from The Century Dictionary and Cyclopedia
- n. A product obtained by treating cotton fiber for a short time with dilute sulphuric or hydrochloric acid, washing out the residual acid, drying, and subjecting the resultant hydrocellulose, which is readily reduced to fine powder, to the action of a mixture of concentrated nitric and sulphuric acids, as in the common process for making guncotton. Nitrohydrocellulose resembles ordinary gun-cotton, but is more sensitive to shock. It has been used in the manufacture of detonating primers.
Sorry, no etymologies found.
The latter also, when distilled with hydrochloric acid, yields a larger proportion of furfuraldehyde than is obtained from nitrocellulose and nitrohydrocellulose.
On exposure to air, nitrohydrocellulose becomes yellow and decomposes; nitro-oxycellulose is rather more stable, whilst nitrocellulose is unaffected.
