In order to get some fundamental informations related to a mechanism of carbonization, pyrolysis of the mono- substituted benzene derivatives (benzene, toluene, chlorobenzene, nitrobenzene, aniline, anisole, benzyl alcohol, acetophenone, benzaldehyde and phenol) was studied by use of a flowing gas reactor at below 600°C.
According to the initial temperature of decomposition, the thermal reactivities are arranged in the order as follow: ph-CHO>ph-OCH
3>ph-NO
2>ph-CH
2OH>ph-COCH
3 >benzene>ph-Cl>ph-NH
2>ph-CH
3>ph-OH. And the mechanism of the decomposition of the each derivative is suggested on the basis of the quantitative analysis of the products.
