10 ml asetonu 1 ml konsantre %97+ sülfürik asit üzerine 10:1 oranında dökün. Pipet veya şırınga kullanarak pH 5,5'e ulaşılana kadar çözeltiyi yavaşça damlatın. Aşırı asitlenmişse daha fazla freebase ekleyin, aşırı asitlenmiş ve sıvıya dönüşmüşse a/b'ye ekleyin ve yeniden kristalleştirin.

Ben de touleni düşündüm ama yoğunluk farkının çok düşük olduğunu düşünüyorum, değil mi?

Merhaba, raporunuz için teşekkür ederim! Gerçekten ilginç. 10 g amf içermeyen baz %80,4 verim, oldukça iyi. Ne kadar tuz elde ettiniz?

i just did this synthesis successfully ! (i was very astonished, that it works, like described...!)

i used 1,7g P2NP

- created sncl2 sol. from h202 and conc HCL first, until total dissolution, quenched oxidizing agent w. Bisulfite.

- dissolved p2np in acetone / EtoH and brought solutions of sncl2/p2np-solvent together in 250ml RBF

vigourously stirred for 2hrs.

------SKIPPED OXIME ISOLATION !!!!! -----

instead gave antoher dash of conc. HCL in to the whole

and gave finely divided active-C powder a hydrogen absorber in to RM.

then three portions of Zn-dust were introduced in several heaps...with subsequent hcl/EtoH addition.

as the reagents were used up i gave a small am. of AcOH to the whole and let it further react out a 15mins.


- now i slowly alkalized to ph 12 (metal precipitates formed immediate and sank...no hassle in base extraction....did with xylene/pet.ether/naphta mixture (+a small emulsion preventing splash of 2-propanol , every extraction step...)


i pooled organic xtracts, washed them with conc.brine f. rocksalt....)

afterwards the washed org.phases were run trough fine filtering apparatus.

added a 100mls of H20 and then titrated with Hcl until ph 5,5 ~


the acidic solution was equiv. mixed with acetone / ethanol-2propanol

with concentration under stirring with surface vent.

then the pasty residue was further refined...

I OBTAINED almost 1,3g amph-hcl (hygroscopic but useable!)

so that is a fine well thought route to go, THANKS TO ORIGINAL MASTERMIND

* MAJOR ! update:...

I DID ONE MORE "GOD-MOVE" AFTER THIS SURPRISE RESULT:.....


I SUCCEEDED IN MODIFYING THE SYNTHESIS - AND DID A REDUCTIVE AMINATION

WITH REFINED P2P AND METHYLAMMONIUMACETATE (OR KIND OF)

IT YIELDED METHAMPHETAMINE RACEMATE.... VERY UNEXPECTED QUANTITY- QUALITY AS SAME AS THE USUAL NABH4 ROUTE I PREFERRED BEFORE...



IT WENT DOWN FROM Imine formation -[ACIDIFIED VARIANT]...... TO HYDROCHLORIDE OF SLIGHT PINK APPEARANCE OVER NIGHT !

-->AT ROOM TEMPERATURE<----

PLEASE dont be mad at me but i decided to keep specifics for myself**

it is a whole new approach to phenetylamine syntheses in general ....

CREDITS TO THIS COMMUNITY PRO INSTRUCTIONAL P2P PURIFICATION TUTORIALS / I WENT TROUGH THE HASSLE OF THE WHOLE WORKUP TECHNIQUES OF THE BB-gate wisdom ...

THE PHENYLACETONE I DERIVED BY : Fe/H+ --P2NP---> Phenyl-2-Propanone



**(exception 4 you, Patton ..i made a writeup , documenting specs etc. i think you get what these
synthesis-dynamic principles hold in value )

Bunun işe yarayacağını sanmıyorum. Umarım işe yarar ve denemek zorunda kalırım.

Borohidrit yöntemini birçok kez denedim ama başarılı olamadım. en son %0,2 oranında amfetamin elde edebildim. yine de gerçekti. bunun işe yaramasına çok ihtiyacım var ve bu beni delirtiyor. dcm'nin nasıl gittiğini bize bildirin.

Ekstrakt için DCM'den başka bir yol var mı?
Belki n-Hekzan?

Merhaba arkadaşlar, bu reaksiyon sadece feniletilamin (PEA) üretmiyor mu yoksa ben sadece aptal mıyım (güçlü olasılık)

Part of this method allows you to get phenylacetone. But stage 2 can be difficult.

Merhaba arkadaşım
Yorumunuzu okudum ve çok beğendim
Saf amfetamini nasıl elde ettiniz (ikinci adımda)?
Lütfen hangi amfetamin üretme yönteminin daha iyi olduğunu ve sonuçta daha yüksek saflık yüzdesine sahip olduğunu önerin
Ve hammaddeleri mağaza aracılığıyla temin ettiğini
(Profesyonel bir laboratuvarım yok)

Zonder de kosten van 300 gram P2NP .
alle grondstoffen voor 200 gram amfetamine free base kosten hier €416,68???
Mooi recept alleen het kan totaal niet uit
