Aluminium amalgam (Al/Hg) summary

[ASheSChem]

Do you know for sure gallium does not work? I was looking to explore less toxic materials.

Mclssmxxlno not sure at all, i'm a noob
but I never read that there were substitutes

ASheSChemI’m gonna give it a try and report back if I can find some.

 

[mixxxman]

no. it will doesn't work... "why ?"

cause what is the element used in this reaction, is the aluminum !
the works of the mercury it's to create a amalgam. and by this way take off the lay of "alumine (the natural oxidation from the air on aluminum")

-for others ways to a amine is :

*LiAlH4 (Lithium aluminum hydride), less toxic, pretty unstable/ hard to find.... easy if you are a professional cause is one of the easiest reduction.

*or the couple Zn/Ni but i have tried this method


if someone else has other information should be nice to share it here as well.

MclssmxxlIn your place I would simply test with a small load if you have gallium available and report the result here.
Gallium forms an amalgam with aluminum just like mercury and produces hydrogen, but there are also some differences at the electron level that make mercury impossible to replace with gallium completly.

juste for the beauty; a little lovely reaction video aI+hg

Here also a reduction without mercury, I find very interesting and reads easy, I will also try sometime.

 

[MadHatter]

I see no reason why gallium amalgamation shouldn't work. But to produce the al/ga amalgamation beforehand, I think you need a gallium salt. Otehrwaise maybe just try with a bit of gallium and alufoil in a rb flask, swirl it around until you can see them reacting. Then add P2NP and see if it reduces?

 

[MadHatter]

You could probably produce gallium chloride by dissolving gallium in concentrated HCl, then add that to aluminium foil. If you don't want to loose P2NP, you could always try to just add the amalgamated foil to water. If it produces bubbles, that's hydrogen gas from the reduction of H2O by the exposed aluminum.

mixxxmanI don’t know if you are aware but gallium forms amalgams with metals, including Al.Everything you said about Hg in the first paragraph can be applied to gallium.Please correct me if I’m wrong, anyone.
I read about liah, I don’t wanna work with it at the moment, too dangerous in my setting, And about Zn/Ni I dont know about at all, is there any info here? Thanks.

Great idea friend, we will definitely check it.

question: im following the rinse x 3 method, to eliminate as much mercury as possible, but iw we choose for example IPA as the solvent, the old rhodium/osmium synth , (in IPA or methanol) they dont rinse, and i suppose they belive all the mercury salts will be out of the mix when alkali/acid steps are done.... so... what you guys think about it?

the rinses when water is used could affect the final yield?
they say the yield is 90% of the mdp2p , which is a lot more of my yields...could be that the reason?

im doing microscale , but it shouldnt be the problem...

 

[IM BATMAN]

I do not close the flask at all, I just let the hydrogen escape and then simply do not smoke in time
Why do you want to close the flask?

Pennywiseive not closed in last synths, but after reading some interesting synth routes, some people put it at refluxoin to avoid methylamine loss... that sounds very logic, this could be the reason for lowering of final yields, less methylamine in the amalgam. im planning to use a single neck and put a condenser to reflux..... what you guys thinks about it?

as for my amalgamations, i just wait till bubbles+grey dots appears and rapidly discard water and rinse.... 3 times! .. my amalgam delayed more than 6 hours and final yield not as expected...well, i use thick AL foil in squares (my mistake) but was difficult to reach always 60º celsius and never got 100% AL "melted" , so i will try what Diogenes said, just discard the most water possible in 10 seconds and add the solvents and goods...then later in alkali acid purifications should go out the mercury..... im right?

the low temp, and delay on amalgam saying that im not doing all right..... im sure the rinses are the problem.

 

[G.Patton]

put it at refluxoin

IM BATMANWhat is it? Reflux condenser???

what you guys thinks about it?

It is need to use in amph synthesis (look at manual topic!)

the rinses when water is used could affect the final yield?

No, you should clean up your amalgam from acid (HNO3 is produced after Al+Hg(NO3)2 reaction).

Diogenes said, just discard the most water possible in 10 seconds and add the solvents and goods...then later in alkali acid purifications should go out the mercury..... im right?

Hg salt isn't dissolve in these solvents.

G.PattonHi Patton, I meant the Hg salt will remain in the discarded water phase, it`s solubility is very low in IPA. Rinsing is always recommended of course.

diogenes>it`s solubility is very low in IPA.
Hg salts immiscible with IPA. You can avoid rinsing. I got information that it has no influence on Hg in final product at all. One colleague made metal analysis for amphetamine and said that Hg there was 0.0003-0.0004 mg/kg.

G.PattonThank you Patton, you have finally confirmed my theroetical speculations here: http://bbzzzsvqcrqtki6umym6itiixfhn...hesis-from-p2np-via-al-hg-video.196/post-5921

This is real science and is extremely reassuring. My currilent post was only to add my experimeting that using a thicker foil, wasing only once and rinsing as quick as possible, it can still work perfectlty.

G.Pattonman, to be honest , you should have a bit more of patience, and maybe dont think the people are stupid just because are asking something thah you know easily....

anyway, you replied something very different in this thread about when start to add the ketone and methylamine after amalgam started, ive correctly asked about the best moment to add those, and as diogenes said for example, and you were agreed, the best moment is when the first 3 signs appears instead to wait too much...
thats what im asking for, i know how to do amphetamines.

i can understand those questions are boring for you, then i would recommend you to not reply to it.
i know deeply a lot of things in a lot of fields and if i really want to help, ill do kindly , because someone have the same doubt you had time ago.
dont take as an ofense, just saying.

as for the non english people trying to talk, be patient sir, there are much more people in the world talking spanish than english, and when a tourist or someone come to my country and at least try to talk spanish im always happy , kind and patient.
the other day i had to reformulate a question just because you think we all have to speak perfectly english..and every single person that readed it , for sure understood it.

 

[IM BATMAN]

as well , im clearly asked about the synth, methos can be found in rhodium etc... they dont rinse the amalgam, as well because they dont use water, they dilute in IPA or methanol... so... if there is any culprit, are them! haha

those guys knows what they are doing, i suppose they eliminate mercury in alkali/acid steps. you say that mercury doesnt dissolve on those solvents, but, they just dont get rid of mercury? never? thats my original question

 

[IM BATMAN]

I always look for industrial aluminum foils for thermal insulation, vapor barriers, sauna construction, roofing, etc. This is also usually 99.5% aluminum without coatings and is also much thicker (35-50µm) than the kitchen aluminum rolls. But there probably everyone has his own way of thinking.

PennywiseOH man.... why i readed this..... now im becoming crazy to found the appropriate one.... almost no one aluminum can be found with purity data.... found only one, but will delay 4 days or so haha... been reading about purity of comertial grade al foil ...and found some guys making a 6 samples study, and they found 5 of 6 have close to 99% ....do you think the commercial grade al is bad stuff? im using a 30 micrones thuckness foil used for put and smoke sishas etc.... not i dont know if im having a loss of yield due to poor quality..

 

[G.Patton]

man, to be honest , you should have a bit more of patience, and maybe dont think the people are stupid just because are asking something thah you know easily....

IM BATMANI'm extremely patient, man. Every day I answer to same questions. I'm a little bit confused when person don't try to write correctly question and than offend me that i'm not patient, lol. I can't read your minds... try to read what did you write before posting please.

IM BATMANYou are good person but here not a touristic place, here is chemical forum. I try to help you but I can't understand what do you want to say. It is a little bit harder than say of direction in a street.

IM BATMANMercury isn't bounded (connected) with amph free base. When you make extraction from amalgam solution, Mercury remain in water (which than be discarded).

G.Pattonthat bad english crossed the globe and never had problems...maybe i talk weird, but enough to understand, my english is auto learned, at least i try, but Sir, ill use the translator for you haha...kidding, i suppose you are bored to reply the same things day by day.
