Description
Verfahren zur Reinigung von Rohparaffin. Bei der Behandlung von Rohparaffin mit sauerstoffhaltigen Gasen treten Verharzungen ein, die eine Oxydation zu wertvollen Produkten erschweren oder verhindern und die Apparate verschmieren. Die bekannten Verfahren, durch die aus dem Rohparaffin ein weißes oxydationsfähiges Paraffin gewonnen werden kann, sind' umständlich und kostspielig.Process for purifying raw paraffin. When treating raw paraffin With oxygen-containing gases resinification occurs, which makes an oxidation valuable Complicate or prevent products and smear the equipment. The known Process by which a white, oxidizable paraffin is obtained from the raw paraffin are 'cumbersome and costly.
Es wurde nun gefunden, daß man in sehr einfacher Weise ein für die Weiterverarbeitung insbesondere die Oxydation vorzüglich geeignetes Paraffin erhält, wenn man das Rohparaffin einerseits mit Bleichmitteln, andererseits mit überhitztem Wasserdampf im Vakuum behandelt. Zweckmäßig schickt man die Bleichung voraus und bläst dann das Paraffin unter einem stärken Vakuum mit überhitztem Wasserdampf aus. Ein derart vorbehandeltes, noch braunes bis braungelbes Rohparaffin läßt sich ausgezeichnet mit Sauerstoff oder solchen enthaltenden Gasen oxydieren. Dabei zeigt es sich, daß während der Oxydation eine Aufhellung der Farbe der Oxydationsprodukte in hellgelb eintritt, während ein nur mit Bleicherden behandeltes, gelbes Rohparaffin während des Blasens mit Luft umgekehrt eine tiefbraune Farbe annimmt und sich zur Oxydation nicht eignet. Die aus dem gemäß vorliegenden Verfahren gereinigten Paraffin erhältlichen Oxydationsprodukte des Rohparaffins sind den aus weißem Tafelparaffin hergestellten vollkommen gleichwertig. Beispiel. Rohparaffin, wird ein- bis zweimal bei zzo° mit etwa 5 bis zo Prozent Bleicherde, z. B. Tonsil oder Frankonit, behandelt und das erhaltene braune bis braungelbe Produkt zwischen 140 ' und 170 ' mit überhitztem Wasserdampf bei 5 mm Quecksilberdruck so lange geblasen, bis etwa der zwanzigste Teil des angewandten Robparaffins übergegangen ist. Das geblasene Produkt hat einen angenehmen teerfreien Geruch und kann unmittelbar zu wertvollen Produkten oxydiert werden.It has now been found that one for the Further processing, especially the oxidation, preserves particularly suitable paraffin, if you use the slack wax on the one hand with bleach, on the other hand with superheated Treated water vapor in vacuo. Appropriately, one sends the bleaching ahead and then blows out the paraffin under a strong vacuum with superheated steam. A raw paraffin which has been pretreated in this way and is still brown to brown-yellow can be excellent oxidize with oxygen or such containing gases. It turns out that During the oxidation, the color of the oxidation products lightened to light yellow occurs while a yellow raw paraffin treated only with fuller's earth during of blowing with air, conversely, takes on a deep brown color and becomes oxidized not suitable. Those obtainable from the paraffin purified according to the present process Oxidation products of raw paraffin are those made from white table paraffin completely equivalent. Example. Raw paraffin, is used once or twice at zzo ° about 5 to zo percent fuller's earth, e.g. B. Tonsil or Frankonit, treated and that brown to brownish yellow product obtained between 140 'and 170' with overheated Water vapor blown at 5 mm mercury pressure until about the twentieth Part of the applied sealant paraffin has passed. The blown product has a pleasant tar-free smell and can be oxidized directly to valuable products will.
