Study of conversions of aromatic hydrocarbons to coke as illustrated by copyrolysis of anthracene and phenanthrene: Study of conversions of aromatic hydrocarbons to coke as illustrated by copyrolysis of anthracene and phenanthrene. Jastrzebski, Jerzy; Kubica, Krystyna; Stompel, Zygmunt (Inst. Chem. Przerobki Wegla, Zabrze, Pol.). Koks, Smola, Gaz, 29(3), 55-9 (Polish) 1984. CODEN: KSMGAA. ISSN: 0023-2823. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 22 The carbonization of anthracene (I) [120-12-7] is inhibited by phenanthrene (II) [85-01-8]. At 525°, II reacts with the transient 9-anthryl radical to give relatively unreactive 9-phenanthrylanthracene [91586-10-6] instead of the reactive 9,9'-bianthryl [1055-23-8]. Such reactions occur in the coking of coal. At 525°, the conversion of I alone to polymeric carbonaceous matter is ~90%; the conversion of II alone at 525° is ~4%. The conversions of I-II mixts. at 525° are 81 and 50%.

Effect of high pressure on intramolecular electron-transfer luminescence of 9,9'-bianthryl in different solvents: Effect of high pressure on intramolecular electron-transfer luminescence of 9,9'-bianthryl in different solvents. Hara, Kimihiko; Arase, Takuya; Osugi, Jiro (Fac. Sci., Kyoto Univ., Kyoto 606, Japan). J. Am. Chem.There are some reagents with their cas registry numbers 60-29-7 and 1055-23-8 are used in this study. Soc., 106(7), 1968-72 (English) 1984. CODEN: JACSAT. ISSN: 0002-7863. DOCUMENT TYPE: Journal CA Section: 73 (Optical, Electron, and Mass Spectroscopy and Other Related Properties) The effects of high pressure on the fluorescence from the intramol. electron-transfer state of 9,9'-bianthryl were investigated in different solvents. In low-viscosity solvents an increase of pressure affects the emission similarly to an increase of solvent polarity. In moderately viscous solvents the formation of the electron-transfer state is quenched as pressure is increased. In highly viscous solvents, as in glycerol, the emission is only from the locally excited state at atm. pressure, and no change except for peak shift is obsd. with pressure increase. Freezing of solvents at high pressure strictly quenches the formation of the electron-transfer state. .
