Heavy metal complexes: Heavy metal complexes. 91-35-0 which is the cas registry number of one of substances is just one of reagents here. Back, Gerhard; Fasciati, Alfred (Ciba-Geigy A.-G., Switz.). Ger. Offen. DE 2745024 13 Apr 1978, 106 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B005-14. PRIORITY: LU 76-75958 8 Oct 1976. 91-35-0 is just another one chemical used in this study. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Metal (Cu, Ni, Co, Cr) complexes are prepd. from monoazo compds. of general structure I, where R = H, Br, Cl, NO2, alkyl, alkoxy, or acylamino, R1 = H or alkyl, R2 = carboxy- or sulfo-substituted Ph or naphthyl, R3 = H or NH2, R4 = H, Cl, Br, CN, substituted or unsubstituted amino, SH, alkyl- or arylthio, sulfo, or arylsulfonyl, R5 = H, Cl, or Br, and n = 0 or 1. The complexes are fast dyes for wool and polyamide fibers. Thus, diazotization of 2-HO2CC6H4NHSO2C6H3(OH)NH2-4,3 [91-35-0], coupling with 2-amino-3-hydroxypyridine [16867-03-1], and treatment of the violet monoazo compd. (II) [66804-37-3] with CuSO4 gave the reddish violet to blue 1:1 Cu complex, a water-sol. powder dyeing polyamide fibers and wool fast blue shades. Approx. 60 other metal complex dyes were similarly prepd. ..

Mixture of 1:2 cobalt complex azo compounds: Mixture of 1:2 cobalt complex azo compounds. Uehlinger, Hanspeter (Sandoz-Patent-G.m.b.H., Switz.). Ger. Offen. DE 2729915 19 Jan 1978, 23 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B045-20. PRIORITY: CH 76-8903 12 Jul 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Mixts. of sym. and unsym. 1:2 Co complex azo dyes I(R = H; R1 = H, C1-4 alkyl; R2, R3 = H, halogen, C1-4 alkyl or alkoxy) and I (R = CO2H; R1, R2, R3 defined as in first dye) are prepd. and used to dye polyamide fibers fast reddish yellow shades. Thus, a mixt. of 2-amino-1-hydroxybenzene-4-sulfonic acid N-phenylamide [80-20-6] and 2-amino-1-hydroxybenzene-4-sulfonic acid N-phenylamide-2'-carboxylic acid [91-35-0] was dissolved in alkali, diazotized, coupled with acetoacetanilide [102-01-2], the azo dye mixt. I(R = R1 = R2 = R3 = H) (II) [65883-20-7] and I (R = CO2Na, R1 = R2 = R3 = H) (III) [65883-21-8] isolated, the mixt. treated with CoSO4, and salted to give a dye mixt. composed of II and III in equimolar ratio, sym. 1:2 Co complexes of II and III, and an unsym. 1:2 Co II-III complex.
