I don't understand exactly what you say.
First, after extraction of the base and drying the solvent, you xtallize. There are many methods
1) PIHKAL evaporate solvent, dilute base in IPA, neutralize with conc. HCl and add 4 volumes from IPA of ether or acetone.
2) Same, but prepare IPA+ aq HCl and dry it MgSO4 or NaSO4. Neutralize the base directly with your acid IPA, then add ether or acetone.
3) Gass your dried solvent + amine (toluene or ether) with HCl, wash with acetone.
4) Dilute the base in 6 vol or so of acetone, neutralize with aq. HCl and put in the freezer, recover crystals, evaporate everything and do it again.
5) Add to your toluene extracts IPA and aq HCl to get a homogeneous mixture at pH 5, evaporate in vacuo (or at normal pressure) removing water, IPA and toluene, when you have a lot of crystals in the flask and some toluene, take them out, take the rest out with acetone, filter and wahs witha cetone.
6) and more and more...
Once you have your crystals, you can rxistallize to get more pure stuff (or specially if your crystals or not white) by diluting them in the minimum amount of boiling IPA, then add 4 volumes of cold acetone. For MDA use methanol.
If you make things correctly and get nothing, think about a failure in your production.
