Sanitary-hygienic evaluation of a new industrial process for the production of brown vat dye: Sanitary-hygienic evaluation of a new industrial process for the production of brown vat dye. Doloman, N. I.; Chumachenko, A.In this study， 2475-33-4 and 128-95-0 are also used. A.; Momot, L. M.; Khokhlova, T. N. (Gorodskaya Sanepidstants., Rubezhnoe, USSR). Gig. Tr.

DOCUMENT TYPE: Journal CA Section: 40 (Dyes, Fluorescent Whitening Agents, and Photosensitizers) Section cross-reference(s): 59 Vat Brown SK (I) [2475-33-4] is prepd. by heating a dry mixt. of 1-chloroanthraquinone [82-44-0] and the leuco deriv. of 1,4-diaminoanthraquinone [128-95-0] in the presence of Cu powder with subsequent fusion in KOH and NaOAc. The old process required the use of solvents and AlCl3. The new fusion method is superior to the old in that fewer steps are required, solvents are not used, and air pollution by PhNO2, pyridine, and HCl is avoided. .
