Azo dyes: Azo dyes. Moells, Han Heinz; Schiwy, Willy; Hoernle, Reinhold; Nebeling, Reinhard (Bayer A.-G., Ger.). Ger. Offen. DE 2607122 25 Aug 1977, 25 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C09B041-00. APPLICATION: DE 76-2607122 21 Feb 1976. DOCUMENT TYPE: Patent CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Neg. substituted aniline derivs. are diazotized in the presence of a reaction product of a H2SO4, HCHO, and ditolyl ether [28299-41-4], biphenyl [92-52-4], or naphthalene [91-20-3], coupled with the desired coupler, neutralized with aq. NaOH, milled, and spray dried to give a azo dye compn. which is easily dispersible in H2O. Another related process which combines azo components and couples is described.

Sulfonated aromatic reaction products useful in tanning leather: Sulfonated aromatic reaction products useful in tanning leather. Wuermli, Albert (Ciba-Geigy A.-G., Switz.). Ger. Offen. DE 2717141 10 Nov 1977, 55 pp. (German). (Germany). CODEN: GWXXBX. CLASS: IC: C08G008-18. PRIORITY: CH 76-5046 22 Apr 1976. DOCUMENT TYPE: Patent CA Section: 41 (Leather and Related Materials) The title tanning materials comprised 100 parts sulfonated product from 10-90% Me-substituted di-Ph ether and 90-10% Me-substituted PhOH (1 mol of product) contg. 1-2 mols. sulfonating agent, e.g. H2SO4, and 1-6 parts HCHO, or 4-24 parts mixt. of an aminoplast and HCHO, or 4-24 parts aminoplast precondensate. Thus, 300 parts ditolyl ether [28299-41-4] and 500 parts PhOH [108-95-2] were mixed and sulfonated 3 h at 125-30° with 765 parts oleum, the sulfonated mixt. was heated 5 h at 160° and reduced pressure of 15 torr, 100 parts of the product was dissolved in 20 parts H2O, 5 parts of a 30% aq. HCHO soln. was added and heated 2 h at 80-5°, the condensate was dild. with 85 parts H2O and adjusted to pH 4.0 with 44 parts 25% aq. NH3 soln., and 6 parts 85% HCO2H were added to give 255 parts of a red-brown colored, clear, thin sirup contg. solids 43.7, tannins 27.4, and nontannins 16.3%.
