Carbon-13 NMR spectra of anthraquinone-derived dyes

Carbon-13 NMR spectra of anthraquinone-derived dyes. Rubin, I. B.; Buchanan, M. V. (Anal. Chem. Div., Oak Ridge Natl. Lab., Oak Ridge, TN 37831, USA). Magn. Reson. Chem., 23(3), 161-5 (English) 1985. CODEN: MRCHEG. ISSN: 0749-1581. DOCUMENT TYPE: Journal CA Section: 41 (Dyes, Organic Pigments, Fluorescent Brighteners, and Photographic Sensitizers) Section cross-reference(s): 77 The 13C NMR spectra of six anthraquinone-derived dyes, namely benzanthrone [82-05-3], 1-(methylamino)anthraquinone [82-38-2], 1,4-di-p-toluidinoanthraquinone [128-80-3], 1,4-diamino-2,3-dihydroanthraquinone [81-63-0], 1,4-diaminoanthraquinone [128-95-0], and dibenzo[b,def]chrysene-7,14-dione [128-66-5] were measured. The chem. shift assignments were achieved by elucidation of the coupling patterns of the fully coupled spectra and by comparison with the chem. shifts of other anthraquinone derivs. and other model compds. One- and three-bond C-H coupling consts. are also reported.

Chemical characterization and toxicologic evaluation of airborne mixtures: chemical characterization of combusted inventory red and violet smoke mixes

Chemical characterization and toxicologic evaluation of airborne mixtures: chemical characterization of combusted inventory red and violet smoke mixes. Rubin, I. B.; Buchanan, M. V.; Moneyhun, J. H. (Oak Ridge Natl. Lab.Some commonly used reagents like 128-95-0 and 82-45-1 are used in this experiment., Oak Ridge, TN, USA). Report, ORNL/TM-8810; Order No. DE83016429, 43 pp. Avail. NTIS From: Energy Res. Abstr. 1983, 8(20), Abstr. No. 49835 (English) 1982. DOCUMENT TYPE: Report CA Section: 4 (Toxicology) Red and violet smoke grenades (Grenade, Hand, Smoke, M18) were combusted within canvas tents and the combustion products were sampled and analyzed. Uncombusted red and violet smoke mixes from the same lots used to fill the combusted grenades were also analyzed. Approx. 10% of the major dye component of the red smoke mix, 1-methylaminoanthraquinone (MAA) [82-38-2], was converted to aminoanthraquinones (1-AA [82-45-1] and 2-AA [117-79-3]). The violet smoke mix was formulated to contain 1,4-diamino-2,3-dihydroanthraquinone (DAA) [81-63-0] and MAA. Upon combustion, the DAA was converted almost completely to 1,4-diaminoanthraquinone [128-95-0] which was a minor constituent of the uncombusted mix. As in the combusted red smoke mix, MAA was partially converted to aminoanthraquinones. .
