摘要：

Thermal reactions proceeding through hydrogen transfer from the polyaromatic compounds of coal tar pitch to model organic compounds (nitrobenzene, chlorophenols, and chloraniline) are investigated. Within the temperature range 270-360 degrees C, there is a complete conversion of nitrobenzene into aniline (with a yield of 75-82 %) and condensation products remaining in the pitch. It was found that 4-chlorophenol enters hydrodechlorination starting at a temperature of 300 degrees C and leading to the formation of phenol and condensation products. The reactivity of di- and tri-chlorophenols is higher than that of 4-chlorophenol. The features of the reactions are compared using coal tar pitch and hydroaromatic compounds as hydrogen donors.
