Hočete reči, da je porpocija 1L pirolidina za 1kg
2-bromovalerofenona, koliko etil acetata pa potrebujem za izdelavo alfa-PVP?

Imam težave z izkristaliziranjem. Katere so običajne rešitve za to, zakaj imam težave s pridobivanjem kristalov?

Mislim, da morate tekočino zamrzniti za 2 dni, potem lahko vidite, da se oblikujejo nekateri kristali, enako kot pri sintezi kristalov hmtd, nisem prepričan, da bi lahko pomagalo
⏳⌚ je bolj pomembno pri kristalizaciji v zamrzovalniku

Uporabite lahko ekvimolarno razmerje in preverite pH raztopine.

Tu se le sprašujem in nisem kemik, vendar domnevam, da začnete z 2-bromo-3,4-metilendioksi benzenom, reagirate z velarilkloridom in dobite 3,4-MD-valerafenon

Mislim, da potrebujete valerofenon za alfa-PVP in heksanofenon za alfa-PHP.
Ali kdo pozna ime osnovne kemikalije za Alpha-PiHP?

Seveda je še bolj zanimiva naslednja kemikalija v procesu:
2-bromo-4-metilpentanofenon
Ali kdo pozna ponudnika za to kemikalijo?

Po dodajanju vode v fazi halogeniranja imam to...
Moja vprašanja:

1. Kaj delam narobe?
2. Ali ga je treba spustiti ali lahko "prihranim" drag valfen (#1009...)?

hvala!

p.s. mešam v rokah, ker moje magnetno mešalo ne more pravilno mešati (majhna količina tekočin)
ampak,,,, barve, beljenje in druge stvari so enake kot v videu....

Zakaj ne uporabljate neposredno 2-bromovalerofenona?
Zdi se, da ga je lažje dobiti kot pirolidin.

Pozdravljeni, imam majhno težavo, za 25k 2bromovalero sem uporabil za kristalizacijo po pirolidinu in po pranju, uporabil sem za kristalizacijo 1,5l acetona in 0,38 kisline na 1kg broma, vendar tekočino za kristalizacijo vzamem 1l in naredim ph 2 z mešanico acetona in kisline, po 10h v zamrzovalniku se ni zgodilo nič (mešal sem 4 ure s pirolidinom pri temperaturi 55), kaj sem naredil narobe in kako to popraviti?

Pozdravljeni, če ne želim opraviti destilacije, ali je to težava ? ali se destilacija etil acetata uporablja samo za obnovo topila ? ali bo to povzročilo težave pri topnosti soli a-pvp ?

Ali lahko namesto etilacetata uporabite drugo topilo? Morda IPA ali ksilen? Ali to spremeni rezultate?

fotografija #1 2-bromovalerofenon z etilacetatom (moj 2-b-vp je po halogeniranju kristaliziral, morda je to težava? ampak kaj delam narobe? morda je HBr preveč koncentriran? vendar se je po dodatku EtAc raztopil)
...
Fotografija #2 se je razbarvala in pokvarila po 4-5 kapljicah pirolidinena, dodanih v Rm s fotografije #1

Veliko hvala!
