Description
Behandelt man 3-Chlor-6-nitro-i-aminobenzol mit Formaldehyd, so erhält man ein Kondensationsprodukt, dem vermutlich die FormelIf 3-chloro-6-nitro-i-aminobenzene is treated with formaldehyde, a condensation product is obtained presumably the formula

Die Kondensation kann in der verschiedensten Weise, z. B. in Gegenwart von Alkohol, Wasser usw., vorgenommen werden.The condensation can take place in a variety of ways, e.g. B. in the presence of alcohol, water etc., can be made.
Es hat sich weiter gezeigt, daß sich dieses neue Kondensationsprodukt in hervorragender Weise zur Herstellung von Farblacken eignet. Die nach den bei der Pigmentfarbendarstellung üblichen Methoden daraus hergestellten Lacke zeichnen sich durch ihre hervorragend reine, bei Pigmentfarben bisher unerreichte, grünstichig gelbe Nuance sowie durch eine sehr gute Licht-, Wasser-, Kalk- und Spritechtheit aus.It has also been shown that this new condensation product is excellent Way suitable for the production of colored lacquers. The one after the pigment color representation Customary methods made from it are characterized by their excellent paints pure, greenish yellow shade previously unattainable in pigment colors, as well as through a very good fastness to light, water, lime and alcohol.
Im Patent 158543. sind bereits Formaldehydkondensationsprodukte aus Nitroanilinen und Nitrotoluidinen beschrieben, welche nach den dort gemachten Angaben ebenfalls zur Herstellung von Lacken Verwendung finden sollen.Formaldehyde condensation products are already in patent 158543. described from nitroanilines and nitrotoluidines, which, according to the information given there, also for production of paints should be used.
Von diesen unterscheiden sich die Lacke aus dem neuen Produkte in erster Linie durch ihre bedeutend klarere, reinere und grünstichigere Nuance sowie durch eine größere Lichtechtheit. ·The varnishes from the new products differ from these primarily through its significantly clearer, purer and greener shade as well as a larger one Lightfastness. ·
345 Teile einer 10 prozentigen Paste von 3-Chlor-6-nitro-i-aminobenzol werden mit 30 Teilen einer 30 prozentigen Formaldehydlösung versetzt und in einem geschlossenen Gefäße unter Rühren so lange auf 70 bis 8o° erwärmt, bis keine diazotierbare Substanz mehr nachzuweisen ist. Nach dem Erkalten wird abgesaugt, mit Wasser gewaschen und entweder bei gelinder Wärme getrocknet oder in Pastenform gebracht.345 parts of a 10 percent paste of 3-chloro-6-nitro-i-aminobenzene are mixed with 30 Parts of a 30 percent formaldehyde solution are added and placed in a closed vessel heated to 70 to 80 ° with stirring until no more diazotizable substance is to be proven. After cooling, it is suctioned off, washed with water and either Dried under mild heat or made into a paste.
Das so erhaltene intensiv gelb gefärbte Produkt ist unlöslich in Wasser und wenig löslich in den gebräuchlichen organischen Lo-. sungsmitteln.The intensely yellow colored product obtained in this way is insoluble in water and little soluble in common organic lo-. solvents.
