You don't need DCM, just use isoprapanol, or methanol as blogfast used i think.

DCM is a simple distillation from paint stripper. You can even do it straight from the can.

With a BP of barely 40 C you need to use iced water for any refluxers/condensers.

Sheesh, that really is low. I use ice water usually, but I don't salt it (I don't know how much of a difference it would make) because my pump claims
that it only works in fresh water (ie, not salt water like in marine aquariums).

what about adding
antifreeze or maybe some IPA to lower the temperature.
Dont ask me, I only know enough to be dangerous

Our college lab uses a chiller filled with antifreeze that's looped out to the condensor. It seems to work quite well. IPA would be a less toxic
solution, though.

New Soxhlet arrived today (donated the last one to a local Uni)
The DCM does not pass through any volume of these cut up vinyl golves, so the Soxhlet did not work at all.
Probably better to boil & reflux.
Trying it with merely Cold water was Interesting - the DCM at the top was refluxing from the heat of the incoming DCM stream
Reached the 3rd bulb of the Allhin condenser.
With Ice added, it did the same, just in the first, and half of the second bulb..
Edit:
Abandoned the attempt for now.
Cleanup was a bitch - the DCM makes these gloves into a mush that sticks to the glass like crazy.

I'm finding that polymer goos are a pain to clean up as well. I've dusted off my plans to extract something useful from that paint stripper. It left
a mess in the test tubes. I can't imagine trying to scrub it out of a boiling flask. Hot methanol managed to dissolve a lot of it.

And most, not all, of his videos are redone versons of both yours and myst, nothing against him he makes good videos, but I think he should be more
