Description
Verfahren zur Herstellung wäßriger, kornloser Emulsionspasten aus Paraffinen Wäßrige Pasten (Emulsionen), die mit Paraffinen und Emulgatoren hergestellt werden, sind schon lange bekannt. So wird z. B. in der britischen Patentschrift 466 510 ein Verfahren beschrieben, gemäß welchem in einer 10%igen Harzseifenlösung Paraffin vom Schmelzpunkt 50° in Gegenwart von Wollfett, Montanwachs usw. durch ¾stündiges Kochen in eine Emulsion übergeführt wird. Wendet man dieses Verfahren aber auf die hochschmelzenden Paraffine aus der Benzins) nthese nach Fischer-Tropsch an, so zeigt es sich, daß keine beständige Emulsion erhalten wird, sondern der Kohlenwasserstoff sich beim Kaltrühren in körnigen Massen ausscheidet Diese seit weiniger Zeit in den Handel kommenden hochschmelzenden Paraffine, die bei der Benzinsynthese gewonnen werden, mit Schmelzpunkten von etwa 80 bis 100°, lassen sich nur schwierig bzw. gar nicht in der bisher üblichen Weise wäßrig emulgieren; ihre Emulsionen werden beim Erkalten der Masse bei etwa 60° körnig, was dann die Verwendung z. B. als Bohnermasse oder Schuhereme ausschließt.Process for the production of aqueous, grainless emulsion pastes from Paraffins Aqueous pastes (emulsions) made with paraffins and emulsifiers have been known for a long time. So z. B. British Patent 466 510 describes a method according to which in a 10% resin soap solution Paraffin with a melting point of 50 ° in the presence of wool fat, montan wax, etc. ¾hour boiling is converted into an emulsion. One applies this procedure but on the high-melting paraffins from the petrol thesis according to Fischer-Tropsch indicates that no permanent emulsion is obtained, but the hydrocarbon has been precipitated in granular masses during cold stirring for a short time the trade coming high-melting paraffins, which are obtained in the gasoline synthesis with melting points of around 80 to 100 °, can only be achieved with difficulty or do not emulsify in water in the usual way; their emulsions will be when the mass cools at about 60 ° grainy, what then the use z. B. as a polishing compound or excludes shoe memes.
Auch bei den sog. verseiften Emulsionen, die mit diesen Paraffinen hergestellt sind, zeigt sich der gleiche überstand, wenn sie im größeren Prozentsatz hierbei mitverwandt werden. Even with the so-called saponified emulsions made with these paraffins are produced, the same protrusion shows up when they are in the larger percentage be used here.
Es sei darauf hingewiesen, daß die Paraffine nach der Fischer-Tropsch-Synthese, obschon sie hochschmelzende Kohlenwasserstoffe sind, in chemischer Hinsicht mit den bisher üblichen Handelsparaffinen nicht in Parallele gebracht werden können; sie zeigen in mancher Hinsicht lein anderes Verhalten, so daß sich für die Handelsparaffine gültige Emulsionierungsverfahren ohne weiteres nicht auf diese neuen Produkte übertragen lassen. It should be noted that the paraffins according to the Fischer-Tropsch synthesis, although they are high-melting hydrocarbons, in chemical terms with the previously customary trade paraffins cannot be brought into parallels; in some respects they show no different behavior, so that for the trade paraffins valid emulsion processes are not easily transferred to these new products permit.
Es wurde nun gefunden, daß man kornlose, wäßrige Pasten auch mittels hochschmelzender, synthetischer Paraffine herstellen kann, wenn Wollfett in seinen verschiedenen Reinheitsgraden (Lanolin) oder Wollfettfettsäure, das Abfallprodukt bei der Lanolingewinnung, im genügenden Prozentsatz bei der Pastenherstellung mittels Montanwachs und der hochschmelzenden synthetischen Paraffine zugesetzt wird. Es ist hierbei aber wichtig, daß sowohl das Wollfett als auch das Montanwachs zusammen in der Schmelze vorhanden sein müssen, wenn eine kornlose Paste beim Verdünnen mit Wasser sich bilden soll; fehlt eines der Produkte, also entweder das Wollfett oder Montanwachs. dann scheidet sich das hochschmelzende Paraffin beim Erkalten der mit Wasser verdünnten Schmelze stets in körniger Form bei einer Temperatur in der Nähe von 605 ab und macht die Paste für Schuhcreme und Bohnermassen unverwendbar. It has now been found that grainless, aqueous pastes can also be used by means of High-melting, synthetic paraffins can be produced if wool fat is in its different degrees of purity (lanolin) or wool fatty acid, the Waste product from lanolin production, a sufficient percentage from paste production is added by means of montan wax and the high-melting synthetic paraffins. However, it is important here that both the wool fat and the montan wax go together Must be present in the melt when using a grainless paste when diluting with Water should form; one of the products is missing, either the wool fat or Montan wax. then the high-melting paraffin separates with the cooling down Water diluted melt always in granular form at a temperature close by from 605 and makes the paste unusable for shoe polish and floor polish.
Beispiel 60 Teile hochschmelzendes Paraffin werden unter Zusatz von 30 Teilen Rohmontanwachs und von 10 Teilen Wollfettfettsäure bei etwa 110C geschmolzen und anschließend 10 Teile Pottasche, gelöst in 30 Teilen heißem Wasser, langsam der Schmelze zugefügt. Unter starkem Schäumen (CO2-Entwicklung) bildet sich eine etwas dickere Schmelze, die bei weiterer Erwärmung gleichmäßig wird. Diese schwach alkalische Schmelze läßt sich nun durch Zusatz von heißem Wasser bei gutem Rühren und nachfolgender Abkühlung in eine gleichmäßige kornfreie Paste (Emulsion) verwandeln. Bei Zusatz von z.B. 200 Teiles heißem Wasser und kurzem Aufkochen entsteht zunächst eine dünne, milchige Lösung. Example 60 parts of high-melting paraffin are added with 30 parts of raw montan wax and 10 parts of wool fatty acid melted at about 110C and then slowly 10 parts of potash dissolved in 30 parts of hot water added to the melt. Under heavy foaming (CO2 development) one forms slightly thicker melt, which becomes even with further heating. This weak Alkaline melt can now be obtained by adding hot water while stirring well and then cool down into a uniform, grain-free paste (emulsion). If, for example, 200 parts of hot water are added and the mixture is brought to the boil briefly, the result is initially a thin, milky solution.
Dieselbe verdickt sich beim Erkalten unter Rühren zu einer steifen Paste, die sich dann durch weiteren Wasserzusatz leicht auf die gewünschte Konsistenz verdünnen läßt. Die Paste ist schwach bräunlich gefärbt. It thickens to a stiff when cooled while stirring Paste, which can then be easily adjusted to the desired consistency by adding more water can be diluted. The paste is slightly brown in color.
Der Zusatz von etwa IoO/o Wollfettfettsäure oder anderer Sorten Wollfett ist zur Herstellung dieser kernlosen Paste nach vorstehendem Beispiel unierläßlich, denn ohne diesen Zusatz erhält man beim Abkühlen der mit Wasser versetzten Schmelze zwar auch eine Paste, dieselbe ist jedoch ganz ungleichmäßig und mit härteren Körnern von ausgeschiediene Paraffin durchsetzt. The addition of about 10% wool fatty acid or other types of wool fat is indispensable for the production of this seedless paste according to the above example, because without this addition one obtains on cooling the melt mixed with water it is also a paste, but it is quite uneven and with harder grains interspersed with excreted paraffin.
Das erfindungsgemäße Verfahren führt die bei dem Fischer-Tropsch-Verfahren mitanfallenden Paraffine einem wichtigen Anwendungsgebiete zu. Bohnermassen und Schuhcremes sind so aus inländischen synthetischen Rohstoffen herstellbar. The process of the invention performs that in the Fischer-Tropsch process incidental paraffins to an important field of application. Floor polishes and Shoe polishes can thus be produced from domestic synthetic raw materials.
