Back in the 70's a colleague of mine,Ray Goodson, introduced me to
hydroxylamine perchlorate(HAP) and its synthesis as a possible liquid
oxidizer.
It's one of the most hygroscopic solids with 95 grams dissolving into 5g of
water and It's dense too and easy to make through several methods.
United Technologies/CSD, where Ray and I worked, had a contract with the
Navy to investigate torpedo propellants including HAP. There was several 5
gallon cans of 85% HAP stored at the Sunnyvale facility which Ray watched
in case it would become available on the surplus market which we lost track
of when we were transferred to the Coyote facility in South San Jose.
So I made some HAP and found it interesting but expensive to obtain the
precursors and LOx was far more attractive for my needs as an amature at
the time. If anyone wants to check HAP out I can offer some precure
ingredients that I still have to get you started.

I found 4 such MT cylinders in a parking lot near me, I collected them
to see if there were any usable components like valves or vessels.
The threaded 16g CO2 ones might be more useful - they are used in guns.
I thought of using them for TEA/TEB cartridges.
Talking of unusual chemistry and torpedoes, the Spearfish, YU-10 and
others use Otto II fuel (75% propylene glycol dinitrate with 23% sebacyl
chloride desensitiser and a 2% 2-nitrodiphenylamine stabiliser) plus
hydroxalymine perchlorate/water.
Sounds like a pair of touchy explosives, but the Navy uses them in
torpedoes and they seem happy about their safety - and they are stored
in torpedoes for long periods.
I don't know the Isp you might get, but afaict it could be used as a
space storable rocket propellent. Nasty, but vapour pressures are low.

Nothing too impressive but too bad they're not refillable. DOT regsdrug,
probably make it too expensive to certify for reuse.

You can buy thionyl chloride batteries, in the UK at least, but they
are
the wrong type size and construction for rocketry use.
And nitrous is just about to be banned in the UK, in theory as a
but mostly because users litter the empty cylinders.46
