Lining an old oil drum with something...

[Methiah]

I'm assuming that an old oil drum will not work for the extraction technique mentioned in

Post 57517 (missing)

(Mister_Clean: "Re: New extraction technique?", Stimulants) since the use of lye will no doubt cause an unwanted reaction with the steel of the oil drum. Can someone think of something I can line an old oil drum with before I use it for such a project? I'm thinking something plastic-like, but also something that can withstand heat. Any ideas? Thanks.

....with a signature like that, how could I refuse?

These excellent chemical resistance tables tell me that Hydrochloric acid, Sodium Hydroxide and Toluene can be safely utilised in a very easy to find Polyproylene or Polyethylene drum, that will comfortably handle the 80 Celcius temperature required.

No need to bother lining a metal drum.

On many of these drums you can place a tap fitting at the base to make a super Sep funnel.

_{P.S. I would give the bug sprayer idea a miss, though}
