Some issues of hydroxyl derivatives of ferrocene as burning rate modifiers of composite propellants

Abstract. For many decades, a significant number of scientific papers and patents have been published every year, indicating that a new derivative of ferrocene is emerging, which can be successfully used as a burning rate modifier for a solid composite rocket propellant (CP). Usually, authors of such works present only research results confirming their thesis about the usefulness of a given derivative. It cannot be ruled out that the authors of these works actually obtained a useful derivative, but - if comprehensive research results are lacking - this cannot be said with certainty. In this work, in the form of a discussion of case studies, the main aspects that - according to the authors - are worth paying attention to when analyzing literature reports on new ferrocene derivatives, useful as modifiers of the burning rate of CPs, has been characterized. Special attention was paid to ferrocene derivatives containing hydroxyl group, because on the one hand they have been known for a long time, and on the other hand they have been studied relatively rarely.
