Description
Verfahren zur Herstellung einer wasserlöslichen Verbindung der aromatischen Reihe. Gegenstand des vorliegenden Zusatzpaten tes ist ein Verfahren zur Darstellung des Natronsalzes der ms-Hexadecyldesoxybenzoin- sulfonsäure, das man durch Sulfonierung des ms-Hexadecyldesoxybenzoins und Neutrali sierung der entstandenen Sulfonsäure erhält.
Die neue Verbindung wird als helles Pulver erhalten, das in Wasser sehr leicht löslich ist und dessen Lösungen Cellulosere- generaten und nativen Cellulosen vorzüg liche Weichheit verleihen; wertvoll ist dabei die Eigenschaft der neuen Verbindung, Farb- stofflösungen unbeeinflusst zu lassen, so dass ihre Anwendung im Färbebad erfolgen kann.
<I>Beispiel:</I> In 40 Teile Monohydrat werden unter Rühren bei<B>100</B> C 20 Teile ms-Hexadecyl- desoxybenzoin eingetragen, darauf langsam bei<B>-50</B> C 40 Teile Oleum (66 o/oig) zuge- tropft. Nach vierstündigem Rühren unter <B>100</B> C erweist sich eine in Wasser gegebene Probe vollständig löslich. Sobald dies der Fall ist, wird die Reaktionsmasse auf Eis gegossen, die ausgeschiedene freie Sulfonsäure abgetrennt und durch Zusatz von Natronlauge neutralisiert.
Durch Eindampfen gewinnt man das Natronsalz als helles Pulver, das in Wasser sehr leicht löslich ist und dessen Lösungen Celluloseregeneraten und nativen Cellulosen vorzügliche Weichheit verleihen.
Process for the preparation of a water-soluble aromatic series compound. The subject of the present additional patent is a process for the preparation of the sodium salt of ms-hexadecyldeoxybenzoin sulfonic acid, which is obtained by sulfonating the ms-hexadecyldeoxybenzoin and neutralizing the sulfonic acid formed.
The new compound is obtained as a light-colored powder which is very easily soluble in water and whose solutions give cellulose regenerates and native celluloses excellent softness; What is valuable here is the property of the new compound of leaving dye solutions unaffected so that they can be used in the dye bath.
<I> Example: </I> 20 parts of ms-hexadecyldeoxybenzoin are added to 40 parts of monohydrate with stirring at <B> 100 </B> C, and then slowly at <B> -50 </B> C 40 parts Oleum (66%) was added dropwise. After stirring for four hours at <B> 100 </B> C, a sample placed in water proves to be completely soluble. As soon as this is the case, the reaction mass is poured onto ice, the free sulfonic acid which has separated out is separated off and neutralized by adding sodium hydroxide solution.
The sodium salt is obtained as a light powder by evaporation, which is very easily soluble in water and whose solutions give regenerated cellulose and native celluloses excellent softness.
