When you need the nitro, simply let the solvent evaporate at room temperature (important, I have learned to point this out ;-) or pour the acetone solution into cold water (nitroglycerine precipitates). Storing, handling and transporting nitro this way is safe, as long as the solvent percentage does not drop too low. > -- Martin ArNO 2 You must Sign in before you can post messages.
