Description
Verfahren zum Bleichen von harzfreiem Montanwachs Die bisher bekannten Verfahren zum Bleichen von 'Montanwachs durch Oxydation gehen von dem rohen oder entharzten 1Iontanwachs aus. In letzterem Falle ist der Verbrauch an Oxydationsmitteln geringer als bei Verwendung von rohem Montanwachs.Process for bleaching resin-free montan wax The previously known Process for bleaching montan wax by oxidation start from the raw or remove resin from 1ionan wax. In the latter case there is the consumption of oxidizing agents less than when using raw montan wax.
Es hat sich nun gezeigt, daß man eine noch weitergehende Ersparnis an Oxydationsmitteln dadurch erzielen kann, daß man aus dem entharzten Rohprodukt wachsreiche Produkte darstellt und diese, gegebenenfalls nach Zusatz indifferenter Verdünnungsmittel, durch Behandlung in saurem, alkalischem oder neutralem Medium mit Oxydationsmitteln bleicht. Man kann wachsreichere Produkte aus den Ausgangsstoffen z. B. gewinnen, indem man auf diese Lösungsmittel, wie Methyl- oder Äthylalkohol oder andere Alkohole, Essigester, Benzin, Benzol-Alkohol-Gemische oder auch andere Lösungsmittelgemische usw., einwirken läßt. Die so erhaltenen -wachsreicheren und an dunklen Bestandteilen ärmeren Fraktionen lassen sich mit einem sehr geringen Aufwand an Oxydationsmitteln aufhellen.It has now been shown that you can save even more of oxidizing agents can be achieved by converting the de-resinified crude product represents wax-rich products and these, if necessary after addition, more indifferent Diluent, by treatment in acidic, alkaline or neutral medium bleaches with oxidizing agents. You can make products richer in wax from the starting materials z. B. win by acting on these solvents such as methyl or ethyl alcohol or other alcohols, ethyl acetate, gasoline, benzene-alcohol mixtures or others Solvent mixtures, etc., can act. The so obtained -waxier and fractions poorer in dark constituents can be obtained with a very small fraction Lighten the amount of oxidizing agents.
Anstatt entharztes Montanwachs in der beschriebenen `'leise zu zerlegen, kann man auch aus bitumenhaltiger Kohle durch Extraktion mit vorwiegend Wachs aufnehmenden Lösungsmitteln unmittelbar ein für die Bleichung besonders geeignetes Ausgangs. produkt ge«znnen. Auch Substitutionsproduk-te, z. B. Chlorierungsprodukte, des Montanwachses oder beispielsweise durch Verseifung zu erhaltende Spaltkörper von Montanwachs lassen sich in der angegebenen Weise bleichen.Instead of quietly disassembling de-treated montan wax in the manner described, can also be obtained from bituminous coal by extraction with predominantly wax Solvents directly a particularly suitable starting point for bleaching. product. Substitution products, e.g. B. chlorination products of montan wax or, for example, leave gap bodies of montan wax to be obtained by saponification bleach in the specified manner.
Nach Patent 386708 ist es zwar bekannt, daß man aus Rohmontanwachs durch Behandlung mit Lösungsmitteln zum Teil wachsreichere und nach den damals bekannten Reinigungsmethoden besonders leicht raffinierbare Bestandteile gewinnen kann. Es war jedoch aus diesem Patent nicht zu erschließen, daß auch die erst neuerdings gefundene ganz andersartige oxydative Raffination z. B. mittels Chromsäure in schwefelsaurer Lösung besonders vorteilhaft auf bestimmte Montanwachsbestandteile, insbesondere die reinen 'Wachsanteile, anwendbar sein würde. Denn es war ja in keiner Weise bekannt, in welcher Weise diese Oxydationsmittel auf die einzelnen Wachskörper einwirken.According to patent 386708 it is known that by treatment with solvents it is possible to obtain from raw montan wax components that are in part richer in wax and particularly easily refined using the purification methods known at the time. However, it could not be inferred from this patent that the recently discovered completely different oxidative refining z. B. by means of chromic acid in sulfuric acid solution would be particularly advantageous to certain montan wax components, especially the pure 'wax components, applicable. For it was by no means known in what way these oxidizing agents act on the individual wax bodies.
Die Behandlung der aus Rohmontanwachs durch Verseifung gewonnenen Wachsalkohole mit Kaliumpermanganat oder Kaliumbichromat ist bekannt und wird nicht beansprucht. Beispiel Rohmontanwachs wird durch kalten Alkohol von seinen harzigen Anteilen (170'0) befreit; das entharzte Wachs wird darauf mit heißem Alkohol wiederholt ausgekocht und heiß filtriert, wodurch in den Filtraten schließlich ein wesentlich helleres, wachsreicheres Produkt in einer Ausbeute bis zu 480,'0 erhalten wird. Dieses läßt sich mit der gleichen Menge Natriumbichromat in Gegenwart von verdüiuiter Scli%%,efrls:iure zu einem fast weißen -Wachs aufhellen, während der alkoholunlösliche Rückstand (3 5 0;.'0) bei gleicher Behandlung nur ein braunes Produkt ergibt.The treatment of those obtained from raw montan wax by saponification Waxy alcohols with potassium permanganate or potassium dichromate is known and will not claimed. Example raw montan wax is made from its resinous by cold alcohol Shares (170'0) exempt; the resin-removed wax is then repeated with hot alcohol boiled out and filtered hot, which ultimately results in an essential in the filtrates lighter, more wax-rich product is obtained in a yield of up to 480.0. This can be done with the same amount of sodium dichromate in the presence from Verdüiuiter Scli %%, efrls: iure to an almost white wax, while the alcohol-insoluble residue (3 5 0;. '0) with the same treatment only a brown Product results.
