Description
Herstellung von Emulsionen Es wurde gefunden, daß die Salze aus Harnstoff oder Thioharnstoff und ihren Ablrnmiingen, z.B. aus Guanidin, Alkylharnstoffen oder Alkylthioharnstoffen, und organischen Sulfonsäuren sich ausgezeichnet zur Herstellung von Emulsionen flüssiger Kohlenwasserstoffe eignen. Sie lösen sich ohne Zusatz eines Lösungsvermittlers z. B. in Mineralölen klar auf. Die Lösungen können mit Wasser beliebig verdünnt werden und geben dabei sehr beständige, schwach saure Emulsionen. Be nutzt man zur Verdünnung Lösungen von Natriumcarbonat, so erhält man je nach dessen Menge neutrale oder alkalische Emulsionen von großer Beständigkeit. Derartige Emulsionen können als Hilfsmittel in der Metallbearbeitung, z. B. als Bohröle, ferner als Schmälzmittel für Fasergut oder als Lederbehandlungsmitted verwendet werden.Preparation of emulsions It has been found that the salts from urea or thiourea and its derivatives, e.g. from guanidine, alkylureas or Alkylthioureas, and organic sulfonic acids are excellent for making of emulsions of liquid hydrocarbons. They come off without adding any Solubilizer z. B. clear in mineral oils. The solutions can be mixed with water can be diluted as required and give very stable, weakly acidic emulsions. If solutions of sodium carbonate are used for dilution, then depending on its quantity neutral or alkaline emulsions of great persistence. Such Emulsions can be used as auxiliaries in metalworking, e.g. B. as drilling oils, furthermore be used as a lubricant for fiber material or as leather treatment medium.
Beispiel Ein Gemisch aus fI Teilen einer im Kern mit einem höhermolekularen Alkylrest alkylierten Benzolsulfonsäure, 15,37 Teilen Harnstoff, 27 Teilen Wasser und 100 Teilen eines Mittelöls oder eines Mineralöls von ähnlichem Siedebereich wird 10 Minuten lang verrührt. Alsdann werden weitere 300 Teile des Mittelöls oder des Mineralöls zugegeben. Das Gemisch wird bis zur vollständigen Klärung, die nach etwa einer halben Stunde erreicht ist, gerührt. Es liefert beim Verdünnen mit Wasser eine sehr beständige Emulsion. Example A mixture of fI parts of a core with a higher molecular weight Alkyl radical alkylated benzenesulfonic acid, 15.37 parts of urea, 27 parts of water and 100 parts of a middle oil or a mineral oil of similar boiling range is stirred for 10 minutes. Then another 300 parts of the middle oil or of the mineral oil added. The mixture is left until it is completely clear about half an hour is reached, stirred. It delivers when diluted with water a very stable emulsion.
Man hat zwar schon Salze auls Oxalkylaminen mit organischen Sulfonsäuren zur Herstellung von Emulsionen vorgeschlagen. It is true that salts of oxyalkylamines with organic sulfonic acids have already been used proposed for the production of emulsions.
Die auf diese Weise hergestellten Emulsionen sind jedoch verhältnismäßig wenig beständig.However, the emulsions made in this way are proportionate not very stable.
Außerdem lösen sich die bekannten Salze in Mineralölen nicht ohne weiteres auf, so daß man hierzu eines Lösungsvermittlers bedarf. tm Gegensatz dazu lösen sich die oben beschriebenen Salze in Mineralölen ohne weileeres klar auf. Die beim Verdünnen mit Wasser erhaltenen Emulsionen sind sehr beständig und bleiben es auch bei sehr hoher Verdünnung.In addition, the known salts in mineral oils do not dissolve without them further, so that this requires a solubilizer. t in contrast to that The salts described above dissolve clearly in mineral oils without delay. The emulsions obtained on dilution with water are very stable and remain so even at very high dilutions.
