Some d-limonene got mixed with the vinegar evaporation so now I have some orange d-limonene mixed with the mescaline. Is there a way to purify this and take away some of the d-limonene?

And would it be bad to do the MEK wash with the d-limonene that got left behind?

No one? :\

The limonene won't dissolve anything you want in your extract. An MEK wash should remove the unwanted content, to include the limonene.

So basically, I shouldn't worry about it?
