Vařil jsem CBD a omylem jsem do směsi přidal NAoh, myslím, že izomerizace se zastavila. Vznikly 2 vrstvy, může mi někdo říct, co vzniklo? Je to dobrý způsob extrakce THC extraktu?

Používám metanol a HCL

Dobrý den, v jaké fázi jste přidali NaOH?

Odpověď může dát analýza HPLC.

Po 2 hodinách izomerizace vznikl olej, který však nepříjemně zapáchá a nevím, jak ho vyčistit.

Při přidání Naoh se obě fáze oddělily a myslím, že reakce se zastavila. Zkoušela jsem to vyprat mnoha způsoby, ale nemůžu se zbavit toho nepříjemného zápachu.

báze převádí cbd(thc se nepřeměňuje) na některé chinonové deriváty. myslím, že k jeho oddělení od thc lze použít různá rozpouštědla, ale nepamatuji si, která, a také v jaké literatuře to bylo popsáno, také proto, že je zelený(předpokládám), některé rostlinné nečistoty se také mohou oxidovat

Co je lepší kyselina octová nebo kyselina chlorovodíková? Zbyl mi olej s nechutným zápachem, který dělám, abych ho vyčistil nebo extrahoval čistý cbd loas z metanolu.

Pro téměř čistou delta 9 lze použít toluen a kyselinu p-toluensulfonovou při pokojové teplotě a jiná rozpouštědla s teplem vedou k delta 8

toluen může být obtížné odstranit, ale, 44h(48h povede k o něco větší konverzi, ale asi 10% delta8) míchá 10% ptsa a dostatečné množství toluenu k jeho rozpuštění, pak zpracujte

Když přidám vodu nasycenou NAOH jako protiváhu kyseliny, nemohu ji celou odstranit, a pokud přidám příliš mnoho vody, horní fáze zčerná. Jak mohu provést extrakci? Jak mohu odstranit zápach kyseliny? Zkoušel jsem to čistit destilovanou vodou, ale nepomohlo to.

Potřebuji s tím prosím pomoci

Jaké PH mám nechat THC? Mohu k čištění THC použít butan nebo toluen?

Lépe než v tomto tématu se prosadily metody využívající katalytické množství kyselin. S pTSA 10% mol v DCM (delta-8) nebo s HCl 0,05% v ethanolu (delta-9).

Myslím, že ano, pokud jsou vaše činidla rozpustná. HCl lze použít jako kyselý katalyzátor.

Změna rozpouštědla a množství kyseliny výrazně mění složení výsledku.

Myslím, že je lepší používat methanol

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

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