Il metanolo può sostituire l'etanolo come solvente?

Yes, it's even better.

But the risk of toxic gases increases.

Questo documento è un pasticcio totale. Seguendolo così com'è si otterrà un risultato del 10%. O forse meno.

1. L'amalgama di alluminio deve essere preparato in anticipo, è un passaggio importante.
2. Aggiungere il p2p, la metilammina all'amalgama e l'isopropanolo.
3. Mantenere la temperatura di reazione <30 gradi
4. Con 40 g di p2p e 40 g di alluminio FOIL si otterrà il 100% di fuga :).
5. Aggiungere NaOH/KOH prima di filtrare i fanghi di Al/Hg, facilita il processo di filtrazione e uccide l'Al residuo.
6. E così via...

Ho fatto prima su fusti da 200L, vanno bene anche fusti da 100L, e ho fatto una reazione in vaso.

350-400 grammi di mercurio su 10L b (400 grammi sono davvero molto aggressivi), 15L di metilammina 40% e poi circa 30L di metanolo.
Per quanto riguarda la lamina non sono sicuro, alla fine avevo fatto 2/3 di un secchio pieno di lamina graffiata/danneggiata (senza palline) quindi il peso era quello.

Alla fine era troppa lamina.
Resa: 12 litri a PH 12.

Per quanto riguarda la metilammina, tutti sanno che ci sono alternative migliori quando si lavora con, ad esempio, Al/Hg.

When you say the Al amalgam can be made in situ does that mean one doesn’t have to wash & decant the HgCl from the aluminum before introducing the p2p + methylamine mixture? The HgCl can be left in the flask while reduction happens and will be extracted out later during product purification?

I'm currently experimenting with al/hg and wanted to scale the synthesis. I asked myself the question of whether it is absolutely necessary to use a capacitor? I suspect it is needed to keep the methylamine and solvent (methanol) in reaction vessel. But would it be possible to compensate for methylamine loss with a new methylamine-methanol solution?

Perhaps an excess of methylamine was used, not much, just to compensate
Add an amount of water
Keep the temperature no more than 60 degrees and you will be fine

I have heard of success with nitromethane, but the yields are lower.
