8. Tämän jälkeen seos kuumennetaan 55
videossa sanotaan selvästi, ettei tarvitse lämmittää. ja tässä joku kirjoitti, että sitten lämmitetään mitä jos seos saavuttaa itse lämpötilan korkeintaan 65 °.

Hei, 55 astetta *C tarvitaan liuottimien ja metyyliamiinin ylijäämän tyhjiöhaihduttamiseen. Se on valinnainen menettely.

Stage 2
4.
The stirring is stopped. The reaction mixture is left for layer separations. A bottom layer is drained through a bottom reactor tap.

I'm asking ethyl acetate is light solvent and 2b4m is heavy so why we need to drain bottom layer
If we drain bottom layer then only ethyl acetate left in flask
Help me on this plz plz

Hello, I edited the write up. You should separate layers at step 7.

2-Bromo-4'-methylpropiophenone
2-Iodo-4'-methylpropiophenone
These are two different 4-MMC precursors. Please, look through the Methcathinones section topics before ask next question!
