Reaktorji za katalizator iz plemenitih kovin, ki se mešajo?

[CryoThio]

Ali je to sploh mogoče? Pod tukaj objavljeno povezavo o hidrogeniranju piše, da ni, vendar pa ugotavljam, da parr shakers niso na voljo v velikih velikostih, ki jih potrebujejo veliki psi na Nizozemskem. Ti dnevno proizvedejo na stotine kilogramov, parr shakerji pa, kolikor vem, tega preprosto ne bodo zmogli. Kljub temu so katalizatorji iz plemenitih kovin tam zelo priljubljeni, kar dokazujejo njihova lastna notranja poročila o trgovini z drogami.

Kaj se torej dogaja? Kako to, da veliki psi uporabljajo katalizatorje iz plemenitih kovin za proizvodnjo mdma itd., vendar navidezno ne uporabljajo parnih stresalnikov?

Pozdravljeni, iščem reaktor za 4cmc za 100 in 300 litrov je enak kot za 4mmc, vendar ga ne najdem na forumu, sem iz Poljske, če mi lahko pošljete povezavo do poglavja, ki me zanima, vam bom zelo hvaležen, reaktor je lahko domač

I honestly hope Parr type of hydrogenation bomb was out of your thoughts where it should stay unless you are with the heavy chemical industry. I highly recommend fluidised bed reactors such as catalyst filled columns kept at optimal conditions and recirculated if needed until full conversion, the small lab-scale setups are well constructed from an old HPLC where only the columns need to be prepared and can be switched back to analytical function. Of course a flow of hydrogen also needs to be provided so on the context of scale-up for this particular step I would use a multiple series of gravitationally oriented flow of liquid and inverse dispersal of super fine H2 bubbles that are absorbed in reaction and when they start exiting it indicates possible saturation of product.

H2 gas isn't the only possible hydrogen source in a Pd/C CTH type reaction, ammonium formate also works in some cases, I didn't say it's the best suited for your plans but there are many other approaches.
