Verfahren zur )Herstellung eines in der Hauptsache im Kern butylierte ss-Naphtalinsulfosäure enthaltenden Gemisches. Ini Hauptpatent ist ein Verfahren zur Herstellung eines in der Hauptsache im Kern butylierte a-Naphtalinsiilfosäure enthaltenden (Iemisches beschrieben, bei dem Naphtalin zu a-Naphtalinsulfosäure sulfiert und mit normalem primärem Butylalkohol kondensiert wird.
Es wurde nun gefunden, dass man auch ein in der Hauptsache im Kern butylierte f-Naphtalinsulfosäure enthaltendes Gemisch gewinnen kann, wenn man Naphtalin zu ss-Naphtalinsulfosäui-e sulfiert und mit nor malem primärem Butylalkohol kondensiert. Die Sulfierung wird also so geleitet, dass .im wesentlichen die ss-Naphtalinsulfosäui-e ent steht.
Dies kann durch Anwendung höherer Temperaturen als sie für die Gewinnung von a.-Naphtalinsulfosäure erforderlich sind, er reicht werden. Klan kann im vorliegenden Falle das Naphtalin zuerst in P-Stellung sul- fieren und dann mit oder ohne Anwendung von Kondensationsmitteln, wie zum Beispiel konzentrierte Schwefelsäure, mit normalem Butylalkohol behandeln. - Man kann ferner das Naphtalin mit Butylalkohol in Gegenwart von Schwefelsäure derart behandeln,
dass die Sulfierung in P-Stellung und die Kondensation mit dem Butylalkohol gleichzeitig erfolgt. Schliesslich kann man das Naphtalin auch zuerst mit dem Butylalkohol kondensieren und das erhaltene Produkt nachträglich in ss-Stellung sulfieren.
Das butylierte i3-Näphtalirisulfosäure ent haltende Gemisch ist wasserlöslich, reagiert kongosauer und hat ebenso wie das daraus hergestellte Salzgemisch stark netzende Eigen schaften und kann als Mittel zum Netzen, Reinigen, Emulgieren, Suspendieren und Lö sen wasserunlöslicher Stoffe in Wasser, als Zusatz beim Carbonisieren, Färben, Walken, Bleichen etc. von Textilien usw. Verwendung finden.
Beispiel <B>256</B> Teile Naphtalin werden mit der glei chen Menge Schwefelsäure in die ss-Naphtalin- sulfosäure übergeführt. Das Sulfierungsgemisch lässt man auf etwa 120 erkalten, fügt 600 Teile konzentrierte Schwefelsäure hinzu und lä sst unter kräftigem Rühren in dieses Ge misch bei zirka 100 300 Teile Normal- Butylalkohol innerhalb zweier Stunden zu fliessen.
Nach beendetem Eintropfen des Alko hols führt man durch weiteres Erhitzen bei der gleichen Temperatur während mehrerer Stunden die Reaktion zu Ende. Die Reak tionsmasse trennt sich nach dem Abstellen der Rührvorrichtung in zwei Schichten, von denen die obere in der Hauptsache die buty- lierte Sulfosäure enthält.
Durch Neutralisieren des auf diese Art abgetrennten Kondensations- produktes mit Alkali und Eindampfen oder Aussalzen erhält man das Natriumsalz der butylierten NI aphtaliusulfosäure in fester Form. An Stelle der verwendeten 300 Teile rr-Butyl- alkohol können auch kleinere Mengen davon zur Reaktion gebracht werden.
<I>Beispiel 2:</I> 128 Teile Naphtalin, 148 Teile primärer n-Butylalkohol und 400 Teile Schwefelsäure von 6611 B6 werden unter kräftigem Rühren im Verlauf von 4=5 Stunden auf 120' er hit7t. Die Masse wird auf dieser Temperätur gehalten, bis eine Probe in Wasser löslich ist.
Die Aufarbeitung kann in der Weise erfolgen, dass man in der üblichen Weise das Calciumsalz der butylierten Naphtalin- sulfosäure und daraus durch Umsetzung mit Natriumcarbonat das Natriumsalz herstellt, oder dass man in der irn Beispiel 1 beschrie benen Weise das Reaktionsprodukt erkalten lässt, die gebildete obere Schicht abtrennt und aus dieser die freie Säure oder deren Salze gewinnt.
Process for) the preparation of a mixture containing mainly butylated ß-naphthalene sulfonic acid in the core. The main patent describes a process for the preparation of a mainly butylated a-naphthalene silfonic acid containing (in the core) (Iemisches, in which naphthalene is sulfated to a-naphthalene sulfonic acid and condensed with normal primary butyl alcohol.
It has now been found that a mixture containing mainly butylated f-naphthalene sulfonic acid can be obtained if naphthalene is sulfated to form β-naphthalene sulfonic acid and condensed with normal primary butyl alcohol. The sulphonation is thus conducted in such a way that essentially the ss-naphthalenesulphonic acid is formed.
This can be achieved by using temperatures higher than those required for the production of α-naphthalene sulfonic acid. In the present case, Klan can first sulphate the naphthalene in the P position and then treat it with normal butyl alcohol, with or without the use of condensation agents, such as concentrated sulfuric acid. - You can also treat the naphthalene with butyl alcohol in the presence of sulfuric acid in such a way that
that the sulfonation in the P position and the condensation with the butyl alcohol take place simultaneously. Finally, the naphthalene can also first be condensed with the butyl alcohol and the product obtained can subsequently be sulfated in the ss position.
The mixture containing butylated i3-naphthalic sulfonic acid is water-soluble, has a Congo acid reaction and, like the salt mixture produced from it, has strong wetting properties and can be used as a means for wetting, cleaning, emulsifying, suspending and dissolving water-insoluble substances in water, as an additive in carbonizing, Dyeing, fulling, bleaching etc. of textiles etc. find use.
Example <B> 256 </B> parts of naphthalene are converted into β-naphthalene sulfonic acid with the same amount of sulfuric acid. The sulphonation mixture is allowed to cool to about 120, 600 parts of concentrated sulfuric acid are added and, with vigorous stirring, it is allowed to flow into this mixture at about 100-300 parts of normal butyl alcohol within two hours.
After the end of the dropping in of the alcohol, the reaction is brought to an end by further heating at the same temperature for several hours. After the stirrer has been switched off, the reaction mass separates into two layers, of which the upper layer mainly contains the butylated sulfonic acid.
By neutralizing the condensation product separated off in this way with alkali and evaporating or salting out, the sodium salt of the butylated Ni aphthalic sulfonic acid is obtained in solid form. Instead of the 300 parts of r-butyl alcohol used, smaller amounts can also be reacted.
Example 2: 128 parts of naphthalene, 148 parts of primary n-butyl alcohol and 400 parts of sulfuric acid of 6611 B6 are heated to 120 ° in the course of 4 = 5 hours with vigorous stirring. The mass is kept at this temperature until a sample is soluble in water.
Working up can be carried out in such a way that the calcium salt of the butylated naphthalene sulfonic acid is prepared in the usual way and the sodium salt is prepared therefrom by reaction with sodium carbonate, or that the reaction product is allowed to cool in the manner described in Example 1, the upper one formed Layer separates and from this wins the free acid or its salts.
