Description
Verfahren zur Gewinnung organischer Säuren In dein Hauptpatent 541 gio ist ein Verfahren zur Gewinnung organischer Säuren beschrieben, bei dem man die durch Oxvdation von festen Paraffinkohlenwasserstoffen, Wachsen u. dgl. erhältlichen rohen Fettsäuren rinem Preßverfahren oder einem Schwitzverfahren bei etwas erhöhter, unterhalb des Schmelzpunktes der in ihnen vorhandenen reinen Fettsäuren liegender Temperatur unterwirft und die hierbei sich verflüssigenden Verunreinigungen abtrennt.Process for the production of organic acids In your main patent 541 gio describes a process for the production of organic acids in which one those obtainable by the oxidation of solid paraffinic hydrocarbons, waxes and the like raw fatty acids in a pressing process or a sweating process for slightly increased, below the melting point of the pure fatty acids present in them Subject to temperature and thereby separating the liquefied impurities.
Es wurde nun gefunden, daß hierbei in einfacher Weise eine weitgehende Trennung der Fettsäuren von den Verunreinigungen erzielt «-erden kann, wenn man vor dem Pressen oder Schwitzen das Oxydationsprodukt einer Destillation, z. B. bei vermindertem oder gewöhnlichem Druck mit oder ohne Anwendung von Katalysatoren oder bzw. und Trägergasen, unterwirft. Hierbei werden die iiii Oxydationsprodukt vorhandenen Oxysäuren in bekannter Weise in ungesättigte Fettsäuren übergeführt, und dadurch wird der Schmelzpunkt und damit auch die Viskosität der bei dem Preß- oder Schwitzverfahren in flüssiger I# orm entfernbaren Verunreinigungen erniedrigt, wodurch die Trennung der festen und flüssigen Anteile außerordentlich erleichtert wird. Es gelingt meist ohne Anwendung besonderen Druckes und ohne schärfere Temperaturregelung, die Abtrennung durchzuführen. Beispiel Rohe, durch Oxydation von Hartparaffin und Behandlung gemäß Patent 492 755 durch Verseifung und Extraktion erhaltene Fettsäuren vom Schmelzpunkt 35 bis 38° «-erden bei einem Druck von 16 mm Ouecksilber rasch destilliert. i ooo Teile des Destillats werden auf 12 bis i3° abgekühlt, in Preßtücher eingeschlagen und unter einer Presse bei etwa i atü abgepreßt. Der flüssige Anteil, etwa 25o Teile, besteht aus hellgefärbten ungesättigten Säuren, der feste Anteil, etwa 75o Teile, besteht aus harten, hellen Fettsäuren vom Schmelzpunkt 45 bis 48°.It has now been found that this is a far-reaching one in a simple manner Separation of the fatty acids from the impurities can be achieved, if one before pressing or sweating, the oxidation product of a distillation, e.g. B. at reduced or ordinary pressure with or without the use of catalysts or or and carrier gases. Here the iiii oxidation products are present Oxy acids converted into unsaturated fatty acids in a known manner, and thereby becomes the melting point and thus also the viscosity of the pressing or sweating process in liquid I # orm removes impurities, reducing the separation the solid and liquid components is greatly facilitated. It usually works without applying special pressure and without stricter temperature control, the separation perform. Example raw, by oxidation of hard paraffin and treatment according to Patent 492,755 fatty acids obtained by saponification and extraction from the melting point 35 to 38 ° "earth quickly distilled at a pressure of 16 mm mercury. i ooo Parts of the distillate are cooled to 12 to 13 ° and wrapped in press cloths and squeezed out under a press at about iatu. The liquid part, about 25o parts, consists of light colored unsaturated acids, the solid part, about 75o parts, consists of hard, light-colored fatty acids with a melting point of 45 to 48 °.
