| Abstract: | A comprehensive research has been conducted on the N 2 O 4 O 3 nitration aromatics reaction It is found that the isomer distribution of N 2 O 4 O 3 nitration substituted aromatic differs from that of mixed acid nitration substituted aromatic. The reasons for the difference have been analyzed. It comes that P orbital in substituent group can assist N 2 O 4 O 3 nitration aromatics in substituting ortho, which has been proved by the experimental results and the calculation results of the electron density distribution. |
