NITRO DERIVATIVES OF TOLUENE^335

permanent and transient solubility of a-trinitrotoluene in solutions of sodium sul-

phite of different concentrations. The trend of the curves is similar to that found

earlier by Barbiére [145].

FIG. 76. Influence of the temperature of sulphitation on the solubility of α− trinitro-

toluene at different concentrations of sodium sulphite (Smolenski and

Plucinski [146]).

FIG. 77. Influence of the time of sulphitation on the solubility of a-trinitro-

toluene at different temperatures and constant concentration (4%) of sodium sulphite

(Smolenski and Plucinski [146]).

The influence of the time of sulphitation on the solubility of β− and γ− trinitroto-
luene at different temperatures according to D. Smolenski and Plucinski [146]

is given on the Fig. 77.
