Perchlorate salts: (explosive) reactivity with methane?

I read everywhere about the explosive reactivity of perchlorate salts (e.g., $\ce{Na}$, $\ce{Ca}$, $\ce{NH4}$ [especially]) when mixed with organic materials or solvents, yet I find no information about its reactivity with methane.


Can anyone comment please?




In general, explosion of *alkali metal* perchlorates (at least in small quatities) is deflagration, with the perchlorate providing oxygen for combustion of another component of a mixture, rather than detonation (due to decomposition of the perchlorate). However, perchloric acid itself and other inorganic and organic perchlorates such as [cis-bis-(5-nitrotetrazolato)tetraminecobalt(III) perchlorate](http://en.wikipedia.org/wiki/Pyrotechnic_initiator) can transition from deflagration to brissant **detonation**.


So, to answer your specific question, *gaseous* methane would burn more readily in the presence of Group I perchlorates, but the flame-front would be limited by the small contact area and low concentration of methane at the solid/gaseous interface. On the other hand, if one were to synthesize [methyl perchlorate](https://sites.google.com/site/energeticchemical/alkyl-perchlorate-esters) or [ethyl perchlorate](http://pipeline.corante.com/archives/2006/05/30/things_i_wont_work_with_frisky_perchlorates.php), one might not be able to perform subsequent syntheses.


So, to avoid maiming or perhaps a terminal experiment, eschew perchlorates.
