 reinigungen und gleichzeitig   eine genügende Verdunstungsgeschwindigkeit besitzen   und weil sie meistens auf den gereinigten Textilien Ränder erzeugen und ihr Geruch denselben lange anhaftet. Es hat sich nun gezeigt, dass diese Übplstände vermieden werden, wenn man als   Fleckenentfernungsmittel   Dichlormethylen allein oder zweckmässig in Mischung mit anderen Lösungsmitteln benutzt. Insbesondere eignet sich ein Zusatz von Alkohol, da man Dichlorethylen fast 25% Alkohol zusetzen kann, ohne seine Nichtbrennbarkeit zu vermindern, hiedurch aber sein Lösungsvermögen für verschiedene Verunreinigungen, insbesondere solche   harzartiger Natur, erhöht   wird.

   Ebenso kann man dem Dichlorethylen erhebliche Mengen anderer brennbarer Lösungsmittel, ja selbst Benzin, zusetzen, ohne dass das Gemisch brennbar wird, so dass man z. B. ein sehr stark wirkendes, nicht   feuergefährliches   Fleckwasser aus Dichlorethylen durch gleichzeitigen Zusatz von Alkohol und Benzin erzeugen kann. 



   Ferner kann man das Dichlorethylen mit anderen bereits gebräuchlichen   unbrennbaren   oder wenig brennbaren Fleekenentfernungsmitteln mischen und hiedurch deren Siedepunkt herabsetzen,   d.   h. ihre Verdunstungsgeschwindigkeit und vor allen Dingen ihre Wirksamkeit erhöhen. Diese Erhöhung der Wirksamkeit beruht darauf, dass Dichlorethylen insbesondere in Gegenwart von Alkohol ein so hohes Lösungsvermögen für bisher als schwer   löslich   bekannte Substanzen wie z. B. die Hartharze besitzt, wie kein anderes   gebräuchliehes Lösungsmittel. Auch dem Tetrachlorkohlenstoff, welcher   ja bekanntlich ein sehr grosses Fettlösungsvermögen besitzt, ist Methylenchlorid weit überlegen, wie aus der beiliegenden tabellarischen Übersicht hervorgeht. 



   Methylenchlorid bildet infolgedessen ein ideales Lösungs-und Extraktions-und damit auch Ent-   fernungsmittel   von Fetten, Olen, Harzen und Substanzen aller Art, für welche bisher Benzin, Äther, Benzol, Alkohol, Azeton oder ähnliche Produkte als brennbare und chlorierte Kohlenwasserstoffe als unbrenn-

 EMI1.1
 cleaning and at the same time have a sufficient rate of evaporation and because they usually create edges on the cleaned textiles and their smell adheres to the same for a long time. It has now been shown that these inconveniences are avoided if dichloromethylene is used as the stain remover alone or advantageously mixed with other solvents. The addition of alcohol is particularly suitable, since almost 25% alcohol can be added to dichloroethylene without reducing its non-combustibility, but this increases its dissolving power for various impurities, especially those of a resinous nature.

   Likewise, you can add significant amounts of other flammable solvents, even gasoline, to the dichloroethylene without the mixture becoming flammable. B. can produce a very strong, non-flammable stain water from dichloroethylene by the simultaneous addition of alcohol and gasoline.



   Furthermore, the dichloroethylene can be mixed with other non-flammable or less flammable stain-removing agents that are already in use and thereby lower their boiling point, i. H. increase their evaporation rate and, above all, their effectiveness. This increase in effectiveness is based on the fact that dichloroethylene, especially in the presence of alcohol, has such a high dissolving power for substances previously known to be sparingly soluble, such as. B. has hard resins like no other common solvent. Methylene chloride is also far superior to carbon tetrachloride, which is known to have a very high fat-dissolving power, as can be seen from the accompanying table.



   As a result, methylene chloride forms an ideal solvent and extraction agent and thus also a means of removing fats, oils, resins and substances of all kinds for which gasoline, ether, benzene, alcohol, acetone or similar products were previously used as flammable and chlorinated hydrocarbons as non-flammable.
 EMI1.2
 Incombustibility, its extremely high dissolving power and its high evaporation rate.
