1: Because it would be a waste of solvent that can be re-used over and over
2: It would take a LONG LONG time, d-limonene evaporates slower than water.
3: d-limonene does not just dissolve mescaline from the cactus, it dissolves plant fats and other junk.
The vinegar is a purification because it separates only the alkaloids. (though still not only mescaline)
(Though SWIM's preferred cactus tek is the resin tek, by the way)
Good luck
