Description
<B>Zusatzpatent</B> zum Hauptpatent Nr. 106779. Verfahren zur Darstellung eines Küpenfar bstoffes. Es wurde gefunden, dass man einen neuen Küpenfarbstoff erhält, wenn man 5. 6-Benzo- 7-chlor-2. 3-diketodihydro-l-thionaphthen mit 1 Mol. Dichlorisatin kondensiert; der so ge wonnene neue Farbstoff bildet ein violettes' Pulver.
Er gibt, mit Hydrosulfit und Natron lauge erwärmt, eine braune Küpe, .die Baum wälle und Wolle in sehr echten, rotvioletten Tönen anfärbt. Die Kondensation lässt die in der Technik übliehen Verfahren zu.
Beispiel 240 Gewichtsteile 5. 6-Benzo-7-ehlor-2.3- cliketodihy dro-l-thionaplitlien und 216 Ge wichtsteile Dichlorisatin werden in Eisessig gelöst, mit etwas konzentrierter Salzsäure versetzt und eine Stunde lang unter Rühren auf 100 erhitzt, Der erhaltene Farbstoff wird abgesaugt-,- gewaschen und getrocknet; er bildet ein violettes Pulver, das aus der braunen Hydrosulfitküpe die Textilfaser in klaren, rotvioletten Tönen von hervorragen der Echtheit anfärbt.
<B> Additional patent </B> to main patent no. 106779. Process for the preparation of a vat dye. It has been found that a new vat dye is obtained if 5. 6-benzo-7-chloro-2. 3-diketodihydro-1-thionaphthene condensed with 1 mol. Dichlorisatin; the new dye obtained in this way forms a purple powder.
He gives a brown vat, warmed up with hydrosulfite and caustic soda, which dyes the tree walls and wool in very real, red-violet tones. The condensation allows the methods customary in technology.
Example 240 parts by weight of 5. 6-Benzo-7-ehlor-2,3-cliketodihy dro-l-thionaplitlien and 216 parts by weight of dichloroisatin are dissolved in glacial acetic acid, mixed with a little concentrated hydrochloric acid and heated to 100 for one hour while stirring. The dye obtained is vacuumed -, - washed and dried; it forms a violet powder which, from the brown hydrosulfite vat, dyes the textile fibers in clear, red-violet shades of excellent authenticity.
