This also shows that the NO, groups in trinitroveratrol are situated 
in the positions 3, 4 and 5 
If this dinitrodiamidoanisol is treated with KOH we obtain the 
monomethylether of dinitrotrioxybenzene, a substance already obtained 
by Ninrzkr and KurrENBACHER from the said reaction-product of 
trinitrohydroquinonedimethylether and ammonia. 
In quite an analogous manner the same result was obtained for 
the oxyethyl compound :

This latter substance has been formerly obtained by NrietzkKr *) by 
treating trinitrohydroquinonediethylether with alcoholic ammonia. 
Although now the constitution of trinitroveratrol and of trinitro- 
pyrocatechindiethylether seemed to be satisfactorily determined, I 
have tried to furnish additional evidence by treating these substances 
with sodium ethoxide or methoxide ; then it was to be expected that 
the following changes might occur:

If now trinitrohydroquinonedimethylether (1) is treated with a 
solution of sodium methoxide in absolute methylaleohol the addition 
of each drop causes a brownish coloration which nearly instantly 
disappears. After a partial evaporation of the solvent, crystals are 
formed which melt at 92°; according to an analysis this is the 
trimethylether of dinitro-oxyhydroquinone.
