3 -nitrotoluene was found "not to have oxidising properties" after the following results


were obtained:

2550 ms



Reference: 65 % Nitric acid + cellulose (1 : 1 ratio)


 



In all cases, the burning time of the m-Nitrotoluene / cellulose mixtures was found to be considerably longer than the reference mixture. Since no spontaneous ignition was observed either, m-Nitrotoluene was found to have no oxidising properties.


Interpretation of results:
GHS criteria not met
Remarks:
no oxidising properties
Conclusions:
A test conducted according to the Guideline EC A.21 showed that the mean pressure rise time for 3-nitrotoluene (6850 ms; five run tests) was longer than the pressure rise time for the reference substance (65% nitric acid, 2550 ms; single value). Furthermore, no spontaneous ignition was observed. Therefore, 3-nitrotoluene was found to have no oxidising properties (Currenta 2009).
Executive summary:
