Identification of nonvolatile coal derived products via chromatography coupled with on-line FTIR detection. Quarterly progress report, September 1-November 30, 1985

Technical Report ·
OSTI ID:5869966
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 separation 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. The primary objective of this project was to continue the development of an interface device for the coupling of reversed phase liquid chromatographic separations with Fourier Transform Infrared detection. 2 refs., 11 figs.
