Strontium Member posted 08-27-99 06:36 AM -------------------------------------------------------------------------------- Does anyone have any experience with the electrolytical reductive amination of a ringsubstituted-beta-nitrostyrene, in a solution of HAc+EtOH+HCl for the catholyte, and HCl (14%) for the anolyte? Cathode is a lead sheet and anode is a carbon rod. Current 0.7 A/cm2 Reduction time aprox. 12 hours. Sounds nice in theory. But what about the actual difficulties? Strontium Rhodium Administrator posted 08-27-99 10:44 AM -------------------------------------------------------------------------------- One of the biggest problem is to find a suitable cell divider, an ion permeable membrane to place between the anode and cathode departments. I don't believe a clay flower pot will do, as some sources (uncle fester) claims.

Wizard X Moderator posted 08-27-99 11:34 PM -------------------------------------------------------------------------------- Spend the money and buy a sintered glass frit extraction thinble or a Al2O3 porous cup. It will last for many reductions. Look at my web-page for a complete write-up. Strontium Member posted 08-28-99 08:46 AM -------------------------------------------------------------------------------- Hmm. OK! Anything else that might be harder than the theory? Has anyone done a reduction like this with a pre-goodie nitroethene or propene, and got a good yield of the goodie? Wiz. What's the adress to your page? Strontium Wizard X Moderator posted 08-28-99 08:24 PM -------------------------------------------------------------------------------- You will find it in my profile. dwarfer Member posted 08-31-99 03:54 PM -------------------------------------------------------------------------------- The clay pot will work for non critical separations such as merely making NaOH from brine, for example: and the sheep intestine's role (as secondary separator, making a 3 cell system) in real life is such that it in fact does have pores that allow ion transport and not molecules. In combination they work well enuff for the electroreduction entitled "new fester method": although I have no doubt that glass frit material will be better if you wish to specify your desired pore size. If you want to make one for about $3.00 and 1.5 hours invested time take a look at the D-VI machination at Villageidiot's (FJ's) website. Or leave your addy and I'll send you a picture. dwarfer DRedge unregistered posted 08-31-99 11:39 PM -------------------------------------------------------------------------------- works for moonshine a swifty in for all of ya! dehydrates the booze shine in there???
