KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Nach dem Verfahren der Patentschrift 79577 erhält man durch Einwirkung von Sulfitlösungeq auf Ct1 ct4-Dinitronaphtalin, indem die beiden Nitrogruppen reducirt werden und zugleich drei Sulfogruppen in den Naphtalinkern eintreten, eine Ct1 c^-Naphtylendiamintrisulfosäure, deren Constitution bis jetzt noch nicht mit Sicherheit festgestellt worden ist.According to the process of patent specification 79577, by the action of sulfite solution on Ct 1 ct 4 dinitronaphthalene, in that the two nitro groups are reduced and at the same time three sulfo groups enter the naphthalene nucleus, a Ct 1 c ^ -naphthylenediamine trisulfonic acid is obtained, the constitution of which has not yet been identified Security has been established.
In ganz anderem Sinne verläuft die Reaction, wenn man C1 a4- Dinitronaphtalin -ß2 ß3-disulfosäure, die nach den Angaben der Patentschrift 61174 aus der ßx ß4-NaphtalindisuIfosäure durch Nitriren in schwefelsaurer Lösung dargestellt werden kann, der Behandlung mit Sulfiten unterwirft. Man gelangt dabei in äufserst glatter Weise, zu der Ct1 »^-Amidonaphtol-ß2 ß3-disulfosäure, die, wie sich aus Versuchen ergeben hat, wahrscheinlich im Sinne der in der Patentschrift 67062 beschriebenen Reaction aus intermediär gebildeten Naphtylendiaminderivaten entsteht.The reaction proceeds in a completely different sense if C 1 a 4 -dinitronaphthalene-β 2 β 3 -disulfonic acid, which according to the information in patent 61174 can be prepared from β x β 4 -naphthalene disulfonic acid by nitriding in a sulfuric acid solution, the treatment Subjected with sulfites. One arrives in an extremely smooth manner in the Ct 1 »^ -amidonaphthol-β 2 β 3 -disulfonic acid, which, as has been shown by experiments, probably arises from naphthylenediamine derivatives formed as intermediates in the sense of the reaction described in patent 67062.
Die Ueberführung der U1 c^-Dinitronaphtalinß2 ß3-disulfosäure in die Amidonaphtoldisulfosäure H kann entweder durch längeres Erhitzen mit concentrirten Lösungen von sauren oder neutralen schwefligsauren Salzen in offenen Gefäfsen bewirkt werden, oder durch Erhitzen der genannten Dinitrosäure mit Sulfitlösungen unter Druck bei Temperaturen von 100 bis 150°.The conversion of the U 1 c ^ -Dinitronaphtalinß 2 ß 3 -disulfonic acid into the amidonaphtholdisulfonic acid H can be effected either by prolonged heating with concentrated solutions of acidic or neutral sulphurous acid salts in open vessels, or by heating the named dinitroacid with sulfite solutions under pressure at temperatures from 100 to 150 °.
200 kg Natriumsalz der A1 ct4 - Dinitronaphtalin - ß2 ß3 - disulfosäure werden im verbleiten Druckkessel mit 400 1 Wasser und 1100 kg 40 procentiger Natriumbisulfitlösung unter beständigem Rühren auf 100 bis 1500C. erhitzt, bis in einer herausgenommenen Probe keine Zunahme von Amidonaphtoldisulfosäure mehr zu constatiren ist. Die Masse wird hierauf in ca. 1000 1 Wasser eingetragen, schwach alkalisch gemacht, event, filtrirt und heifs mit Mineralsäuren angesäuert. Die Amidonaphtoldisulfosäure scheidet sich als saures Natronsalz sehr schnell in nahezu weifsen Nädelchen ab. Nach dem Befreien von der Mutterlauge ist die so erhaltene Säure für die Farbstofffabrikation völlig rein genug. Die Eigenschaften derselben stimmen vollkommen mit denen der Amidonaphtoldisulfosäure H überein, wie sie nach den in den Patentschriften 67062 und 69722 angegebenen Verfahren erhalten wird.200 kg sodium salt of A 1 ct 4 - dinitronaphthalene - ß 2 ß 3 - disulfonic acid are in leaded pressure vessel with 400 1 of water and 1100 kg 40 procentiger sodium bisulfite solution with constant stirring at 100 to 150 0 C. heated up in a taken-out sample no increase of amidonaphthol disulfonic acid is more to be found. The mass is then added to about 1000 liters of water, made weakly alkaline, eventually filtered and hot acidified with mineral acids. The amidonaphthol disulfonic acid separates out very quickly as an acid sodium salt in almost white needles. After being freed from the mother liquor, the acid obtained in this way is completely pure enough for dye manufacture. The properties of the same agree perfectly with those of the amidonaphthol disulphonic acid H, as obtained by the processes given in patents 67062 and 69722.
An Stelle des in dem angeführten Beispiel verwendeten Natriumbisulfits können auch andere saure Salze der schwefligen Säure, z. B. Kaliumbisulfit, sowie die sauren schwefligsauren Salze der alkalischen Erden Verwendung finden.Instead of the sodium bisulfite used in the example cited, others can also be used acidic salts of sulphurous acid, e.g. B. Potassium bisulfite, as well as the acidic sulphurous acid salts of the alkaline earths use Find.
100 kg Natriumsalz der Ct1 a4-Dinitronaphtalin - ß2 ß3 - disulfosäure werden im offenen verbleiten Rührwerkskessel mit 200 1 Wasser und 1000 kg Natriumbisulfitlösung von 40 pCt. auf 90 bis ioo° erhitzt, bis völlige Lösung erfolgt ist. Es wird nun Salzsäure im Ueberschufs zugegeben (ca. 500 1 von 19° B.) und noch einige Zeit weiter gerührt. Alsbald beginnt die Abscheidung des sauren Natronsalzes der Amidonaphtoldisulfosäure H, beim Abkühlen scheiden sich noch weitere Mengen derselben aus.100 kg of the sodium salt of Ct 1 a 4 -Dinitronaphtalin - ß 2 ß 3 - disulfonic acid are in an open, leaded stirred tank with 200 l of water and 1000 kg of sodium bisulfite solution of 40 pCt. heated to 90 to 100 ° until complete dissolution takes place. An excess of hydrochloric acid is then added (approx. 500 liters of 19 ° B.) and stirring is continued for some time. The acid sodium salt of the amidonaphthol disulphonic acid H soon begins to separate out, and further quantities of it are separated out on cooling.
Für die Anwendung der neutralen Salze der schwefligen Säure geben wir folgendesFor the application of the neutral salts of sulphurous acid we give the following
100 kg U1 a4 - dinitronaphtalin - ß2 ß3 - disulfosaures Natron werden mit 400 1 Wasser und 400 kg neutralem Natriumsulfit im emaillirten Rührwerkskessel mit Rückflufskühler zum Sieden erhitzt. In kurzer Zeit tritt völlige Lösung ein, zugleich beginnt eine lebhafte Entwickelung von Ammoniak. Das Kochen wird so lange fortgesetzt, bis Ammoniak nur noch spurenweise nachgewiesen werden kann. Es wird sodann heifs mit Salzsäure angesäuert, wobei sich die ax a4- Amidonaphtol-ß2 ßs - disulfosäure als saures Natronsalz abscheidet.100 kg of U 1 a 4 - dinitronaphthalene - ß 2 ß 3 - disulphonic sodium bicarbonate are heated to the boil with 400 l of water and 400 kg of neutral sodium sulphite in an enamelled stirred tank with a reflux condenser. Complete dissolution occurs in a short time, and at the same time a vigorous development of ammonia begins. The boiling continues until only traces of ammonia can be detected. It is then acidified with hot hydrochloric acid, the a x a 4 - amidonaphthol-ß 2 ß s - disulfonic acid separating out as an acidic sodium salt.
