O metanol pode substituir o etanol como solvente?

Yes, it's even better.

But the risk of toxic gases increases.

Esta redação está uma bagunça total. Segui-lo como está lhe dará 10% de rendimento. Ou talvez menos.

1. O amálgama de alumínio deve ser preparado com antecedência, essa é uma etapa importante
2. Adicione seu p2p, metilamina ao amálgama junto com isopropanol
3. Mantenha a temperatura da reação <30 graus
4. Com 40 g de p2p e 40 g de alumínio FOIL, você obterá 100% de fuga :).
5. Adicione NaOH/KOH antes de filtrar o lodo de Al/Hg, pois isso facilita o processo de filtragem e elimina o Al restante
6. E assim por diante...

Fiz antes em tambores de 200L, tambores de 100L também servem, e fiz uma reação em um pote.

350-400 gramas de mercúrio em 10L b (400 gramas é realmente muito agressivo), 15L de metilamina 40% e depois cerca de 30L de metanol.
Não tenho certeza sobre o papel-alumínio. No final, eu tinha feito cerca de 2/3 de um balde cheio com papel-alumínio arranhado/danificado (sem bolas), portanto, era esse o peso.

No final, era muito papel-alumínio.
Rendimento: 12L com PH 12.

Naquela época, com a metilamina, todos sabem que há alternativas melhores para isso quando se trabalha, por exemplo, com 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.
