Es wurde nun gefunden, daß ein Katalysator nach dem Hauptpatent und gegebenenfalls nach dem 1. Zusatzpatent eine., erhöhte Beschichtungsfestigkeit aufweist, bei dem die Beschichtung mit der Yanadinpentoxyd und Titandioxyd enthaltenden Masse durch Aufbringen in gelöster bzw. suspendierter Form auf einen auf eine Temperatur von 160 bis 50O0C, insbesondere 270 bis 50O0C, erwärmten Träger erfolgt ist.It has now been found that a catalyst according to the main patent and optionally according to the 1st additional patent has an increased coating strength in which the coating with the mass containing yanadine pentoxide and titanium dioxide is applied in dissolved or suspended form to a temperature of 160 to 50O 0 C, in particular 270 to 50O 0 C, heated carrier has taken place.
Der neue Katalysator weist eine hohe Beschichtungsfestigkeit auf. Während bislang vielfach beim Transport und beim Einfüllen in den Oxydationsreaktor Teile der Beschichtung abbröckelten und somit ein besonders vorsichtiges Handhaben erforderlich war, zeigt der neue Katalysator nur minimalen Abrieb. Ein Abbröckeln der Beschichtung wird nicht mehr beobachtet. Bezüglich der Verwendbarkeit dea Katalysators, der geeigneten Katalysatorträger, gegebenenfalls der Grundierung oder Vorbehandlung der Träger, der Katalysetorbeschichtungsmaase und der Durchführung der Oxydationsreaktionen unter Verwendung des neuen Katalysators besteht kein Unterschied zum Katalysator des Haupt- und 1. Zusatzpatents.The new catalyst has a high coating strength. While so far often during transport and when filling into the Oxidation reactor parts of the coating crumbled and thus Particularly careful handling was required, the new catalyst shows only minimal abrasion. The coating is flaking off is no longer observed. With regard to the usability of the catalyst, the suitable catalyst carrier, if necessary priming or pretreatment of supports, catalyst coating and carrying out oxidation reactions using the new catalyst there is no difference to the catalyst of the main and 1st additional patent.
Die Beschichtung erfolgt derart, daß der gegebenenfalls grundierte Träger auf eine Temperatur zwischen 160 und 5000C, vorzugsweise 270 bis 5000C, insbesondere 280 bis 45O0C, erhitzt wird. Man arbeitet vorteilhaft in einer beheizbaren Dragiertrommel, einem Drehrohrofen oder auf einer vibrierenden Unterlage.The coating is carried out such that the optionally primed backing to a temperature of 160-500 0 C, preferably 270-500 0 C, in particular 280, heated to 45O 0 C. It is advantageous to work in a heatable coating drum, a rotary kiln or on a vibrating base.

Die als Katalysatorbeschichtung verwendete Masse, die in. trockenem Zustand 1 bis 15 Gew>$ Vanadinpentoxyd. und 85 bis 99 Gew. fo Titandioxyd enthalten soll, wird in gelöster bzw. suspendierter Form auf den Träger aufgebracht. Als Lösungs- bzw. Suspensionsmittel wird Wasser oder ein organisches Lösungsmittel..;, wie formamid oder Alkohol, verwendet. Titandioxyd, liegt hierbei im allgemeinen in suspendierter Form, Vanadinpentoxyd bzw. eine Vanadinverbindung, die beim Erhitzen in Vanadinpentoxyd übergeführt wird, im allgemeinen in gelöster Form vor. Im allgemeinen arbeitet man mit einem Brei, der honigartige Konsistenz aufweist» Bei der neuen Beschichtungsweise verdampft das Wasser bzw. das Lösungsmittel praktisch momentan, sobald die Masse mit dem Träger in Berührung kommt. 'The mass used as a catalyst coating, which in the dry state is 1 to 15% by weight of vanadium pentoxide. and should contain 85 to 99 wt. fo titanium dioxide, is applied to the carrier in dissolved or suspended form. The solvent or suspension medium used is water or an organic solvent, such as formamide or alcohol. Titanium dioxide is generally in suspended form, while vanadium pentoxide or a vanadium compound which is converted into vanadium pentoxide on heating is generally in dissolved form. In general, you work with a paste that has a honey-like consistency. With the new coating method, the water or the solvent evaporates almost instantaneously as soon as the mass comes into contact with the carrier. '
Der fertige Katalysator soll 0,05 bis 3, vorzugsweise 0,1 bis 2, insbesondere 0,05 bis 1 G-ew.$ Vanadinpentoxyd enthalten.The finished catalyst should be 0.05 to 3, preferably 0.1 to 2, in particular 0.05 to 1% by weight of vanadium pentoxide.

75 kg S tea tit kugeln mit einem Durchmesser von 6 mm werden in einer Dragiertrommel auf 35O0C erhitzt. Mit einer Sprühvorrichtung werden die heißen Kugeln mit der obengenannten Mischung besprüht. Die Trommel wird von außen beheizt, so daß beim Besprühen kein Temperaturabfall eintritt. Die gesamte Flüssigkeit wird im Moment der Berührung mit der heißen Kugel verdampft. Die Kugeln besitzen eine aktive Masse von 6,14 i<>. Der fertige Katalysator enthält 0,48 fo Yanadinpentoxyd.75 kg S tea tit balls with a diameter of 6 mm are heated in a coating drum at 35O 0 C. The hot balls are sprayed with the above mixture using a spray device. The drum is heated from the outside so that no temperature drop occurs during spraying. All the liquid is evaporated at the moment of contact with the hot ball. The spheres have an active mass of 6.14 i <>. The finished catalyst contains 0.48 fo Yanadinpentoxyd.
fc Läßt man 100 g dieses Katalysators durch ein 3 m langes stehendes Rohr mit einem Durchmesser von 0,25 m fallen, so verliert der Katalysator nur 0,25 $ der aktiven Masse.fc Lets 100 g of this catalyst through a 3 m long standing If a pipe with a diameter of 0.25 m falls, the catalyst only loses $ 0.25 of the active material.
Werden dagegen die Kugeln bei Raumtemperatur in der Dragiertrommel mit der aktiven Masse beschichtet und anschließend bei 2000C getrocknet, so ergibt sich im Fälltest ein Verlust an aktiver Masse durch Abbröckeln von 12. ^.In contrast, if the balls coated at room temperature in the coating drum with the active material and then dried at 200 0 C, a loss of active mass is obtained in Fälltest by crumbling of 12 ^.
Selbstverständlich kann anstelle von Titandioxyd auch eine Lö- w sung einer Titanverbindung verwendet werden, die beim Erhitzen in Titandioxyd übergeführt wird, z.B. alkoholische Lösungen von Titanalkoholaten oder Titantetrachlorid.Of course, a titanium compound may be used instead of titanium dioxide, a solu- w solution are used, which is converted upon heating in titanium dioxide, for example, alcoholic solutions of titanium alcoholates or titanium tetrachloride.
