First of all just dont work with plastic next time. That being said, if I wanted to clean some suspected plastic off my product, I`d dissolve the freebase in acetone, add FASA, collect the precipitates after a couple of days, wash them with cold dry acetone, and then reconvert back to freebase using the slow water crystallization method described in BLAB tek.
The plastic or plasticizers would very probably stay dissolved in the acetone when the fumarates precipitate after adding FASA. The acetone wash will not dissolve fumarates and will help making sure the traces of plastic are removed. The water freebase crystallization step would be an extra step making sure you`re cleaning it off any more polar plasticizers that might have come across...
Agreed, this would probably be the most guaranteed method to remove plastic.
A mini-A/B would probably be
almost as effective, but still slightly less so. Adding a re-x or two at the end would probably be plenty thorough. The benefit of this method would be that a person performing an extraction already has all of the required materials on hand.
