Aniline
Aniline was used as a hypergolic fuel in several early rocket engines of the 1940's. It was used straight or with furfural alcohol to improve its cooling properties. It was quickly succeeded after the war by hydrazine in storable rocket applications. Aniline ignites spontaneously in the presence of red fuming nitric acid, and with sodium.

Aniline is a colorless, oily liquid which darkens on exposure to light or air. Its odor is weakly amine. Solubility is 3.5 g in 100 g water @ 20C. It is stable under ordinary conditions of use.
