Реферат:
The correlation between the energy threshold of laser ignition of coals and the degree of their aromaticity was investigated. The 13C CPMAS NMR spectra of different marks of coal were recorded. Quantitative data on the distribution of carbon over structural fragments were obtained from these spectra with the help of modeling. It is shown that an increase in the rank is accompanied by an increase in the intensity of the signals of aromatic carbon and a decrease in the intensity of aliphatic carbon signals. In addition, with an increase in the rank, the content of CH2, C-O-C, COOH functional groups in coal decreases. The direction of the correlation between the energy threshold of ignition of hard coals and the degree of their aromaticity was determined, and the strength of the correlation was established.
