O metanol pode substituir o etanol como solvente?

Yes, it's even better.

But the risk of toxic gases increases.

Esta redação é uma confusão total. Se o seguires tal como está, terás 10% de rendimento. Ou talvez menos.

1. A amálgama de alumínio deve ser preparada com antecedência, é um passo importante
2. Adicione o seu p2p, Metilamina à amálgama juntamente com isopropanol
3. Manter a temperatura da reação <30 graus
4. Com 40g de p2p e 40g de alumínio FOIL, obterá 100% de fuga :).
5. Adicionar NaOH/KOH antes de filtrar as lamas de Al/Hg, facilita o processo de filtragem e elimina o Al remanescente
6. E assim por diante...

Fiz antes em bidões de 200L, mas os de 100L também servem, e fiz uma reação em vaso.

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 a certeza quanto ao papel de alumínio, mas acabei por encher cerca de 2/3 de um balde com papel de alumínio arranhado/danificado (sem bolas), pelo que o peso foi esse.

No final, era demasiado papel de alumínio.
Rendimento; 12L com PH 12.

Na altura, com a metilamina, toda a gente sabe que existem melhores alternativas 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.
