Abstract

The change in composition and characteristics of anthracene oil from coal tar on reacting with hydrogen acceptors (α-methylstyrene and nitrobenzene) at 360°C is studied. Besides the formation of cumene and aniline by the transfer of hydrogen from the anthracene oil, α-methylstyrene and nitrobenzene react with components in the anthracene oil to form products that cannot be determined by chromatography. In addition, polymerization of the components in the anthracene oil is observed. The anthracene oil is analyzed after reaction with α-methylstyrene and nitrobenzene by means of gas–liquid chromatography, elemental analysis, thermogravimetric analysis, gel permeation chromatography, NMR 1H spectroscopy, IR spectroscopy, and UV fluorescent spectroscopy.
