Synthesize Boctane

[Enthalpy]

Hello you all!

 

Boctane is a rocket fuel, designed to be compatible with kerosene, performing 4s better than RP-1 and 7s better than Jp10.

According to http://www.freepaten...om/6415596.html it should be Cyclobutyl-Cyclobutane:

 

 

I wonder: how easy is it to produce?

Apparently naphthenic crude oil contain some cyclobutane, which I imagine is the difficult part of the job. How easy is it to bond to rings then? React with chlorine first, then Chloro-cyclobutane with cyclobutane? Impossible? Other ideas?

 

And would you know its physical properties: melting - flash - boiling points, density?

Reliable information for its heat of formation perhaps?

http://www.propulsio...ermo/thermo.inp gives +55,1kJ/mol, I estimate +35,4kJ/mol instead.

 

Thanks!

I could read Boctane's data published by Katorgyn, that is at the source.

 

Heat of formation is +80cal/g (I estimated +77cal/g)

Density 828kg/m3. Viscosity 2.4cPs @+20°C.

Melt -54.5°C / Flash +20°C / Boil +134°C / Autoig +205°C / Decomp +430°C

Solutions or mixtures of cyclobutane, cubane and boctane, or of two of them, may keep high performance and improve the liquid range. Especially when cubane becomes affordable.
