I learned of Butacene in the paper "The Effects of Ferrocenic and Carborane Derivative Burn Rate Catalysts in AP Composite Propellants: Mechanism of Ferrocene Catalysed Combustion" by T.T. Nguyen. The paper is currently viewable on the web as a pdf. The paper gives the chemical structure of Butacene. I don't readily see from the structure how to make Butacene from HTPB (I'm a chemical engineer, not a chemist). I appreciate the information on the hazard of ferrocenium perchlorate. I've been on a quest to make 29mm nozzleless core burners, but I need a fast-burning AP composition. I am finding that high burn rates are difficult to achieve, without resorting to exotic materials or increasing hazard. I found this webpage as a result of searching Butacene via Google.

A heads up - ferrocene reacts with AP to produce ferrocenium perchlorate, which is highly sensitive to shock/friction/static. Butacene doesn't exhibit this issue to the same extent, since the metallocene molecules are bound to the HTPB, but adding neat ferrocene crystals may cause the propellant to become extremely sensitive, especially as it ages. Use wisely and have fun! Can't wait for MWP... Hey Scott, thanks for dropping by!

That is some pretty cool stuff with the embedded wires and all. I'd love to try that myself! Oh yea, I read the section on the Arcas and Super Arcas that you mentioned above.

I'll be mixing at Gene's house in MO now, so I'm sure I'll be having some fun in the years to come. ;) I'm enjoying your TDK site. David,
