KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Es wurde gefunden, daß die durch Umsetzung des o-Chlorbenzylchlorids mit Sulfit erhältliche ο-Chlorbenzylsulfosäure beim Nitrieren mit einem Moleküläquivalent Salpetersäure eine einheitliche Mononitrochlorbenzylsulfosäure It has been found that the reaction of o-chlorobenzyl chloride with sulfite available ο-chlorobenzylsulfonic acid when nitrating with one molecular equivalent of nitric acid a uniform mononitrochlorobenzylsulfonic acid
(CH2SO3H-Cl-NO2 = 1.2-5) (CH 2 SO 3 H-Cl-NO 2 = 1.2-5)
liefert, und weiter, daß diese neue Säure diesupplies, and further that this new acid the
ίο Eigenschaft besitzt, das Chlor, z. B. beim Erhitzen mit Ammoniak, auszutauschen.ίο has the property that chlorine, e.g. B. at Heating with ammonia, exchange.
Die Bildung jener Nitrochlorbenzylsulfosäure war nicht vorherzusehen, da ebensowohl die Atomgruppe CA2 5O3 H, wie es beim Nitrieren der Benzylsulfosäure unter Bildung von p-Nitrobenzylsulfosäure der Fall ist, als auch das Chlor die Stellung der eintretenden Nitrogruppe beeinflussen konnte. Außerdem wäre auch die Entstehung eines Gemenges von schwer trennbaren isomeren Nitroderivaten möglich gewesen. In einem einzigen anderen Falle war schon die analoge Frage aufgeworfen, ob die Gruppe CH2 SO3 H oder Chlor eine eintretende Nitrogruppe dirigiere, nämlich bei der p-Chlorbenzylsulfosäure. Bei dieser Säure wurde gefunden, daß das Chlor den bestimmenden Einfluß ausübt, und das Verfahren zur Gewinnung der p-Chlor-m-m-dinitrobenzylsulfosäure wurde Gegenstand der Patentschrift 134988.The formation of that nitrochlorobenzylsulfonic acid could not be foreseen, since the atomic group CA 2 5O 3 H, as is the case with the nitration of benzylsulfonic acid with the formation of p-nitrobenzylsulfonic acid, as well as the chlorine could influence the position of the entering nitro group. In addition, the formation of a mixture of difficult to separate isomeric nitro derivatives would have been possible. In a single other case the analogous question was raised whether the group CH 2 SO 3 H or chlorine directs an incoming nitro group, namely p-chlorobenzylsulfonic acid. In the case of this acid, it was found that the chlorine exerts the decisive influence, and the process for obtaining the p-chloro-mm-dinitrobenzylsulfonic acid was the subject of patent 134988.
Eine allgemeine Regel läßt sich aus diesem einzelnen Fall nicht ableiten, und die Feststellung der Tatsache, daß man die genannte Nitrochlorbenzylsulfosäure erhält, daß also auch hier das Chlor den bestimmenden Einfluß ausübt, bedeutet daher gegenüber den verschiedenen Möglichkeiten eines anderen Reaktionsverlaufs eine Erfindung.A general rule cannot be derived from this individual case, and the statement the fact that the nitrochlorobenzylsulfonic acid mentioned is obtained, so that here too chlorine is the determining factor Exerting influence therefore means facing the various possibilities of another Reaction course an invention.
Zur Gewinnung der neuen Säure verfährt man z. B. wie folgt:To obtain the new acid one proceeds z. B. as follows:
16,1 kg o-Chlorbenzylchlorid werden mit einer Lösung von 27 kg Natriumsulfat g'ekocht, bis das Chlorbenzylchlorid verschwunden ist. Aus der erhaltenen Lösung kann durch Kochsalz das Natriumsalz der o-Chlorbenzylsulfosäure abgeschieden und durch Kristallisation aus Alkohol rein gewonnen werden; es bildet weiße glänzende Blättchen.16.1 kg of o-chlorobenzyl chloride are with a solution of 27 kg of sodium sulfate until the chlorobenzyl chloride disappeared is. The sodium salt of o-chlorobenzylsulfonic acid can be obtained from the solution obtained by means of common salt separated and obtained pure by crystallization from alcohol; it forms white, shiny leaflets.
23>8 kg dieses Natriumsalzes werden in 230 kg Schwefelsäuremonohydrat gelöst und bei io° allmählich 23,5 kg eines Gemisches Schwefelsäure (66° Be.) und Salpetersäure (430 Be.) mit einem Gehalt von etwa 28 Prozent HNO3, also einer Menge von 6,6 kg HNO3, d. h. einem Moleküläquivalent SaI-petersäure entsprechend, zugegeben. 2 3> 8 kg of this sodium salt are dissolved in 230 kg of sulfuric acid and io ° gradually 23.5 kg of a mixture of sulfuric acid (66 ° Be.) And nitric acid (43 0 Be.) With a content of about 28 percent of HNO 3, ie an amount of 6.6 kg of HNO 3 , i.e. H. one molecular equivalent of sal-pitric acid was added accordingly.
Durch die Reaktionswärme findet eine beträchtliche Temperatursteigerung statt, der man durch Kühlung begegnet. Indes beeinflußt auch eine Erhöhung der Temperatur bis 500 und mehr den Reaktionsverlauf nicht wesentlich.The heat of reaction causes a considerable increase in temperature, which is countered by cooling. However, an increase in the temperature to 50 ° C. and more does not significantly affect the course of the reaction.
Das Gemenge läßt man 2 bis 3 Stunden stehen und gießt sodann auf Eis. Die Nitrochlorbenzylsulfosäure scheidet sich als Natronsalz großenteils aus; mit Kochsalz erzielt man fast völlige Abscheidung. Es kann aus Wasser umkristallisiert werden und bildet inThe mixture is left to stand for 2 to 3 hours and then poured onto ice. The nitrochlorobenzyl sulfonic acid largely precipitated as sodium salt; almost complete separation is achieved with table salt. It can go out Water are recrystallized and forms in
