Just recently I had the time to siphon though the patent that I posted concerning the new denaturants that are being put on the war field, and have a few thoughts I would like to mention.
1. I am currently looking at all denaturants properties and devising a new extracting method.
2. The new denaturants come in three forms.
a.Separation inhibitors. Evidence is clear from waxes and fruity smells when solvent is evaporated. Not in all types. Seems that the mom and pops shops that sell the cheap p-fed but for high prices contain a wealth of separation inhibitors.
B.Reaction inhibitors. Will contain both
water and non-water soluble forms.
C.Combination inhibitors. The most dangerous kind because they cause bees to waste money, and potentially good meth. The hardest to remove. May contain amines with very similar properties (and may be part of other active ingredient). as P-fed. Also, amines seem to be the hardest to separate. Steam distillation will not work, many have similar vapor pressure.
3. Base on the information that I know, it tells me that no extraction method will be easy.
4. The new extracting method that I am currently working on is the basic separation tech. found in vogels 5th edition. Look this up, it is not has basic as It may sound, and this method allows you to separate most of the denaturants. This extracting method combined with using weak bases and weak acids during a/b extracting may give bees new hope, and even better is to use a column afterward to insure a pure product.
P.S. If one is not going to try a perfect isolation then I would not bother with the headache of wasting money on solvents, a simple a/b separating should be done and re-crystallized using ethanol, although I read that water can be used for ephedrine in "Purification of Lab. chemicals" latest Ed. One might try water sounds too easy though. One important thing though that should be noticed, this is especially for you Geez., you should not heat the shit out of it with solvents, take of advantage of freezing and not boiling when isolating is done. Some of the new additives are made to react with some reagents, and with the p-fed when trying to separate. Heat always favors the start of some reaction.
