- n. Nitroglycerin.
from The Century Dictionary and Cyclopedia
- n. An element in some compounds, meaning ‘niter,’ and usually implying ‘nitrogen’ or ‘nitric acid’; specifically, as a prefix in chemical words, indicating the presence of the radical nitryl (NO2) in certain compounds: as, nitro-aniline, nitr anisic acid, nitro -benzamide, nitro-benzoic acid.
- n. An abbreviation of nitro-powder.
- n. It is also employed, very commonly but in regard to technical use incorrectly, as a part of the name of a compound which does not contain the radical nitryl (NO2) with its nitrogen directly united to carbon. Thus nitroglycerin and nitrocellulose (guncotton) are not nitro-compounds in the technical sense of the term, but nitrates.
