Abstract
Novel compounds are provided having the formula ##SPC1## Wherein R is hydrogen or lower n-alkyl and the ether oxygen atoms are attached in the 1,3 or 1,4 positions to the R substituted benzene rings, R being in the 2 or 5 positions when the ether oxygen atoms are in the 1,3 positions and R is lower n-alkyl. These compounds are useful as explosives characterized by good thermal stability.
Claims11
A nitro compound of the formula ##SPC6##
- wherein R is hydrogen or lower n-alkyl and the ether oxygen atoms are attached in the 1,3 or 1,4 positions to the R substituted benzene rings, R being in the 2 or 5 positions when the ether oxygen atoms are in the 1,3 positions and R is lower n-alkyl.
The process of preparing a nitro compound of the formula ##SPC7##
- wherein R is hydrogen or lower n-alkyl and the ether oxygen atoms are attached in the 1,3 or 1,4 positions to the R substituted benzene rings, R being in the 2 or 5 positions when the ether oxygen atoms are in the 1,3 positions and R is lower n-alkyl, which comprises reacting a compound of the formula ##SPC8##
- werein R is hydrogen, lower n-alkyl or nitro and the ether oxygen atoms are attached in the 1,3 or 1,4 positions to the R substituted benzene rings, R being in the 2 or 5 positions when the ether oxygen atoms are in the 1,3 positions and R is lower n-alkyl or nitro, with conc. nitric acid.
