摘要
Combustion catalysts for solid propellants are extracted with a solution comprising a solvent in which the catalyst is essentially insoluble and a solute which is an effective chelating agent for metal ions which are present as interfering impurities in the combustion catalysts. This treatment does not affect the activity of the catalyst as a combustion catalyst in a solid propellant; however, the removal of the metal ions greatly increases the pot life of the solid propellant composition prior to cure and enhances its stability after cure.
