Amfetamiininvideosynteesissä käytetään reagensseja:
  • 10 g 1-fenyyli-2-nitropropeenia (P2NP);
  • 100 ml isopropyylialkoholia (IPA);
  • 50 ml jääetikkaa (AcOH);
  • 50 g natriumhydroksidia (NaOH);
  • 12 g alumiinia (viipaloituna kotitalousfoliona);
  • 0,1 g elohopea(II)nitraattia (Hg(NO3)2);
  • 2 ml rikkihappoa (H2SO4);
  • 50 ml asetonia;
  • Tislattu vesi;
Laitteet ja lasitavarat:

Amfetamiinisynteesivideon kuvaus.
Ennen synteesin aloittamista valmistetaan 1-fenyyli-2-nitropropeeniliuos 10 g 100 ml:aan isopropyylialkoholia ja 50 ml:aan etikkahappoa. Myös alumiinifolio 12 g leikataan pieniksi paloiksi paperisilppurilla alumiiniamalgaamin valmistusta varten . Se voidaan leikata saksilla tai repiä käsin (käsineet kädessä).

0:04-0:40 - Valmistuksen vesipitoinen alkaliliuos. Tämä liuos valmistettiin etukäteen niin, että liuos on huoneenlämpöinen tämän videon pääreaktioseoksen alkalisointiaikaan mennessä. Alkalointi suoritetaan spontaanilla lämmityksellä. Jos käytetään tuoretta kuumaa aq-alkaliliuosta, lämpötila nousee korkeammaksi ja tarvitaan reaktiomassan pakkojäähdytys.

0:46-2:36 - Amalgaami elohopeanitraatilla. Amalgaami alumiinilla pelkistää
1-fenyyli-2-nitropropeeniaamfetamiiniksi. Amalgaamireaktion aikana kehittyy pieni määrä kaasua, ja muodostuu harmaa sakka. On tärkeää, ettei myöhästytä hetkeä, jolloin alumiiniamalgaami on valmis. Tämä hetki voidaan määrittää harmaan sakan muodostumisen ja lisääntyneen kaasun kehittymisen perusteella. Se tapahtuu 10-15 minuutin kuluttua reaktion alkamisesta.

Vesi valutetaan ilman harsoa, amalgaamioitu alumiini pestään kahdella annoksella kylmää tislattua vettä. On syytä kiinnittää huomiota kaasukuplien vapautumiseen. On huomattava, että kuplat ovat pienempiä ja nesteen väri on tummempi "oikeassa" amalgaamissa. Jos reaktio on raju, kuplat ovat suuria ja väri on vaalea, amalgaami on "väärä". Tämä johtuu lähes varmasti elohopeasuolan puutteesta. Huomaa, että elohopeasuolat ovat myrkyllisiä.

2:37-4:28 - Prosessin tärkein osa on 1-fenyyli-2-nitropropeenin pelkistäminen alumiiniamalgaamilla. Reaktio on eksoterminen ja se suoritetaan runsaasti lämpöä luovuttaen. Lämpötilaa on valvottava huolellisesti menettelyn aikana. Reaktiopulloa jäähdytetään jäähauteessa ylikuumenemisen varalta. Kolviin saa lisätä kylmää vettä. Joskus reaktio ei käynnisty, reaktiomassaa on lämmitettävä perusteellisesti ja reaktio aloitetaan (oikein valmistetulla amalgaamilla). Reaktion aikana vapautuu kiehuvan alkoholin ja etikkahapon hajuja.
Allihn-refluksilauhdutinta käytetään höyryjen talteenottoon. Allihn-refluksilauhduttimen tehokkuutta voidaan lisätä siihen liitettävällä juoksevalla kylmällä vedellä.

5:04 - Reaktiopullo voidaan huuhdella pienellä määrällä alkoholia ja myös reagoimaton alumiini voidaan huuhdella sillä jäämien keräämiseksi ja saannon lisäämiseksi.

5:13 - Reagoimatonta alumiinia pitäisi jäädä vähän. Reagoidun 1-fenyyli-2-nitropropeenin määrän voi määrittää jäämien perusteella.

5:16-6:13 - Alkalointi. Reaktio suoritetaan lämpöä luovuttamalla. Redusoimattoman alumiinin jäännökset reagoivat lisäksi alkalin kanssa ja lämmittävät seosta sekä muodostavat sivutuotteita.
Erottuminen näkyviin kerroksiin tapahtuu 30 minuutin kuluessa alkaloinnista.
Ylimmän kerroksen pH:n tulisi olla 11-12.

6:18-7:23 -
Dekantointi. Kerää pintakerros amfetamiinin emäksellä alkoholiin. Se voidaan kuivata pienellä määrällä vedetöntä magnesiumsulfaattia. Kuona voidaan uuttaa poolittomalla liuottimella (eetteri, bentseeni, tolueeni), minkä jälkeen liuotin haihdutetaan.

7:24-8:50 - Rikkihappoliuoksen valmistaminen asetoniin. Tätä liuosta tarvitaan tasaisempaa happamoitumista varten. Jos käytetään väkevää rikkihappoa, tuote happamoituu paikallisesti liikaa. Näin ollen saanto laskee.

8:51-10:53 - Tuotteen hapottaminen ja amfetamiinisulfaatin saaminen. Edellisessä vaiheessa kerättyyn ylempään keltaiseen kerrokseen lisätään tippa kerrallaan valmistettua rikkihappoliuosta. Jokaisen happoliuospisaran mukana muodostuu suolahiutaleita. Tämä vaihe on erittäin tärkeä, sillä pH:ta on säädettävä huolellisesti, jotta vältetään ylihapotus. Hapottamista jatketaan, kunnes
pH on 5,5-6. Ylihapotettu tuote on väriltään vaaleanpunainen. Tuote pilaantuu, jos se ylihapotetaan kokonaan.

10:55-11:38 - Amfetamiinisulfaatin
suodatus liuottimista Buchnerin suppilossa tyhjiössä. Tuote voidaan tässä vaiheessa lisäksi huuhdella kylmällä asetonilla kaatamalla se Buchner-suppilon läpi amfetamiinisulfaattikakun kanssa.

11:41-12:28 - Suodatus improvisoituja välineitä käyttäen. Suodattimena voidaan käyttää mitä tahansa paksua kangasta. Tuloksena syntynyt tuote kuivataan lämpimässä kuivassa paikassa useita tunteja liuotinjäämien poistamiseksi. On suositeltavaa säilyttää se tyhjiöpakkauksessa.

Saanto on 60-70 %

Hi Mister G Patton , after the Aluminum Amalgated with mercury ,
It is said we have to make : P2np + IPa + glacial acetic acid .


Can we replace the acetic acid with Citric Acid ?
In which quantity?

The usual replacement is formic acid, if it’s so easier. You can buy food vinegar the same way.

Yes, it's said above and every post about amalgam production. Same molar ration, you need to recount quantity in grams.

Would it make sense, when producing larger quantities of the product, to use solvents like DMSO (boiling point: 189°C) or toluene (110°C) instead of IPA (82°C), and to place pieces of broken porcelain in the reactor to stabilize the reaction?

The reaction is too violate and exothermic. It think, it have no sense.

DMSO at high temperature and the presence of acid will begin to degrade on DMS and release oxygen as an oxidizing agent. We have a strong release of hydrogen, which in the aggregate can give "explosive gas". Gently with experiments! In addition, DMSO itself is very smelly with high-temperature synthesis in the presence of many components. Try ethylacetate.

Please , ithe video shows 12grams of aluminum into a 2000ml flask .
But I wanted to go 24 grams of aluminum grit into the 2000 ml Flask
Please tell me what is ratio for all quantity of other components.

Is it 2 times more IPA ? Glacial acetic acid ? Sulfuric acid ? H2o ? Caustic soda ? And also what about the
Time for reaction ? Does time of reaction also double ? What about decantation when we double quantity for same glassware ?
( Attached the picture of 24 grams of aluminum into a 2 liter flask .)
Please respond need tour help to start

Hi, you need bigger flask. Multiply everything twice. Time is about the same.

Start with smaller amount at first.

Mister Patton , can I replace IPA by ethanol , to dissolve P2np for the main reaction into the synthesis '

How much is equivalent of Ethanol to replace 100 ml of IPA for this synthesis

Yes, you can. Same, I guess. You have to dissolve al P2NP.

You can use various solvents, we even synthesized in ethyl acetate (without acetic acid and alcohol). I think this drawback is solved in the process of hydrolysis when heated in the reaction mixture.

In 10L flask it is better not to synthesize more than 80g p2np. For 2L flask are similar - it is better not to synthesize more than 15g and in the presence of experience. With experience, you can better control the reaction, but the amount of the above will be a great risk.

What's the exact process of making the P2NP+IPA+GAA solution? Is it just mixing the appropriate quantity of each compound in a beaker, stirring it a bit and then letting it cool? I'm not sure why this part was skipped from the video.

When it has cooled by part of the P2NP can crystallize again. You can add this precipitate to the flask without dissolution or wash off an additional amount of IPA.

Hello!!

I am new to all this and would liek to give this a try and learn more

Do I need a fume hood for this?

I will have a respirator and nice gloves, is there anything else I need to watch out for?

Thank you

The main thing is to have time to cool the reaction while this does not get out of a flask with a volcanic effect. Evaporation that you can get the main IPA is not so critical.

depends on quantity of production,mostly just fumes, no open flames, dont ingest the poisonous chemicals.dont order chemicals from out of the country,they will get taken and maybe feds show up, dont talk to cops without a lawyer and dont let anyone in ur house unless they kick in the door with a warrant

You need to use a solution of acid (phosphoric or sulfuric) in IPA. This is shown and explained in detail in the video available on the forum.

Thank you for the previous responses.

The chemist has carried out their first (successful?) reaction and, as a result, has further questions.

The test subject, who evaluated the final product, compared it to the one commonly available on the street (according to police reports found online, its purity is usually around 10-20%).

I’d like to know whether the test subject had overly high expectations of the product, or if the inexperienced chemist might have made several mistakes during the process?

What can realistically be expected from the final product, and could further experiments significantly improve its quality?

The errors that, according to the chemist, may have affected the final product include:

• Completely skipping extraction with DCM (the chemist was prepared for it but lacked sufficient theoretical knowledge).

• Drying the product for too short a time and at too high a temperature.

Could this affect the product’s quality?

Does extraction with DCM involve adding DCM to the free base and collecting the appropriate layer? If so, are the layers clearly distinguishable, and which one (top/bottom) contains the product?

Could @G.Patton @William D. provide their input on this?
Thank you!

Hello.
It is quite subjective, has he checked its melting point? Isomer ratio also play role in the product activity. In addition, there is direct dependence between its purity and potency.

It's hard to estimate its quality in accordance with your description. You should check its purity in laboratory (such as EnergyControl or so) and then try to find a problem. Is your product absolutely white?

this step is quite important in order to increase the reaction yield and get rid of Hg salts in final product.

It also can influence on the product quality in case of air exposure during its strong heating.

Yes, he has to add DCM to the reaction mixture stir it well and then separate layers. DCM layer is clearly be determinated by its transparency and smell.

By the way, will you sell your product here?

Thank you!


No measurements were made, and the product was not 100% pure.


After adding the sodium hydroxide solution to the mixture, an oily layer separated after some time. So, should DCM be added to it after separation, or already at the stage of adding sodium hydroxide? I’m an amateur with a new hobby :) As you can see, I still have a lot to learn. I’ll follow the instructions and keep you updated on the progress. Any sale at this point is out of the question.

It has to be added after NaOH aq sln addition and 5-10min stirring in order to let it reacts.
