Hi, I would like to ask help and seek the expertise of professional chemists regarding nitrocellulose. 1) Can any grades of nitrocellulose (with varying nitrogen content/ degree of nitration) be used as a secondary explosive/detonator? If not, what is the threshold limit/concentration of the nitrocellulose grades considered as secondary explosives? 2) For nitrocellulose damped with solvent (water or alcohol), literatures specified that the damping agent/solvent phelgmatizes or deactivates the hazardous properties of nitrocellulose. In what does the solvent deactivates such hazardous properties? What is the underlying mechanism for this? 3) In what way does the degree of nitration affect the industrial applications, physical and chemical properties of nitrocellulose?
