Hello there....

I have a some sort of strange question.
Look at the link below and please tell: What's wrong with this picture?

img838.imageshack.us/img838/5196/emailca.png

I mean by no standard can i for a long time call myself chemist, but one has to be blind not to shit in ones pants when seeing this molecule and that it will start seeling soon. Cause the hg-part just gives me chills.
Thing i that the forum where the news of this soon coming attraction, knowone knows anything about chemistry.

So would someone with knowledge, explain to me if it is a ok compound(which would make me question things like gravity, Sheldon Cooper and Neil Young) to ingest, or if it is a cruel joke on those dummies on that forum, explain if it even is possible to make the compound and of course in regard some dumb fuck has done it and now unscrupulously plans to sell it to those desperate poor devils...
I will of course pass on the info so no young desperate kids try this before we know what it is, the kids seems to not bother with what they ingest as long as it gets them an altered mind of any kind.


Thank you on beforehand
Bis zum bitteren ende

Its a practical joke and I have a gut feeling the person who made this has poor understandings of the chemistry of organomercury compounds as they are always divalent i.e (Hg)R2.

It may take a long time:

Flashlights have been used to detect the layers separating ;) There will probably bee some losses due to the Cannizarro reaction  :-X The end results from the effort applied  8)

many thanks lugh. You are an invaluable resource to this community.
dumped in a bunch of dH2O, shook, and left it. flashlight, or more just holding at proper angle gave sight to layer separation.
There was DEFINITELY a reaction; Cannizarro we now know...
And there will surely be loses. Just washed the orgs with the appropriate NaOH/H2O solution. Started out with 156 gm safrole, presume to have about half remaining.

thanks again lugh!

Now remember reading somewhere that 500 ml flask is not big enough for the BS Al/Hg Amalgam. That was way before a beaker even gleamed the eye, and thus another lesson learned the hard way. Uggg...
Are folks tossing the Aluminum into the coffee grinder like Dr Gonzo's photo essay. Realize that its not the same reaction, just curious if the wadded up foil would help this one.

will keep you posted on the end results from the "Cannizarro-ized" ketone

it has been a very very very long time, but this smell is oh so reminiscent of the days long gone past of the assistant work one did with the crystal makers  way back.

the "significant other" said tonight at dinner:

"what were you doing today? It smelled like a dog in heat"
one  does believe that is a new, highly relative, description  not heard as of yet.

they all talk of cats...blah ;)

can the reclaimed IPA from brightstar STEP 5 bee used again in future "step 5's" or is it tainted with HG, etc?

don't sign in there often, thank you.

So after a hard days night, ended up the a single gram of "product"

not exactly sure where the major loss happened.

< 5mg were consumed in the clean up process and pretty sure  it's psychoactive. sensitive system and definitely rose above baseline.

applying much effort my man, much much effort.

thanks as always.

Can somebody provide an arrow pushing diagram of the reaction between Benzaldehyde and Nitroethane to form P2NP? I'm assuming that it is some kind of addition-elimination reaction, but I can't figure out exactly how it works. Why is the primary amine necessary? Is it to pull off the proton of the aldehyde? Thanks.

No diagram, but as I recall: the protons geminal to the nitro group are acidic, so nitroethane can be deprotonated by the rxn conditions, usually using acetate as a base. The nitroethyl anion is then electrophilically attacked by the carbonyl group in an aldol addition, forming a nitroalkanol. The other proton geminal to the nitro group is again acidic in the nitroalkanol, allowing it to deprotonate again, but this time the negative charge allows the alcohol oxygen to eliminate as a hydroxide ion, effectively losing H2O to form a nitroalkene. In the presence of a lot of heat and water, the reverse reaction occurs, releasing nitroethane.

stuff

The ordinary name for a reaction like this is alkene arylation.  The textbook example of an alkene arylation is the Heck reaction. The Heck reaction has here two problems for you: it is anti-Markovnikov and requires a palladium catalyst. The thing is, most such arylations are anti-Markovnikov.

The Friedel-Crafts arylation of alkenes protonates the alkene to form a carbocation intermediate. Unfortunately, this means that allylamine is right out, because the carbocation will react with the amine faster than with the ring. The basic trick is to protonate the alkene with a really strong acid.

http://www.orgsyn.org/orgsyn/orgsyn/prepContent.asp?prep=cv4p0702 <-- example of said reaction

Now, allyl bromide, on the other hand, could be just what you're looking for. Add to it a Delepine reaction and you might have yourself a tek. Though, pay attention: the catalyst is H2SO4, not AlCl3.

hey everyone!!!
dumb question, MAYBE! hehe

is there any way of determine the percentage of 2 liquids mixed together with diferent density? diferent volume
i know that if the 2 liquids were added or contain the same volume each, its easy, add both density and divide by 2..... but what if the volumes are diferent?

also on the density, its known that density varies according to temp, BUT for example a loved ketone had the density of 1.2g/ml, BUT the density of pure ketone its only reach this weight when its freezinh cold like a viscou oil. why this happens? means that freezing temprature its the "living" condition for this molecule? how its this determined, i thou every density was at room temp 25 degrees or so.

well if someone could just lightn up this soul hehe
peace everyone

You have to be much more specific because without knowing the properties of the two chemicals in the mixture it makes it super hard to answer your question.

I know for determining the proof of alcohol they use a hydrometer that can tell you since H2O has a known density any alteration of said density is caused by EtOH.


Please tell more about the two substance.

You can calculate the percentages using algebraic methods with a pencil and paper   ;)  You can also use computer software for the same purpose  :-X  It's rather obvious you need to spend more time studying basic mathematics until you understand it  ::)  The end results from the effort applied   8)

Will fractionally distilling isosafrole epoxide destroy it? i.e. will the heat applied break it down?

If one wants to make a bit of sulfuric acid.

Thought about letting Sodium bisulfate (NaHSO4) decompose in a excess of alcohol, ethanol or rather anhydrous propan-2-ol.
Did not find anything about this except this: en.wikipedia.org/wiki/Talk%3ASodium_bisulfate

Is it this easy?

*Blend the 2 components.
*Let them stand until done. -How long is that?
*Fish out the formed Sodium sulfate.
*Then either -let the remaining alcohol evaporate or
                     -Distill of the alcohol for later use elsewhere.
Voila - Sulfuric acid at damn near tech grade

If this is correct....
Should one let there be some water present or try to go anhydrous with both the NaHSO4 and the propan-2-ol. When Sodium sulfate forms in solution it would then suck in some(all?) water present because of its hygroscopic nature. The reason for this question is that the source of 4s NaHSO4 would be a type of Ph- where its obviously dissolved in water.
Is there any safetyaspect lacking here (danger)?
What if one used denatured alcohol? Would that Denatonium(bitrex) fuck with anything?

Would the following be correct?
2 NaHSO4 + C3H8O/C2H5OH ---->
H2SO4 + Na2SO4 + C3H8O/C2H5OH
