Description
Verfahren zur Oxydation von Colophonium. Man hat bereits vorgeschlagen, Colophonium dadurch zu härten, daß man es einer Oxydation durch Behandeln mit Luft oder Sauerstoff unterwirft.Process for the oxidation of rosin. It has already been suggested To harden rosin by treating it with air to oxidize it or subject to oxygen.
Dieses Verfahren wird derart ausgeführt, daß man Luft oder Sauerstoff durch eine Mischung des geschmolzenen Harzes mit trocknendem oder nichttrocknendem 01 leitet. Man hat ferner vorgeschlagen, die Oxydation derart vorzunehmen, daß man über gepulvertes, in dünner Schicht ausgebreitetes Colophonium bei allmählich steigender Temperatur so lange Luft leitet, bis der Schmelzpunkt nicht mehr wesentlich steigt.This process is performed such that air or oxygen is passed through a mixture of the molten resin with drying or non-drying 01. It has also been proposed to carry out the oxidation in such a way that air is passed over powdered rosin spread in a thin layer at a gradually increasing temperature until the melting point no longer increases significantly.
Diese Verfahren weisen aber wesentliche technische Nachteile auf. Das erstere Verfahren erfordert stets den Zusatz anderer trocknender oder oxydierender Mittel. Bei dem direkten Oxydationsverfahren muß sehr vorsichtig gearbeitet werden, um überhitzungen zu vermeiden.However, these processes have significant technical disadvantages. The former method always requires the addition of other drying or oxidizing agents Middle. The direct oxidation process must be worked very carefully, to avoid overheating.
Es hat sich nun gezeigt, und das bildet den Gegenstand der Erfindung, daß die Oxydation sehr viel einfacher und sicherer durchgeführt werden kann, wenn man das Colophonium bei Gegenwart von Katalysatoren oxydiert. Zweckmäßig wird das Colophonium vor der Oxydation in einem der üblichen leicht siedenden Harzlösungsmittel aufgelöst. Das Lösungsmittel wird nach der Oxydation <furch Abdestillation oder auf andere geeignete Weise wieder entfernt, so daß also das reine oxydierte Colophonium zurückbleibt. Die Oxydation kann auch unter Druck erfolgen.It has now been shown, and this forms the subject of the invention, that the oxidation can be carried out much easier and safer if the rosin is oxidized in the presence of catalysts. That will be useful Colophony in one of the usual low-boiling resin solvents before oxidation dissolved. After the oxidation, the solvent is removed by distillation or removed again in another suitable manner, so that the pure oxidized rosin remains behind. The oxidation can also take place under pressure.
Ausführungsbeispiel. ioo kg Colophonium werden in i5o kg Eisessig gelöst und unter Druck bei etwa 5 Atm. bei Gegenwart eines geeigneten Katalysators erwärmt. Hierauf wird etwa i kg Natriumnitrat zugegeben und unter Drucke so lange Sauerstoff eingeleitet, bis nichts mehr aufgenommen wird. Das Lösungsmittel wird dann abdestilliert. Der Rückstand stellt einen höher als das Ausgangsmaterial siedenden, nicht klebenden Körper dar, der für eine große Reihe von Verwendungszwecken geeignet ist, beispielsweise zur Herstellung von Schellackersatz, zur Verwendung als Isoliermittel sowie in der Lack- und Seifenindustrie. So lassen sich unter Verwendung oxydierten Colophoniums vorzügliche Harzseifen herstellen, weil das Colophonium durch die Oxydation die klebrigen Eigenschaften vollkommen verloren hat.Embodiment. 100 kg of rosin are dissolved in 150 kg of glacial acetic acid dissolved and under pressure at about 5 atm. in the presence of a suitable catalyst warmed up. About 1 kg of sodium nitrate is then added and under pressure for so long Oxygen is introduced until nothing is absorbed. The solvent will then distilled off. The residue represents a higher boiling point than the starting material, non-adhesive body that is suitable for a wide variety of uses is, for example, for the production of shellac substitutes, for use as an insulating agent as well as in the paint and soap industry. So can be oxidized using Rosin make excellent resin soaps because the rosin is oxidized has completely lost its sticky properties.
