Mõlemad töötavad ja mõlemad on head.

Hi Marvin
Great video and I have successfully synthesized 4mmc using this synthesis, thanks. Worked beautifully when acidified with hcl35 but using hbr48 turned out to be a disaster..is hbr not interchangeable with hcl for acidification of 4mmc in benzene?

C10H11BrO + CH5N → C11H15NO + HBr
Nagu võrrandist näha, toodab üks molekul 2-brom-4-metüülpropiofenooni ühe molekuli mefedrooni.
C10H11BrO : 227,0977 g/mol
C11H15NO : 177,2429 g/mol
227.0977/177.2429=1.28127953
Koefitsient on 1,28127953
See tähendab, et 100 g 2-brom-4-propiofenooni kohta saadakse 78,0469818 g mefedroonalust.

Mefedroonvesinikkloriidi mass suureneb 1,19 g/cm3 ja koefitsient on 1,27273446.
C11H15NO+HCl=177.2429+1.19=178.4329
227.0977/178.4329=1.27273446

100g(C10H11BrO)/1.27273446=78.5709849g(C11H15NO)
2-brom-4-metüülpropiofenooni reaktsiooni teoreetiline saagis oli 78,5709849g mefedroonvesinikkloriidi. Kuid tuleb arvestada, et teoreetilist saagist on raske saavutada, tavaliselt on kaotus 20%.

Ma olen leidnud 2-Bromo-4-Methylpropiophenone vedeliku tarnija, kuid ma ei tea, kuidas sellest alustada ja kui palju vedelikku peaksin kasutama, et teha 100g 4mmc. ma vajan mõningaid nõuandeid.

Ma ei lisanud atsetooni, vaid ainult MMC freebase'i benseenis ja tilgutasin 30% HCl-i pH 5,5 juures. Hapet lisasin aeglaselt. Kas atsetoon võib olla probleemiks? Unustasin, sest tavaliselt hapestan DCM+veega, seega atsetoon ei tulnud meelde. Kuidas sa pildil olevat ilu hapestasid? Tänan teid väga.
