Verfahren zur Herstellung von Ultramarinen und ähnlichen FarbkörpernProcess for the production of ultramarines and similar color bodies

Das Ziel dieser Erfindung ist die Herstellung von Ultramarinen und ähnlichen Farbkörpern auf hydrothermalem Wege.The aim of this invention is the production of ultramarines and similar colored bodies by hydrothermal means.
Nach dem heutigen Stand der Technik werden Ultramarinfarben dureh Glühen des Rohgemisches der Ausgangsstoffe in Tiegeln hergestellt. Ursprünglich wurde dieses Glühen in zwei Stufen durchgeführt. Das Produkt der ersten Stufe war ein "grünes11 Ultramarin· Dieses wurde nach einer geeigneten Aufbereitung einer zweiten, diesmal oxydierenden Glühung unterworfen und da· bekannte blaue Ultramarin erhalten. Heute jedoch worden die Ultramarine in einem Brand erzeugt. Hierbei mud aber die zweite Phase oxydierend geführt werden,According to the current state of the art, ultramarine colors are produced by annealing the raw mixture of raw materials in crucibles. Originally, this annealing was carried out in two stages. The product of the first stage was a "green 11 ultramarine. This was subjected to a second, this time oxidizing, annealing after a suitable preparation and the known blue ultramarine was obtained. Today, however, the ultramarines are produced in a fire. The second phase, however, has to be oxidizing be led

Der Brand erfolgt in relativ kleinen Tiegeln in periodischen Öfen und dauert für gewöhnlich 10 bis 14 Tage«The firing takes place periodically in relatively small crucibles Ovens and usually lasts 10 to 14 days «
Entsprechend der vorliegenden Erfindung ist es nun gelungen, von des Brennen abzugehen und die Ultramarinblldung hydrothermal herbeizuführen· Hierzu kann von denselben Rohstoffen ausgegangen werden «it der Einschränkung, daß als Sohwefeitriger nur Sulfide und/oder Polysulfide verwendet werden, denn ein· Reduktion eines Sulfates ait Kohle ist hydrothermal undurchführbar.According to the present invention it has now been possible to to go away from the stinging and the ultramarine blooming to bring about hydrothermally · For this purpose, the same raw materials can be assumed «with the restriction that as Sohwefeitriger only sulfides and / or polysulfides can be used, because a · reduction of a sulfate ait coal is hydrothermally impracticable.
Das Gemenge wird mehlfein gemahlen und anschließend ggf. granuliert oder gepreßt und daraufhin «in«r Dampfh&rtung unterworfen, welehe mit Sattda*pf odmr überhitztem Dampf durchgeführt werden kann. Das Kochen im Wasser ist nioht ausreichend.The mixture is finely ground flour and then, if necessary, pelletized or pressed and then subjected to "in" r Dampfh & Maintenance, welehe with Sattda * pf ODMR superheated steam can be performed. Boiling in water is not enough.

Vorteilhaft werden Sattdampfdrucke von 5 bis 20 atü verwendet. Eine Überhitzung des Dampfes wirkt sich besonders bei kleineren Drucken reaktionsbeschleunigend aus.Saturated steam pressures of 5 to 20 atmospheres are advantageous used. Overheating of the steam has the effect of accelerating the reaction, especially at lower pressures the end.
Erhalten werden zumeist blass bis grünlich gefärbte Ultramarine, welche beim anschließenden oxydierenden Glühen zwischen 500 und 700°C blau werden.Mostly pale to greenish colored ultramarines are obtained, which are then oxidized Annealing between 500 and 700 ° C will turn blue.
Durch Änderung der Gemengezusammensetzung, sowie durch Ersatz eines Teiles des Natriums, durch Kalium oder Erdalkalimetall kennen auch beim hydrothermal hergestellten Ultramarin die Farbtönungen beeinflußt werden.By changing the batch composition, as well as by Replacement of a part of the sodium by potassium or alkaline earth metal also know in the case of hydrothermal production Ultramarine affects the color tones.
Gegenüber der heute üblichen Ultramarinherstellung liegt der Vorteil des hydrothermalen Verfahrens darin, daß wesentlich kürzere Herstellungszeiten möglich«erden. Die hydrothermale Behandlung dauert Stunden, etwa k bis 16 und das anschließende Glühen, z.B. im Wirbelbett, ebenso nur Stunden, und zwar 1 bis 2 oder weniger.The advantage of the hydrothermal process compared with the production of ultramarine, which is customary today, is that considerably shorter production times are possible. The hydrothermal treatment lasts hours, approximately k to 16 hours, and the subsequent annealing, for example in a fluidized bed, also only takes hours, namely 1 to 2 or less.
Darüberhinaus ist der Prozeß nach dem erfindungegemäßen Verfahren sehr gut regelbar und damit auch das Produkt von gleichmäßiger Güte. Ebenso können Wechsel in der Produktion der jeweils gewünschten Produkte schnell und sicher vorgenommen werden.In addition, the process is according to the invention The process is very easy to regulate and therefore the product is of uniform quality. Changes in the Production of the desired products can be carried out quickly and safely.

Es iat auch bereits vorgeschlagen worden, Ultraaarinfarbetoffe durch Kochen in Vasrfer ait oder ohne Druck von Zeolithen unter Zugabe von Sulfiden herzustellen. Es liegt auf der Hand, das dieses Verfahren allein schon lsi Hinblick auf die kostspieligen Auegangeprodukt· keine praktische Bedeutung erlangen konnte.It has also been proposed to use ultra-hair dye by boiling in vasrfer ait or without pressure of zeolites with the addition of sulfides. It is obvious that this procedure alone is already in view of the expensive auegangean · could not acquire any practical significance.
