"Place your wacker solution in the freezer for about an hour until it is cold, you should notice a very fine red particulate settled on the bottom of your container."
I tried this and it pretty much sucked. Very minimal palladium precipate even as low as -7c in for 8 hours.
"see you make it sound easier then it is when using a 20% naoh wash it causes the oil to reheat and form more waste and polymerisation"
What?! It doesn't heat up. Never noticed any temp climb here. Besides thats why you pre-chill your naoh mix before adding to the oil/toluene.
Man, I'm telling you, there is no comparison between the precipitate that you'll get between a naoh wash and and punk-ass bicarbonate wash. I need to do naoh washes, I don't distill at all. If i relied solely on salt and bicarbonate washes then I would get absolutely nothing in yeild. The 2 best chems I have found are in the order NaOH, KOH, EDTA. I imagine any strong base would work.
