To sem našel na ruskem forumu, po njihovem mnenju 100-odstotni bromoketon reagira v 7 urah pri 30 stopinjah Celzija

Avtor Linx (prepovedano) informacije niso zanesljive. Reakcija v diklorometanu traja v povprečju 2 uri pri 30 stopinjah.

Če nimam acetona ali IPA, ju lahko nadomestim z drugim alkoholom, kot sta metanol ali etanol?

Alkoholi morajo biti dobre kakovosti, da se prilegajo. IPA je najlažje dostopen. Tudi metilni in etilni bi morala ustrezati, vendar je pri njih težje najti ustrezno kakovost.

Slišal sem, da ljudje po aminiranju kasneje sperejo z vodo NaOH, je to potrebno?

Alkalije lahko uporabimo med aminiranjem za sprostitev metilamina iz metilamin hidrobromida, pri čemer je pomembno, da uporabljamo alkalije v pomanjkljivem stanju.
Tako boste prihranili metilamin.
Alkalija prispeva k pojavu stranskih reakcij, v reakciji ne sme biti v prosti obliki.

Kako malo acetona mora biti, ko dam HCl? ali je bolje dati malo bazi ali HCl zmešati z acetonom

Najprej pozdravljeni! 1:1 do 1:4 (HCl:aceton). V kislino sln dodajte aceton.

Kako dolgo traja raztapljanje 2-bromo-4'-metilpropiofenona v DCM?

Pri delu z 2 bromo 4 metilproiofenonom bi lahko raztopili 1 : 3 z DCM in začeli metilacijo s 40 %, ali sem tu kaj spregledal?

Prav tako se mi zdi, da so mnenja glede temperature, pri kateri poteka metilacija, deljena. Prebral sem, da naj bi bila temperatura 32-36 C, pri čemer naj bi se raztopina mešala 2 do 4 ure.
