The preparative scale separation and the identification of constituents of anthraquinone-derived dye mixtures. Part 3. Products from the combustion of red and violet smoke mixtures. Rubin, I. B.; Buchanan, M. V.; Moneyhun, J. H. (Anal. Chem. Div., Oak Ridge Natl. Lab., Oak Ridge, TN 37830, USA). Anal. Chim. Acta, 155, 151-8 (English) 1983. CODEN: ACACAM. ISSN: 0003-2670. DOCUMENT TYPE: Journal CA Section: 50 (Propellants and Explosives) Section cross-reference(s): 41 Two colored-smoke grenades, red and violet, were detonated, and the particulate and vapor-phase portions were collected and analyzed. The original dye mixes were also analyzed for comparison. The CHCl3-sol. portion of each dye mix was fractionated by liq. chromatog. on silica gel, as was the original red dye mix, while the original violet smoke mix was fractionated by differential soly. Major components were collected in essentially pure fractions, while the impurities were concd. in other fractions. The dye portion of the red smoke mix was substantially unchanged on combustion, with the major component remaining as 1-methylaminoanthraquinone [82-38-2]. A significant amt. (>5%) of 1-aminoanthraquinone [82-45-1] was formed, however. The dye portion of the violet smoke mix was quant. converted from 1,4-diamino-2,3-dihydroanthraquinone [81-63-0] to 1,4-diaminoanthraquinone [128-95-0] upon combustion. The nonvolatile and(or) CHCl3-insol. portions consisted mainly of NaCl, KCl, elemental S, and undifferentiated carbonaceous matter. Major constituents of the vapor phases were CS2, toluene [108-88-3], C2-benzenes, styrene [100-42-5], chloromethylbenzene [25168-05-2], and naphthalene [91-20-3]. Aliph. and arom. hydrocarbons, alkylbenzenes, and thiophenes, as well as a no. of other compds.Except for chemicals metioned above, 82-38-2 is also used., were detected in smaller quantities. .

Sulfur- and chlorine-containing additives to lubricants

Sulfur- and chlorine-containing additives to lubricants. Balin, A. I.; Veretenova, T. N.Chemicals with cas numbers 10025-67-9 and 88403-86-5 also play role.; Tarasevich, V. B.; Kashtan, L. M. (VNIIPKneftekhim, USSR). Neftepererab. Neftekhim. (Moscow), (11), 19-21 (Russian) 1983. CODEN: NNNSAF. ISSN: 0028-1190. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 38 Antiwear and antiseize additives for lubricating oils were prepd. by treating PhCl [108-90-7] with S2Cl2 at 90° in the presence of Fe sulfide and then alkylating the remelted low mol.-wt. polysulfides with olefin fractions b. 140-180° or 240-320°. The products were oil-sol. and consisted of alkylated phenylene groups with -S- or -SS- bridges. Their structure was confirmed by comparison with S2Cl2- chlorotoluene [25168-05-2] condensation products. .
