¿Es esto posible? En el enlace sobre hidrogenación publicado aquí se dice que no lo es, pero me parece que los agitadores parr no vienen en los tamaños grandes que necesitan los grandes de los Países Bajos. Producen cientos de kilos al día, y los agitadores de parr, que yo sepa, no sirven para eso. A pesar de ello, los catalizadores de metales preciosos son muy populares allí, como demuestran sus propios informes internos sobre el tráfico de drogas.

Entonces, ¿qué ocurre? ¿Cómo es que los peces gordos utilizan catalizadores de metales preciosos para producir mdma, etc., pero aparentemente no utilizan agitadores de par?

hola, estoy buscando un reactor para 4cmc para 100 y 300 litros es el mismo que para 4mmc pero no lo encuentro en el foro, soy de polonia si me podeis enviar un enlace a la seccion que me interesa os estare muy agradecido, el reactor puede ser casero

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.
