| Abstract: | A polymeric acid fraction has been isolated from Black Trona Water, a fossil water from the Green River Formation of Wyoming, by means of exhaustive dialysis. The polymeric acid is apparently of large molecular weight (>20,000) and constitutes 40–45% of the organic material in Black Trona Water from the DOE/LETC Black Water 1-A well. The fraction was investigated by means of 13C-NMR, FTIR, and fluorescence spectroscopy. Most of the carbon content is aliphatic (63%), with some aliphatic chains greater than 4 carbons in length. A substantial aromatic fraction exists consisting of condensed structures having 4–6 rings. The chemical nature of the polymeric acid fraction is compared to that of kerogen from the same formation. |
