storing Propionyl Chloride
i recently got a supplier to sell me 100ml sized bottles of Propionyl Chloride. Now i know how this tuff reacts with water and how it is in general.
My question is what is the BEST way to store this and how long can i store it safely before it degrades? And also should it be kept in a fridge or
room temperature or what? thank you

Amber glass bottle with teflon tape in the threads. If you're taking a cautious route, put it in a dessicater bag with 10-20g of magnesium sulfate or
your preferred dessicant.

I have noted that these compounds tend to escape--usually by means of eating the caps off (Bakelite caps with poly seals are no good, even when
refrigerated). The seals should be teflon.
I always kept mine (butyryl chloride) refrigerated. When properly sealed and refrigerated (it's dark in there), mine was good for months (and probably
still is).

Yup! The last time I had Oxalyl Chloride, it made itself into a gummy seething un-contained mess. Ate right through the cap. And, this happen
sooner, rather than later. Like right after delivery.
I was a younger man at the time, and perhaps I acted rashly. I simply took the bottle outside, laid it on its side, and quenched it with water. Poof!
Gone.
Teflon cap sounds like a good idea. Refrigerate.

I would store it at RT, but in a good glass bottle and inside a secondary container, to help keep it dry and protect it and the area around it, in
case it leaks. You can even put some baking soda in the secondary container if you want to reduce the acid fumes, my acid cabinet is pretty corroded,
as is much of the hood I work in due to lots of acids and fumes.

I store my acetyl chloride in a 100mL narrow mouth Qorpak bottle with a ptfe lid liner. I keep it in the garage. It seems to be doing OK. The only
thing my wife will let me keep in the fridge is H2O2.
I wanted to store my ether in the freezer but when I did it ruined all the food containing any fat, which included all the meat. Now I store it in
the garage with a smidgen of BHT.

I'm a big fan of Duran glassware and caps.
I use their PP caps for almost everything that is non corrosive.
The red (PBT?) teflon lined are perfect for anything corrosive that doesnt give out too much vapor (H2SO4).
The "Premium" caps (Teflon lined and PFA) are ok for anything corrosive but they are not as tough (mechanically speaking) as the red ones so anything
that creates pressure inside the bottle will eventually leak.
The "Pure" caps are PFA made with an inner liner AND a big toric seal. I just got five of them and havent tried them yet. I will definitely use them
for anything corrosive that gives out a lot of vapor (conc. HNO3)
And on a side note, pouring rings are crap: remove them !
