Swims 2nd LWR-reaction has started.
He has lab grade i2 and RP. Extracted from european e.hcl pills...
He read here that the uasually contain l-ephedrine.hcl, but that it
could be used as psuedo in a HI reaction to create meth.
So he extracted the ephedrine from the pills using boiling IPA, and no
tetratraps etc cause the pills are just 6g of mass for 3 g of meth and
are from pakistan. I seriously doubt that they have same gak there as in
the US...
Anyway, postextraction weight seemed to match my predictions.
Got between 80 - 95% yeilds, pretty good i thought.
So, off to make the LWR going.
Added 10ml dH20 and 4 g LG RP to a 250ml RB flask.
Added 12g LG I2.
Smelled the HI forming.
Now i fubled a little, so it took me about 50 sec - 1 min to get all
the e.hcl in before i could mount the condenser with big assed balloon on.
Swim read that there was supposed to be bubbles all over the reaction surface
during the reaction. He observed his own, saw no bubbles. Feared that all HI was gone. Yanked up heat, oilbath now reads 125-128C. Bubbles can be observed but not over the entire surface at all times, but it bubbles ok, so he recons thats normal.
Now he wonders..
He has seen posts here that if psuedo is dirty he will get nothing
And if HI conc. is less than 57% he will get nothing.
So he figures of course to recryst. but is there any way to separate unreacted e.hcl and meth.hcl? He figures that it will follow in any recryst or wash he does...
Also, having never seen or done meth, how will he know that is is in fact meth
and not just e.hcl? or 20% meth and e.hcl?
Swim just wants a clean product, any suggestions?
Thanks for your time!
