This is your x20 extract I take it?
I'm not sure if your extract is in alcohol or in powder presently or if it's the base or the salt, as your not very clear. You'd do well to tidy up your notes.
Let's get you to the salt in water from wherever you may be first. You'll need the following...
- pH meter/papers
<hardware store>
- HCl
- Lye
- rock salt
- drying agent MnSO4, CaCl2, etc.
- organic solvents (xylene/toluene, naphtha, etc)
- isopropyl alcohol
- water
- fluid vessels and transfer mediums (beakers, sep funnel, or ghetto equivalent)
- PPE (gloves, glasses, apron, etc) PUT IT ALL ON FIRST GREEN HORN!
1. Add whatever you have, alcohol or powder, to a volume of water.
2. Measure the pH.
3. Adjust to pH 7 with 10% HCl in water with good stirring. Don't over shoot it; add HCl drop wise, then stir, then wait and measure again.
4. Let the solution rest and confirm pH 7
5. Evaporate of the alcohol (if you know you have the salt in alcohol you'd start here)(n/a if you have the powdered extract)
6. Wash aqueous solution x2 with at least 20% aqueous volume equivalent of organic solvent like toluene or xylene. Repeat until wash fluid is clean.
7. Wash aqueous solution with at least 20% aqueous volume equivalent of organic solvent like naphtha. Repeat until wash fluid is clean.
8. Add a cooled solution of 50% lye (CAUTION MIXING THE LYE WITH WATER RELEASES HEAT) in water until pH13. (again don't over shoot it). Smell it! Kinda fishy, no?
9. Add rock salt until no more will dissolve in the water.
10. Extract freebase x3 with organic solvent (toluene/xylene) of at least 20% aqueous volume equivalent.
11. Dry it by letting it sit for a few hours, then decanting into another vessel with drying agent (anhydrous MnSO4 or CaCl2)
12. Filter out the solids.
13. Gas or titrate with 10% HCl, then dry the salts and wash salts with organic solvent.
14. Recrystalise by dissolving salts in minimum amount of boiling isopropyl alcohol (CAUTION FLAMMABLE) and allowing to cool to room temp, then cover an place in the freezer.
15. Decant of the alcohol and marvel at the beautiful sight before you.
That's enough spoon feeding for you green horn. You need to find out how to do titration, gassing, filtering, etc. If you can't or its just too hard then find another hobby and pass me that extract LOL :p
