DO NOT DISTILL NAPHTHA WITH DMT IN IT unless you are trying to distill the DMT too.

The boiling point of naphtha is much higher than the boiling point of DMT. All of the DMT will vaporize away with the naphtha.

You can distill DCM with DMT in it and you can distill acetone with DMT in it, because their boiling points are below that of DMT and the DMT will be left behind. But distlling naphtha will take the DMT with it, and maybe destroy it. It’s possible that the DMT will be unharmed and present in the receiving flask. But I have no idea. SWIM has never tried that.

If it works to distill the DMT and that's the intention, it sounds like a good way to purify it.
