Reaktorer til ædelmetalkatalysatorer, der rører sig?

[CryoThio]

Er det overhovedet muligt? Under hydrogeneringslinket her står der, at det ikke er muligt, men jeg synes ikke, at parr shakers kommer i de store størrelser, som de store hunde i Holland har brug for. De producerer hundredvis af kilo om dagen, og så vidt jeg ved, er det ikke noget, der kan lade sig gøre med parrshakere. Alligevel er ædelmetalkatalysatorer superpopulære derovre, som det fremgår af deres egne interne rapporter om narkotikahandel.

Så hvad sker der? Hvordan kan de store hunde bruge ædelmetalkatalysatorer til at producere mdma osv., men tilsyneladende ikke bruge parr-shakers?

Hej, jeg leder efter en reaktor til 4cmc til 100 og 300 liter er den samme som for 4mmc, men jeg kan ikke finde den på forummet, jeg er fra polsk, hvis du kan sende mig et link til det afsnit, jeg er interesseret i, vil jeg være meget taknemmelig, reaktoren kan være hjemmelavet

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.
