Description
Stwierdzono, ze kwasy sulfoaminowe drugorzedowych amin alifatycznych, któ¬ rych jedna grupa alkylowa zawiera co naj¬ mniej trzy i co najwyzej osiem atomów we¬ gla, moga byc dodawane do lugów mercery- zacyjnych jako doskonale srodki zwilza¬ jace.Sa one na ogól latwo rozpuszczalne w lugach merceryzacyjnych i moga byc zasto¬ sowane do emulgowania substancji trudno rozpuszczalnych w lugach stezonych. Takie kwasy sulfoaminowe, które w stezonych lu¬ gach sa niedostatecznie rozpuszczalne, mo¬ ga byc przeprowadzone do roztworu przez dodanie znanych srodków rozpraszajacych.W porównaniu z amidami kwasu dwu- tio weglowe go, stosowanymi zgodnie z pa¬ tentem niemieckim Nr 597 646 do tego sa¬ mego celu, kwasy sulfoaminowe maja te wyzszosc, ze sa nieczule na dzialanie soli metali i na stykanie sie z metalami, np. z miedzia.Opisane w literaturze patentowej kwasy sulfoaminowe o duzej czasteczce, zawiera¬ jace grupy alkylowe o lancuchu zlozonym z wiecej anizeli osmiu atomów wegla, ustepu¬ ja znacznie srodkom wedlug wynalazku o mniejszym ciezarze czasteczkowym pod wzgledem dzialaitiia zwilzajacego przy za¬ stosowaniu ich do lugu merceryzacyjnego.Kwasy sulfoaminowe wymienionych a- miin drugorzedowych otrzymuje sie z latwo-scia sposobami znanymi przez dzialanie trójtlenku siarki, kwasu chlorosulfonowego, amidoisulfonowego i)t. d. na aminy.Przyklad L 'Doi lugtf merceryzacyjnego o 30°Be dodaje sie 0,3%, w obliczeniu na wage lugu, soli sodowej kwasu dwu - n - - propylol - sulfoaminowego.

PLIt has been found that the sulfamic acids of secondary aliphatic amines, one alkyl group of which contains at least three and at most eight carbon atoms, can be added to mercerization liquors as excellent wetting agents. They are generally easy to use. soluble in mercerization liquors and can be used to emulsify sparingly soluble substances in concentrated liquors. Such sulfamic acids, which are insufficiently soluble in the concentrated slurry, can be brought into solution by the addition of known dispersants. Compared to the dihydric acid amides used in accordance with German Patent No. 597,646 for this For the same purpose, sulfoamino acids have the advantage that they are insensitive to the action of metal salts and contact with metals, e.g. copper. Described in the patent literature, sulfamic acids with large molecules, containing alkyl groups with a chain consisting of more than than eight carbon atoms, it is much inferior to the agents according to the invention with a lower molecular weight in terms of wetting action when applied to mercerization slurry. chlorosulfonate, amide sulfonic acid i) m. d. on amines. Example L 'Dilution of mercerization at 30 ° Be added 0.3%, calculated on the weight of the liquor, of the sodium salt of di - n - propylol - sulfamic acid. The raw cotton becomes wet with such a slurry almost immediately! By adding organic solvents, the wetting or shrinking action of the slurry can be strengthened even more. Example II. 15 parts by weight of diisobutylsulfamine dihydrate sodium are dissolved in 100 parts by weight of technical xylenol and a further 7 parts by weight of crude xylol are added to the solution. 5 g of this mixture per 1 liter of mercerization slurry is sufficient to achieve a very rapid shrinkage of raw cotton.
