SWIM did a extraction on some ephedrine pills.
Crushed the pills.
Boiled 3 times in Xylene/Ethylbenzene.
Boiled once in acetone.
Extracted 2 times with hot dry IPA.
If the yield was 100%, SWIM would get about 45g. E.
By huge mistake, SWIM forgot to dry the Xylene/Ethylbenzene which was used for the first boil. The Xylene/Ethylbenzene for the last two boils and the acetone was dried. And of'cause SWIM did first discovered the mistake
after he had discard the first Xylene.
After the IPA from the two last alcohol extractions, SWIM only got 18g E, a 40% yield. If SWIM does one last IPA extraction, he migth get a few extra grams.
Now to the question, is it really posseble for the water in "undried" Xylene to steel so much E? Or does the E hide some where else?
TIA.
