✦ Synopsis

The results 0 . a kinetic study of the diazotization of m-chloroaniline (l), are combined with equilibrium and thermodynamic studies of m-chloroaniline and its hydrochloride(2), in order to evaluate AF*, AH* and AS* for the nitrosation of m-chloroaniline, which is the rate-determining reaction in the diazotization of this amine.

While the values of k,, for rn-chloroaniline and for aniline, differ considerably, those of k3 were found to be of the same order.

The reaction mechanism suggested by H. Schmid ( I 3 ) for the diazoti-(13) H. SCHMID, Mh. Chem., 85, 428 (1954). (14) This technique was already used by H. SCHMID and co-workers, e.g.
