Description
Verfabren zur Reinigung von flüssigen Harzen. Es ist bekannt, daß sogenanntes flüssiges Harz, welches bei der Papierfabrikation aus Holz gewonnen wird und in der Hauptsache, wie in der Literatur zu finden ist, aus Harz und Fettsäuren besteht, durch Destillation gereinigt wird.Procedure for cleaning liquid resins. It is known that So-called liquid resin, which is obtained from wood during paper manufacture is and mainly, as can be found in the literature, from resin and fatty acids is purified by distillation.
Bei dieser Destillation treten aber bekanntlich weitgehende Zersetzungen ein, die den von vornherein in dem flüssigen Harz enthaltenen geringen Pechgehalt stark vermehren und das Endprodukt erheblich verteuern.However, as is known, extensive decomposition occurs in this distillation one that eliminates the low pitch content inherent in the liquid resin multiply and make the end product considerably more expensive.
Es ist weiter bekannt, daß asphaltartige Stoffe, wie sie in den Mineralölen und Teerölen suspendiert vorkommen, durch Behandlung mit Benzin quantitativ bestimmt werden können.It is also known that asphalt-like substances, such as those in mineral oils and tar oils occur in suspension, quantified by treatment with gasoline can be.
Im Gegensatz hierzu sind die pechartigen Bestandteile des flüssigen Harzes ganz anders zusammengesetzt als die asphaltartigenStoffe des Mineralöls und Teers. Insbesondere zeichnen sie sich durch hohe Verseifungszahl und Säurezahl aus, sind also chemisch vom Asphalt des Teeres und des Petroleums grundverschieden, ebenfalls ihre Lösungsverhältnisse.In contrast, the pitch-like components of the liquid Resin is composed quite differently than the asphalt-like substances of mineral oil and Tar. In particular, they are characterized by a high saponification number and acid number, are therefore chemically fundamentally different from the asphalt of tar and petroleum, as well their solution relationships.
Man kann gemäß den bekannten Verfahren beobachten, daß beim Zufügen von Benzin zu dem flüssigen Harz keine Ausfällung des Peches, das übrigens zum Teil in dem flüssigen Harz gelöst ist, eintritt, und es war überrasc'hend, daß bei starker Verdünnung die Ausfällung dieses Peches beginnt und vollkommen wird.It can be observed, according to the known methods, that when adding from gasoline to the liquid resin no precipitation of the pitch, which incidentally is partly is dissolved in the liquid resin occurs, and it was surprising that with strong Dilution begins the precipitation of this pitch and becomes perfect.
Durch dieses Niederschlagen des geringen Pechgehaltes bleiben die wertvollen organischen Säuren.des flüssigen Harzes unversehrt und werden auch nicht verändert, wenn das Lösungsmittel bei niederer Temperatur abdestilliert -wird.Due to this precipitation of the low pitch content, the valuable organic acids. of the liquid resin and will not be damaged changed when the solvent is distilled off at low temperature.
Die in dem Flußharz enthaltenen organischen Säuren befähigen es, gute Seifen zu bilden, und es wird, außer in der Seifenindustrie, auch in Mischungen verwendet für wasserlösliche öle (Bohröl, Lederöl, Textilöl usw.). Bei allen diesen Verwendungsarten stellt sich aber der Nachteil heraus, daß nach Fertigstellung des Produktes sich nachträglich wieder Niederschläge, bestehend aus pechartigen Anteilen, bilden, die beim Verbrauch der Produkte hinderlich wirken. Vor allem ist die Klebrigkeit ein Mißstand.The organic acids contained in the flow resin enable it to produce good Forming soaps, and it is, except in the soap industry, also in mixtures used for water-soluble oils (drilling oil, leather oil, textile oil, etc.). With all of these Types of use turns out to be the disadvantage that after completion of the Product is subsequently precipitated, consisting of pitch-like fractions, that act as a hindrance to the consumption of the products. Most importantly is the stickiness a grievance.
Durch vorliegende Erfindung wird nun ein von pechartigen Bestandteilen freies, flüssiges Harz erzielt, das, weil es in vielen Fällen das Olein ersetzen kann, als Edelprodukt anzusprechen ist.The present invention now becomes one of pitch-like ingredients free, liquid resin is achieved because in many cases it replaces the olein can be addressed as a noble product.
Der Gegenstand der Erfindung ist dadurch gekennzeichnet, daß die pechartigen Bestandteile aus dem Harz zur Ausfällung gebracht werden. Weitere Einzelheiten sind im folgenden geschildert - Wenn man zur Lösung des Harzes kettenförmig ungesättigte Kohlenwasserstoffe, ringförmig gesättigte Kohlenwasserstoffe, namentlich aber Methan-Kohlenwasserstoffe anwendet, tritt beim weiteren Zusatz dieser Lösungsmittel überraschenderweise eine Fällung ein, und zwar fallen gerade die pechartigen :ßestandteile aus.The object of the invention is characterized in that the pitch-like constituents are caused to precipitate out of the resin. Further details are given below - If chain-shaped unsaturated hydrocarbons, ring-shaped saturated hydrocarbons, but especially methane hydrocarbons, are used to dissolve the resin, precipitation surprisingly occurs when these solvents are further added, and it is precisely the pitch-like constituents that precipitate.
Pie Verdünnung ist bei den verschiedenen Flußharzen nicht immer dieselbe. In einem Falle tritt die Fällung bei 1: 3 ein, im anderen Falle bei 1: 5 oder I - 7. The dilution is not always the same for the different flow resins. In one case the precipitation occurs at 1: 3 , in the other case at 1: 5 or I - 7.
Durch einfache Filtration oder Abgießen werden die beiden Teile getrennt und durch Verdampfen des leicht siedenden Lösungsmittels wird ein flüssiges Harz gewonnen, das keine pechartigen Bestandteile mehr ausscheidet. B e i s p i e 1. ioo kg Flußharz werden mit gleichen Teilen Petrolätlier verrührt, bis eine Lösung bzw. dünnflüssige Emulsion eingetreten ist. Alsdann wird weiter Petroläther zugefügt, bis sich die festen Bestandteile als braune bis schwarze Flocken niederschlagen. Alsdann wird die klare Lösung abfiltriert oder abgegossen und der Petroläther verdampft.The two parts are separated by simple filtration or pouring, and by evaporation of the low-boiling solvent, a liquid resin is obtained that no longer separates pitch-like components. B ice p y 1 kg ioo Flußharz are stirred Petrolätlier with equal parts, has occurred until a solution or low viscosity emulsion. Then petroleum ether is added until the solid constituents precipitate as brown to black flakes. The clear solution is then filtered off or poured off and the petroleum ether is evaporated.
