Description
Zusatzpatent zum Hauptpatent Nr. 248603. Verfahren zur Herstellung eines metallisierbaren Disazofarbstoffes. Das vorliegende Patent betrifft ein Ver fahren zur Herstellung eines neuen metalli- sierbaren Disazofarbstoffes und ist dadurch gekennzeichnet, dass man 1 Mol tetrazotiertes 3,3'-Dioaxy-4,4'-diaminodiphenyl in Gegen wart von Pyridin mit 2 Mol 2-Oxynaph- tha-Iin-3,
6-disulfonsäure vereinigt. Beispiel: 3,88 Gewichtsteile 3,3' - Dioxy - 4,4' - di- a.minodiphenyl werden in etwa 27 Teilen Wasser und 10,8 Gewichtsteilen konz. Salz säure mit 2,48 Gewichtsteilen Natriumnitrit tetrazotiert. Die Tetrazosuspension wird mit Soda bei 0 kongoneutral gestellt und durch Filtration isoliert.
Der abgeschiedene Tetra.zo- körper wird in eine Lösung von 11,2 Ge- wichtsteilen 2 - Oxy naphthalin - 3, 6 - disulfon- säure, 80 Teilen. Wasser, 5 Gewichtsteilen Soda und 47 Gewichtsteilen Pyridin bei 2 eingetragen.
Es wird 1 Stunde bei 0-2 , 4 Stunden bei 10-15 , 30 Stunden bei 20 und am Schluss noch bei 35 gerührt, bis die Kupplung beendet ist. Der Farbstoff wird mit Salz abgeschieden und getrocknet.
Der neue Disazofarbstoff stellt ein schwarzes Pulver dar, welches sich in Wasser und in konzentrierter - Schwefelsäure mit blauer Farbe löst. Er färbt Zellwolle blau; die Färbung wird durch Behandlung mit Kupfersulfat lichtecht.
Additional patent to main patent No. 248603. Process for the production of a metallizable disazo dye. The present patent relates to a process for the production of a new metallizable disazo dye and is characterized in that 1 mol of tetrazotized 3,3'-dioaxy-4,4'-diaminodiphenyl in the presence of pyridine with 2 mol of 2-oxynaph- tha-Iin-3,
6-disulfonic acid combined. Example: 3.88 parts by weight of 3,3 '- dioxy - 4,4' - di- a.minodiphenyl are concentrated in about 27 parts of water and 10.8 parts by weight. Hydrochloric acid tetrazotized with 2.48 parts by weight of sodium nitrite. The tetrazo suspension is made Congo neutral with soda and isolated by filtration.
The deposited Tetra.zobody is in a solution of 11.2 parts by weight of 2 - oxynaphthalene - 3, 6 - disulfonic acid, 80 parts. Water, 5 parts by weight of soda and 47 parts by weight of pyridine entered at 2.
The mixture is stirred for 1 hour at 0-2, 4 hours at 10-15, 30 hours at 20 and finally at 35 until the coupling is complete. The dye is deposited with salt and dried.
The new disazo dye is a black powder that dissolves in water and in concentrated sulfuric acid with a blue color. He dyes rayon blue; the color becomes lightfast by treatment with copper sulphate.
