Description
Verfahren zur Herstellung von trocknenden Bindemitteln Bei der Herstellung von synthetischem Kautschule durch Behandlung des aus Butandiol gewonnenen Rohbutadiens mit Alkalihy droxyd bei gewöhnlicher oder schwach erhöhter Temperatur erhält .man Abfallöle, die gewöhnlich als Laugeöle bezeichnet werden. Diese Öle haben an und für sich keinerlei trocknende Eigenschaften und ergeben auch, für sich allein als Anstrichmittel angewandt, keine genügend wasserfesten Überzüge, weisen also die Voraussetzungen nicht auf, die man für die Herstellung von Bindemitteln für Anstrich- und Kittzwecke fordert.Method of making drying binders During manufacture of synthetic chewing school by treating the raw butadiene obtained from butanediol with alkali hydroxide at an ordinary or slightly elevated temperature, one obtains Waste oils, commonly referred to as lye oils. These oils have on and for themselves no drying properties and also result, for themselves as Paints applied, no sufficiently waterproof coatings, so they have Do not meet the requirements for the production of binders for paints and calls for putty.
Es wurde nun gefunden, daß es möglich ist, diese Laugeöle für den obengenannten Verwendungszweck mit bestem Erfolg zu benutzen, wenn man sie nicht für sich, sondern zusammen mit den Rückstandsölen anwendet, die durch Wasserabspaltung aus Butandiol (Butylenglykol), also bei der Herstellung des kohbutadiens selbst, entstehen. Diese Öle werden allgemein als Butadienöle oder Heizöle bezeichnet; sie werden nach den Verfahren der Patente 857 997, 881 563, 888 908, 888 910 und 888 9i i in trocknende Bindemittel überführt.It has now been found that it is possible to use these lye oils for the above-mentioned purpose with the best possible results if they are not used on their own but together with the residual oils that are produced by dehydration from butanediol (butylene glycol), i.e. in the production of the kohbutadiens themselves. These oils are commonly referred to as butadiene oils or fuel oils; they are according to the procedures of the patents 857,997, 1 563 88, 888 9 0 8 888 888 910 and 9i i transferred to drying binders.
Das obengenannte Laugeöl kann den Butaadienölen entweder nach den Behandlungen gemäß den obigen Patenten zugemischt werden, oder es wird noch zweckmäßiger zusammen mit dem Butadienöl der Wärmebehandlung, der Einwirkung kondensierend wirkender, starker Säuren oder saurer Salze oder beiden Einwirkungsarten unterworfen, wobei das bei der Reaktion auftretende oder abgespaltene Wasser und gegebenenfalls leicht flüchtige Destillate zweckmäßig laufend entfernt werden. Auch können dabei Wärmeüberträger, zweckmäßig Wasserdampf selbst, zugeleitet werden. Beispiel ioo Gewichtsteile Laugeöl, herrührend aus der Alkalibehandlung des Rohbutadiens, werden mit ioo bis Zoo Gewichtsteilen Butadienö:l, herrührend von der Butadienherstellung aus Butandiol, gemischt. Diese Mischung wird mit 2 Gewichtsteilen einer stark kondensierend wirkenden Säure, beispielsweise Überchlorsäure, versetzt und die Umsetzung durch leichte Erwärmung eingeleitet. Man erhält nach Abdestillieren von leichtflüchtigen Anteilen und Wasser ein mittelflüssiges Öl, das selbsttrocknende Eigenschaften aufweist. Dieses Öl kann als Bindemittel zur Herstellung von selbsttrocknenden Isolieranstrichen und als Bindemittel für Verglasungskittmassen verwendet werden.The above-mentioned lye oil can be either after the butaadiene oils Treatments according to the above patents can be admixed, or it becomes more convenient together with the butadiene oil of the heat treatment, the action of condensing, subjected to strong acids or acidic salts or both types of action, whereby the water which occurs or is split off during the reaction and, if appropriate, easily volatile distillates are expediently continuously removed. Heat exchangers, expediently water vapor itself are supplied. Example 100 parts by weight of lye oil, resulting from the alkali treatment of the raw butadiene, ioo to zoo parts by weight Butadiene oil: oil, resulting from the production of butadiene from butanediol, mixed. These Mixture is with 2 parts by weight of a strongly condensing acid, for example Overchloric acid, added and the reaction initiated by gentle heating. After distilling off volatile components and water, a medium liquid is obtained Oil that has self-drying properties. This oil can act as a binder for the production of self-drying insulating paints and as a binder for Glazing putty can be used.
Während das Laugeöl in ursprünglichem Zustand keinerlei selbsttrocknende Eigenschaften aufweist und in keiner Weise wasserbeständige Überzüge od. dgl. ergibt, ergeben die nach obigen Verfahren hergestellten Öle allen Anforderungen dieser Art in jeder Weise genügende Massen.While the lye oil in its original state does not have any self-drying properties Has properties and in no way results in water-resistant coatings or the like, the oils produced according to the above process meet all requirements of this type sufficient masses in every way.
