Patent GB-610038-A (GB)
Title: Manufacture and use of reaction products of organic compounds containing sulphonic acid groups with quaternary ammonium compounds
IPC: D06P5/13
Filed: 1945-07-03
Abstract: New compounds are prepared by treating quaternary ammonium compounds containing an aliphatic, cycloaliphatic or araliphatic residue containing 10-18 carbon atoms with a synthetic tanning agent containing an aromatic nucleus and at least one sulphonic acid group. They may be used as textile assistants (see Group IV (c)).  In examples: (1) phenyloctadecyl-dimethyl ammonium metho-sulphate is reacted with the liquid tanning agent obtained by condensing cresol sulphonic acid, urea and formaldehyde as described in Specification 456,741; (2) trimethyl amino acetic acid N-dodecyl amide metho-sulphate is reacted with a tanning agent obtained from dioxy diphenyl sulphone, naphthalene sulphonic acid and formaldehyde as described in Specification 375,160, with or without sulphite lye; (4) trimethyl amino acetic acid N-dodecyl anilide metho-sulphate is reacted with a tanning agent of the type described in Specification 506,493.  In like manner, other products may be obtained from dodecyl oxymethyl-pyridinium chloride and a tanning agent of the type described in Specification 425,527; from octadecyl pyridinium bromide and "Tannigan A" and from trimethyl - (a  - heptadecyl benzyl) ammonium metho-sulphate, trimethyl-octadecenyl ammonium metho-sulphate or trimethyl amino acetic acid N-octadecyl anilide and a tanning agent of the kind described in Specification 456,741.  Many other suitable quaternary ammonium compounds and tanning agents are referred to.  The Specification as open to inspection under Sect. 91 includes the reaction of any organic compound containing a sulphonic group and having tanning properties with a quaternary compound having an aliphatic or cycloaliphatic residue of high molecular weight. This subject-matter does not appear in the Specification as accepted.ALSO:New compounds are prepared by treating quaternary ammonium compounds containing an aliphatic, cycloaliphatic or araliphatic residue having 10-18 carbon atoms with a synthetic tanning agent containing an aromatic nucleus and at least one sulphonic acid group.  They may be produced in substance and isolated, for example, by salting-out or evaporation or may be previously produced in the textile baths by means of which they are to be applied.  They are soluble in water or alkali solutions and may be used as textile assistants (see Group IV (c)).  In examples: (1) phenyl-octadecyl-dimethyl ammonium metho-sulphate is reacted with the liquid tanning agent obtained by condensation of cresol sulphonic acid, urea and formaldehyde, as described in Specification 456,741, or (2) with a condensation product of naphthalene sulphonic acid and formaldehyde; (3) trimethylamino acetic acid N-dodecylamide methosulphate is reacted with a tanning agent, obtained from dioxydiphenyl sulphone, naphthalene sulphonic acid and formaldehyde as described in Specification 375,160, with or without sulphite lye; (4) trimethylaminoacetic acid N-dodecyl anilide metho-sulphate is reacted with a tanning agent of the type described in Specification 506,493.  Other products may be obtained in like manner from dodecyloxymethyl pyridinium chloride and a tanning agent of the type described in Specification 425,527, from octadecyl-pyridinium bromide and Tannigan "A", and from trimethyl-(a -heptadecylbenzyl)ammonium metho-sulphate, trimethyl-octadecenyl ammonium metho-sulphate or trimethylamino-acetic acid-N-octadecyl-anilide and a tanning agent of the kind described in Specification 456,741.  Other specified starting materials are trimethyl-cetyl-ammonium bromide, diisopropylbenzyl-trimethyl ammonium bromide, dodecyl-oxymethyl-pyridinium chloride, dodecyl-pyridinium sulphate, a -undecyl-N-benzyl-trimethyl ammonium methosulphate, 4-octadecylamino-phenyl trimethyl ammonium metho sulphate and octadecylaminoethyl trimethyl ammonium metho-sulphate and the condensation products of formaldehyde and phenol-or naphthol-sulphonic acids, formaldehyde and partially or completely sulphonated doxy-diaryl sulphones and aromatic sulphonic acids, urea and phenol-sulphonic acids and formaldehyde, and the products known as Tannigan S, V, extra A and extra C.  The Specification as open to inspection under Sect. 91 includes the preparation of textile assistants by reaction of any organic compound containing a sulphonic acid group and having tanning properties with a quaternary ammonium compound having an aliphatic or cycloaliphatic residue of high molecular weight.  This subject-matter does not appear in the Specification as accepted.ALSO:New textile assistants for use in levelling or finishing, in stripping dyeings of vat-dyestuffs and in dyeing with vat-, acid- or direct-dyestuffs are the compounds prepared by treating quaternary ammonium compounds containing an aliphatic, cycloaliphatic or araliphatic residue having 10-18 carbon atoms with a synthetic tanning agent containing an aromatic nucleus and at least one sulphonic acid group (see Group IV (b)).  The Specification as open to inspection under Sect. 91 describes the assistants as those prepared by reacting any organic compound containing a sulphonic group and having tanning properties with a quaternary ammonium compound having an aliphatic or cycloaliphatic residue of high molecular weight.  This subject-matter does not appear in the Specification as accepted.
