Temperatura in pH močno vplivata na izkoristek reakcije. Temperaturo morate nadzorovati, kot je opisano v priročniku. Prav tako morate kisanje izvajati zelo počasi, da bi ohranili izdelek. Prav tako lahko povzroči nastanek stranskih produktov.

oki, kakšen naj bo torej pH pred dodajanjem baze? glede na palice jih je 10 v 100 % in celo mislim, da jih je več: / tudi če se dvigne na 14, se bo kaj zgodilo?

pri temperaturi ne bo bolje, da bodo vse reakcije potekale v tistih 55-60? pri redukciji aluminijevega amalgama je temperatura takšna, zakaj nam tu dajejo višjo temperaturo?

Ali že imate izkušnje s to reakcijo?
Ali pa ste pri tej reakciji že imeli kakršen koli uspeh?
Kakšen je bil vaš izkoristek?

V redu je, plačati postopek zakisanja
ker je tu drugačna reakcija, ni amalgama

Vem, vendar sem mislil bolj na p2np, ki ima tališče 63-65 stopinj ... zato je moje vprašanje, ali ne bo reakcija pri 55 stopinjah ves čas reakcije boljša rešitev ...

no ... kako vedeti, da je vse reagiralo in da je reakcija končana? Predlagam, da bakrov klorid potone na dno... je to dober izhod?

Uporabite lahko Tankoplastna kromatografija (TLC) zdravil. Naredite dve madeži: enega z reagentom in enega z zdravilom. Nato izvedite TLC in preverite količino p2np v zmesi izdelkov. Če v mešanici izdelkov ni p2np, če je madež zelo majhen, je reakcija končana.

Če prav razumem, kako se P2NP reducira v amfetamin, NaBH4 reducira skupino -NO2 in alkensko skupino. Ne razumem pa, kakšna je vloga CuCl2. Prosim, razložite, kako deluje ta mehanizem. Vnaprej se vam zahvaljujem.

Pozdravljeni. CuCl2 v tej reakciji deluje kot katalizator. Ali potrebujete podrobnejšo razlago?

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.

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.

Pozdravljeni, zanima me, ali se lahko redukcije izvedejo samo na vodi? po alkalizaciji vlijte nepolarno topilo in izvlecite prosto bazo. je to mogoče ?

klikni. Koraki 1-5 so boljši v pogojih brez vode (z enim ekvivalentom NaBH4). Nato so z nastalim nitropropanom in kovinskim kloridom kot katalizatorjem možni vodni pogoji.

@William Dampier kakšen je BP amfetaminske proste baze in ali jo je treba destilirati v vakuumu?
Ali je primerna tudi destilacija s paro?
Hočem samo, da je moja Freebase brezbarvna kot voda!

Koliko največ litrov reakcijske mase bi lahko naložili v stekleni reaktor s prostornino 100 litrov?

ali je to pravilna številka cas za P2NP: 705-60-2

ali bodo ustrezale tudi druge številke cas?

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

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

To je pravilna številka CAS, zato vam priporočam, da se držite te številke.

S foruma se lahko obrnete na Constantylious777, ki prodaja kakovostno P2NP, obstajajo tudi drugi prodajalci clearnetov, ki ponujajo ta izdelek.

Pozdravljeni, imam nekaj vprašanj o sintezi.

6. Reakcijski zmesi smo dodali 25-odstotno vodno raztopino NaOH (8 litrov) in ločili fazi.

V: V sintezo dodate NaOH in sinteza se razdeli na dve plasti, spodnjo plast odcedite, zgornjo pa obdržite?

7. Vodna faza je bila nato ekstrahirana z 8 litri IPA.

V: Tega dela ne razumem, po ločitvi iz koraka 6 dodate 8 l IPA in ga zmešate?

8. IPA je bil izparjen v vakuumu do olja.

V: Ali lahko za izparevanje IPA uporabim domač majhen destilator? In pri kakšni temperaturi ga je treba izpariti?

9. Olje je bilo raztopljeno v dveh litrih acetona.

V: Tega dela ne razumem, aceton dodamo olju in nato začnemo s postopkom z žveplovo kislino, da dosežemo pravi pH?

Bdst regards

Pozdravljeni, iščem odgovore na ta vprašanja. če ste jih dobili, ali jih lahko vidim? Pregledal bom nit in videl, ali jo lahko najdem.

Ali natrijev borohidrid ni drag?
In pri 3 kilogramih za proizvodnjo 1 litra amfetaminskega olja bi bil strošek nekoliko previsok, da bi bil privlačen.

Ali ste po tej poti končno sintetizirali amfetaminov sulfat (speed)?
