Hello there fellow Do-bee's. I wish to relate to you all this mad lucid dream that I have had which is recurring just before weekend's(snigger).
It started of with me reading a post at the hive "new festering method" or something like that (funny how you cant always remember the trivial bits of dreams only the real important stuff) and deceided to do some more research which pointed me in the direction of metal merchant's . This is where the dream got ugly and turned into a nightmare as Pd is very hard to get as a metal in plate or coin form 'down under'. It was so scary I almost woke up, but luckly, Merck Twelfth came to the rescue by informing me that Ag has very similiar property's, some which are better than Pd, namely a lot less reactive to H2SO4.It also can occlude H (not as much as Pd)but we don't really want to heat it up red hot to absorb H now do we? So bearing this in mind a trip to metal merchant was conducted and 54 gram's PURE FINE SILVER (not sterling) was purchased for the measly sum of 51cents/gram, in the shape of 75mm X 54mm X 1mm.(approx). 2 strips were cut from it one 10mm X 54mm one 15mm X 54mm. The 10mm bit was spot welded to the corner of the large remaining strip of 50mm X 54mm the 15mm strip was folded over on its self and the corners rounded off to remove sharp edge's.This was used in place of the lead bit.The next bit of dream was also a bit nightmarish for a while but also came good.Let me tell you about it. I went to purchase some BRANDNAME lamb gut condom's as per fester dream but after much fruitless searching I was informed by some dim-wit secretary that these condom's are not imported 'down-under' as they cannot make them big enough for Aussie condition's (just call me John Holmes) so the local butcher was conned into selling me a metre of lamb gut for 50 cents /metre. Bargain.So, with all the neccesary equipment,(plus some, Hi yanky girl's) a chemist sold me 70 X 60mg d-Pseudoephedrine tabs which followed me home , singing 'Mary had a little lamb, little lamb'(wierd dream,and it gets stranger).
So , the next thing I remember was i was extracting the right stuff outa the tabs (see many other post's on this dream)and vacumm filtering to yield 4.15g's(after drying) of precursor. This was pretty good recovery so maybe there is a little more than 60mg /tab in those cheap tabs (chemist's own brand for you Aussie hack's)
This was esterized using the procedure in the festering one's dream with 28 ml 100% ethonoic acid and 12 drops conc H2SO4 added after all was dissolved. This was water heated as per instructions. While this was happening,20 ml H2SO4 was added to 400ml DH2O in a 1 Litre beaker with the Ag plate lying flat on the bottom.This was used as some little voice in my head said 'Hey you dont have a mag stirrer so why don't you use the action of the rising liberated gas to stir the lot up' As I have read, little voice's in your head in dreams are your higher self telling you to do something that is correct so I went with this thought.
Mary's little lamb's gut was washed thoroughly in 30% sodium chloride solution and rinsed in DH2O and a double sheep shank not was tied in the end to seel it . It was then tested for no leak's (did'nt want my ester getting pregnant)and the preceding piece of Ag folded strip was put into it with a alligator clip attached with wire.
Another alligator clip was connected to the big piece of Ag and the wire fixed to the side of the beaker.The esterby this time had been steewing for 'bout # hours , so it was time to anodise the Ag which was done with 3 Amp's 1 min with lots of O generated.Polarity was reversed as per instruction's and left to sit bubbling away for 15 min's.
A constant source (variable) was quickly constructed using a LM317 with a 5Watt 50 ohm variable resistor hooked up between the adjust terminal and the Vout with the positive voltage going in to the Vin terminal (der) and the output taken from the Adjust terminal to give an adjustable I of between 25mA and 2A. calc's were done which told me that this cell would have a Resistance of approx 4 Ohms which when calculated to the fester formula gave me a power output of to much. Namely, 54mm X 50mm= 27 square cm X 50 mA/cm = 1.35 amps.
1.35 Amps squared = 1.8225 X (resistance) 4 Ohm's = 7.3 Watts ( joule/sec) so I think to self if 1joule raises 1 cubic cm water 1 deg then this thing (cell) is gonna get warm.Using 3000 coulums/gram I needed 3k X 4.15 grams = 12450 Coulumbs So 12450/1.8225 = 6831 seconds/3600 = 1.89 hours. So a decision was made to limit I to 800 mA for 4.33 hours. (12450/.8 = 4.33 hours.)So the whole thing was set up and 50% ester mix was added and reacted for 1.4 hours and then the second half ester was added and left to react for the remainder of the time.The mix was a turbulent mix of gas and liquid with no need for a mag stirrer with a white gassey look/colour to it. Th voltage across the cell was measured to be 3.120 Volts (Fluke 12). So 3.120/.8A = 3.9 ohm's, very close to calc's. The fluke 12 has a voltage / time recording function for maximum minium on it and I am in the process of charting it as I have had this dream 5 time's now and have some good stat's.
Anyway , back to the main dream. After the time had run out, the mix is observed to have a very slight yellow ting to it (all 5 time's) I do not think that this is because of the condom, but something to do with the sulphuric acid and hydrogen gas making some sulphur type thingys as a faint Hydrogen sulphide smell is present during the reaction process.The mix is washed in Pert Eth (my preferred solvent) 2 X 200ml basified with NaOh as is customary and crystals recovered with Bubbling HCl. For all you busy B's who have trouble with this tech, try pulling it through you final wash with an aspirator ( you know, HCl gen(sealed),hose, wash container(sealed)aspirator, sink,)on a very low vac just enough to bubble.Stuff is washed evaporated as is customary and dried. Mine come's out as lovely crystals (white with the faintest yellow tinge) which melt at 174-176 deg C.Yield for 4.15 g start in first run was 2.35 grams up to the best so far of 3.30grams(80%)approx. Hope to improve these through trial and error.
I have recently read of a Wizard X improved dream's and intend to incorporate these vision's as the theory sound's solid.
The basic concept here is to reduce C10H15NO to C10H15N by hydrogenation. As far as I see it how we hydrogenate it is erelevant as long as it work's, right?
Anyway, then I woke up, So that is the end of my dream at the moment.

Anyway, I got my self a purty 1oz silver ingot that measured 50mm x 29mm. So I figured I'd leave about 1cm clamping room thus taking my measurments down to 40mm x 29mm.

Now that's explained, here's calcs. I came up from here (based upon Uncle Fester's and AbSoLuTe's work)...
40mm x 29mm=11.6 square cm x 50 mA/cm=.580 amps squared.
I then squared(?) the .580 which gave me .3364 Amps (this boggles me, but I'll say something about that later)
Anyway, .3364 x 4 Ohms(Hypo.)=1.3456 Watts (joules/sec)
Dreaming along, I figure that 2 grams will go safely into this and plan on 6000 coulombs.
6000/.3364=17835.9/3600=4.9hrs
Or since I'm not sure if my current regulater can do a single mA at a time (but rather in increments of 10) I figured:
6000/.330=18181/3600=5.05hrs

Okie, on the Amps squared part up there, I found it strange that my amperage actually went down. Sure, this seems right mathmatically but electronically I wasn't sure... This is about the only part in this I'm not sure on.

But anyway, if one of you smart people around here could check this out (you know, some dream analyzing ;-) ), I'd like to see if my calcs are on.

Just use a 12v auto battery, and inline with the circuit use a headlight dimmer, or any other rheostat (inline=series)and a couple of 10ohm 20watt power resistors so you can tap the power at different points along the circuit and fine tune output by adjusting the rheostat.

Also...Electronics Now has a couple of great articles on building your own PS for use in electrolysis or electroplating/forming. Try an excite web search for "electrochem" and surf away.

I never trusted the condom, and that's one of the reasons I like having a three cell system, although I'm testing the condom by itself this weekend, but with elaborate care of it's punyness.

In rereading your notes, it impacted me that you used actual sheepgut rather than the condoms: are they any sturdier?? Sorry, not being Aussie, I just do not have a lot of experience in sheep slaughtering!

I have been up to my elbow in sheep pussy, however, in lambing processes.

So should I go with the little voice in my head saying."The mag stirrer is completely out of the scene now on this rxn,just throw a .999% piece of Silver plate or a Silver dollar in the bottom of the beaker"?

Thanks

Avoidance of the spark is all that is necessary.

Your the wiz (from what I see) at the electical math calc's. So if you have time could you do me the numbers when using two silver dollars w/no cell divider. 12 volt/6amp DC w/inline reostat power supply.
First run w/3grm.
12v 2A four hrs.
Only got partial conversion (40%yeild,short crystiles)
I know I'm getting close.

Many years ago I had Electricl schooling but some where along the line I've lost my calculator (and a few brain cell).Most of my schooling was with High voltage distrabution and motor controls so I don't think this is to far beyond my understanding. Any help will be returned with good Karma to be sure.

As regards Wixard x'x comments about avoidance of exposure to the oxygen in the air, that is one of the benefits of the D-series.

The filled cathode chamber has no exposure to any gasses other than H2.

The anolyte has both O2 AND H2, (and some SO4- I presume), but who cares since it does not react.

Avoidance of esterification can be presumed with the palladium cathode and under pressure according to my chemist guru friend: yields uncertain, however.

A tremendous amount of effort is going into trying to do this with acetic rather than GAA. Is it tough to get elsewhere?

Here on the left bank it seems to be not so difficult.

Thats a switch!
