Proovisin seda sünteesi teha ja see lõppes karamelli välimuse ja tekstuuriga. Kristalle ei olnud üldse. Kasutasin tablette, mis sisaldasid maisitärklist, povidooni, laktoosi ja magneesiumstearaati. Selle asemel, et lisada pillid mikrolaine vees, lisasin need etanoolile, siis aurutasin etanooli ära ja see oli sellise karamelli tekstuuriga. Seejärel lisasin karamellile pseudoefedriini sama palju vett, nagu retseptis öeldud. Pärast seda tegin nii nagu retseptis öeldud, kuid värvimuutus ilmnes kohe 1-2 tunni pärast 8-10 tunni asemel. Ootasin ikkagi 8 tundi, siis filtreerisin selle ja jätsin selle letile ja tahtsin lisada hcl, kuid ei saanud, sest ma ei olnud kodus ja lõpuks lisasin selle 3 päeva pärast segu filtreerimist. Ma lisasin 1,5 supilusikatäit hcl-i, mida ma püüdsin üle lüüa, sest mul ei olnud sel ajal ph-riba. Seejärel keetsin vedeliku ära ja jäi jälle see karamellilaadne aine. Proovisin seda atsetoonis ümberkristalliseerida, kuid see ei toiminud, see oli ikka veel karamelline. Mis põhjustas selle sünteesi ebaõnnestumise? Kas see on tablettide, ekstraheerimismeetodi, minu hcl lisamine liiga hilja või liiga vähese hcl lisamine? Või õnnestus mul see süntees ja ma oleksin pidanud lihtsalt laskma veel natuke kuivada? Palun aidake.

Could be the pills weren't extracted or properly enough. Or the final product was over acidified. I've never done this one as tina is better and reagents are more readily accessible.

I tried it a differen't time with proper ph management, I didn't extract the pills, I did it like in the synthesis, but when I evaporated the final mixture it was still caramel but when I added ethanol crystals came out and I separated them from the caramel and got like 2g of white crystals.

Chemical equation: 2 NaHSO₃ + MnO₂ → Na₂SO₄ + MnO + H₂O
the balanced chemical equation is: 2 MnO + 2 NaHSO3 + H2O → 2 MnSO4 + Na2SO4 + 2 H2O.
Freebase Methcathinone is soluble in Hexane and Methcathinone HCl is soluble in water. So Methcathinone can be separated from MnSO4 and Na2SO4 into the Hexane layer.
Sodium Hydrogen Sulfite.
Reacidification with Muriatic Acid (30% HCl Acid).

This reactions is noncense in inorganic chemistry!
MnO can not be formed in this reactions and especially in solution

This reaction proceeds differently depending on the conditions

In H2O more likely to formed Mn(OH)2
If solution acidified of H2SO4 in the reaction formed MnSO4
And complex compounds can also be formed

Cool! Methcathinone synthesis from Ehedrine.
