Description

Verfahren zur Herstellung von Alkalisalzen von Nitroalkanen und Nitrocycloalkanen Es ist bekannt, daß Nitroalkane und Nitrocycloalkane mit Alkalien Salze bilden, soweit sl>e an, den die Nitrogruppe tragenden Kohlenstoffatomen noch mindestens i Wasserstoffatom enthalten. Die Bildungsgeschwindigkeit .der Salze ist jedoch bei Verwendung wäßriger Alkalilauge .oft sehr gering, so daß die Ausbeute, zum Teil auch infolge von [email protected], mitunter schlecht ist.Process for the preparation of alkali salts of nitroalkanes and nitrocycloalkanes It is known that nitroalkanes and nitrocycloalkanes form salts with alkalis, as far as sl> e, at least the carbon atoms carrying the nitro group i contain hydrogen atom. However, the rate of formation of the salts is Use of aqueous alkali .often very little, so that the yield, in part also as a result of [email protected], is sometimes bad.

Es wurde nun gefunden, daß die Bildung der Alkalisalze viel rascher vor sich geht, wenn man in denNitroalkanen geringe Mengen vonOximen löst und dann die wäßrige Alkalilauge auf diese Lösung einwirken läßt. Die Bildung der Salze erfolgt dann unter Selbsterwärmung augenblicklich und in rahezu quantitativer Ausbeute.It has now been found that the formation of the alkali salts is much more rapid happens when small amounts of oximes are dissolved in the nitroalkanes and then allows the aqueous alkali to act on this solution. The salts are formed then with self-heating instantly and in almost quantitative yield.

Als Oxim kann man grundsätzlich jedes Aldehyd-oder Ketonioxim verwenden; zweckmäßig benutzt man das dem ;angewendeten Nitroalkan bzw. Nitrocycloialkan entsprechende Oxim. Es genügen davon etwa 0,5 bis ioo/o, berechnet .auf -die Nitroverbindung. Die Konzentration der wäßrigen Alkalilauge liegt zweckmäßig über i 5 0'o, vorzugsweise verwendet man höherkonzentrierte z. B. ?5- bis soo,'oige Laugen. Die Alkailisialze der- Nitroalkane bzw. -Nitrocyclo- alkane :sind wertvolle Zwischenprodukte. Die in den Beispielen angegebenen Teile sind Gewic tsteile, _ Bei!spi,el i Man löst in 129 Teilen Nitrocyclohexan i o Teile Cyclohexanonoxim rund versetzt die Lösung unter Kühlung und Rühren mit einer 3o %igen wäßri;gen Lösung von q.o.Teilen Ätznrxtron,. Die Aus- scheidung des Natriumsalzes des Nitrocyclo;hexans beginnt augenblicklich. Das Salz kann abgesaugt und als, solches isoliert oder durch Zusatz von. Wasser in Lösung gebracht werden. Beispiele Arbeitet man wie in Beispzel i und ersetzt die Natronlauge durch eine 5o % ige wäßrige Lösung von, 57 Teilen Ätzkasi, eo erhält man das Kallumsalz des Nitrocyclohexans. In principle, any aldehyde or ketone oxime can be used as the oxime; the oxime corresponding to the nitroalkane or nitrocycloialcan used is expediently used. About 0.5 to 100 per cent, calculated on the nitro compound, are sufficient. The concentration of the aqueous alkali lye is expediently above i 5 0'o, preferably more highly concentrated z. B.? 5- to soo, 'oige lye. The Alkailisialze der- Nitroalkane or -Nitrocyclo- alkanes: are valuable intermediate products. The parts given in the examples are Parts by weight, _ At! Spi, el i 10 parts are dissolved in 129 parts of nitrocyclohexane Cyclohexanone oxime rounds the solution while cooling and stirring with a 3o% aqueous solution of parts of caustic extron. From- separation of the sodium salt of nitrocyclo; hexane starts immediately. The salt can be sucked off and as such, isolated or by the addition of. Water to be brought into solution. Examples If you work as in example i and replace the Sodium hydroxide solution with a 5o% aqueous solution from. 57 parts Ätzkasi, eo you get the Kalumsalz of nitrocyclohexane.
