Description
Verfahren zur Herstellung eines neuen Kondensationsproduktes. Es wurde gefunden, dass man zu neuen, wertvollen Kondensationsprodukten gelangen kann, wenn man halogenierte Naphthochinon- imide mit Ammoniak, Aminen, Phenolen oder Thiophenolen kondensiert.
Die als Ausgangsstoffe verwendeten halo- genierten Naphthochinonimide können z. B. nach dem Verfahren der Patentschrift Nr. 25.1646 hergestellt werden.
Die Kondensation dieser Ausgangspro dukte mit Ammoniak, Aminen, Phenolen oder Thiophenolen wird vorteilhafterweise in Ge genwart eines Lösungsmittels - wobei als solches auch -ein Überschuss der mit dem Ausgangsstoff zu kondensierenden Substanz verwendet werden kann - und in Gegenwart von Kondensationsbesehleunigerar., wie Bor säure, Kupfer oder Kupfersalzen usw., bei erhöhter Temperatur vorgenommen,
wobei ein oder mehrere Halogenatome der halogenier- ten Naphthochinonimide gegen die Radikale der zur Kondensation verwendeten Verbin dungen ausgetauscht werden. Bei Verwen dung von flüchtigen Aminen ist es angezeigt, die Kondensation in geschlossenen Gefässen und unter Druck durchzuführen.
Die so ge- wonn(enen neuen Kondensationsprodukte lösen sich in organischen Lösungsmitteln mit roter bis dunkelblauer Farbe und in konzentrierter Schwefelsäure mit gelber bis blauer Farbe auf und können durch Behandlung mit Re duktionsmitteln in die entsprechenden Leuko- oder Hydroverbindungen, die sich an der Luft wieder oxydieren, übergeführt werden. Sie sollen als Farbstoffe oder als. Ausgangs- produkte zur Herstellung von Farbstoffen dienen.
Die vorliegende Erfindung betrifft ein Verfahren zur Darstellung eines neuen Kon densationsproduktes und ist dadurch gekenn zeichnet, dass man das nach dem Verfahren gemäss Patentanspruch der Patentschrift Nr. 251646 erhältliche bromierte Naphtho- chinonimid mit Ammoniak kondensiert. <I>Beispiel:</I> 9 g des nach dem Beispiel der Pa tentschrift Nr. 251646 erhältlichen bromierten Naphthoehinonimids werden in 100 g Äthanol aufgeschwemmt und nach Zusatz von 5 cm' wässerigem Ammoniak 25 %, 2 g Natrium acetat und 0,1 g Kupferpulver unter Druck während 16 Stunden auf 90 erhitzt.
Nach dem Abdestillieren des Alkohols wird der Rückstand mit Wasser gewaschen und ge trocknet. Man erhält ein .dunkles Pulver, welches in Äthanol mit blauvioletter und in H-#S04 mit rötlichbrauner Farbe löslich ist, während das Ausgangsprodukt in Äthanol mit blauer und in H=SO,, mit olivebrauner Farbe löslich iet. Die neue Verbindung soll als Farbstoff für Acetatseide verwendet werden.
Process for the production of a new condensation product. It has been found that new, valuable condensation products can be obtained if halogenated naphthoquinone imides are condensed with ammonia, amines, phenols or thiophenols.
The halogenated naphthoquinonimides used as starting materials can, for. B. be prepared by the method of patent specification No. 25.1646.
The condensation of these starting products with ammonia, amines, phenols or thiophenols is advantageously carried out in the presence of a solvent - and an excess of the substance to be condensed with the starting material can be used as such - and in the presence of condensation accelerators, such as boric acid, Copper or copper salts, etc., made at elevated temperature,
one or more halogen atoms of the halogenated naphthoquinonimides being exchanged for the radicals of the compounds used for condensation. When using volatile amines, it is advisable to carry out the condensation in closed vessels and under pressure.
The new condensation products obtained in this way dissolve in organic solvents with a red to dark blue color and in concentrated sulfuric acid with a yellow to blue color They are intended to be used as dyes or as starting products for the production of dyes.
The present invention relates to a method for preparing a new condensation product and is characterized in that the brominated naphthoquinonimide obtainable by the method according to patent claim of patent specification No. 251646 is condensed with ammonia. <I> Example: </I> 9 g of the brominated naphthoehinonimide obtainable according to the example of patent specification No. 251646 are suspended in 100 g of ethanol and, after addition of 5 cm 'of aqueous ammonia, 25%, 2 g of sodium acetate and 0.1 g of copper powder heated to 90 under pressure for 16 hours.
After the alcohol has been distilled off, the residue is washed with water and dried. A dark powder is obtained which is soluble in ethanol with a blue-violet color and in H- # SO4 with a reddish-brown color, while the starting product is soluble in ethanol with a blue color and in H = SO ,, with an olive-brown color. The new compound is said to be used as a dye for acetate silk.
