Description

Verfahren zum Reinigen von organischen sauerstoffhaltigen Erzeugnissen, die durch Anlagerung von Kohlenoxyd und Wasserstoff hergestellt worden sind Bei der Umsetzung von Olefinen mit Kohlenoxyd und Wasserstoff, vorzugsweise unter dem Einfluß von Eisen-, Nickel- oder Kobaltkatalysatoren, mit dem Ziel, Aldehyde, Ketone oder deren Hydrierungserzeugnisse herzustellen, erhält man häufig flüssige sauerstoffhaltige Erzeugnisse, die den Katalysator oder daraus entstandene Verbindungen, insbesondere also Eisen-, Nickel- oder Kobaltverbindungen, in molekularer oder kolloid gelöster Form enthalten. Diese Bestandteile sind bei der weiteren Verarbeitung der Erzeugnisse häufig hinderlich. Auch gehen auf diese Weise, vor allem im fortlaufenden Betrieb, wesentliche Mengen der Katalysatormetalle verloren. Es wurde nun gefunden, daß man die bei der Anlagerung von Kohlenoxyd und Wasserstoff an Olefine erhaltenen sauerstoffhaltigen Verbindungen vollständig oder teilweise von den darin gelösten Metallen oder Metallverbindungen in einfacher Weise befreien kann, wenn man die Erzeugnisse in flüssiger Phase in Gegenwart von Füllkörpern oder großoberflächigen Stoffen, die keine Reduktionskatalysatoren sind, bei erhöhter Temperatur und unter erhöhtem Druck mit Wasserstoff behandelt.Process for cleaning organic products containing oxygen, which have been produced by the addition of carbon monoxide and hydrogen the reaction of olefins with carbon dioxide and hydrogen, preferably below the Influence of iron, nickel or cobalt catalysts, with the aim of aldehydes, ketones or to produce their hydrogenation products, liquid oxygen-containing products are often obtained Products containing the catalyst or compounds formed therefrom, in particular i.e. iron, nickel or cobalt compounds, in molecular or colloid form Form included. These components are used in the further processing of the products often a hindrance. Also go in this way, especially in ongoing operation, substantial amounts of the catalyst metals are lost. It has now been found that one those containing oxygen obtained from the addition of carbon monoxide and hydrogen to olefins Compounds wholly or partially from the metals or metal compounds dissolved therein can be liberated in a simple manner if the products are in the liquid phase Presence of packing or large-area materials that do not have reduction catalysts are treated with hydrogen at elevated temperature and pressure.

Am zweckmäßigsten schließt man diese Behandlung unmittelbar an die Herstellung der Erzeugnisse in einem mit großoberflächigen Stoffen, wie aktiver Kohle, Kieselgur, Bimsstein, Kieselgel oder einfachen Füllkörpern beschickten Raum an. Dies kann diskontinuierlich in Druckkesseln oder auch fortlaufend, z. B. im Riesel- oder Sumpfverfahren, geschehen.It is best to follow this treatment immediately after the Manufacture of products in one with large surface substances, such as active Money, Diatomaceous earth, pumice stone, silica gel or simple packings filled the room. This can be done discontinuously in pressure vessels or continuously, e.g. B. in the trickle or swamp processes.

Die geeignete Behandlungstemperatur hängt von der Art des Behandlungsgutes, der gelösten Metalle oder der Metallverbindungen ab. Im allgemeinen arbeitet man zwischen 5o und 25o°, zweckmäßig zwischen ioo und 15o°; dies entspricht auch im allgemeinen der Temperatur, mit der die sauerstoffhaltigen Erzeugnisse das Umsetzungsgefäß ihrer Herstellung verlassen. Der Wasserstoffdruck beträgt zweckmäßig mindestens 2o Atm., man kann auch bei 5o, 8o oder Zoo Atm. Druck oder darüber arbeiten.The suitable treatment temperature depends on the type of material to be treated, the dissolved metals or metal compounds. Generally one works between 5o and 25o °, expediently between 100 and 15o °; this also corresponds to the generally the temperature at which the oxygen-containing products enter the reaction vessel leave their manufacture. The hydrogen pressure is expediently at least 2o Atm., You can also use 5o, 8o or Zoo Atm. Pressure or work over it.

BeidieserBehandlungwerden dieMetallverbindungen zu den Metallen reduziert und schlagen sich fein verteilt auf den Füllköpern oder den großoberflächigen Stoffen nieder. Man kann dann, wenn eine größere Menge der sauerstoffhaltigen Erzeugnisse nachbehandelt worden ist, die mit Metallen angereicherten Körper auswechseln und das Metall gewinnen.During this treatment, the metal compounds are reduced to the metals and beat up finely distributed on the filling bodies or the large-surface fabrics low. One can then when a larger amount of the oxygen-containing products has been post-treated, replace the body enriched with metals and win the metal.

Die nach dem vorliegenden Verfahren behandelten Flüssigkeiten sind ganz oder teilweise metallfrei, wodurch die Abtrennung und Gewinnung der sauerstoffhaltigen Erzeugnisse besonders erleichtert wird. Die sauerstoffhaltigen Verbindungen können bei der Behandlung mehr oder weniger hydriert werden. Es ist durch geeignete Abstimmung der Verfahrensbedingungen leicht zu erreichen, daß eine vollständige Hydrierung der sauerstoffhaltigen Verbindungen unterbleibt. Beispiel i Eine aus Aldehyden, Ketonen, Alkoholen und Kohlenwasserstoffen bestehende Flüssigkeit (Carbonylzahl 158), die durch Einwirkung von Kohlenoxyd und Wasserstoff auf ein Kohlenwasserstoffgemisch (Kp. = 5o bis ioo°, Olefmgehalt 45 %) bei 13o° und unter no Atm. Druck in Gegenwart von metallischem Kobalt erhalten worden ist; enthält 0,15 Gewichtsprozent Kobalt in gelöster Form. Man läßt sie mit einer Geschwindigkeit von io 1 in der Stunde durch ein mit Bimsstein beschicktes senkrechtes Hochdruckrohr von 251 Inhalt bei ioo° rieseln, während man gleichzeitig Wasserstoff von 25 Atm. Druck aufpreßt. Die ablaufende Flüssigkeit (Carbonylzahl 15o) bleibt im Gegensatz zur zulaufenden selbst nach längerem Stehen vollkommen klar, sie enthält nur noch o,o2 Gewichtsprozent Kobalt. Beispiel 2 Eine aus Aldehyden, Ketonen, Alkoholen und Kohlenwasserstoffen bestehende Flüssigkeit (Carbonylzahl a51), die durch Einwirkung von Kohlenoxyd und Wasserstoff auf ein Diisobutylen-Diisobutan-Gemisch (Kp. = 98 bis x05°, Olefingehalt 8o °/o) bei 1x5° und unter ioo Atm. Druck in Gegenwart von metallischem Kobalt erhalten worden ist, enthält o, i1 °/o Kobalt in gelöster Form. Man erhitzt sie in einer Rollbombe mit io °/o ihres Gewichts gekörnter Aktivkohle 3 Stunden lang auf i2o° und preßt gleichzeitig Wasserstoff von Zoo Atm. auf. Die Flüssigkeit enthält nach dieser Behandlung noch weniger als o,oo5 °/o Kobalt (Carbonylzahl 1¢6) und ist wasserhell.The liquids treated according to the present process are completely or partially metal-free, which particularly facilitates the separation and recovery of the oxygen-containing products. The oxygen-containing compounds can be more or less hydrogenated during the treatment. By suitably coordinating the process conditions, it can easily be achieved that complete hydrogenation of the oxygen-containing compounds does not occur. Example i A liquid consisting of aldehydes, ketones, alcohols and hydrocarbons (carbonyl number 158), which by the action of carbon oxide and hydrogen on a hydrocarbon mixture (bp = 50 to 100 °, olefin content 45%) at 130 ° and below no atm. Pressure has been obtained in the presence of metallic cobalt; contains 0.15 percent by weight cobalt in dissolved form. They are allowed to trickle at a rate of 10 1 per hour through a vertical high-pressure pipe with a capacity of 25 liters and which is charged with pumice stone, while at the same time hydrogen of 25 atmospheres is poured in. Pressure. The draining liquid (carbonyl number 15o), in contrast to the flowing liquid, remains completely clear even after standing for a long time, it only contains 0.02 percent by weight of cobalt. EXAMPLE 2 A liquid (carbonyl number a51) consisting of aldehydes, ketones, alcohols and hydrocarbons, which by the action of carbon oxide and hydrogen on a diisobutylene-diisobutane mixture (bp = 98 to x05 °, olefin content 80 ° / o) at 1x5 ° and under ioo atm. Pressure obtained in the presence of metallic cobalt contains 0.1% cobalt in dissolved form. They are heated in a roll-top bomb with 10% of their weight granulated activated charcoal for 3 hours at 120 ° and at the same time hydrogen is pressed from Zoo Atm. on. After this treatment, the liquid still contains less than 0.05% cobalt (carbonyl number 1 [6) and is clear as water.
