Functional group analysis in coal by sup 31 P nmr spectroscopy
The primary aim of our research is to develop a convenient, sensitive, reliable and rapid technique for the qualitative and quantitative analysis of -COOH, -OH, -NH and -SH functionalities in coal, on coal surfaces, and in coal-derived materials such as condensates and extracts. Two reagents from a list of eleven were selected for the quantitative and qualitative {sup 31}P nmr analysis of a substantial number of phenols in an Illinois No. 6 low-temperature pyrolysis condensate. In the course of our reagent evaluation, a promising lead for an improved reagent containing selenium was discovered. Preliminary results on the application of our {sup 31}P nmr tagging technique to a solid carboxylic acid are discussed. 2 refs., 1 fig., 2 tabs.
