Description

Verfahren zur Herstellung künstlicher Gebilde aus Viscose Das Patent 509 375 betrifft ein Verfahren zur Herstellung künstlicher Gebilde aus Viscose, dessen kennzeichnendes Merkmal darin besteht, daß man der Viscoselösung oder dem F ällbade oder beiden zugleich im Kern alkylierte Naphthalinsulfosäuren oder deren Salze in Mengen bis zu etwa 3 % zusetzt.Process for the production of artificial structures from viscose The patent 509 375 relates to a process for the production of artificial structures from viscose, the characteristic feature of which is that the viscose solution or the precipitation bath or both naphthalene sulfonic acids or their salts, alkylated in the core at the same time, in amounts up to about 3 % added.

Es hat sich nun gezeigt, daß von den hier angegebenen Sulfosäuren sich ganz besonders solche Sulfosäuren des Naphthalins eignen, welche neben den Alkylsubstituenten zwei oder mehrere Sulfogruppen im Kern enthalten. Als derartige Säuren kommen insbesondere die Di- und Trisulfosäuren in Frage, beispielsweise Isopropylnaphthalindisulfosäure. Der besondere Vorteil der Verwendung derartiger Sulfosäuren für den hier vorliegenden Zweck liegt darin, daß sie eine fast unbegrenzte Löslichkeit besitzen. Beispiel Auf je ioo kg eines Fällbades, das aus mit Natriumsulfat ,gesättigter verdünnter Schwefelsäure besteht, setzt man ioo g Isopropylnaphthalindisulfosäure, wie die durch geeignete Kondensation von Beta-Naphthalinsulfosäure mit Isopropylalkohol und entsprechende Reinigung erhalten wird, zu.It has now been shown that of the sulfonic acids specified here those sulfonic acids of naphthalene are particularly suitable, which in addition to the Alkyl substituents contain two or more sulfo groups in the nucleus. As such Acids are particularly suitable di- and trisulfonic acids, for example isopropylnaphthalene disulfonic acid. The particular advantage of using such sulfonic acids for the one present here The purpose is that they have an almost unlimited solubility. example For every 100 kg of a precipitation bath, which is diluted with saturated sodium sulfate Sulfuric acid, one uses 100 g of isopropylnaphthalenedisulfonic acid, such as the by suitable condensation of beta-naphthalenesulfonic acid with isopropyl alcohol and appropriate purification is obtained, too.
