Syntéza amfetamínu z jedného hrnca z P2NP pomocou NaBH4/CuCl2 (v mierke 1 kg)
- Thread starter GhostChemist
- Start date
Na 100 % som si istý, že v gramoch ďalšej dávky urobím obrázky. Z 287 gramov P2NP som získal 254 gramov freebase.
Pri pridaní kyseliny fosforečnej na moju 67g dávku p2np som nedostal veľa soľnej zrazeniny.
zmení sa to počas zmrazovania? myslel som si, že som celkom dobre dodržal pokyny.
po skončení pridávania p2np sa prejde hneď na cucl? alebo mám počkať, kým prestane reagovať?
po pridaní lúhu som to pretrepal a nechal som to asi hodinu a pri extrakcii s ipa som to nechal oddeliť a potom som to znova 3/4 krát premiešal.
Vákuovo som destiloval z ipa pri 50-60oC , bolo to príliš horúce?
možno som to okyslil príliš rýchlo, keďže môj sep funeel mal ešte vodnú vrstvu ( pre istotu robím 2 extrakcie ipa), tak som použil striekačku a nebolo to presne po kvapkách.
Nejaké nápady? Budem to aktualizovať po tom, čo bude cez noc v mrazničke.

Habe es auch versaut beim ersten mal gucke grad nach lösungen und schließe mögliche fehler aus. Hat sich bei dir auch nur ein kleiner teil umgewandelt und es ist größtenteils flüssig geblieben?

Was your freebase purified? This reaction produces quite alot by-products so it's absolutely required to steam distill the freebase. Put 1ml freebase oil on petri dish and let evaporate. If the residue is not white it's not pure. If it's not pure and you turn it to salt, your power doesn't dissolve in water easily and yoy'll get sick if you take it.
So this was the boiling temp in the flask or bath temp? Not sure if too hot when I did it the BP was ~38 C while the water bath was kept < 60 C. (The BP only depends on pressure so higher bath temp. only makes it boil more violenly at same temp.) Do normal distillation of your vacuum distillate and see if anything solid remains in boil flask.
Might be dissolved in the water in it.

Good to know the destillation is essential for this process thanks. I kept the oil and will try to purify it with destillation and see what comes out.
Od pattona som tu počul, že by ste ju mali predtým zahriať. niečo, čo som so sírovou nikdy nerobil, ale na druhej strane je moja kyselina dosť čistá.
Ak ste v EÚ, objednajte si ju z Poľska, predajú vám sudy doslova s čímkoľvek lol

Darfst du mir hier verraten woher du die schwefelsäure beziehst oder muss ich dir privat schreiben? Habe grad probleme welche zu beschaffen nur phosphorsäure iaz für mich aktuell laufend zugänglich.
It would be really REALLY great if someone could run a TLC analysis of the products from this reaction. I've read that NaBH4/Cu reduction mainly produces N-hydroxylamines instead of amines for alpha-alkyl nitrostyrenes. Because of similar melting points for their salts and similar boiling points, the only way to separate and identify N-OH-amphetamine is by chromatography. The N-OH product is also active as a stimulant but it is different to amphetamine. I wonder if this is really true.

what source reports this information?
all compounds tested with qualitative and quantitative analysis
N-OH group can be formed as an intermediate compound if the experiment is not carried out correctly

Yes, I should have probably researched this a little more before posting here, apologies. The source for this comes from amateur chemists and there aren't any official publications to support this
