Reakcijska shema:
Az2tuxXNyp

Sinteza:
1. V reaktor, opremljen z mešalnikom, termometrom, povratnim hladilnikom in lijakom za kapljanje, dodamo 600 g POCl3.
2. V lij za kapljanje nalijemo 1000 g 1-naftojske kisline in 500 ml dimetilformamida.
3. Reakcijsko maso segrejemo na 100 *С. V 30 minutah je bila zmes dodana iz kapalnega lijaka.
4. Nato smo povratni hladilnik zamenjali z ravnim kondenzatorjem in destilirali nastajajoči propionilklorid.
5. Nastali klorid 1-naftojske kisline se destilira pri tlaku 35 mm in temperaturi 190 *С. Dobljenih je bilo 1170 g kloranhidrida 1-naftojske kisline (izkoristek 93 %).

Ali obstaja boljši način za sintezo 1-naftoil klorida

Ali lahko namesto naftoilklorida uporabim benzoilklorid 99 %?

1-naftoilklorid se topi pri temperaturi 16-19 *C.

Če v naftoično kislino dodamo HCl, ne bo nastal naftoilklorid?

Rdeče obarvani izdelek in odpadki se strdijo. Izdelek je pravilen ali pa gre za nekaj drugega.

Vendar je izplen zelo majhen. S 100 g naftoinske kisline je nastalo le 18 g produkta.
Pravzaprav je šlo za dve stvari.
(1) dodali smo 30 g dodatnega DMF, da bi pravilno raztopili naftoično kislino.
(2) zaradi nepričakovanega razloga je reakcijska masa ostala čez noč.

Kadar se izvajajo pravilno. Rezultat je videti takole. Vendar je izkoristek še vedno zelo manjši od pričakovanega ~45 g. Ali lahko razložite razlog za to?

Pozdravljeni, ne morem odgovoriti o izdelku po sliki. Preveriti morate temperaturo taljenja.

Pozdravljeni, kako ste? Ali se lahko pozanimam o alternativi naftoil kloridu? Koliko snovi lahko zapišete?

Uporabite lahko številne druge reagente, vendar kot končni izdelek ni JWH-018. Nastale bodo druge serije kanabinoidov.

Ali nam lahko poveste, kateri so alternativni reagenti za naftoilklorid, ker ga težko proizvajamo in pridobivamo?

@G.Patton povejte mi tudi, kako odstraniti trdne odpadke, ki nastanejo v reaktorju?
Ali alkoholni NaOH očisti reaktor?
