18gr of Palladium on Carbon were prepared using following methode:
- 1,7 gr PdCl2 in 2 ml 31% HCl and 20 ml dH2O are heated for 15 min at 80°
- 20 gr activated carbon are heated with 450ml H2O and 15ml 31% HCl for 2h; the carbon is filtered off.
- the PdCl2 solution is added to 30 gr sodium acetat trihydrate in 200ml dH2O in a 500ml Flask
- the washed carbon is added to this solution
- hydrogenate the mixture for 3 hours, using a hydrogen generator producing 1mol of H2; don't forget to stir vigorously
- when the hydrogenation is complete and the carbon settles down you should have a colorless mixture with the catalyst at the bottom
- filter the carbon , wash it with 4-5*100ml dH2O; dry the catalyst at 50°
- I got 18gr (my filter methode wasn't good, use only glass no plastic, easier to clean) of 5% Palladium on Carbon. |
