Description
Verfahren zur Reinigung von Rohmontanwachs. Es erschien bisher zweckmäßig, vor der Behandlung des Rohmontanwachses mit Schwefelsäure zwecks Reinigung eine solche mit Salpetersäure vorausgehen zu lassen, weil das hierdurch entstehende sogenannte »Nitrowachs« der Einwirkung der Schwefelsäure mit oder ohne Paraffinbeimischung zugänglicher war.Process for cleaning raw montan wax. So far it has seemed appropriate before treating the raw montan wax with sulfuric acid for cleaning to precede those with nitric acid, because the so-called "Nitro wax" from the action of sulfuric acid with or without the addition of paraffin was more accessible.
Gemäß dem; vorliegenden Verfahren soll die -gesonderte Vorbehandlung mit ,Salpetersäure in Wegfall kommen.According to the; In the present process, the - separate pretreatment with nitric acid should be dispensed with.
Der Vorgang beruht auf einer Kombination der Salpeter- und Schwefelsäureeinwirkung in, der Weise, daß man Mischsäure in einem. einzigen Arbeitsgang zur Anwendung bringt.The process is based on a combination of the action of nitric and sulfuric acid in, in such a way that one mixed acid in one. applies a single operation.
Ebenso kann in einem einzigen Prozeß mittels Misch säiureeinwirkung und gleichzeitiger Destillation mit überhitztem Wasserdampf oder anderen Mitteln, welche sich bei der hohen Temperatur indifferent verhalten, mit oder ohne Vakuum ohne vorhergehende Harzabscheidung, wie sie in sonst bekannter Weise raffiniert werden.Likewise, in a single process by means of mixed acid action and simultaneous distillation with superheated steam or other means, which behave indifferently at the high temperature, with or without vacuum without prior resin deposition, as refined in an otherwise known way will.
Es tritt auf diese Weise nicht nur die gewünschte Harzabscheidung neben Raffination und Meiche des dabei entstehenden Spaltkörpers in d'iesein einzigen Arbeitsgang ein, sondern es werden auch die entstehenden nitrosen Gase sofort wieder zur Regenerierung der gleichfalls sich bildenden schwefligen Säure verwandt. Bei den bisher bekannten Verfahren gingen beide wertvollen Zersetzungsstoffe der angewandten Säuren durch ihre getrennte Verwendung verloren. Da im gleichen Verlaufe die Neubildung zersetzter Schwefelsäure stattfindet, tritt dadurch eine ganz bedeutende Ersparnis an dieser Säure ein.In this way, not only does the desired resin deposition occur in addition to refining and meiche of the resulting fissure body in d'iesein is the only one Operation, but the nitrous gases that develop are also immediately restored related to the regeneration of the sulphurous acid which is also formed. at the previously known processes were both valuable decomposition substances of the applied Acids lost through their separate use. Since in the same course the new formation decomposed sulfuric acid takes place, there is a very significant saving at this acid.
Durch dieses Verfahren ist es ferner ermöglicht, ohne vorherige Harzabscheidung, wie dies ein bekanntes Verfahren bedingt, eine Raffination des Rohmontanwachses mit überhitztere .Wasserdampf oder anderen indifferenten Mitteln auszuführen.This process also makes it possible, without prior resin deposition, as this requires a known process, a refining of the raw montan wax to be carried out with superheated steam or other inert means.
Der Vorgang ist der gleiche, wie oben beschrieben. Das hierbei ausgeschiedene und als Destillationsrückstand hinterbleibende sogenannte Harz :besitzt die bekannten vorteilhaften und in anderer Patentschrift bereits gekennzeichneten Eigenschaften, ohne eine von dem Montanwachs getrennte Destillation erfahren zu müssen.The process is the same as described above. The one eliminated here and what is known as resin remaining as distillation residue: possesses the known advantageous properties already identified in another patent specification, without having to experience a separate distillation from the montan wax.
