Again an ignorant's question, sorry for that...

Myrcene obtained industrially by pyrolysis of dirt-cheap turpentine can be hydrogenated efficiently, as claimed by
http://www.rsc.org/publishing/journals/GC/article.asp?doi=b916017p
into 2,6-dimethyloctane which is a good rocket fuel, or rocket propellant.

But I'd prefer to add ethane instead of hydrogen, at all of myrcene's three double bonds.
This would raise the boiling point, hence the flash point, improving safety, while the even more ramified alkane keeps a very low melting point.

Is this cheap to do in hundreds or thousands of tons?

Does it involve adding C₂H₅Cl at the double bonds, then react the chlorinated product with hydrogen? Or is there a more direct way, like for hydrogenation?

Which side of the double bonds do you expect the ethyls to choose? A random mix of all isomers would improve the melting point.

Or is all this unnecessary, because a cheap ramified alkane around C₁₆H₃₄ already exists?

Thank you!

Or could it possibly be that...

That ethane, propane, butane, saved from the flare stack, would make all the ramified alkanes I need, just using a bit of dirt-cheap chlorine maybe, and a moderate amount of heat?

And that as a consequence, starting from turpentine would just be a bizarre complication?

Man, I'm no chemist and have no plan to be one, so giving me such an answer is just fine!
Could you confirm?
