Synthesis of Amphetamine from P2NP via SnCl2 and Zn

[TucoSalamanca.]

How can I tell if it's amphetamines?

 

[GDC]

Drugtest, heat some of it to the desired temperature (it will melt and burn)

 

[GDC]

no, he use it for extraction but ether is compatible with the GAA?
I think problem is that the GAA is the solvent ...
And don*t forget the exothermic reaction with NaOH

 

[GDC]

oh sry you mean my point 5
You can use ether after zinc reaction

Thank you for your answer. This damn translator always makes us wrong. What kind of reagent is GAA? Glacial acetic acid?

 

[G.Patton]

Hello, it is said that there is an extraction procedure. EA here is used as extractant (solvent) for extraction of oxime.

 

[G.Patton]

Hello. How much grams of the target product have you got?

 

[hacke8]

Hello, thread creator, there are a few questions I would like to answer. 1 Is it necessary to evaporate ethyl acetate after using ethyl acetate extraction? 2 Is it okay to use 37% hydrochloric acid without water? 3 What is the PH value after adding sour water? 4 Can small particles of zinc be used without zinc powder?

Can 37% h2so4 Be used as acid?

 

[TucoSalamanca.]

From 7.5 grams of p2np I obtained 4 grams of amphetamine. Is it good?

 

[mithyl2]

have you tested it with a reagent?

 

[TucoSalamanca.]

I don't know what you mean.

 

[mithyl2]

A good way to test the validity/purity of a compound is to test it with a reagent chemical:

marquis is often one of the ways of testing amphetamine:
look up dancesafe for example, or 'reagent tests'

 

[mithyl2]

what was the concentration of the acid you used to precipitate the amphetamine at the end?

 

[TucoSalamanca.]

%98

 

[mithyl2]

How do you have such a precise measurement? Did you have it tested with gas chromatography?

 

[GDC]

he mean the sulfuric acid 98%

 

[mithyl2]

ok. i was asking about the purity of the amphetamine just before, so perhaps I should have touched on that. @tucosalamanca, have you definitely got pure amphetamine? mine is extremely contaminated as it has been with other methods

 

[TucoSalamanca.]

I have pure amphetamine, my first synthesis was dirty, my second synthesis was pure.

 

[mithyl2]

I don't have access to concentrated sulfuric acid where I am. If you have it could you try to precipitate the amphetamine with 85% phosphoric acid and see how pure your end product is?

I have no idea why the synthesis keeps failing for me, but I think the 85% phosphoric acid I'm using is the only thing that remains the same throughout all of my synthesis attempts.

Thank for any help

 

[TucoSalamanca.]

I tested the boiling point, true, but not the purity.

 

[GDC]

Thats ok. But the thread opener wrote: 90% of 15g are 13,5g

So you need: 6,75g

 

[TucoSalamanca.]

Holy shit.
