Description
Verfahren zur Herstellung von Emulsionen Es ist bekannt, Öle und andere wasserunlösliche Stoffe durch Emulgatoren in Wasser zu emulgieren. Dazu benötigt man neben dem Stoff, der emulgiert werden soll, einen Emulgator, der, in kleinerer oder größerer Menge zugesetzt, die Emulsion hervorruft, dietdann mehr oder weniger beständig ist.Process for the production of emulsions It is known to oils and others to emulsify water-insoluble substances in water by means of emulsifiers. Needed for this one next to the substance that is to be emulsified, an emulsifier, the, in smaller or a larger amount added, which causes the emulsion, which then more or less is constant.
Es wurde nun gefunden, daß Abfallstoffe der Glykolherstellung aus Acetylen, beispielsweise das Polyprodukt GA,das im wesentlichen aus einer wäßrigen Lösung höherer Polyglykole besteht, hervorragende Emulsionen hervorrufen, wenn man sie durch Destillation in den wasserunlöslichen Zustand überführt. Bei der Emulgierung ist dann kein besonderer Emulgatorzusatz nötig. Die erhaltenen Emulsionen weisen eine außerordentlich lange Beständigkeit auf. It has now been found that waste materials from glycol production Acetylene, for example the poly product GA, which consists essentially of an aqueous Solution of higher polyglycols, produce excellent emulsions if one they are converted into the water-insoluble state by distillation. When emulsifying no special emulsifier addition is then necessary. The emulsions obtained have an extraordinarily long durability.
Im allgemeinen bleibt das Polyprodukt G A, das wasserlöslich ist, beim Erhitzen wasserlöslich. In general, the polyproduct G A, which is water-soluble, remains water soluble when heated.
Unterwirft man es aber der fraktionierten Destillation, so wird es wasserunlöslich. Wasserunlösliche Anteile im Polyprodukt, die in den wasserlöslichen Anteilen gelöst sein können, brauchen nicht mehr in den wasserunlöslichen Zustand übergeführt zu werden. Sie werden unmittelbar emulgiert.But if it is subjected to fractional distillation, it becomes insoluble in water. Water-insoluble fractions in the poly product, those in the water-soluble Fractions that can be dissolved no longer need to be in the water-insoluble state to be convicted. They are emulsified immediately.
Man kann bei der Emulgierung nun auch Ole zufügen oder andere, zu emulgierende Stoffe zusetzen bzw. bei Emulgierungen übliche Arbeitsweisen anwenden, etwa die Emulgierung aus praktischen oder w irtschaftlichen Gründen mit einer anderen Emulgierung, die in bekannter Weise mit einem Emulgator und einem zu emulgierenden Stoff durchgeführt wird, verbinden. You can now also add oils or others during emulsification add emulsifying substances or use the usual working methods for emulsification, for example emulsification with another for practical or economic reasons Emulsification, carried out in a known manner with an emulsifier and a substance to be emulsified will connect.
Polyprodukt GA wird fraktioniert Idestilliert Dabei fallen ii O/o einer Fraktion von 100 bis 1250 an, die hauptsächlich aus Wasser besteht. Von I80 bis 2200 destillieren r60/o über, bei 260 bis 300° die Hauptmenge von 650/0. Im Rückstand bleiben 16 bis I8°/o als Pech. Die Fraktion von 260 bis 3000 wird nun in einer Menge von 6 kg mit 94 1 Wasser ohne jede Vorsichtsmaßnahme, wie sie sonst bei der Herstellung von Emulsionen nötig ist, vermischt. Polyproduct GA is fractionated / distilled a fraction from 100 to 1250, which consists mainly of water. From I80 up to 2200 r60 / o distill over, at 260 to 300 ° the main amount of 650/0. in the 16 to 18% of the residue remains as pitch. The fraction from 260 to 3000 will now in an amount of 6 kg with 94 liters of water without any precautionary measures as otherwise in the production of emulsions is necessary, mixed.
Es entsteht eine haltbare Emulsion, die, gegebenenfalls unter Anwendung anderer, bei Emulgierungen üblicher Arbeitsweisen, beispielsweise zur Gewinnung von Schädlingsbekämpfungsmittei n nach Art der Mineralölspritzmittel oder des Obstbaumkarbolineums oder für andere Zwecke, etwa für Bohröle, Textilhilfsmittel, Waschhilfsstoffe und weitere Produkte, für die Emulsionen benutzt werden, Verwendung findet. The result is a long-lasting emulsion, which, if necessary, can be used other working methods customary for emulsifications, for example for extraction of pest control agents like mineral oil sprays or fruit tree carboline or for other purposes, for example for drilling oils, textile auxiliaries, washing auxiliaries and other products for which emulsions are used is used.
Die Emulsion hat einen pH-Wert von 7 bis 8, ebenso wie das Ausgangsmaterial. The emulsion has a pH of 7 to 8, just like the starting material.
Die bei der Destillation anfallenden Nebenprodukte werden zur Herstellung von Lösungsmitteln, Lacken und anderen Stoffen verwendet. The by-products resulting from the distillation are used for production used by solvents, paints and other substances.
Erhitzt man dagegen das Polyprodukt GA nur auf 2600, So bleibt es wasserlöslich und gibt keine Emulsion. Ebenso liefert das nichterhitzte Polyprodukt GA mit t)l keine Emulsion in Wasser, auch nicht mit 01, wenn es auf 260° erhitzt wird. If, on the other hand, the poly product GA is only heated to 2600, it stays that way soluble in water and does not emulsify. Likewise, the unheated poly product delivers GA with t) l no emulsion in water, not even with 01 when it is heated to 260 ° will.
