Metamfetamiin efedriinist joodi ja punase P abil

Miks te kasutasite dcm, kas seda saab teha ilma dcm-ta? Samuti ei ole see natuke palju, et kasutada 12g I2 6g efedriini jaoks?
Millises etapis tekiks fosgeen?
- By hacke8
See ei tekita fosgeeni. Tekib fosforvesinikgaas, kui see on üle 130. Olge sellega ettevaatlik.
Kas keegi oskab mind linkida ühe poti meetodi juurde, kust ma saan kõik materjalid isiklikult. Idc kui ma ainult lõpuks mõned määrdunud met lihtsalt otsin projekti, kui naine on nädalavahetusel linnast väljas.
Nimekirjas on NH4Cl ja H2SO4. Kus täpselt neid sünteesis kasutatakse? Tänan vastuse eest.
Kas ma võin kasutada diklorometaani asemel ksüleeni?
- By GhostChemist
if o-xylene this is bad idea (B.P. 144C)
better petroleum ether, diethyl ether, benzene, toluene etc.

Kui ma lisan vaba aluse valmistamisel vett ja hcl, et hapestada vaba aluse, eraldan veekihi ja aurustan vee täielikult, kas lõpuks tekib sool? Teoreetiliselt ei ole vesinikkloriidi vaja?

When the free base extracted with DCM, you can use aqueous HCl for obtain salt after evaporation
can phenylpropanolamine be used instead of ephedrine in this synth?
- By William D.
Yes. If you have a supplier, send me a DM. The only problem is that the yield may be less than with the methylated version.
Swim had done this "red, white, blue" process with 6g E, 6g I, 3 g Rp and a couple of mls of D-H20 in a heat proof Corona beer glass bottle as a RXN vessel, a rubber stopper with airleak-proof connection with 5 foot tubing vertical and a punch balloon as a condenser, used a portable rice cooker & sand bath as heat source ~100-120C for 24 hours
Long Wet Reaction
Off heat to cool. Add 100 ml D-H20 . Filter Rp (**WASH OUT THE RP WITH HOT ACID, HOT ALCOHOL, HOT ACETONE, lukewarm water** good as new)
Add NaOH base solution till pH 12 A WHITE SLURRY WILL APPEAR
Extract with a NP fuel several times
Wash NP fuel/chilli with baking soda solution and then a D-H20 wash
Dry with drying agent for minutes and filter
Get a shot glass of D-H20 and drop 2-3 drops of HCl (or sulfuric acid) in it. Put this shot glass water with the NP/chilli and shake
Repeat several times
Extract water/chilli and evaporate on LOW heat
Speed a few hundred milligrams but good
* Swim got a VERY small percent yeild doing this method
Why did swim with 6 G of pseudoephedrine ended up with just a few hundred milligrams of speed ?!

Can I do this synthesis at 140 Fahrenheit for 48 hours and get the same result ?

We have not conducted these studies
Perhaps in the future we will receive these data and publish them
If you can carry out this synth at your parameters do it and present results
