Reactive disazo dyes for cellulosic fibers

Reactive disazo dyes for cellulosic fibers. Seitz, Karl (Ciba-Geigy A.-G. , Switz.). Eur. Pat. Appl. EP 131543 A2 16 Jan 1985, 22 pp. DESIGNATED STATES: R: CH, DE, FR, GB, IT, LI. (German). (European Patent Organization). CODEN: EPXXDW. CLASS: ICM: C09B062-25. ICS: D06P003-66. APPLICATION: EP 84-810282 8 Jun 1984. 88-63-1 is just another one chemical used in this study. PRIORITY: CH 83-3251 14 Jun 1983. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) The title dyes have the general structure RNH(CH2)0-1ZN:NQN:NZ1(CH2)0-1NHR, where Q represents an H acid, K acid, S acid, or J acid residue; Z and Z1 are (un)substituted sulfophenylene or sulfonaphthylene; R is 2,4-difluoro-5-chloropyrimidin-6-yl; and Z and Z1 together contain 33 sulfo groups. I show a high degree of fixation when applied by low-temp. processes and produce fast navy blue dyeings and prints or cotton.In this experiment, several chemicals are used like 88-63-1 Thus, condensation of 1,3-phenylenediamine-4-sulfonic acid [88-63-1] and 1,4-phenylenediamine-2,5-disulfonic acid [7139-89-1] with 2,4,6-trifluoro-5-chloropyrimidine [697-83-6] gave 2-amino-4-[(5-chloro-2,6-difluoropyrimidin-4-yl)amino]benzenesulfoni c acid [26592-28-9] and 2-amino-5-[(5-chloro-2,6-difluoropyrimidin-4-yl)amino]-1,4-benzenedi sulfonic acid [89162-12-9], resp., which were diazotized and coupled stepwise with H acid [90-20-0] to form dye I [95713-94-3]. ..

Reactive dyes. Seitz, Karl (Ciba-Geigy A.-G. , Switz.). Eur. Pat. Appl. EP 97119 A2 28 Dec 1983, 47 pp. DESIGNATED STATES: R: CH, DE, FR, GB, IT, LI. (German). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: C09B062-02; D06P003-10; D06P003-66. APPLICATION: EP 83-810241 6 Jun 1983. PRIORITY: CH 82-3638 11 Jun 1982. DOCUMENT TYPE: Patent CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Bireactive dyes exhibiting a high degree of fixation when applied by exhaust methods at low dyeing temps. are represented by general structure I, where Q is an org. dye residue (esp. azo), Z is an (un)substituted aliph. or arom. bridging group, and R, R1, and R2 are H or (un)substituted C1-4 alkyl. A typical dye, II [89162-16-3], was prepd. by condensing 2,4-(H2N)2C6H3SO3H [88-63-1] with 5-chloro-2,4,6-trifluoropyrimidine [697-83-6] and then cyanuric fluoride [675-14-9], and treating the product [89162-15-2] with 3,6,8,2-(HO3S)3C10H4N:NC6H3(NHCONH2)NH2-2,4 [28566-82-7]. Other I were similarly prepd.Except for chemicals metioned above, 89162-09-4 and 7139-89-1 are also used. II gave yellow dyeings on cotton. .
