3. Application：2,2′-Bis(ethylferrocenyl)propane (catocene) has been used as an efficient burning rate catalyst in composite solid propellants, which is possessed of the features of excellent overall and small removing properties. As a kind of bisferrocene derivative, 2,2′-bis(ethylferrocecnyl)propane can improve the combustion rate and reduce the pressure exponentwith the application of AP-based oxidizer in composite solid propellants.
