Abstract:

A Pilot Plant procedure was established for extracting BAAP FNH with methylene chloride using a three-stage, three-hour 35C extraction procedure with a 4.01.0 solvent-to-powder ratio scaled up to 1000-gallon still size. Residual modifiers left in the FNH were reduced to the 0.4 level. The critical impact of size of FNH particles to be extracted upon the overall requirement was illustrated. Blends of ball propellants meeting WC846 and WC870 specifications using the methylene chloride extracted FNH were prepared in order to test the effects of this extraction solvent on the finished powder. No traces of the methylene chloride extraction solvent could be found in powders as processed, and it may be safely assumed that the use of this solvent will not interfere with gun functioning or ballistic performance.
