Least square analysis of the X-ray absorption near edge structure (XANES) region of sulfur K edge X-ray absorption fine structure (XAFS) spectra can provide a quantitative analysis of both the organic and inorganic functional forms of sulfur in coal.

A convenient method for the quantitative determination of elemental sulfur in coal is described. Elemental sulfur is extracted from the coal with hot perchloroethylene (PCE) (tetrachloroethene, C 2 Cl 4 ) and quantitatively determined by HPLC analysi

This paper summarizes efforts to increase the solubilities of coal fractions, with minimum loss of carbon, by oxidations with aqueous NaOCl, oxygen, and nitric acid, at or below 60 °C. The principal products were ‘black acids’, insoluble in wate

Ambient temperature air oxidation of coal (weathering) is a problem in storage, utilization, and characterization. This work grew out of our observations that toluene insoluble, pyridine soluble (TIPS) fractions of Illinois coals isolated by conventi

E and Z 2-phenylcyclopropyl bromides react with the title reagents to yield E and Z cinnamyl acetates respectively. No reaction is observed when halide nucleophiles or other aprotic solvents are used suggesting a novel mechanistic role for the acetat
