2,4,6-Trinitro-m-xylene forms addition products less easily than α− trinitrotoluene.

Undoubtedly the two methyl groups present in the ring reduce its ability to form

addition compounds.

(Solid solution, system V of Roozeboom)

According to Jefremov and Tikhomirova [10], 2,4,6-trinitro-m-xylene contrary

to both sym-trinitrobenzene and 2,4,6-trinitrotoluene does not combine with

such hydrocarbons as acenaphthene, anthracene, phenanthrene, fluorene or naph-

thalene.

The constitution of 2,4,6-trinitro-m-xylene was determined by Grevingk [13].

He nitrated both 2,4- and 4,6-dinitro-m-xylene and obtained the same product.
