Hi.
If you using not complete pure E (when talking about pure E, I mean reX. E from a properly extraction) in E/I2/rP reactions, what happens?
SWIM have made a pillextraction, boiled the pills mass 3x in NP, once i acetone and extracted with IPA. When doing the foil test, the powder leave a little bit crap. The same powder after a a/b extraction leave nothing.
SWIM have done some small reaction, 2-7grams, with a mix of powder which have not been cleaned with a/b at the end and a/b extracted powder, every time with about 50% yield and got a fine product.
SWIM is not blessed with the best a/b-extractions skills, everytime he lose a lot of the product and wasted a lot of chems. Therefore he would rather use the powder from the first extraction, compared to do a a/b on the product from the first extraction.
But will that 'cause crappy meth at the end?

Hi,
If the product from the alcohol extraction is dirtier than the a/b product, you could try doing an a/b from the start. If you can get tetrachloroethylene, the Tetra Trap is probably one of the easiest and most effective a/b extractions. Geez's Waterless A/B would probably also work fine for you.

yes it will give you crappy product back, do it right or dont do it at all

do it right or dont do it at all
SWIM have the same opinion, whats why is ask the question![
>:(
Can anybody tell what the present of gakk Actually do in a reaction?
-
What the gakk will do in a reaction depends on which gakk it is, and there are many.
-
..that may depend on the impurities...
SWIM once steam extracted 8% ma Huang, acidified the distillate, removed the water under water and cleaned the resulting Ephedrine.HCl with a little cold acetone.
The ephedrine was quite away from pure - it had a violet colour, but was crystalline. Swim used this directly in a so called "LWR-reaction", and cleaned the product by steam distillation, followed from recrystallisation (IPA/MeOH) to get a very pure product.
So the use of unpure Ephedrine is possible... (but purification is still better ;))
