Description

Weichmachungsmittel für Cellulose und regenerierte Cellulose Unter den zahlreichen Weichmachungsmitteln für Textilien zeichnen sich die Biguanide, die höhere aliphatische Reste als Substituenten tragen, durch hohe Ausgiebigkeit aus. Allerdings neigen sie andererseits zu unerwünschten Ausscheidungen in den Behandlungsbädern, wenn diese als Verunreinigungen Sulfate oder verschiedene andere mit diesen Produkten Fällungen ergebende Anionen enthalten, so daß die Mitverwendung von oft erheblichen Mengen an Schutzkolloiden notwendig ist.Softener for cellulose and regenerated cellulose sub The biguanides stand out among the numerous softeners for textiles, which carry higher aliphatic radicals as substituents, due to high abundance the end. On the other hand, however, they tend to produce undesirable excretions in the treatment baths, if these are sulfates or various other impurities with these products Contain precipitations resulting anions, so that the use of often considerable Amounts of protective colloids is necessary.

Es wurde nun gefunden, daß Biguanide, die solche höhermolekulare aliphatische Reste tragen, deren Kohlenstoffkette durch Heteroatome oder -atomgruppen unterbrochen ist, sehr viel weniger empfindlich gegen fällend wirkende Anionen in den Behandlungsbädern sind; so daß nur ganz geringfügige Zusätze an Schutzkolloiden zu machen sind. Auch die Löslichkeit der neuen Produkte zeigt eine merkliche Verbesserung.It has now been found that biguanides, the such higher molecular weight aliphatic Carry radicals whose carbon chain is interrupted by heteroatoms or groups of atoms is much less sensitive to precipitating anions in the treatment baths are; so that only very minor additions of protective colloids have to be made. Even the solubility of the new products shows a marked improvement.

Man erhält beispielsweise einen vorzüglichen Weichmacher für Kunstseide in pastöser Form, wenn man 6o Teile des Chlorhydrats eines Biguanids der Formel das durch Umsetzung des Monostearinsäurederivats des Diäthylentriamins mit Dicyandiamid und Chlorwasserstoffsäure in bekannter Weise erhältlich ist, mit 7 Teilen eines mit 9 Mol Äthylenoxyd kondensierten Hexylnaphthols als Schutzkolloid und mit 33 Teilen Wasser in der Wärme verrührt. Die erhaltene Paste ist gegen die Fällungsmittel des Leitungswassers (Sulfationen tt. dgl.) erheblich unempfindlicher als eine Mischung, die statt des obenerwähnten Biguanids beispielsweise das Stearylbiguanid enthält.For example, an excellent plasticizer for artificial silk is obtained in pasty form if 6o parts of the hydrochloride of a biguanide of the formula are used which is obtainable in a known manner by reacting the monostearic acid derivative of diethylenetriamine with dicyandiamide and hydrochloric acid, stirred with 7 parts of a hexylnaphthol condensed with 9 moles of ethylene oxide as protective colloid and with 33 parts of water while warming. The paste obtained is considerably less sensitive to the precipitants in tap water (sulfate ions, etc.) than a mixture which contains, for example, stearyl biguanide instead of the above-mentioned biguanide.

Zur Herstellung weiterer Weichmacher mit ähnlichen gutenEigenschaften eignen sich unter anderem auch das Biguanid der Formel das durch Umsetzung des Stearinsäureesters des Äthanolamins mit Dicyandiamid und Chlorwasserstoffsäure erhältlich ist, sowie das Biguanid der Formel das durchUmsetzung des Monooctodecyläthylendiamins mitDicyandiamidundChlorwasserstoffsäure erhältlichist.The biguanide of the formula, inter alia, is also suitable for the production of further plasticizers with similar good properties which is obtainable by reacting the stearic acid ester of ethanolamine with dicyandiamide and hydrochloric acid, as well as the biguanide of the formula which is obtainable by reacting monooctodecylethylenediamine with dicyandiamide and hydrochloric acid.
