Coal Dehydrogenation Using Quinones or Sulfur

摘要

Seven coals have been dehydrogenated with sulfur in refluxing o-dichlorobenzene with the rate or reaction being followed by analysis of the H_2S swept from the reaction by an N_2 stream. Dehydrogenation using benzoquinone was not successful due to benzoquinone incorporation into The coal. The chief structure change on dehydrogenation with sulfur is loss of aliphatic hydrogen With a concomitant increase in coal aromaticity.
