Amphetamine synthesis from P2NP via Al/Hg (video)

[Xiaoyan]

Hello,
I have a question about laboratory equipment,

Apart from borosilicate glass, what other types of materials can be used as reactor?
Would it affect the quality of the synthesis?

What equipment is recommended to synthesize 500 P2NP g.??

Thank you

PP. HDPE or even metal if you apply a protective PTFE coating to the whole interior surface.
Barrel in barrel, so you can cool and heat. Large condenser made from pipe in pipe.Hole for condenser, hole for teflon overhead stirring adapter (Or a large cement mixing drill hooked up to a regulator).Your aluminium needs to be thicker than sub 50-100g reactions, much thicker or else it will go out the condenser.The limit is 100g is said, but I am fairly convinced you can scale up a lot more.There is 1 person here that I know of that does 1kg reactions with this method and by what he says it takes "hours" to amalgamate and aluminium sheet is used.

 

[UWe9o12jkied91d]

No, it should not affect quality, but watch out, at room temp. both hdpe and pp are fine in almost anything but at 110*C they start deforming especially under solvents, acids etc.

 

[Xiaoyan]

Ok.
The ideal temperature range for a good synthesis is between 50 and 70°C aprx, right?

 

[UWe9o12jkied91d]

Yes, but at the first addition the temp. may suddenly rise higher than that

 

[Xiaoyan]

Any recommendations on the thickness of the aluminum that I should use and how to make the amalgam with that
aluminum?
Should I cut it to some size?

 

[UWe9o12jkied91d]

I worked well with 0.25mm-3mm "sheet" ,I say in quotes because its bendable by hand easily. I cut into small sizes and do 1-2 sec blitz in coffee grinde/blender just for a bit of surface area

 

[Xiaoyan]

3mm aluminum, for what amount of p2np is it recommended?
Does it grind well with a coffee grinder?

 

[UWe9o12jkied91d]

0.25-0.3 , pardon me

 

[Xiaoyan]

Oook
I am ussing 0.04 mm Al to synthetize 50 P2NP
Can i use the same Al to synthetize 100?? 200?? 300???

And another question, if you don't mind,
What kind of Teflon spray can be used to cover a drum??

I'm looking and I can only find spray for lubrication....

Please start from small amount. when You see problem with cooling think how solve it. You can have easy 1/2 of stuff on floor - (better option). Worst on You. mean all you place is dirty with mercury ;( my opinion painting the barrel is a dead end.

Here you go, right in your backyard, this is 1 example, they have many more, check specifications, temperature, substrate, room temp or heat cure etc

How do I know whether my respirator protects against mercury vapours or not? (I am synthesising Mercury(II) nitrate myself via mercury and nitric acid so some mercury vapour will be produced).
Does it matter whether I use glacial acetic acid or just acetic acid? I'm finding it hard to find a supplier for glacial acetic acid.

 

[UWe9o12jkied91d]

Maybe a test strip for toxic stuff? They sell it at lab stores. Wet down the used filter and blot the strip I supose.
But I think you are over-worrying.Mercury has a very high boiling point 360 ish degrees C, your condenser will take care of it and even IF some mercury vapors get carried by other gasses outside the condenser it so minute in quantity you're probably ingesting more eating salmon.
You can even use just water, so naturally 80% or whatever you can find is ok.

 

[purple_rain]

Ah okay, thanks for the advice.

Why it play mdma music when making amphetamine. can not delete

 

[purple_rain]

Instead of using an item of clothing to filter the amphetamine sulfate, can i use filter paper? Also, Since I will make a solution of elemental mercury and nitric acid, how should I store it as I won't need the entire solution for one batch of amphetamine?

 

[UWe9o12jkied91d]

You can use coffee filters from the grocery store, better than paper.
Depends on the conc. of the acid, up to 70% it should be ok in hdpe

 

[purple_rain]

Thanks

Since my very first succesful synthesis few months ago, I've tried many various combinations of synth. optimization, mainly related to easier/cheaper purification. So I've got for you some kitchen tips and tricks:

1. For the first acidification of decanted Rm use gaseous HCl instead of liquid solutions. Why? if you are going to make AB extraction anyway, then intermediate ion doesn't really matter, but also it's almost impossible to accidentally overacidify Rm, due to freebase's solution anhydrous environment, excessive HCl just go straight to fume vent. I've noticed that this process appeared noticeably more, time- and cost-effective if you bubble trough diffusor, not just straight rubber hose (imho best and easiest to obtain is firmly porous aerator stone for aquarium, but it can't be made of natural basalt or other HCl-vulnerable rocks) and use narrow, tall beaker.
2. This tip could be very useful for ppl working with relatively huge volumes of freebase at one time. It's really not that complicated as it might be written. If the first salt precepitation appeared to be so easy and stress free, but you can make the next acidification to be nearly the same as previous. I bet you are equipped with some precise scale and some sort of drying chamber (bake oven), so you can sample around few ca. 200mg samples of filtered salt, and just simply conduct gravimetric designation of moisture content, this ISO standard procedure can be read in some all-is-free internet libraries. How much is 'few', it's up to your judgement. After last dry-weighting these samples can go back to their batch. Why would you even had to be keen on doing some ordinarily optional process? Well, firstly you'd be able to decently precise calculate your raw Rm yield by applying dry mass content for rest of still wet batch. So it's that everything useful? No, not really. You can do some fabulously easy stoichiometric equations and very precisely calculate total amount of solution to get pH.6. Simply check calc. twice and calmly dump 80-90% of total acid. The rest is added dropwise as it always was.
3. If you'd had a chance to catch an opportunity to buy a "short expiration date" bottle of HPLC grade isooctane for a small fracture of it's price; You'd better read it carefully: it's not mouldy, just stability and purity certification won't be guaranteed. But it doesn't bother us anyway. I always conduct the last AB precipitation with base extract in isooct, solution, and acetone/food grade phosphoric (V) acid. Why it's so wonderful? No heavy metals content like fairly frequent had eg. petroleum ether, also polarity index 0.1 what makes this solvent 2nd most insoluble liquid in water, and whole bunch of properties. But it can separate totally in funnel under 5 minutes while freezing cold, and somehow magically acts like most precise pH quench indicator in the world. In quick, you got casually milk, porridge, and very often using pH papers,. but in isooctane/acetone solution stirred in magstir max rpm, always "The last drop" makes the foggy solution bind together in characteristic powdery clouds, making the top of solution totally clear in seconds also giving ideal pH at the time . (do we have any PhD of chemistry to try explain it for whole community?) Also if ABExtraction was done properly, you can repeatedly reuse it as the best of available reaction buffer.
Feel free to ask about these.

Do you produce amphetamine*HCl for personal use?

 

[Heartburn]

It's just an intermediate form among all of purification steps. Final ion is usually sulphate by choice. Because none of known titration indicator is applicable for this specific case, You must use tons of indicative papers to catch endpoint of unknown concentration solution, I can't just cheap and quickly get valuable quality sight on the most important step. As is commonly suspected, gasing out freebase by bubbling some seriously nasty toxic gas made in modern adaptation of antique Kipp aparatus, when critically essential, is probably the most danger and the least cost effective way of salting. But it is simply impossible to overacidify anhydrous freebase solution, especially when actual yield is a lottery. Excessive HCl just bubble out to happily catch moisture from air and chew any metal surface over time. By getting more familiar with al/hg reduction, I've decided to enact A-B extraction in my slightly updated version of this recipe. Since then I make full A-B as mandatory synthesis step, even if first freebase layer looks almost colourless. It's just for my own health. I've made roughly 15-20 batches, always 10-20grams, and it comes out different almost every time. Not just appearance differs but also how it will effect your behaviour when boozed.
For me; as longtime analytic laboratory worker, my average reproducibility factor is serious reason to be self ashamed. Literallly everytime it gets different, no matter if they're made from sub's taken from the same as yesterday, including deionised water. Now by the "describe every detail' method, i'm trying to catch a pattern of which process detail can affect final product when neglected. Sometimes effort on making Mr. Hyde as professional as like Dr. Jekyll is so uneven to make seriously doubt in myself as professional. In particular, when it comes to comparison of my final result vs expected target as it was presented in this topic video. @G.Patton you can DM me to share some knowledge with each other.
