Description
Verfahren zur Herstellung von Gemischen aus Kobaltnitrosocarbonyl und Kobaltnitrosyl bzw. von Kobaltnitrosyl allein Das Hauptpatent 566 448 betrifft ein Verfahren zur Herstellung von Kobaltnitrosocarbonyl, das dadurch gekennzeichnet ist, daß man Kohlenoxyd oder solches enthaltende Gase in Gegenwart von Stickoxyden auf Kobalt oder kobalthaltige Materialien einwirken läßt. Gemäß Beispiel i dieses Patentes gewinnt man das Kobaltnitrosocarbonyl als rote Flüssigkeit durch Einwirkung von etwa 5 11, Stickoxyd enthaltendem Kohlenoxyd auf fein verteiltes metallisches Kobalt bei 6o bis 70'. Process for the production of mixtures of cobalt nitrosocarbonyl and cobalt nitrosyl or of cobalt nitrosyl alone. The main patent 566 448 relates to a process for the production of cobalt nitrosocarbonyl, which is characterized in that carbon oxide or gases containing carbon are allowed to act on cobalt or cobalt-containing materials in the presence of nitrogen oxides. According to example i of this patent, cobalt nitrosocarbonyl is obtained as a red liquid by the action of about 5 11 carbon monoxide containing nitrogen oxide on finely divided metallic cobalt at 60 to 70 °.
Es wurde nun gefunden, daß man bei Verwendung kohlenoxydhaltiger Gasgemische, die mehr als 5 0jo Stickoxyde enthalten, neben Kobaltnitrosocarbonyl zunehmende Mengen Kobaltnitrosyl und schließlich letzteres allein erhält. Beispielsweise erhält man bereits praktisch ausschließlich Kobaltnitrosyl mit einem Gemisch aus etwa 15 % Stickoxyden und 85 °J, Kohlenoxyd.It has now been found that when using gas mixtures containing carbon dioxide, which contain more than 5 0jo nitric oxides, in addition to cobalt nitrosocarbonyl increasing Amounts of cobalt nitrosyl and ultimately the latter alone. For example, receives one already practically exclusively cobalt nitrosyl with a mixture of about 15 % Nitrogen oxides and 85 ° J, carbon oxide.
Das Kobaltnitrosyl bildet tiefdunkelbraune Kristalle, die, äußerlich betrachtet, dem Kaliumpermanganat ähneln und im Vakuum bei etwa 6o ° unzersetzt sublimiert werden können. Die Zusammensetzung entspricht der Formel CO(NO)g. Das gebildete Nitrosyl kann für sich allein oder im Gemisch mit Kobaltnitrosocarbonyl thermisch oder in sonst geeigneter Weise zersetzt bzw. umgesetzt ,verden und auf diese Weise zur Gewinnung von reinem Kobalt oder Kobaltsalzen Anwendung finden. Beispiel i Ein 81/, Kobalt enthaltendes technisches Abfallmaterial wird bei 300' 14 Stunden lang mit strömendem Wasserstoff reduziert. Das reduzierte Material wird auf i5o° abgekühlt und dann bei gewöhnlichem Druck mit Kohlenoxyd behandelt, das io °l, Stickoxyd enthält. Es werden dadurch pro Tag bis zu 2o10 des vorhandenen Kobalts in Kobaltnitrosyl übergeführt, das etwa 150/0 Kobaltnitrosocarbonyl enthält. Beispiel e Ein 7% Kobalt enthaltendes technisches Abfallmaterial wird .in Stückform getrocknet und bei 30o° 12 Stunden lang mit strömendem Wasserstoff reduziert. Das reduzierte Material wird auf 170' abgekühlt und bei gewöhnlichem Druck mit Kohlenoxyd behandelt, das 6 °lo Stickoxyd enthält. Es werden pro Tag. bis zu 15 °4 des vorhandenen Kobalts zu annhernd gleichen Teilen in Kobaltnitrosyl und Kobaltnitrosocarbonyl übergeführt.The cobalt nitrosyl forms deep dark brown crystals, which, viewed from the outside, resemble potassium permanganate and can be sublimed without decomposition in a vacuum at about 60 °. The composition corresponds to the formula CO (NO) g. The nitrosyl formed can, by itself or in a mixture with cobalt nitrosocarbonyl, thermally or in any other suitable manner, decompose or reacted, and in this way be used for the production of pure cobalt or cobalt salts. Example i An industrial waste material containing cobalt is reduced at 300 ° for 14 hours with flowing hydrogen. The reduced material is cooled to 150 ° and then treated at ordinary pressure with carbon dioxide, which contains 100% of nitrogen oxide. As a result, up to 2o10 of the cobalt present is converted into cobalt nitrosyl per day, which contains about 150/0 cobalt nitrosocarbonyl. Example e A technical waste material containing 7% cobalt is dried in bar form and reduced with flowing hydrogen at 30o ° for 12 hours. The reduced material is cooled to 170 ° and treated at ordinary pressure with carbon monoxide containing 6 ° lo nitrogen oxide. It will be a day. Up to 1 5 ° 4 of the cobalt present is converted in approximately equal parts into cobalt nitrosyl and cobalt nitrosocarbonyl.
