Ühe poti amfetamiini süntees P2NP-st NaBH4/CuCl2-ga (1kg skaala)

[Montecristo]

Siin oli see, mida ma väiksemas mahus tegin;
1. Lahus IPA/H2O 2:1 ((IPA 800ml,H2O 400ml)(1200ml)) lisati 2000ml kolbi.
2. Lisati kohe NaBH4 (116 g) ja alustati segamist.
3. P2NP (67 g) lisati väikestes annustes, nii et segu temperatuur ei ületaks 60 *С.
4. CuCl2 (7 g) vees (13 ml) lisati aeglaselt tilguti, nii et segu temperatuur ei ületaks 80 *С.
5. Seejärel reostati reaktsiooni 80 °C juures 30 minutit välisküttega.
6. Lahus dekanteeriti ja filtreeriti reaktsioonijäätmetest ning pandi eraldussahtrisse.
7. Reaktsioonisegule lisati NaOH 25%-line vesilahus (533 ml) ja faasid eraldati.
8. Alumine kiht kurnatakse suurde keeduklaasi ja kogutakse ülemine orgaaniline kiht.
9. Seejärel pandi vesifaas eraldussahtrisse ja ekstraheeriti 500 ml IPAga.
10. IPA aurustati 3/4 ulatuses, pooleldi piimjas vababaas ja pooleldi IPA.
11.IPA ja freebase lahustati 130 ml atsetoonis.
12.ortofosforhapet tilguti pH-ni - 6 (pideva segamise juures).
13.segu pandi 12 tunniks sügavkülma.
14.Pärast kristalliseerumist suspensioon filtreeriti ja pesti kuiva külma atsetooniga, kuni atsetoon on puhas.
15.Pesemisest saadud atsetoon ja ipa/atsetooni segu pannakse tagasi sügavkülma edasiseks sadestamiseks.
16.Protsessi korratakse, kuni ei teki enam sadet, et saada 60-70% kvaliteetset amfetamiini, kuna segusse satub rohkem atsetooni, võib olla vaja tilgutada veel veidi hapet, et seda vähendada, kuid mitte liiga palju, kuna atsetoon on ph7.

Siin on foto mõnest kuivatatud pastakivist , ülejäänud on kuiv pulber, mida tuleb segada, kuna see on minu ja mu sõprade jaoks liiga tugev.
Ma võin retsepti uuendada ja teha kirjutama väikesemahulise kodukeemia jaoks, seal on palju võimalusi, kuidas see võiks olla parem.

 

[flyhigh]

see ei ole met , saate siit kirjutada, kuidas teha seda kristallmetalliks

 

[Kylemalone1297]

A different process. P2P or sudo. Just pick one. But these are safer imo

 

[G.Patton]

Tere. CuCl2 Toimib selles reaktsioonis katalüsaatorina. Kas vajate üksikasjalikumat selgitust?

 

[Kylemalone1297]

I would like to know the entire concept if u k know it. Like how much copper to reduce p2np exactly. Are we making an electron here in this synth? What is going on exactly ? I understand how to run through but not the actual chemical reaction that is happening.

 

[G.Patton]

What do you mean?
There is clearly said how much. 105g CuCl2 per 1kg P2NP.

NaBH4 donate hydrogen while this reaction to P2NP and nitrogen atom change its oxidation state from +3 to -3. Hence, it get 6 electrons.

ja millist % väävelhapet tuleks kasutada?

 

[Kylemalone1297]

Buy virgin sulfuric from as drain cleaner if u can’t find one with a high purity. I could only find like 20% online for some reason. The drain cleaner is actualy more pure. Like wtf

 

[G.Patton]

it's worth to use 96-98%, but you can use less concentrated as well.

 

[WinterDust]

Tere,

Küsimus,

Kui amfetamiiniõli kristalliseerub väävelhappega, on aeg amfetamiini välja filtreerida Buchneri trummeliga, minu küsimus on järgmine. Millist filtreerimispaberit soovitatakse selleks kasutada?

Näiteks vaatan filtrit, millel on järgmised omadused, kas see on hea soovitus?

Filtri omadused:
Paberist valmistatud filterpaberid
Kõvad filtrid - filtreerimisaeg 140 sekundit (retentsioon> 2 µm). Aeglane filtreerimine.
Tihedad filtrid peente ja väga peente setete jaoks.
Kaal: 85 g/m2.
Paksus: 0,17 mm.
Filtreerimisaeg: 140 s.
Retentsioon:> 2 µm.

Lugupidamisega

1. Material:
Generally, tissue paper is not recommended for chemical filtration, especially in organic chemistry, as it may not provide the necessary chemical resistance and could introduce impurities.

3. Retention:
This retention level is suitable for filtering out larger particles, but if the amphetamine salt crystals are smaller than this size, they may pass through the filter. For crystallization processes, you typically want a filter paper that can retain smaller particles, ideally in the range of 1 µm or less.


4. Weight (85 g/m²) and Thickness (0.17 mm):
a relatively dense filter paper, which may be good for fine filtration but could also slow down the process. Thicker filter papers tend to have lower flow rates

Recommendations​

Quantitative Filter Paper:
Look for papers with a retention size of 1 µm or less, which would be more suitable for filtering fine crystals.


Buchner Funnel Filtration:
Whatman filter paper or similar brands that are specifically designed for vacuum filtration. These papers are available in various grades, including those with finer retention capabilities (e.g., Whatman Grade 1 or Grade 2).

Let me know if something is wrong

 

[ASheSChem]

hea küsimus... ka mind huvitab...
Tegelikult kasutan ma seda

aga ma ei tea, mis see on lol

ma nägin palju tüüpi filter "kvalitatiivne" või "kvantitatiivne" ja igas kategoorias versioon "aeglane" "keskmine" ja "kiire"...
mis on parim ?

Quantitative Filter Paper
Specification: 9.0 cm
The second image has a table with various specifications, likely describing different types of filter paper based on attributes like thickness, pore size, or filtration speed.

What is a purity of a final 60% - 70% yield? I found that there is such thing as amphetamine paste and amphetamine sulfate and sulfate is x2 in price. What is this final product (124.4g on video)?

 

[aaduo04]

a videóban a végső mennyiség szulfát. A paszta konzisztenciája tömeg szerint 3x lehet, mert az oldószerek nem párologtak el. (javítsatok ki, ha tévedek).

 

[G.Patton]

About 95%.

 

[Kylemalone1297]

Can I do a run of the synth with only 5g p2np ? To get a grip on it first.

 

[G.Patton]

You have to! Small scale batch is necessary to carry out several times before large one in order to understand this synthesis and remember it well.

 

[Kylemalone1297]

Is 5g p2np okay or too small ? And is pressure required during reaction or just the constant heating ?

 

[G.Patton]

Yes, okay. Atmosphere pressure.

 

[Kylemalone1297]

Is the pressure required or will it do fine just running hot with no pressure? Do I need to hold as much pressure as possible ? I have a nice 1000ml heavy wall round bottom. So it will hold some, but if it isn’t needed I won’t worry about it.
