Thx Org for the references I've been reviewing them...
I'm 3/4's of the way through my 2.5" of patents I printed out, however some PM's cleared up the questions:
1.)precursor HCL salts do not affect the Pd/C - Pd/BASO4 reactions
2.) Catalytic activity is dependent upon the surface area of the Pd on the support. Reduction of your catalyst in H2 is not recommended due to large (>25A) pd crystals being formed. Formaldhyde reduction is preferred.
3.) Functional groups (aldehydes etc) on the carbon can wack the pd and cause large (reduced surface area) Pd crystals.
4.) Pd/C in Wizard's write up is 1 shot. Not recommended
5.) Pd/Barium Sulfate looks very good...experimental to follow.
The catalytic support carbon is on order and will arrive shortly... Preparation of ones own Activated Carbon has so many variables and requires such extreme temp/pressure gradients that controlling these variables is more complex than most synthesis's here. And you need a scanning electron microscope for pore size quality control. However I am going to try it anyway. There are several manuf. of Activated Carbon that have rather nice automated selection engines for your catalytic choices.
Various patent preparations use condensation of the Pd from Sodium salts and use of H2O2 to control crystal formation size. I will post a complete list of Useful patent refs after i've saved everyone the time by reviewing them.
I have completed the theoretical analysis for a MW reduction via BASO4 + AcOH + Am.Form. I'll run a microscale and report TLC results this week.
To assist in Orgk's request, here are some cites that our eurobee's might be kind enough to look up ( and translate) to assist. I believe they have the original method(s)
