- n. Gun cotton; -- so called because regarded as containing three nitro groups.
from The Century Dictionary and Cyclopedia
- n. A name often, though improperly, applied to guncotton under the assumption that the formula of cellulose or pure cotton fiber is C6H10O5 and that the action of nitric acid converts it into C6H7O5(NO2)3: but this latter formula should be written C6H7O2(NO3)3, since the product is not a nitro compound but a true nitrate, and the molecule of cellulose contains many times the number of atoms assumed in the above formula, which merely serves to indicate the relative proportions of the constituents.
tri- + nitrocellulose, because regarded as containing three nitro groups. (Wiktionary)
