Liquid-phase ozonation of vitrinites of coals of various metamorphic stages: Product composition

The fractionated products of ozonation of vitrinites of Kuznetsk coals of different metamorphic stages in chloroform have been characterized by IR spectroscopy, thermogravimetry, and gas chromatography-mass spectrometry. High-molecular-mass compounds insoluble in water prevail in the products. Water...

Zusammenfassung:The fractionated products of ozonation of vitrinites of Kuznetsk coals of different metamorphic stages in chloroform have been characterized by IR spectroscopy, thermogravimetry, and gas chromatography-mass spectrometry. High-molecular-mass compounds insoluble in water prevail in the products. Water-soluble products are ketones, oxyalkanols, lower aliphatic acids, and hydroxy- and dicarboxylic aromatic acids.
