Vai metanols var aizstāt etanolu kā šķīdinātāju?

Yes, it's even better.

But the risk of toxic gases increases.

Šis uzraksts ir pilnīgs haoss. Ievērojot to tādu, kāds tas ir, jūs iegūsiet 10 % jeldu. Vai var būt mazāk.

1. Alumīnija amalgama ir jāsagatavo iepriekš, tas ir svarīgs solis.
2. Pievienojiet p2p, metilamīnu amalgamai kopā ar izopropanolu.
3. Uzturēt reakcijas temperatūru <30 grādu
4. Izmantojot 40 g p2p un 40 g alumīnija FOIL, jūs iegūsiet 100 % izplūšanu :).
5. Pirms Al/Hg nogulšņu filtrēšanas pievienojiet NaOH/KOH, tas atvieglo filtrēšanas procesu un iznīcina atlikušo Al.
6. Un tā tālāk...

Es iepriekš darīju uz 200 litru mucām, arī 100 litru mucas ir piemērotas, un veicu viena katla reakciju.

350-400 g dzīvsudraba uz 10L b (400 g ir patiešām daudz agresīva), 15L metilamīna 40% un tad apmēram 30L metanola.
Par foliju neesmu pārliecināts, man beigās bija sanācis, ka 2/3 spaiņa pilns ar saskrāpētu/bojātu foliju (bez lodītēm), tāpēc tas bija tāds svars.

Galu galā folijas bija par daudz.
Iznākums: 12 l pie PH 12.

Atpakaļ ar metilamīnu, visi zina, ka tam ir labākas alternatīvas, strādājot, piemēram, ar 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.
