Toluene pull than naptha clean up

[DavidFox]

Is it possible to just pull with xylene/toluene, evap, then pull the evaped goo/crystals with naptha at 40-60C, then re-crystalize in a freezer -20C to get a cleaner product? and use less naphtha less oily more pure? Can i actuly use nitrobenzol? i dont have much naptha and its not avalible but i like the idea of clean product. Thank you for your help

If you have to ask this question, please don't use nitrobenzene (nitrobenzol).

Rather than evaporating the toluene/xylene, wash the DMT out with a little acid (e.g., vinegar). Add base to the vinegar and pull from this 'new' base soup with the naphtha. This is known as a 'mini A/B'.
