Description

Verfahren zur Herstellung einer Perverbindung der Essigsäure Es wurde durch das Patent 27a 738 bekannt, aus Acetaldehyd durch trockenen molekularen Sauerstoff -bei tiefen Temperaturen, beispielsweise o°, Persäure zu erhalten. Es tritt aber bei weitgehender Oxydation des angewandten Aldehyds bald ein explosibler Niederschlag auf, wodurch die Durchführung der weiteren Oxydation des Aldehyds unmöglich wird.Process for the production of a per compound of acetic acid It was known from patent 27a 738 to obtain peracid from acetaldehyde by means of dry molecular oxygen at low temperatures, for example 0 °. However, if the aldehyde used is largely oxidized, an explosive precipitate soon occurs, which makes it impossible to carry out further oxidation of the aldehyde.

Es wurde nun gefunden, daß bei diesem Prozeß durch Anwendung von indifferenten organischen Lösungsmitteln für das entstehende Erzeugnis Acetaldehyd ohne Gefahr weitgehend, ja sogar nahezu quantitativ durch molekularen Sauerstoff oder molekularen Sauerstoff enthaltende Gase oxydiert wird und daß sich dabei je z Mol Acetaldehyd und i lIol des molekularen Sauerstoffs zu einem peroxydischen Anlagerung sprodukt verbinden, wie sich aus dem Verbrauch an Acetaldehyd und Sauerstoff sowie durch Titration der gewonnenen Perverbindung ergibt.It has now been found that by using indifferent organic solvents for the resulting product acetaldehyde without danger largely, even almost quantitatively, through molecular oxygen or molecular oxygen Oxygen-containing gases is oxidized and that each z mole of acetaldehyde and i lIol of the molecular oxygen to a peroxidic addition product connect as well as from the consumption of acetaldehyde and oxygen Titration of the obtained per compound results.

Die dabei entstehende Perverbindung hat vermutlich die Formel: Beispiel Einer Lösung von 16 g (= 0,36 Mole) Acetaldehyd in 40 g Eisessig wird nach Zusatz .von o,5/, ihres Gewichts Cobaltacetat bis zur Erschöpfung .der Reaktion trockener Sauerstoff bei o° zugeführt. Die'Aufnahme war beendet, als etwa o,i8 Mole Sauerstoff aufgenommen waren. Durch jodometrische Ti tration wurde eip dem aufgenommenen Sauerstoff nahezu äquivalenter Gehalt an Perverbindung festgestellt. Es ergibt sich aus diesen `'Werten demnach eine nahezu zoo°/oige Anlagerung von z lIol Acetaldehvd an i Mol Sauerstoff. Die so erhaltenen homogenen Lösungen sind in der Kälte gut haltbar. Bei erhöhter Temperatur findet unter starker Wärmeentwicklung Zersetzung statt. .The resulting per compound probably has the formula: EXAMPLE A solution of 16 g (= 0.36 moles) of acetaldehyde in 40 g of glacial acetic acid, after adding 0.5% of its weight of cobalt acetate, is supplied with dry oxygen at 0 ° until the reaction is exhausted. The uptake was finished when about 0.18 moles of oxygen had been taken up. By means of iodometric titration, the per compound content was found to be almost equivalent to the oxygen taken up. According to these values, there is an almost zoo% addition of ten percent acetaldehyde to one mole of oxygen. The homogeneous solutions obtained in this way can be kept well in the cold. At elevated temperatures, decomposition takes place with strong heat generation. .

An Stelle von Eisessig können gegebenenfalls auch andere die 'Reaktion nicht störende indifferente Lösungsmittel, wie beispielsweise Essigester, verwendet werden.Instead of glacial acetic acid, others can also use the reaction non-interfering inert solvents, such as ethyl acetate, are used will.

Als 'Lvl.etallsalzkatalvsatoren sind alle in der Patentschrift 2;273S-angegebenen\letallsalze verwendbar.All metal salts specified in patent specification 2; 273S are listed as metal salt catalysts usable.

Die entstehenden Perverbindungen können als Oxydationsmittel, z. B. zum Bleichen, oder als Polymerisat:onskatalysatoren oder als Ausgangsprodukte für chemische Umsetzungen verwendet werden.The resulting per compounds can be used as oxidizing agents, e.g. B. for bleaching, or as Polymerisat: onskatalysatoren or as starting materials for chemical reactions are used.
