Abstract
Dynamics of the accumulation of oxygenated groups during coal ozonation in chloroform is investigated. It is shown that the oxygen content of the organic matter of coal is determined by the availability of reaction centres for ozone molecules. High-molecular water-insoluble acids prevail among coal ozonation products.
