Vv. Platonov et al., Chemical composition of organic bases from semicoking tar of lignites fromthe near-Moscow fields, RUS J AP CH, 72(2), 1999, pp. 327-331
The chemical composition of organic bases from the semicoking tar of lignit
e from the near-Moscow fields was studied in detail by chemical functional,
emission spectrum, and structural-group analyses, LR, UV, and H-1 and C-13
NMR spectroscopy, cryoscopy, capillary gas chromatography, and chromatogra
phy-mass spectrometry. A scheme was developed for separation of the organic
bases by adsorption liquid chromatography.
