Description
Verfahren zum Reinigen von Sulfitsprit durch Abscheidung von darin enthaltenen Carbonylverbindungen Zusatz zum Patent 944011 Gegenstand des Hauptpatentes 944011 ist ein Verfahren zur Abscheidung von Carbonylverbindungen durch Kationenaustauscher, welches dadurch gekennzeichnet ist, daß die Lösungen, die die Carbonylverbindungen enthalten, mit Kationenaustauschern behandelt werden, die durch Beladung mit stickstoffhaltigen Verbindungen mit Reaktionsvermögen für Carbonylgruppen gegen Aldehyde und Ketone sorptionsfähig gemacht wurden. Process for purifying sulphite fuel by deposition therein contained carbonyl compounds Addition to patent 944011 Subject of the main patent 944011 is a process for the separation of carbonyl compounds by means of cation exchangers, which is characterized in that the solutions containing the carbonyl compounds contain, are treated with cation exchangers, which by loading with nitrogen-containing Compounds with reactivity for carbonyl groups against aldehydes and ketones have been made capable of sorption.
In weiterer Ausbildung des Verfahrens wurde nun gefunden, daß sich dieses Verfahren vorteilhaft zum Aldehydabscheiden aus Sulfitsprit eignet. In a further development of the process it has now been found that this process is advantageously suitable for separating aldehydes from sulphite fuel.
Zum Reinigen von Sulfit-Rohsprit eignen sich dabei besonders Austauschermassen, die auf der Basis einer Polystyrol- bzw. einer polymeren Phenolsulfonsäure aufgebaut sind. Die Austauscher werden im Säulenverfahren in bekannter Weise mit 700 ccm einer 1 n-Salzsäure regeneriert und anschließend mit 1800 ccm Wasser bis zur Säurefreiheit des Kolonnenablaufes gewaschen. Nach Aufgeben von 600 ccm Hydroxylammoniumchloridlösung mit einer Durchlaufgeschwindigkeit von 3 bis 5 ccm/Aqin. und nachträgliches Waschen mit etwa 250 ccm Wasser bei gleicher Durchlaufgeschwindigkeit wird technischer 960/oiger Sulfltspri t mit einem Aldehydgehalt von durchschnittlich 215 mg/l aufgegeben. Zu diesem Zeitpunkt betragen die Säulenabmessungen 27 490 bzw. Exchange masses are particularly suitable for cleaning raw sulphite spirits, built on the basis of a polystyrene or a polymeric phenol sulfonic acid are. The exchangers are in the column process in a known manner with 700 ccm a 1 N hydrochloric acid is regenerated and then with 1800 ccm of water until it is acid free washed the column effluent. After giving up 600 ccm of hydroxylammonium chloride solution with a throughput speed of 3 to 5 ccm / aqin. and subsequent washing with about 250 ccm of water at the same throughput speed, it becomes more technical 960 / oiger Sulfltspri t with an average aldehyde content of 215 mg / l. to At this point in time the column dimensions are 27 490 resp.
27 580 mm. Durch die Alkoholzugabe verringern sich aber die Höhen um etwa 60 bzw. 40mm. Bei einer Durchlaufgeschwindigkeit von etwa 3 bis 4 ml/.Min. können etwa 15 bzw. 38 1 Sulfitsprit vollkommen vom Aldehyd befreit werden. Die Aldehvdbestimmung wird dabei nach der standardisierten Bestimmungsmethode des Bundesmonopolamtes ausgeführt.27 580 mm. However, the addition of alcohol reduces the heights by about 60 or 40mm. With a throughput speed of about 3 to 4 ml / min. 15 or 38 l of sulphite alcohol can be completely freed from the aldehyde. the Aldehyde determination is based on the standardized Determination method of the Federal Monopoly Office executed.
