IPC: D06M13/188

Abstract: For the treatment of textiles or leather compounds are employed having the following formul  (a) ROR1 in which R is an aromatic or hydroaromatic hydrocarbon radicle containing at least one aliphatic, aliphatic-aromatic or cycloaliphatic radicle having more than three carbon atoms and R1 is an aliphatic radicle carrying at least one acid salt forming group or (b) ROR1X in which R is a hydroaromatic radicle containing at least one aliphatic radicle having more than three carbon atoms, R1 is an aliphatic hydrocarbon radicle containing not more than four carbon atoms and X is COOH or SO3H.  Instead of the said compounds, their salts may be employed.  In examples: (1) the sodium salt of pn-dodecyl-phenoxyethanesulphonic acid is used for washing wool; (2) the sodium salt of p-dodecylphenoxyacetic acid, is used for washing artificial silk fabric; (3) the sodium salt of p-oleylphenoxypropionic acid is used for washing cotton: bleaching agents may be added; (4) the sodium salt of octylxylenyloxypropylethersulphonic, obtained from chloroxypropanesulphonic acid and sodium octyl xylenolate is used for wetting textiles; the free sulphonic acid may be used for carbonizing wool, a similar product is obtained by using sodium isooctylhexahydroxylenolate in place of sodium octylxylenolate; (5) sheep pelt is tanned by means of a mixture of benzylresorcinoloxyethanesulphonic acids; (6) for tanning sole leather a mixture is used of quebracho and cyclohexylnaphthoxyethanesulphonic acid obtainable by condensation of cyclohexanol with a - or b -naphthol and subsequent reaction with chlorethanesulphonic acid; (7) a mercerizing alkali lye contains the sodium salt of p-butylcyclohexyloxyacetic acid or the sodium salt of the sulphuric ester of butylcyclohexylglycol ether; (8) a cleansing powder is formed by mixing sodium carbonate with iso-octylcyclohexyloxyacetic acid; (9) the sodium salt of the phosphoric ester of dibutylcyclohexylglycol ether is used for wetting textile materials.  The use of the products for wetting dyestuff powders and for dispersing oils, fats, waxes and other insoluble substances is mentioned.  The products may be prepared (a) by condensing alkylated, aralkylated or cycloalkylated aromatic hydroxy compounds, e.g. isoamylcresols or isododecylnaphthols, or alkylated or cycloalkylated hydroaromatic alcohols with halogenated fatty acids or halogenated alkylsulphonic acids, (b) by condensing the said hydroxy compounds with halogenhydrins or alkylene oxides and treating with sulphuric or phosphoric acid or other oxygen containing polybasic mineral acid.ALSO:Compounds stated to possess emulsifying properties have the following formul : (1) ROR1 in which R is an aromatic or hydroaromatic hydrocarbon radicle containing at least one aliphatic, aliphatic-aromatic or cycloaliphatic radicle having more than three carbon atoms and R1 is an aliphatic radicle carrying at least one sulphonic, carboxylic or other acid salt-forming group, or (2) ROR1X in which R is a hydroaromatic radicle containing at least one aliphatic radicle having more than three carbon atoms, R1 is an aliphatic hydrocarbon radicle containing not more than four carbon atoms and X is COOH or SO3H.  The emulsification of oils, fats and waxes is referred to.
