Abstract

The reaction of chromic oxide ion in aqueous solution with twelve kinds of coal samples has been studied. It was found that the chromic oxide ion reacted selectively to catechol type compounds at 273K by the experimental result for some kinds of coal model chemical compounds. The existence ratio of catechol type components in each coals was estimated at 273K.
