Stavo cucinando il CBD e per errore ho aggiunto NAoh alla miscela, credo che l'isomerizzazione si sia fermata. Si sono formati 2 strati, qualcuno può dirmi cosa si è formato? È un buon modo per estrarre l'estratto di THC?

Sto usando metanolo e HCL

Salve, a che punto è l'aggiunta di NaOH?

La risposta può essere data dall'analisi HPLC.

Dopo 2 ore di isomerizzazione si è formato un olio, ma ha un odore sgradevole e non so come purificarlo.

Quando ho aggiunto Naoh, le due fasi si sono separate e credo che la reazione si sia fermata. Ho provato a lavarlo in molti modi, ma non riesco a liberarmi di questo cattivo odore.

le basi convertono il cbd (il thc non viene convertito) in alcuni derivati chinonici. credo che si possano usare diversi solventi per separarlo dal thc, ma non ricordo quali, e in quale letteratura è stato descritto, anche perché è verde (presumo), anche alcuni impuriti vegetali possono essere ossidati.

Cos'è meglio l'acido acetico o l'acido cloridrico? Ho un olio lasciato con un odore disgustoso che faccio per pulirlo o estrarre il cbd puro loas da metanolo

Il toluene a temperatura ambiente e l'acido p-toluensolfonico possono essere utilizzati per ottenere un delta 9 quasi puro, mentre altri solventi con il calore producono un delta 8.

il toluene può essere difficile da rimuovere, ma, 44 ore (48 ore daranno luogo a una conversione leggermente maggiore, ma di circa il 10% delta8), agitare il 10% di ptsa e una quantità di toluene sufficiente a dissolverlo, quindi procedere alla lavorazione

Quando si aggiunge acqua satura di NAOH per contrastare l'acido, non riesco a eliminarlo tutto e se aggiungo troppa acqua la fase superiore diventa nera. Come posso fare l'estrazione? Come posso eliminare l'odore di acido? Ho provato a pulirlo con acqua distillata ma non ha funzionato.

Ho bisogno di aiuto per favore

A che PH devo lasciare il THC? Posso usare butano o toluene per purificare il THC?

I metodi che utilizzano acidi in quantità catalitiche si sono affermati meglio che in questo argomento. Con pTSA 10% mol in DCM (delta-8) o con HCl 0,05% in etanolo (delta-9)

si può usare un alcool diverso dall'acloolo etilico? Forse l'ipa?
Si può usare l'hcl?

Penso di sì, a patto che i reagenti siano solubili. L'HCl può essere usato come catalizzatore acido.

Il cambio di solvente e la quantità di acido cambiano notevolmente la composizione del risultato.

Penso che sia meglio usare il metanolo

I love vape with TGK ... I think I can do:

1. We carry out isomerization in ethanol with acetic acid for 12-24h.
2. After - we evolve all ethanol and acetic acid
3. Pour the resin with a mixture of glycerol and propylene glycol, dissolving gravs completely
4. Pour into a comfortable jar and smoke

The issue of health safety - alcohol and acetic acid should clearly not be synthetic - only food (We make THC from the CBD using trembling and sugar, aahahhaha)

Experienced isomerization specialists - what do you think? Is it worth a try?

You do not have to evaporate it. You can dilute with water and separate the oil if you use ethanol.

Hmmm... Of course!
And question

If I use AcOH in concentration about of 70-80%, It get to start isomerisation?

Now.... I can't get or make 100% acetic acid((

Then you need 7.5 (70%) - 6.5 (80%) mL of acetic acid soln. per ~100mL of ethanol (approximately).
Excess ethanol is necessary for the reaction to go well.
The resulting solution will take 5-10 g of cbd powder, nothing more.
Heat up to 70*C and boil at least 2 hours.
Dilute with water and collect the resulting oil.
You can write us about your results after.

I have wanted to do this for ages but have been holding off as I don’t have p-tsa, however, if d9 is generally done with a catalytic amount of HCl, that would be MUCH easier.
Is it literally a case of chucking it all in, letting it react for ages at RT (12-24h I think I heard), quenching, extracting?

Seeing as THC is by far the drug I use the most, it would make sense for edibles or whatever. Doubt I would want to vape it though. Never was a huge fan of vaping distillate as it just screws my tolerance.

It looks pretty easy though

Yes, it looks simple. That's why I want to try it!.. I'll write when I do it, there will be another report

If you use HCl for conversion, then heating is required.
