Description

Verfahren zur Herstellung von vorzugsweise für die Papierleimung verwendbarer ' 1Kontanwachsseife. An und für sich ist es bekannt, Montanwachs, sei es gereinigt oder in Form von Rohmontanwachs, zu verseifen. Die bekannten Verfahren beruhen auf einer Verseifung mit alkoholischem Ätzalkali, gegebenenfalls nach vorausgegangener Lösung des Wachses in einem flüchtigen Kohlenwasserstoff, teilweise nach vorausgegangener Behandlung mit Schwefelsäure oder aber auch unter Verwendungeines Emulgierungsmittels.Process for the production of preferably useful for paper sizing '1 Account wax soap. In and of itself it is known that montan wax, be it purified or in the form of raw montan wax. The known methods are based on saponification with alcoholic caustic alkali, if necessary after a previous one Solution of the wax in a volatile hydrocarbon, partly according to the preceding Treatment with sulfuric acid or with the use of an emulsifying agent.

Das vorliegende Verfahren bezweckt nun die Herstellung von Montanwachsseife aus dem durch Chlorzinklösung bei erhöhter Temperatur gereinigtem Montanwachs. Der Vorteil des Verfahrens liegt r. in der Verwendung technischen, wässerigen Ätznatrons gegenüber alkoholisch= @@tzallcali, 2. in dem Wegfall der vorherigen Auflösung in flüchtigen Lösungsmitteln. und 3. in dem Wegfall eines Emulgierungsmittels.The present process is now aimed at the production of montan wax soap from montan wax purified by a zinc chloride solution at elevated temperature. Of the The advantage of the procedure is r. in the use of technical, aqueous caustic soda opposite alcoholic = @@ tzallcali, 2. in the omission of the previous resolution in volatile solvents. and 3. in the elimination of an emulsifying agent.

Die Ausführung des Verfahrens geschieht derartig, daß man das durch Chlorzinklösung bei erhöhter Temperatur gereinigte Montanwachs möglichst fein, zweckmäßig auf einer kleinen Kugelmühle, zerkleinert. Zur vollständigen und glatten Verseifung muß möglichst jeder überflüssige Wässerzusatz bei der Verseifung vermieden werden. Zü diesem Zwecke stellt man aus dem zur Verseifung notwendigen 2oprozentigen Natriumhydroxyd unter Verwendung von .der geringsten Menge Wasser eine heiße, höchstkonzentrierte Natronlauge her. Die heiße konzentrierte Natronlauge wird zu dem im Kocher oder im Autoklaven befindlichen Montanwachs, :das inzwischen durch indirekten Heißdampf geschmolzen ist, zugegeben. Die Verseifung selbst erfolgt während etwa drei bis vier Stunden .durch überhitzten, indirekten Dampf im geschlossenen Autoklaven oder Kocher. Die Temperatur während des Kochprozesses hält man auf etwa r2o° C. Der Druck soll ungefähr 6 Atm. betragen. Nach Beendigung vier Verseifung wird der Druck durch Abblasen weggenommen und die gebildete Wachsseife in einer offenen, zweckmäßig indirekt beheizten Pfanne mit heißem Wasser unter beständigem Rühren zur Konsistenz eingedickt. .Zum Verbrauch wird diese Masse in irgendeinem Gefäß oder Behälter mit dem gleichen Volumen Wasser durch direkten Dampf zusammengeschmolzen, in heißem Wasser emulgiert und in kaltes. Wasser eingeleitet. Die hierbei sich ergebende Lösung läßt sich u. a. als Leim für die Papierfabrikation anwenden.The procedure is carried out in such a way that one can go through it Chlorine zinc solution Montan wax cleaned at elevated temperature as fine as possible, useful on a small ball mill, crushed. For complete and smooth saponification Any superfluous addition of water must be avoided during the saponification as far as possible. For this purpose, the 2% sodium hydroxide required for saponification is made using the smallest amount of water a hot, highly concentrated Caustic soda. The hot concentrated caustic soda becomes the one in the stove or Montan wax in the autoclave: meanwhile by means of indirect superheated steam melted, added. The saponification itself takes place for about three to four hours. by superheated, indirect steam in a closed autoclave or Stove. The temperature during the cooking process is kept at around r2o ° C. The pressure should be about 6 atm. be. After finishing four saponification, the pressure is through Blowing away and the wax soap formed in an open, expediently indirect heated pan with hot water, stirring constantly, thickened to a consistency. For consumption this mass is in any container or container with the same Volume of water melted together by direct steam, emulsified in hot water and in cold. Water introduced. The resulting solution can u. a. use as glue for paper production.
