -chlorethanesulphonic acid and alkyl sulphuric acid esters may also be used for introducing water solubilizing groups.  The following products are mentioned: benzene-1-sulphonic-N-dodecylamide-3-sodium aminosulphonate, benzene - 1 - carboxylic - N - octadecylamide - 3-sodium - aminoethanesulphonate, 1 - dodecyl-aminobenzene - 2 - sodiumsulphonate - 4 - sodium acetamidosulphonate, 1 - chlorbenzene - 2 - sulphonic - N - tetradecylamide - 4 - sodium - b  - aminoethylsulphate, 1 - methylbenzene - 4 - sulphonic - N - hexadecylamide - 6 - trimethyl-ammoniumchloride, benzene - 1 - carboxylic-N-octadecylamide - 3 - sodiumaminoacetate, 1-chlorbenzene - 2 - sulphonic - N - tetradecylamide-4-sodiumaminoacetate and naphthalene-1-sulphonic - N - octadecylamide - 4 - sodiumaminoethanesulphonate.  The products may be used in association with solvents, such as hydrocarbons and alcohols, enzymes such as urease and pancreatin, alkali carbonate, trisodium phosphate, alkali pyro, poly, hypo, and metaphosphates, waterglass, alkali metasilicates, borax, sodium sulphate, acid sodium sulphate, hydrogen peroxide and persalts.ALSO:Compounds stated to be useful in dispersing and emulsifying processes comprise a water solubilizing group, an aromatic residue and an aliphatic or cycloaliphatic lipophile residue having at least six carbon atoms, the aromatic residue being bound to the lipophile residue by means of an acid amide group and to the water solubilizing group by means of an amino group, or alternatively the aromatic residue being bound to the water solubilizing group by means of an acid amide group and to the lipophile group by an amino group.  Besides being directly attached to the amino or acid amide group the water solubilizing group may be bound thereto by means of an aliphatic residue containing less than six carbon atoms.  The water solubilizing groups are defined as the carboxylic, sulphonic and sulphuric ester groups.  An acidyl group, when attached to the amino nitrogen to form a quaternary ammonium group may also be used.  The following products are mentioned: benzene-1-sulphonic - N - dodecylamide - 3 - sodium aminosulphonate, benzene-1-carboxylic-N-octadecylamide - 3 - sodium - aminoethanesulphonate, 1-dodecylaminobenzene - 2 - sodiumsulphonate - 4 - sodium acetamidosulphonate, 1-chlorbenzene-2 - sulphonic - N - tetradecylamide - 4 - sodium - b  - aminoethylsulphate, 1 - methylbenzene - 4 - sulphonic - N - hexadecylamide - 6 - trimethylammoniumchloride, benzene - 1 - carboxylic - N - octadecylamide-3-sodiumaminoacetate, 1-chlorbenzene - 2 - sulphonic - N - tetradecylamide - 4 - sodiumaminoacetate and naphthalene - 1 - sulphonic - N - octadecylamide - 4 - sodiumaminoethanesulphonate. The products may be used in association with solvents, such as hydrocarbons and alcohols, enzymes such as urease and pancreatin, alkali carbonate, trisodium phosphate, alkali pyro, poly, hypo, and metaphosphates, water glass, alkali metasilicates, borax, sodium sulphate, acid sodium sulphate, hydrogen peroxide and persalts.
