Infrared spectroscopy and conformational analysis of poly(4-vinylpyridine) and its model compounds

Infrared spectroscopy and conformational analysis of poly(4-vinylpyridine) and its model compounds. Atvars, T. D. Z.; Dibbern, D. N.; Sabadini, E. (Inst. Quim., Univ. Estad. Campinas, Campinas, Brazil). 26222-40-2 and 2057-49-0 which are cas registry numbers are also used here. Spectrosc. Lett., 20(1), 1-15 (English) 1987. CODEN: SPLEBX. ISSN: 0038-7010. DOCUMENT TYPE: Journal CA Section: 36 (Physical Properties of Synthetic High Polymers) The IR spectrum of styrene-4-vinylpyridine copolymer [26222-40-2] was recorded at 4000 cm-1 to 400 cm-1. The vibrational assignments were compared with those of polystyrene and the model compds. 1,3-diphenylpropane [1081-75-0] and 4-(3-phenylpropyl)pyridine [2057-49-0]. The wavenumbers of the normal mode n16b of the arom. rings were used to establish the possible conformers of the polymer. .

On the role of sulfur compounds in coal liquefaction

On the role of sulfur compounds in coal liquefaction. Huang, C. B.; Stock, L. M. (Dep. Chem., Univ. Chicago, Chicago, IL 60637, USA). Prepr. Pap. - Am. Chem. Soc., Div. Fuel Chem., 27(3-4), 28-36 (English) 1982. CODEN: ACFPAI. ISSN: 0569-3772. DOCUMENT TYPE: Journal CA Section: 51 (Fossil Fuels, Derivatives, and Related Products) Section cross-reference(s): 25 S compds. that can yield thiols (e.g., PhCH2SPh [831-91-4]) catalyze D exchange between deuterated Tetralin [119-64-2] and Ph2CH2 [101-81-5], the decompn. of PhCH2CH2CH2Ph [1081-75-0], and the conversion of Illinois No. 6 coal to sol. products. Although certain metal sulfides (e.g., pyrite or pyrrhotite) may intervene directly with the org. compds. present in coals, indirect paths may be more significant. The results support the view that the S and H2S produced from the minerals in decompn. or redn. reactions accelerate the free radical processes essential for coal conversion. The reactivity of H2S appears to be enhanced in the presence of phenolic compds. which suggests in addn. that modest quantities of the sulfides may be converted to highly catalytically active thiols even under low-severity reaction conditions.
