Thermochemical and explosive properties of chloronitrobenzenes

Desvergnes has tested the explosive properties of l-chloro-2,4-dinitrobenzene in a manometric bomb. At a density of 0.25, on comparison with other dinitro compounds, he obtained pressures  

It can be seen from the above that the explosive properties of chlorodinitrobenzene are slightly inferior to those of dinitrobenzene. 

Experiments with chlorodinitrobenzene in mixture with picric acid for filling shells have given no satisfactory results. 

In the explosives industry only the nitro derivatives of p-dichlorobenzene and 1,3,5-trichlorobenzene have gained any importance. 

Mono- and di-nitro derivatives were first obtained by Jungfleisch [9] in 1868. Kijmer [36] demonstrated that the product of dinitration of p- dichlorobenzene consists of the a- and 0- isomers. Morgan and Norman [37] isolated yet another one, the y- isomer. The preparation and properties of all these isomers were investigated by Holleman [38],
