Description and Uses
1-Nitropropane (1-NP), a representative small nitro-alkane, is widely used as an industrial solvent and a fuel additive in automobiles and aircraft engines. The improvement effects of 1-NP on fuel combustion demonstrate that 1-NP served as an initiator can rapidly produce a large number of reactive radicals, which significantly increases the fuel conversion rate. In addition, among the small nitro-alkanes, the molecular structure of 1-NP endows it with a higher specific impulse. It provides the possibilities for its application as propellant in long-range rocket systems[1].
The solvent of 1-Nitropropane is mainly used coatings, inks and separation processes.
