DCM, is paint stripper safe?

Migrated topic.

Where can someone find decent DCM? All my friend has found is Klean Strip "KS-3 Premium Stripper". MSDS reads
DCM: 60-100%
Methanol: 7-13%
Stoddard Solvent (mineral spirits, aliphatic petroleum distillates, white spirits): 1-5%

I know I can remove the methanol by mixing with water. Can I remove the stoddard solvent by distilation? DCM boils at 104f and SS at 300f +

Would it be safe to use after a water cleaning then distillation?
 
Just a distilation should do the trick. It would be pretty much ok to use as is, but all paint products with mainly DCM I've come across have this horrible rubbery stabilizer stuff in them, even though it;s never listed on the container.

I thought it felt thick. So theoreticaly would one distill until it stopped boiling at that temp meaning the DCM is all distilled out? Then discard what is left. You said a water cleaning to remove methanol isn't needed if distilled? Good to know. Thanks
 
just curious, why would swiy bother with mixture like this? seems a lot of work + toxic waste water stream. is dcm really worth it?

Just water washing a few times will do it. No distillation is really required here. DCM is heavier than water and it sinks. Aliphatics are lighter than water so they float. and methanol is miscible with water.

A separatory funnel will do this job a piece of cake.

It really is not a lot of work. And DCM is a seriously great solvent.

:: it evaporates really fast
:: it can pull freebases of almost anything people here may be interested in; dmt, 5-meo, bufotenine, harmine, harmaline, THH, psilocin, lsd, etc.
:: it can be distilled an reused many times (it boils at ~40C. )
:: it is not flammable, this is a great advantage when it comes to distilling.
:: it is great for pulling from minimally basic solutions. dmt can be pulled from a pH close to its pKa (8.68 ) with DCM, yet naphtha would not really pull anything at this pH.

DCM is the solvent of choice when it comes to extracting stuff from plants of uncertain or unknown alkaloid consistency or even alkaloids that are sensitive to extreme pH values like psilocin and bufotenine.

Not sure what you mean by "toxic waste water stream". All solvent is recovered, no one is going to find a stream to pour it in if that is what you mean...
But DCM is a very usefull solvent, especially with alks that degrade with high temps (DCM boils at about 140f)
 
i guess one could distill the methanol from the water wash u mentioned, but it wouldn't be anhydrous anymore. this is the waste water stream i was referring to. but if all components are fractioned, and recovered, then cool!

i wish i was set up with a proper solvent recovery and distillation set-up.
maybe some day:roll:

sounds like dcm has many advantages.
but alas, im a citrus hippie8)

perfect! A simple water wash it is! Thx!
 
Good to know that a simple wash can get rid of methanol.
However I read that pait stripper contains "wax binders" which is toxic...
Can it be removed from DCM with this water cleaning?

It may be dissolving in the DCM even after the wash.
 
Distillation work can be done without a fume hood?

Because BP of DCM is low and it's not flammable?

I am just worrying about safety.

Yes you can distill without a fume hood. You obviosly want good air ventalation and a proper setup.
