Vai tas vispār ir iespējams? Zem šeit ievietotās saites par hidrogenizāciju ir rakstīts, ka nav, tomēr es konstatēju, ka parr kratītāji nav pieejami lielos izmēros, kādi nepieciešami lielajiem suņiem Nīderlandē. Viņi dienā izdala simtiem kilogramu, un parr kratītāji, cik man zināms, to vienkārši nespēj izdarīt. Neraugoties uz to, dārgmetālu katalizatori tur ir ārkārtīgi populāri, par ko liecina viņu pašu iekšējie ziņojumi par narkotiku tirdzniecību.

Tātad, kas no tā izriet? Kā tas, ka lielie uzņēmumi izmanto dārgmetālu katalizatorus, lai ražotu mdma u. c., bet, šķiet, neizmanto par kratītājus?

Sveiki, es meklēju reaktoru 4cmc 100 un 300 litriem ir tāds pats kā 4mmc, bet es nevaru to atrast forumā, es esmu no Polijas, ja jūs varat nosūtīt man saiti uz sadaļu, kas mani interesē, es būšu ļoti pateicīgs, reaktors var būt mājās gatavots.

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.
