nitrocellulose

Nitrocellulose cotton is made from the technics which refined cotton and nitric acid ,vitriol that through esterification and stable process etc. Molecular formula:- [C6H7O2OH3-r (ONO2)r]n-Nitrocellose cotton is white floc and chips fibre, the density is 1.65-1.67g/cm3 , can be liquefied in acetonet, ethyl acetate, camphor&anol liquid etc. It is flammable., and sensitiive to machinery impact when the moistening agents is lower. Because the different condition during nitration, nitrocellose have a different nitrogen content and solubility. When the nitrogen content exceeds 12.5%, it is explosive, and unstable.
