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

(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.

Thanks.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
