Abstract

The room-temperature phosphorescence (r.t.p.) and fluorescence spectra of benzoquinoline isomers are investigated. The isomers can be resolved into the linear or angular subgroups on the basis of their fluorescence and r.t.p. spectra by using conventional fixed excitation. Second-derivative and synchronous scanning techniques can be combined to improve the selectivity of the r.t.p. and fluorescence methods. These simple luminescence techniques were used to estimate three benzoquinoline isomers in a coal tar fraction. Direct analysis of this complex sample allowed acridine to be estimated and upper limits to be provided for benzo(h)quinoline and phenanthridine; the presence of three other isomers was not detected. Comparative studies with data obtained by high-performance liquid chromatography are reported.

Recent advances in characterization technology for value-added utilization of coal tars

FSS wavelengths of some CAs are shown in Table 6 [107,108]. Notably, PSS and FSS studies of 8 benzoquinoline isomers in CT distillate at room temperature proved feasible by comparing HPLC and GC/MS (Table 7) [109]. Benzoquinoline isomers can be identified and semi-quantified based on their luminescence properties.
Coal tars are by products from coal pyrolysis, carbonization, and gasification, and are raw materials for obtaining value-added chemicals and carbon materials. Molecular characterization and identification of structural information and properties of coal tars are of great significance for effectively utilizing coal tars. This paper mainly elaborated on the sources of coal tars, the compound types in coal tar, the non-mass spectrometric and mass spectrometric characterization of coal tars, and the performance evaluation of coal tar pitch-based carbon materials. We hope that this review will contribute to the enthusiasm for investigating the value-added utilization of coal tars.
Laser-induced site-selection matrix-isolation fluorescence spectrometry of dibenzacridine isomers
1989, Talanta
Laser-induced matrix-isolation site-selection fluorescence spectrometry is used to obtain narrowed-line spectra, linear dynamic ranges and limits of detection for four isomeric dibenzacridines in argon at 15 K. Site-selection fluorescence is used to determine dibenzacridines in two synthetic mixtures, a four-component mixture of the isomeric dibenzacridines and a thirteen-component polycyclic aromatic hydrocarbon mixture. The capabilities of site-selection and Shpol'skii fluorescence spectrometry for the identification and determination of aza-arenes in complex mixtures are compared.
Identification of some polycyclic nitrogen-containing compounds in coal-derived oil
1986, Journal of Chromatography A
A systematic method for the identification of aza-arenes in coal-derived oil was developed. The basic nitrogen-containing substances were extracted with 6 M hydrochloric acid and fractionated sequentially by using gel chromatography and thin-layer chromatography (TLC) on an alumina plate. The aza-arenes in these fractions were separated by using glass capillary gas chromatography. Individual compounds in the column effluent were trapped in a system consisting of a valve for flow switching and a trapping tube made from a glass capillary. The fluorescence spectra of nanogram to subnanogram amounts of trapped compounds were measured. Some attempts were made to identify components based on their TLC R_F values and their fluorescence spectra, in addition to their mass spectra.
