Random Notes
« Reply #20 on: July 18, 2009, 05:33:41 PM »
I figured since this is a random experiment threed then I may as well add random notes that I have been keeping here and there within reason of course. Alot of this may not make sence to anyone you but ill attempt to doctor it here and there to make it more readable. Understand much was written in a haste long ago and where written for my eyes and not anyone elses so any questions or corrections feel free to ask.

discussion
----------------
1: product was a bright white when dried after some effort.27.5 grams it a little two high and makes me think that some bicarbonate contamination is in the mix because after a lose of NH3 and a
gain of Na there should be a net lose in the molar weight yet quantitive yeilds where observed.

2:lots of fizzing and very strong ammonia smell. It has come to my attention that the NaOH I was using was a mix of NaOH and KOH so the ratio will
be way to low for my liking so I will attempt another bicarbonate reaction.
After it had dried I added a very small portion of NaOH and the smell of ammonia became appearent so More conversion could be used because as it stands now it is a
mixture of sodium/potassium/ammonia nitrate.
After drying a small amount of NaOH solution was added and the smell of ammonia because quickly appearent so it it obvious that a total conversion did not take place.
Im going to slowly add more and dry and ad more and dry until i no longer smell NH3 from NaOH addition. Smells gone now but it has a hint of urinal smell

3: 2mm crystals precipitated and where dryed but there is some concern with H2O being traped within the crystal structure so i am going to grind it very fine and continue heating it.

Here is a easy way to do it with Mn(V)sulfate. A way I used many time!

1:First get some MnO2. You can buy it as "Manganese-Black" a pigment for cement and concrete. Thats about 70% MnO2.

2:Then put it in an equimolar amount of H2SO4 (100%) and heat it up. Make it really hot. (>200°C).

3:Let it be there for about half an hour. When I do this, I let The acid become so hot, that white steam comes out.

4:After that, let it cool down. You just have made Mn(V)SO4. It is soluble in 37% H2SO4 (battery acid) with a deep, chocolate like brown color.

5:After that put it 1:1 with the toluene in about 60% H2SO4 (enough H2SO4, so that nearly everything dissolves).

6:Heat (or cool) it to about 50-60°C and stirr it well. After 3-4 hours you will have mostly Benzaldehyd (in my cases about 70%)

7:Distill the Benzaldehyd/Toluene out by a simple steam distillation. (Just boil water out, until there is no oily layer any more)
  When you start boiling that stuff, the color of the liquid becomes sand-like. Thats because the rest of the Mn(V)SO4 breaks down to Mn(II)SO4.

And now the best: just put the liquid in a electrolytic cell (in the anode-part) and put some electricity through it, while stirring.
 The color will chance to chocolate brown once again, and you can use it again!!! About 6 times!

You've had some interest in the fentons reagent, I don't know if you already knew this or care at all, but according to a post by some newb over at SM, he says this reagent turn phenol to catechol. Take a look to: http://www.h2o2.com/applications/industrialwastewater/fentonsreagen...
You may have already even said it on this bored, but thought it might be of interest.

Wiki says,

Quote
Hydroxylamine can also be produced by the reduction of nitrous acid or potassium nitrate with bisulfite:

HNO2 + 2 HSO3? ? N(OH)(OSO2)22? + H2O ? NH(OH)(OSO2)? + HSO4?
NH(OH)(OSO2)? + H3O+ (100 °C/1 h) ? NH3(OH)+ + HSO4?

Sedits thoughts are, "Thats suppose to be KNO2 not KNO3"

But a spoonful of KNO3 was added to warm water. A spoon of Sodium Bisulfate was added.........Fuck bisulfite, bisulfite.... well that explains it somewhat. Hence the term random. I seen it, I tryed it, I read it wrong..

Oh well,

Anyway bubbles came up and im not quite sure what they where,

Any suggestions?

So only KNO3 and NaHSO4 were added together? Most likley a basic contamination from you KNO3, such as carbonate, etc. It is essentially a dilute solution of nitric acid with a bunch of salts, If you heat it up, I bet it dissolves some copper.

Yeh I think your right as a different batch of NaNO3 created differently did not react the same.



New experiment:

Some will understand my reason for doing this test......

1ml of Black Mangenese persulfate oxidiser was added to 1ml of HCl. Fumes appeared but its a bit humid so there where fumes from the HCl anyway. As soon as they where mixed though the smell changed from HCl fumes to what seemed like Hypo Chlorate fumes and the smell was strong. It appears that the Mn(IV)sulfate oxidiser is strong enough to oxidise HCl to Hypochlorous acid (HClO) quickly.

The solution after about 20-40 minutes changed from black to yellow and the smell of HClO appeared to drop to almost nothing which strikes me as odd because I would think the smell would persist is indeed HClO was still in solution.

Wow I did this exact same thing today!
I had my old nasty Mn sulfate/H2SO4 mixture, slightly purple mostly black looking, and I was trying to figure out if it was carbon I was seeing or what, since the epoxy, and some plastics had dissolved in it. I added NH4NO3 to it and heated, no color change. I then added a pellet of NH4Cl and the dark solution turned yellowish green with chlorine fumes. I thought that this was from the HNO3 form, and probably still is, but I noted the green color change as well, so the Mn, which must be in the persulfate form had to change into something I'm guessing.

Sedit, could you please write the continuation of this:

 Here your description ends, you obviously missed smth. Very interesting! Is H2SO4 concentration of 45% realy enough to produce ethylbromide? Methylbromide as well? Maybe even battery acid (37%) is feasible for something?  That is a great if alkylating agents can be dome OTC.

Concerning Mn "persulfate" (better to say Mn(IV) sulfate i suppose): MnO2 is a reagent used to produce chlorine with conc HCl, same seems to happens with Mn(SO4)2. MnO2 due to insolubility requires some heat and concentrated HCl usually, and Mn(SO4)2 is much more reactive. It seems you got Cl2O species there, they are considerably stable at high H+ concentration. If you want to make mostly chlorine gas, try to add much Cl- there (like NaCl). As for Mn(SO4)2 being a better oxydiser thats why it further oxydises chlorine to Cl+, that i suppose is not like that. Clorine easily disproportionates with water yieldind
HOCl + HCl, so there is no need to oxidize chlorine, it oxydizes itself. You Vesp probably observed same with NH4Cl

Wikipedia's KNO3 instead of KNO2 is obviously a mistype/mistake. No need to continue experiments with nitrate.

That one was pretty recent zz-zhuchila, Full experiment is here. Worked out well Ala getto.
http://127.0.0.1/talk/index.php/topic,32.0.html

Your all more then likely correct in that its oxidising Cl which in H2O like you said it yeilding the HOCl.
It will be easy enough to test as NaCl should yeild the same smell that I was getting. Vesp did you notice the bleach smell when adding the NH4Cl? Im still woundering though if Mn(SO4)2 is even the correct product of the electrosynthesis to begin with. Im starting to wounder if activated MnO2 is the real oxidiser in all of this because there is much black slug that forms when the ozone smell appears, see other threed for toluene oxidation as I was messing around with it a bit last night.


As far as the KNO3 is concerned, yeh Im not going to go any deaper into that as it would just be a waste of material. However I will play some more when I get some Bisulfite to test the correct reaction with.

Yeah I too have gotten a black sludge, but I figured this was carbon until it dissolved turning a yellow-green. I did smell chlorine gas, and it was strong. I did the addition of both NH4NO3 and NH4Cl while the solution was boiling.

I am going to get some of my liquid and heat it up with some ethanol today and see what color it turns. Hopefully the black junk will turn to a clear solution.

I was thinking that the Mn(SO4)2 was decomposing into MnO2 and MnSO4, since apparently the sludge is not carbon. This seems far fetched to me, because I don't see how MnO2 could form in such acidic conditions from the sulfate, or persulfate. I think now the Mn(SO4)2 just isn't that soluble in water, and it precipitates.

The black slug is suppose to be the Mn(IV). The smell of ozone though throws me off because I know that when Mn2O7 decomposes to O3. The smell of O3 is strong when the finished oxidiser is run cold.

Oh, solutions of just sulfuric acid and water produce ozone if they are in the right concentrations. That is probably happening, despite their being any Mn salts in there.

Just a bit bord so i decided to play with some nitromethane and a mixture of Nickle and copper salts made from a normal nickle coin with a concentration of something on the order of 25% Ni / 75% Cu.

Anyway the dryed salts where dissolved in H2O and HCl dripped in to Dissolve some oxides that where mixed in from prolonged sitting. Slightly heated to drive off HCl and then Some MeOH added. Fine bubbles started to rise and fear of them being Methylchloride I decided to leave this outside for some time followed with a hot water bath to try to remove any MeCl that may be there. I then added Nitromethane streight from the can (This is a random experiment threed get off my back youll get the goods later ;) ) and then added some Aluminum slivers cut from flashing.

It bubbled at an increasing pace and I left it still outside stirring for quite a while. When I came back the Copper had precipitated as well as a black slug presumably Nickle or Aluminum ... or both for that matter.

When all said an done I evaporated off much of the methanol and basifyed with a bit of strong NaOH solution. There was a strong smell of Methylamine.



Results:

The Methylamine could have withease been formed under acidic conditions thue dissolving metal reduction of aluminum so there is not much conclusion. I soon plan on getting some Styrene and pure Nickle salts to try a few more things with it such as condensation of MeNO2 with styrene and attempting to reduce to Phenylethylamine. If it does reduce the nitrostyrene to Phenylethylamine is should prove applicable to use on other simular substrates.

I'm waiting to see if this works on substituted nitrostyrenes (I see no reason why not).

knoevanagel style condensation of nitro alkanes onto styrenes?
i don't think it will happen.
condensation would be misnomer really it would be addition to the double bond.
never heard of nitroalkanes adding to double bonds you have any literature?

Yes sorry I ment Benzaldahyde + Nitromenthane but I had something on my mind that I have been discussing with someone else recently that involves a condensation of Styrene and Nitromethane.

Aluminum foil balls prepared for use in an amalgum a while ago was added to Potassium Nitrate, NaOH solution. Faint bubbling forms with no smell until the temperature runs to high then the smell of ammonia becomes extreamly strong as the exothermic runaway takes over. Aluminum reduces nitrates to nitrites under 60 degrees with Ammonia being the product if the temperature climbs to high. I have never heard of discussion of this being performed in a solely aq enviroment though.

My guess would have to be that the same principle could be applyed using Al in MeOH/NaOH + MeNO2 to bail methylamine out of the reaction mixture.

This will be toyed with later I guess. Easy enough to test just mix and wait then smell.

Seems like it might produce aluminium methoxide as well.
NaOH can work as a catalyst for aluminum to react with water, can't it?
I know I have read diluting solutions of sodium aluminate will precipitate aluminum hydroxide and regenerate sodium hydroxide - this is why it is so important to use a concentrated solution of sodium hydroxide when generating raney nickel from the alloy.

For producing nitrite you might find that you only need a tiny bit of NaOH, which could avoid a run away and prevent ammonia being produced.
If the Al(OH)3 precipitates, that could make purifying the nitrite pretty easy and might be one of the better methods of producing nitrite, as you'd be left with a mostly pure solution of the nitrite, plus a little hydroxide which could easily be extracted by crystallizing the nitrite out.

Tiny bit of NaOH and low temperatures it is Vesp... Work up to clear the nitrite from the aluminum compounds don't seem practical right now though so thats the current road block.

Now back to our currently scheduled ADD programing...........

pool EDTA metal chelating solution containing EDTA, Sodium metasilicate, limonene(IIRC), and polysorbate. When Muriatic acid is added to it in equal portions needle like crystals start to precipitate and the smell changes from citrus to the smell of cedar wood. This has me more interested then anything considering I love the smell of cedar. I would have to assume at first guess that it has to do with the Limonene undergoing some form of reaction leading to the smell of cedar. Anyone have a guess as to what?

Also what do you think these crystals(about 1mm -2mm long) are? Are they the hydrolysis product Im after(EDA*(HCl)2) slowly precipitating in this mixture of crap? That would be real nice lemme tell ya, but.... If I learned anything from organic chemistry its if something seems to work with ease you done did it wrong.....

A mixture of NaNO3 and HCl was mixed up and it was obvious excess HCl was used although I have no idea how much.

Denatured Ethyl alcohol was added to this at ambiant temperatures of 70 degrees F. It started to produce fine bubbles. The smell of Acetaldahyde becomes strong after only ten minutes or so.

The reason for this test was to attempt to reproduce a form of this experiment by Magpie on the oxidation of diols to there carboxylic acids. I never applyed any heat and the small amount that was created went away fairly quickly. I have not noticed any trace of the Acetic acid smell I was looking for so I am a bit bothered by this and excited at the same time. I feel that Acetaldahyde is just to damn volatile to form the acid without a good reflux going.

Ill say more but I gotta go right now.... Ill prob just edit it into this post..............
