Less Common and Obsolete Combinations
- Hydrazine + nitric acid (toxic but stable), also known as "Devil's venom", as used in the Soviet R-16 rocket of the Nedelin catastrophe.
- Aniline + nitric acid (unstable, explosive), used in the WAC Corporal
- Aniline + hydrogen peroxide (dust-sensitive, explosive)
- Furfuryl alcohol + IRFNA (or white fuming nitric acid)
- UDMH + IRFNA - MGM-52 Lance missile system
- T-Stoff + C-Stoff - Messerschmitt Me 163 World War II German rocket fighter aircraft, for its Walter 109-509A engine
- Kerosene + hot hydrogen peroxide - Gamma, with the peroxide first decomposed by a catalyst. Because of the heat from H2O2 decomposition, this is arguably not a true hypergolic combination. Cold (undecomposed) hydrogen peroxide and kerosene are not hypergolic.
The corrosiveness of nitrogen tetroxide can be reduced by adding several percent nitric oxide (NO), forming MON.

Famous quotes containing the words common, obsolete and/or combinations:
“This, our respectable daily life, on which the man of common sense, the Englishman of the world, stands so squarely, and on which our institutions are founded, is in fact the veriest illusion, and will vanish like the baseless fabric of a vision; but that faint glimmer of reality which sometimes illuminates the darkness of daylight for all men, reveals something more solid and enduring than adamant, which is in fact the cornerstone of the world.”
—Henry David Thoreau (1817–1862)
“Had it not been for you, I should have remained what I was when we first met, a prejudiced, narrow-minded being, with contracted sympathies and false knowledge, wasting my life on obsolete trifles, and utterly insensible to the privilege of living in this wondrous age of change and progress.”
—Benjamin Disraeli (1804–1881)
“You should try to understand every thing you see and hear; to act and judge for yourselves; to remember you each have a soul of your own to account for; M a mind of your own to improve. When you once get these ideas fixed, and learn to act upon them, no man or set of men, no laws, customs, or combinations of them can seriously oppress you.”
—Jane Grey Swisshelm (1815–1884)
