Die mit diesem Produkt erhaltenen Farblacke weisen wesentliche technische Vorzüge vor denjenigen Produkten auf, die aus dem isomeren i-Amino-2-methyl-5-nitrobenzolThe colored lakes obtained with this product have significant technical advantages before those products that are derived from the isomeric i-amino-2-methyl-5-nitrobenzene

durch Kombination mit ß-Naphtol erhalten werden und die in Heumann, »Anilinfarben«, 4. Band, I. Hälfte, 1903, S. 1000 bis 1002 erwähnt sind. Während die letzteren Lacke stumpf und mehr orange gefärbt sind, sind 45 can be obtained by combination with ß-naphtol and which are mentioned in Heumann, "Anilinfarben", 4th volume, I. half, 1903, pp. 1000 to 1002. While the latter varnishes are dull and more orange in color, 45 are
die aus dem neuen Farbstoff erhaltenen Lacke durch eine sehr klare, lebhafte und ausgesprochen rote Nuance ausgezeichnet. Dazu kommt noch, daß das bekannte Produkt stark öllöslich ist, während der neue Farbstoff und die aus ihm hergestellten Lacke vollkommen ölunlöslich sind.the varnishes obtained from the new dye by a very clear, lively and pronounced red shade excellent. In addition, the well-known product is strong is oil-soluble, while the new dye and the paints made from it are completely are insoluble in oil.
15,2 Teile i-Amino-2-methyl-4-nitrobenzol werden in 60 Teilen Salzsäure von 120 Be. und 30 Teilen Wasser unter Erwärmen gelöst; die Lösung wird auf Eis gegossen; die Diazotierung erfolgt, indem man 7 Teile Natriumnitrit, gelöst in Wasser, auf einmal zugibt und einige Zeit rührt. Die filtrierte Diazolösung läßt man alsdann in eine Suspension von 15 Teilen fein verteiltem ß-Naphtol einfließen und führt die Kombination durch Neutralisation mit Soda zu Ende. Der ausgeschiedene Farbstoff wird filtriert und gewaschen und kann entweder unmittelbar als Paste verwendet oder getrocknet werden.15.2 parts of i-amino-2-methyl-4-nitrobenzene are dissolved in 60 parts of hydrochloric acid of 12 ° Be. and 30 parts of water dissolved with heating; the solution is poured onto ice; the diazotization takes place by adding 7 parts of sodium nitrite, dissolved in water, all at once and stirring for some time. The filtered diazo solution is then allowed to flow into a suspension of 15 parts of finely divided β-naphthol and the combination is completed by neutralization with soda. The precipitated dye is filtered and washed and can either be used immediately as a paste or dried.
Die Darstellung des Farbstoffs kann natürlich auch in Gegenwart eines zur Herstellung von Lacken geeigneten Substrats erfolgen.The preparation of the dye can of course also be carried out in the presence of a preparation of paints suitable substrate.
