Infobox references

1-Nitropropane (1-NP) is a solvent. It is a colorless liquid, an isomer of 2-nitropropane (2-NP), and classified as a nitro compound.

Preparation

1-NP is produced industrially by the reaction of propane and nitric acid. This reaction forms four nitroalkanes: nitromethane, nitroethane, 1-Nitropropane, and 2-Nitropropane. 1-NP is also a byproduct of the process for making 2-NP, which is done by vapour phase nitration of propane.

Uses

Most 1-nitropropane is used as a starting material for other compounds. The other uses are solvent-based paints, solvent-based inks and adhesives, and as a solvent for chemical reactions.[5]

Safety

1-NP is toxic to humans and can cause damage to the kidneys and liver. The vapours are irritating for the lungs and eyes and the maximum exposure rate is 25 ppm.[6] It is not known to be a carcinogen.

Reactions

1-NP decomposes under the influence of heat into toxic gases. It also reacts violently with oxidizing agents and strong bases.[7]
