Separation and characterization of coal derived components, 1 July-30 September 1985. [Hydroxyl aromatics]

Technical Report ·
OSTI ID:5137327

The compositional data obtained from chloroform-soluble preasphaltenes of Kentucky 9/14 coal-derived SRC (F-51) has been evaluated and written in rough manuscript form. The low carbon content and low volatility for several fractions isolated from Wyodak coal-derived SRC (F-45) appears to be related to the iron content of the mobile phases used in conjunction with silica gel. A method has been developed for the separation of nitrogen compounds from oils and asphaltenes. The method involves the Chromasorb T-basic alumina procedure to obtian nitrogen rich fractions, removal of polycyclic aromatic hydrocarbons with silica gel, and separation of basic and nonbasic nitrogen compounds with a bonded-amino phase column. Finally, four manuscripts on various topics related to the project are being reviewed. The following two reports in the appendices have been processed separately for inclusion in the Energy Data Base: ''Separation of aromatic nitrogen compounds into compound-class types using normal-phase high performance liquid chromatography''; and ''Solvent composition effects in the normal-phase liquid chromatography of nitrogen heterocycles and hydroxyl aromatics on a nitrophenyl stationary phase''. 10 figs., 1 tab.
