Description
Färben von Kohlenwasserstoffen Für Zwecke der Kennzeichnung werden Benzin, Petroleum und sonstige Kolilenwasserstoffe in verschiedenen Tönen angefärbt. Man hat hierfür bereits Dialkylaminoatitllracliinone vorgeschlagen. Es bestellt jedoch das Bedürfnis nach Farbstoffen, welche noch leichter löslich sind und infolgedessen die Herstellung einer konzentrierteren Stammlösung gestatten bzw. sich noch schneller in den zu kennzeichnenden Kohlenwasserstoff auflösen. Es wurde nun gefunden, daß die Di-(isoalkylamino)-anthrachinone sich durch eine besonders gute Löslichkeit auszeichnen und in dieser Beziehung die entsprechenden n-Alkylaminoverbindungen erlieblich übertreffen.Coloring of hydrocarbons for labeling purposes Petrol, kerosene and other hydrocarbons colored in different tones. Dialkylaminoatitllracliinones have already been proposed for this purpose. It ordered however, the need for dyes which are even more soluble and consequently allow the preparation of a more concentrated stock solution or even faster Dissolve in the hydrocarbon to be labeled. It has now been found that the di- (isoalkylamino) anthraquinones are characterized by particularly good solubility and in this respect the corresponding n-alkylamino compounds surpassable.
Gegenstand vorliegender Erfindung ist daher die Verwendung dieser Stoffe, und zwar vorzugsweise der 1, 4-, 1, 5- und i, 8-Verbindungen an sich oder in :Mischung untereinander oder in Mischung mit anderen Farbstoffen zum Färben von Kohlenwasserstoffen. Die genannten Verbindungen können nach an sich bekannten Methoden hergestellt werden, z. B. die i, 4-Diaminoverbindungen aus i, 4-Dioxyanthrachinon oder 1, 4-Dileukoaminoantlirachinon und die i, 5- bzw. i, 8-Diaminoverbindungen aus den entsprechenden Dinitroverbindungen. Um einen Eindruck von der verbesserten Läslichkeit zu geben, sei bemerkt, daB im Fall der 1,4-Diaminoverbindungen in i 1ßenzin (Siedepunkt über 80°) 3"4g des Dibutylaminofarbstoffs gegenüber 23 g des Diisobutylaminofarbstoffs löslich sind. Im Fall der i, 5-Diaminoverbindungen beträgt das Verhältnis 3,9 9 zu 6,6 g und im Fall der i, 8@D;i-n-propyl- bzw. Di-iso-propylaminoanthra-Chinone 2,8 g zu 5,0 g.The present invention therefore relates to the use of these substances, preferably the 1, 4-, 1, 5- and i, 8-compounds per se or as a mixture with one another or as a mixture with other dyes for dyeing hydrocarbons. The compounds mentioned can be prepared by methods known per se, e.g. B. the i, 4-diamino compounds from i, 4-dioxyanthraquinone or 1, 4-dileucoaminoantlirachinon and the i, 5- or i, 8-diamino compounds from the corresponding dinitro compounds. In order to give an impression of the improved solubility, it should be noted that in the case of the 1,4-diamino compounds in i-benzine (boiling point above 80 °) 3 "4 g of the dibutylamino dye are soluble compared to 23 g of the diisobutylamino dye -Diamino compounds is the ratio 3.9 9 to 6.6 g and in the case of the i, 8 @ D; in-propyl- or di-iso-propylaminoanthra-quinones 2.8 g to 5.0 g.
