Description
Verfahren zur Herstellung von N-Nitroso-N-alkylhydroxylaminen bzw. N-Nitroso-N-cycloalkylhydroxylaminen, ihren Salzen und Komplexverbindungen N-Nitrosoderivate von N-monosubstituiertenHydroxylaminen lassen sich in der Weise herstellen, daß man auf metallorganische Verbindungen, wie Phenylmagnesiumbromid oder Triäthylaluminium, Stickstoffmonoxyd oder Nitrosylchlorid einwirken läßt (vgl. J. S a n d und F. S i n g e r, Liebigs Ann. d. Chemie, Bd. 329 [1903], S. 190; E. B. Baker und H. H. Sisler, Journ. Amen Chem. Soc., Bd. 75 [1953], S. 5193; E. Müller und H. Metzger, Chem. Ber., Bd. 89 [1956], S. 396). Dieses Verfahren ist für eine technische Herstellung der genannten Verbindungen ungeeignet.Process for the production of N-nitroso-N-alkylhydroxylamines or N-nitroso-N-cycloalkylhydroxylamines, their salts and complex compounds N-nitroso derivatives of N-monosubstituted hydroxylamines can be prepared in such a way that on organometallic compounds such as phenylmagnesium bromide or triethylaluminum, Allow nitrogen monoxide or nitrosyl chloride to act (cf. J. S a n d and F. S i n g e r, Liebigs Ann. d. Chemie, Vol. 329 [1903], p. 190; E. B. Baker and H. H. Sisler, Journ. Amen Chem. Soc. 75: 5193 [1953]; E. Müller and H. Metzger, Chem. Ber., 89, 396 [1956]). This process is for an industrial production of the compounds mentioned unsuitable.
Man hat die gleichen Verbindungen auch bereits in der Weise hergestellt, daß man auf N-monosubstituierte Hydroxylamine nitrosierende Mittel einwirken ließ; dabei wurde es als für den Erfolg wesentlich angesehen, daß man eine Lösung von Natriumnitrit möglichst rasch in eine gekühlte mineralsaure Lösung des N-monosubstituierten Hydroxylamins einlaufen ließ (vgl. E. Bamberger, Ber. deutsch. Chem. Ges., Bd. 27 [1890], S. 1552; 0. Piloty und O. Ruf f, ebenda, Bd. 30 [1897], S. 1660). Dabei sind die Ausbeuten an den gewünschten N-Nitrosoderivaten im allgemeinen unbefriedigend; sie übersteigen im Falle der N-Alkyl- und N-Cycloall#:ylhydraxylamine nicht 400/, der Theorie. Diese schlechten Ausbeuten wurden mit der Zersetzlichkeit der Verbindungen, besonders in saurem Medium, erklärt.The same connections have already been made in the same way that nitrosating agents were allowed to act on N-monosubstituted hydroxylamines; it was considered essential for success that one could find a solution from Sodium nitrite as quickly as possible in a cooled mineral acid solution of the N-monosubstituted Hydroxylamine was allowed to run in (cf. E. Bamberger, Ber. Deutsch. Chem. Ges., Vol. 27 [1890], p. 1552; 0. Piloty and O. Ruf f, ibid., Vol. 30 [1897], p. 1660). Included the yields of the desired N-nitroso derivatives are generally unsatisfactory; in the case of N-alkyl- and N-cycloall #: ylhydraxylamine they do not exceed 400 /, the theory. These poor yields were due to the degradability of the compounds, especially in acidic medium, explained.
Es wurde nun gefunden, daß man N-Nitroso-N-alkyl-bzw. -cycloalkylhydro-xylamine und ihre Salze und Komplexverbindungen in sehr guten Ausbeuten und in reiner Form erhält, wenn man zu einer schwach sauren wäßrigen Lösung eines N-Alkyl- bzw. N-Cycloalkylhydroxylamins unter Kühlen eine Lösung von Alkalinitrit derart zufließen läßt, daß sich keine freie salpetrige Säure bildet, und die erhaltenen Nitrosoverbindungen gewünschtenfalls gleichzeitig oder nachträglich mit etwa äquivalenten Mengen einer Lösung eines wasserlöslichen Salzes eines Metalls der IL bis IV. Hauptgruppe oder der I. bis VIII. Nebengruppe des Periodensystems umsetzt.It has now been found that N-nitroso-N-alkyl or. -cycloalkylhydro-xylamines and their salts and complex compounds in very good yields and in pure form obtained when one adds to a weakly acidic aqueous solution of an N-alkyl- or N-cycloalkylhydroxylamine A solution of alkali metal nitrite can flow in with cooling in such a way that none forms free nitrous acid, and the nitroso compounds obtained, if desired at the same time or afterwards with approximately equivalent amounts of a solution of a water-soluble one Salt of a metal of the IL to IV. Main group or the I to VIII. Subgroup of the periodic table.
Geeignete Ausgangsstoffe sind z. B. das N-Methyl-, N-Isopropyl-, N-Heptyl-(4)-, N-Butyl-(2)-, N-Cyclohexyl-, N-Cycloheptyl- und N-Cyclooktylhydroxylamin.Suitable starting materials are, for. B. the N-methyl-, N-isopropyl-, N-heptyl- (4) -, N-butyl- (2) -, N-cyclohexyl-, N-cycloheptyl- and N-cyclooctylhydroxylamine.
Die N-Nitrosoverbindungen, die in Abwesenheit der Metallsalze in sehr reiner Form und in fast quantitativer Ausbeute ausfallen, können gewünschtenfalls durch Absaugen oder Abschleudern als solche gewonnen werden. Sie bilden z. B. mit Ammoniak oder Aminen wasserlösliche Salze, aus denen man durch doppelte Umsetzung mit wasserlöslichen Salzen der II. bis IV. Hauptgruppe oder der I. bis VIII. Nebengruppe des Periodensystems der Metalle die Metallsalze bzw.. Komplexverbindungen herstellen kann. Letztere erhält man unmittelbar, wenn man ein wasserlösliches Salz eines der genannten Metalle, z. B. Kupfersulfat, Zinkchlorid, Nickelnitrat oder Kobaltacetat, zur schwach sauren Lösung des N-Alky1- oder N-Cycloalkylhydroxylamins zusetzt und dann allmählich die Alkalinitritlösung einfließen läßt. Erforderlichenfalls sorgt man z. B. durch gleichzeitige Zugabe von Alkalihydroxyd oder -carbonatlösung oder von Pufferlösungen dafür, daß sich der für die Fällung des Metallsalzes bzw. Metallkomplexes günstigste pn-Wert einstellt, den man leicht durch Vorversuche ermitteln kann.The N-nitroso compounds, which in the absence of metal salts in very much pure form and in almost quantitative yield can, if desired obtained as such by suction or centrifugation. You form z. B. with Ammonia or amines water-soluble salts, from which one can double conversion with water-soluble salts of main group II to IV or subgroup I to VIII of the Periodic Table of Metals to produce the metal salts or complex compounds can. The latter can be obtained immediately if one uses a water-soluble salt of one of the metals mentioned, e.g. B. copper sulfate, zinc chloride, nickel nitrate or cobalt acetate, to the weakly acidic solution of the N-Alky1- or N-Cycloalkylhydroxylamin and then gradually let the alkali metal nitrite solution flow in. If necessary, provides one z. B. by simultaneous addition of alkali hydroxide or carbonate solution or of buffer solutions for the precipitation of the metal salt or metal complex sets the most favorable pn value, which can easily be determined by preliminary tests.
Die N-Nitroso-N-alkyl- und -cycloalkylhydroxylamine und ihre Salze und Metallkomplexe sind wertvolle Zwischenprodukte und Hilfsstoffe für die Lack- und Kunststoffindustrie.The N-nitroso-N-alkyl- and -cycloalkylhydroxylamines and their salts and metal complexes are valuable intermediate products and auxiliaries for paint and plastics industry.
Die in den Beispielen genannten Teile sind Gewichtsteile. Beispiel 1 Zu einer Lösung von 115 Teilen N-Cyclohexyl-hydroxylamin in 600 Teilen Zn-Salzsäure läßt man unter gutem Rühren bei - 5. bis - 5'C eine wäßrige Lösung von 69 Teilen Natriumnitrat so langsam zufließen, daß Kaliumjodid-Stärkepapier erst am Schluß der Nitritzugabe gefärbt wird. Der dabei sich abscheidende, praktisch farblose Niederschlag wird abgesaugt, mit Eiswasser gewaschen und an der Luft getrocknet. Man erhält 129 Teile (= 90 °/a der Theorie) N-Nitroso-N-cyclohexylhydroxylamin vom Schmp. 42 bis 43°C. Durch Ausäthern der Mutterlauge erhält man eine weitere, geringe Menge der gleichen Verbindung.The parts mentioned in the examples are parts by weight. Example 1 To a solution of 115 parts of N-cyclohexyl-hydroxylamine in 600 parts of Zn-hydrochloric acid is allowed with thorough stirring at - 5 to - 5'C an aqueous solution of 69 parts of sodium nitrate accrue so slowly that potassium iodide-starch paper only at At the end of the addition of nitride it is colored.
