Χρησιμοποιείτε συμπυκνωτή παλινδρόμησης και απορροφητήρα καπνών;

In a write up that most people are reading to do this leuckart with formamide and p2p specifically... what is the purpose of a 15 min reflux with 30% h2O2 with the reaction mixture after you have already done the first reflux with formamide and p2p. Does it clean up or oxidize something? I mean this is prior to the hydrolysis. I just can't think of what it would do. I mean most people do it without it but it was obviously added for a reason in a actual professional write-up.

Sorry, but I don't clearly understand about what "15 mix reflux" are you talking about? Can you be more precise. Refer to a step number.

It's not on these instructions. When making amphetamine after the first 24 hour reflux on a different set of instructions they would reflux for 15 minutes with 30% hydrogen peroxide and then go on with hydrolysis. What was the point of the peroxide?

I have no Idea about what "different set of instructions" are you talking and hence can't answer your question.

Έφτιαξα τα ισχυρότερα υπεροξείδια του υδρογόνου μου από 12% H2O2. Απλώς εξατμίσαμε προσεκτικά το νερό από αυτό.
Ζήτησα υπολογισμούς από τον βοηθό τεχνητής νοημοσύνης-ρομπότ στη χημεία. Είναι καλός στους υπολογισμούς, αλλά μην περιμένετε να πάρει σωστές απαντήσεις
από αλογονώσεις ή κάτι παρόμοιο...

Ακόμα δεν έχω δοκιμάσει την αντίδραση αλλά με καλή υδρολύση με KOH και στη συνέχεια με HCL θα πρέπει να δώσει υψηλή απόδοση, και φοβάμαι ότι εργάζομαι με h2o2 για να μην σχηματίσω εκρηκτικά υπεροξείδια και κατά την απομάκρυνση να μην εκραγεί

This questions are mainly regarding the actual chemistry behind the synthesis...
Why does one for the formation of the amine from the intermediate need H2O2 and HCl in the synthesis of amphetamine but only HCl in the synthesis of methamphetamine?
