Development of Instrumental Techniques for Coal Surface Analysis: Functional Group Analysis in Coal by (Sup 31)P NMR Spectroscopy: Quarterly Report, October 1, 1987-December 31, 1987.

摘要

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. To achieve our objective, we will be exploring the use of Fourier transform (sup 31)P nuclear magnetic resonance spectroscopy, which has in recent years become a routine method for the measurement of both liquid and solid materials. In order to apply this technique most efficiently to the qualitative and quantitative analysis of functional groups in coal materials, it was necessary to survey the literature for suitable reagents and for previous analytical efforts involving the NMR spectroscopy of derivatized functional groups. What follows is a summary of our search. 19 refs., 2 tabs. (ERA citation 14:007233)
