The analysis of nonvolatile coal-derived liquefaction products for minor and trace components which contain nitrogen, oxygen or sulfur presents unique challenges. Justification for their analysis rests on the premise that heteroatom-containing materials can aid and/or hinder the conversion process. This proposal builds upon our efforts during the initial three year grant period regarding the interfacing of Fourier transform infrared spectrometry with size exclusion and normal phase chromatography for the analysis of coal-derived products. Four objectives are proposed: (1) optimize the HPLC-FTIR interface in terms of detectability, identifiability and chromatography, (2) extend the HPLC-FTIR approach to reversed phase chromatography wherein more efficient separations are possible for heteroatom species, (3) determine the feasibility of interfacing supercritical fluid chromatography with FTIR for the analysis of coal-derived products and (4) employ hyphenated methods to ascertain on a molecular level the changes that occur in a nonvolatile coal derived product when various liquefaction parameters are varied. This quarterly report describes the separation of several metal-containing systems using supercritical fluid chromatography. Packed, analytical scale chromatographic columns have been employed using supercritical methanol modified CO/sub 2/ as the mobile phase. 20 refs., 9 figs.
