Nitrocellulose
Molecular formula [C6H702(OH)3-r(ONO2)r]n
Main Physical and Chemical characteristic
Nitrocellulose is white floc and chip fiber, wish specific heat about 0.4 and relative density 1.65-1.67g/cm2, highly flammable, soluble in organic solvent such as ketone, ester, alcohol ether etc, sensitive to machinery impact when alcohol is lower. It can react with acid, alkali, oxidant and reductant.

2 Type and Specification
Based nitrogen content, nitrocellulose for dope falls into H and L. Type H is also called as alcohol as aster-soluble nitrocellulose, with nitrogen content 11.5-12.2%, while L grade nitrocellulose can also be named as alcohol-soluble nitrocellulose, with nitrogen content 10.7-11.4%.
