Hi, 55 deg *C este necesar pentru evaporarea în vid a solvenților și a excesului de metilamină. Este o procedură opțională.
Sinteza mefedronei (4-MMC) din halocetonă în acetat de etil. Scala 1-10 kg.
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

3. The mixture is stirred until complete amount of 2-bromo-4'-methylpropiophenone (cas 1451-82-7) is dissolved.

my qustion is in video bro do this step after mixing water .but in method layer happen after 2-bromo-4'-methylpropiophenone dislove in ethyal cant understand this point
