NITRO DERIVATIVES OF BENZENE^245

FIG. 48. Change in molecular composition of acids during nitration. AB - the
curve of limiting compositions (Hetherington and Masson [33]).

FIG. 49. Molecular compositions of acid present in the organic layer (A), acid layer

(B), and in the aggregate (C). The tie-lines show the conjugate layers (Hetherington

and Masson [33]).
