Among the many factors determining the depth of conversion of a coal on hydrogenation, various structural features and, in particular, the nature and number of the labile oxygen-containing structures and bridge bonds, have an influence. There are statements that a direct relationship exists between the activity of a coal in destructive hydrogenation and the amount of oxygen in the ether/ester form, and also the nature of the bond of the mineral fraction of the coal with the organic constituents. The present paper is devoted to an investigation of the dependence of the tendancy of coal to undergo hydrogenation on the nature and number of the ether/ester and organomineral bonds in the structure of the coal. In experiments the researchers used the hydrolytic destruction of the coals and subsequent selective hydrogeneatin with sodium tetrahydroborate. 17 refs.
