Description
Verfahren zur Herstellung von Küpenfarbstoffen Durch das Patent 9i5 969 wird ein Verfahren zur Herstellung von Küpenfarbstoffen unter Schutz gestellt, das darin besteht, daß man 4-Amino-2, i-anthrachinon-4'-chlor-benzacridon der Formel mit in m-Stellung durch Halogen oder Alkoxy substituierten Benzoesäuren oder deren funktionellen Derivaten kondensiert.Process for the production of vat dyestuffs The patent 915969 places a process for the production of vat dyestuffs under protection, which consists in that 4-amino-2, i-anthraquinone-4'-chlorobenzacridone of the formula condensed with benzoic acids or their functional derivatives substituted by halogen or alkoxy in the m-position.
Es wurde nun gefunden, daß man gleichfalls wertvolle Küpenfarbstoffe erhält, wenn man das 4.-Amino-2, i-anthrachinon-4'-chlor-benzacridon mit o-halogensubstituierten Benzoesäuren oder deren funktionellen Derivaten, wobei der Benzolkern noch weitere Substituenten, insbesondere Halogen, enthalten kann, kondensiert.It has now been found that valuable vat dyes can also be obtained obtained when the 4th-amino-2, i-anthraquinone-4'-chloro-benzacridone with o-halogen-substituted Benzoic acids or their functional derivatives, with the benzene nucleus still further Substituents, in particular halogen, may contain, condensed.
Die so erhaltenen Farbstoffe färben Baumwolle in klaren blauvioletten Tönen wesentlich rotstickiger als die des Patents 915 969 und besitzen ebenso wie die des Hauptpatents gegenüber den dort genannten bekannten Farbstoffen überlegene Echtheitseigenschaften. Beispiel Ein Gemisch aus 7oo Teilen o-Dichiorbenzol, 38 Teilen 4-Amino-2, z-anthrachinon-4'-chlor-benzacridon und 42 Teilen 2, 4-Dichlorbenzoylchlorid wird z2 Stunden, auf 14o° erhitzt. Nach dem Erkalten wird der gebildete Farbstoff abgesaugt und zunächst mit o-Dichlorbenzol und dann mit Methanol ausgewaschen und getrocknet. Er färbt Baumwolle aus roter Küpenlösung in klaren blauvioletten Tönen von hervorragenden Echtheitseigenschaften.The dyes obtained in this way dye cotton a clear blue-violet Tones much redder than those of patent 915 969 and have the same as that of the main patent is superior to the known dyes mentioned there Authenticity properties. Example A mixture of 700 parts of o-dichiorobenzene, 38 parts of 4-amino-2, z-anthraquinone-4'-chlorobenzacridone and 42 parts of 2,4-dichlorobenzoyl chloride is heated to 14o ° for 2 hours. After cooling, the dye formed is suctioned off and washed first with o-dichlorobenzene and then with methanol and dried. He dyes cotton from red vat solution in clear blue-violet tones of excellent fastness properties.
Wird in dem obigen Beispiel das 2, 4-Dichlorbenzoylchlorid ersetzt durch eine entsprechende Menge von o-Chlor- oder 2, 5-Dichlorbenzoylchlorid, so werden Farbstoffe erhalten, die Baumwolle in ähnlicher Nuance und ähnlichen Echtheitseigenschaften färben wieder Farbstoff des Absatzes r dieses Beispiels.Is replaced in the above example, the 2,4-dichlorobenzoyl chloride by an appropriate amount of o-chlorine or 2, 5-dichlorobenzoyl chloride, so dyes are obtained, the cotton in a similar shade and similar fastness properties dye again dye of paragraph r of this example.
