KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

KLASSEGREAT

Ersetzt man in dem Verfahren des Haupt-Patentes die dort genannten Phenole durch Phenolderivate, wie Amidophenole, Phenolcarbonsäuren u. s. w., so gelangt man in derselben Weise zu alkalilöslichen Condensationsprodukten. If the phenols mentioned there are replaced in the process of the main patent Phenol derivatives, such as amidophenols, phenol carboxylic acids and so on, are obtained in the same Way to alkali-soluble condensation products.

Beispiel I.Example I.

40 Th. C1 a4-Dinitronaphtalin in Pastenform werden unter Umrühren in eine auf ca. 95° erhitzte Lösung von 100 Th. Salicylsäure und 200 Th. cone. Natronlauge eingetragen. Nach beendigter Reaction wird mit Wasser verdünnt, mit Salzsäure sauer gemacht und das in braunen Flocken zugleich mit unveränderter Salicylsäure ausfallende Condensationsprodukt abgenutscht. Nach dem Trocknen wird dasselbe durch Extraction mit Aether von unverändert gebliebener 'Salicylsäure getrennt.40 Th. C 1 a 4 -Dinitronaphtalin in paste form with stirring in a heated to about 95 ° solution of 100 Th. Salicylic acid and 200 Th. Cone. Caustic soda entered. When the reaction is complete, it is diluted with water, made acidic with hydrochloric acid, and the condensation product, which precipitates in brown flakes with unchanged salicylic acid, is sucked off. After drying, it is separated from salicylic acid which has remained unchanged by extraction with ether.

Beispiel II.Example II.

436 Th. Ct1 Ct4-Dinitronaphtalin in Pastenform werden in eine 95 ° heifse Lösung von 202 Th. p-Amidophenol in 1200 Th. Natronlauge von 400B. und 1200 Th. Wasser unter Umrühren allmählich eingetragen. Nachdem noch ca. 1 Stunde die Temperatur auf 95 bis ioo° gehalten war, wird mit Wasser verdünnt und das Condensationsprodukt mit verdünnter Salzsäure ausgefällt.436 Th. Ct 1 Ct 4 -Dinitronaphtalin in paste form in a torrid 95 ° solution of 202 Th. P-amidophenol gradually added while stirring into 1200 Th. Sodium hydroxide solution of 40 0 B. and 1200 Th. Water. After the temperature had been kept at 95 to 100 ° for about 1 hour, it is diluted with water and the condensation product is precipitated with dilute hydrochloric acid.

In derselben Weise verhalten sich auch andere Phenolderivate, z. B. p-Amidosalicylsäure.Other phenol derivatives behave in the same way, e.g. B. p-Amidosalicylic acid.

Die Körper sollen als Ausgangsmaterialien zur Herstellung von Farbstoffen dienen. So liefert z. B. das p-Amidophenolcondensationsprodukt mit Polysulfid und Chlorzink verschmolzen ein Schwarz, das Condensationsprodukt aus ρ-Amidosalicylsäure ' ein Braun. Die sonstigen Eigenschaften ergeben sich aus folgender Tabelle: .The bodies are supposed to serve as starting materials for the production of dyes. So delivers z. B. fused the p-amidophenol condensation product with polysulfide and zinc chloride a black, the condensation product from ρ-amidosalicylic acid 'a brown. The other properties result from the following table:.
