A hydrogen-1, carbon-13, and nitrogen-15 nuclear magnetic resonance study of p-benzoquinone polymers incorporating amino nitrogen compounds (synthetic humic acids)



A hydrogen-1, carbon-13, and nitrogen-15 nuclear magnetic resonance study of p-benzoquinone polymers incorporating amino nitrogen compounds (synthetic humic acids)



Soil Science 134(5): 277-293



A chemical and NMR study of a set of phenolic polymers of the type long proposed as possible synthetic models for humic acid was conducted. Twelve polymers were prepared by air oxidation of p-benzoquinone, and p-benzoquinone plus ammonium chloride, glycine, diglycine, triglycine, alanine, dialanine, alanylglycine, glycylalanine, casein, casein hydrolyzate, and 95 percent 15N-enriched ammonium chloride.
