How to store methyl iodide
The forum has a bunch on things about making methyl iodide, but practically nothing about storing it. I'm working in a garage that has about as much
climate control as a hole in a tree, and I don't have a working fridge or anything for my lab. Would just wrapping the bottle in Al foil to keep the
light out, storing it under copper, and wrapping the glass threads of the bottle in teflon tape be enough? I don't think I'm going to use the MeI for
some time, so this is going to be >1 month storage. How should I try storing this?

Don't make it until you're ready to use it. Or wait until winter.
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

Right now, it's still pretty cold here, with highs in the 50s or 60s (F, not C ).

I stored my homemade stuff in my freezer in an amber glass bottle containing a piece of clean copper wire. The bottle had a standard rubber seal and
seemed to contain it just fine. In the lab I worked in, it was stored in the fridge in its original bottle from Sigma and I never noticed any
evaporation of it in there either.
So if you have a bottle with a really good seal, fridge is probably fine. I wouldn't want to store it any warmer though, cause even if the bottle can
contain it, it would become pressurized, and you'd just be asking for a sudden burst of toxic vapors whenever you open it.

Ok, in that case, I'll use the MeI within a few days (< 1 week) for the first step in an ionic liquid synth (shown below), or destroy it. I'm
making the MeI to test a new method of production, more details here: http://www.sciencemadness.org/talk/viewthread.php?tid=156953

If you can dig a hole you can make an underground storage. In the place where I live the temperature 2 meters below the ground is up to 14 deg C. Air
temp in summer is even up to 40 deg C.
I have some bromoethane in GL45 bottle with red PBT-lined cap. During summer it was in a place where the temperature was nearly reaching it's boiling
point. No leaks. When I opened it once I've noticed some hissing but I I didn't lost almost anything which I checked by weight of the flask.

First the neighbors heard a blower fan coming from the garage, then they see me burying something in the backyard Not at all suspicious.
