The fate of nitrogenous model process solvents in coal liquefaction: The fate of nitrogenous model process solvents in coal liquefaction. Hellgeth, J. W.; Amateis, P. G.; Taylor, L. T. (Dep. Chem., Virginia Polytech. Inst. and State Univ., Blacksburg, VA 24061, USA). Prepr. Pap. - Am. Chem. Soc., Div. Fuel Chem., 29(5), 99-105 (English) 1984. CODEN: ACFPAI. ISSN: 0569-3772. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) In bituminous coal liquefaction in 1-methylnaphthalene (I) [90-12-0], Tetralin [119-64-2], 1,2,3,4-tetrahydroquinoline [635-46-1], 2,3-cyclohexenopyridine [10500-57-9], 1,2,3,4-tetrahydroisoquinoline [91-21-4], 1-methyl-2,3,4-trihydroquinoline [491-34-9], or quinoline [91-22-5], conversion to pyridine-sols. is dependent on the presence of readily donatable H. Conversion to MePh-sols. is weakly dependent on the presence of N; the effect is increased when the N is accompanied by donatable H. The only reaction with a net increase in distillate recovery was that with I. Some (10-15%) solvent incorporation was obsd. into the residue or cracked to light ends, which accounts for the redn. in distillate recovery.

Determination of aqueous chlorination reaction products of polynuclear aromatic hydrocarbons by reversed phase high performance liquid chromatography-gas chromatography: Determination of aqueous chlorination reaction products of polynuclear aromatic hydrocarbons by reversed phase high performance liquid chromatography-gas chromatography. Oyler, A. R.; Bodenner, D. L.; Welch, K. J.; Liukkonen, R. J.; Carlson, R. M.; Kopperman, H. L.; Caple, R. (Dep. Chem., Univ. Minnesota, Duluth, Minn., USA). Anal. Chem., 50(7), 837-42 (English) 1978. 84-65-1 which is the cas registry number is also used here. CODEN: ANCHAM. ISSN: 0003-2700. DOCUMENT TYPE: Journal CA Section: 61 (Water) Section cross-reference(s): 80 A convenient procedure is described for the quantitation of polynuclear arom. hydrocarbons (PAH) in water at the ng-mg/L level. The procedure involves forcing an aq. sample through a glass microfiber filter connected in series with a 7 ′ 50 mm C-18 high performance liq. chromatog. (HPLC) column. The HPLC column contg. the PAH material is then attached to a C-18 micropacked reverse-phase setup and eluted with an acetonitrile-water gradient. Fractions corresponding to each UV peak are collected and these aq.-acetonitrile fractions are then injected directly into a gas chromatograph equipped with a photoionization detector. Application of this procedure to the study of aq. chlorination reactions of several polynuclear arom. hydrocarbons is described. Anthraquinone [84-65-1], a chlorohydrin of fluoranthene, and a monochloro deriv. of fluorene, phenanthrene [85-01-8], 1-methylphenanthrene [832-69-9], and 1-methylnaphthalene [90-12-0] were identified and quantitated.Some commonly used reagents like 84-65-1 is used in this experiment. ..
