Chemical selectivities disguised by mass diffusion. IV. Mixing-disguised nitrations of aromatic compounds with nitronium salts. 4th communication on the selectivity of chemical processes

The disguise of the intrinsic selectivity of competitive, consecutive reaction systems by the mixing process is demonstrated experimentally using the fast nitration of a number of aromatic compounds with nitronium salts in nitromethane. The measured product distributions were compared with the distributions predicted from our mixing-reaction model developed previously [2] [4]. This comparison enabled the relative intrinsic rate constants for the second nitration step of the aromatic compounds investigated to be determined.
