Some insight into the chemical nature of coals and the coalification process was obtained by detailed analyses of the organic constituents of three coals — a lignite, a bituminous, and an anthracite coal. Organic compounds trapped in the coal matri

A crown-gall tumor growth factor (TGF-II) isolated from bean leaves inoculated with Agrobacterium tumefaciens strain 13333 is shown to be γ-aminobutyric acid (GABA). This identification is based on the comparative behavior of purified TGF-II and aut

Fluorination of bituminous coal by elemental fluorine yields a solid product from which a solid distillate can be made by vacuum pyrolysis. Both fluorinated materials are easily made and are useful for mass spectrometric unit mass assignments. They h

The previously described method for estimating aromaticity by fluorination has been applied to coals of various ranks and used to compare the aromaticity of a solvent-refined coal with that of the feed coal from which it was derived. Coals of various

Molecular fluorine has been used for the study of coal and a small number of model compounds. It is shown that direct estimates can be made of the carbon aromaticity and of the sensitive carbon in cyclic form. The value for a high-volatile Illinois b

This study reports the results from the oxidation, using sodium dichromate, of a solvent-refined lignite (SRL) and its feed coal and the effects of varying the ratio of oxidant to coal. The numerous aromatic and heteroaromatic carboxylic acids isolat

Degradation techniques, including pyrolysis, depolymerization, and oxidation, were used to study the insoluble polymer from the Murchison C2 chondrite. Oxidation with Cr2O7(2-) or O2/UV led to the identification of 15 aromatic ring systems. Of 11 ali
