Nitrocellulose cotton is made from the technics which refined cotton and nitric acid.
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.
