Jeg kogte CBD og tilføjede ved en fejl NAoh til blandingen, jeg tror, at isomeriseringen stoppede. Der blev dannet 2 lag, kan nogen fortælle mig, hvad der blev dannet? Er det en god måde at udvinde THC-ekstrakt på?

Jeg bruger methanol og HCL

Hej, på hvilket tidspunkt har du tilsat NaOH?

Svaret kan gives ved hjælp af HPLC-analyse.

Efter 2 timers isomerisering blev der dannet en olie, men den har en ubehagelig lugt, og jeg ved ikke, hvordan jeg skal rense den.

Da jeg tilsatte Naoh, blev de to faser adskilt, og jeg tror, at reaktionen stoppede. Jeg har prøvet at vaske den på mange måder, men jeg kan ikke slippe af med den dårlige lugt.

baser omdanner cbd (thc bliver ikke omdannet) til nogle quinon-derivater. jeg mener, at forskellige opløsningsmidler kan bruges til at adskille det fra thc, men jeg kan ikke huske hvilke, og i hvilken litteratur det blev beskrevet, også fordi det er grønt (går jeg ud fra), og nogle planteimpuritter kan også oxideres.

Hvad er bedst, eddikesyre eller saltsyre? Jeg har en olie tilbage med en modbydelig lugt, som jeg laver for at rense den eller udtrække den rene cbd loas fra methanol

Toluen ved stuetemperatur og p-toluensulfonsyre kan bruges til næsten ren delta 9, og andre opløsningsmidler med varme resulterer i delta 8.

toluen kan være svær at fjerne, men 44 timer (48 timer vil resultere i lidt mere omdannelse, men ca. 10 % delta8) omrørt 10 % ptsa og nok toluen til at opløse det, derefter oparbejdning.

Når man tilsætter vand mættet med NAOH for at modvirke syren, kan jeg ikke fjerne det hele, og hvis jeg tilsætter for meget vand, bliver den øverste fase sort. Hvordan kan jeg lave ekstraktionen? Hvordan fjerner jeg syrelugten? Jeg har prøvet at rense den med destilleret vand, men det virkede ikke.

Jeg har brug for hjælp med dette.

Hvilken PH skal jeg lade THC'en have? Kan jeg bruge butan eller toluen til at rense THC?

Metoder, der bruger katalytiske mængder syrer, har etableret sig bedre end i dette emne. Med pTSA 10% mol i DCM (delta-8) eller med HCl 0,05% i ethanol (delta-9)

Kan man bruge en anden alkohol end ethylaclohol? Måske ipa i stedet?
Kan hcl bruges?

Det tror jeg, så længe dine reagenser er opløselige. HCl kan bruges som en syrekatalysator.

The change of solvent and the amount of acid greatly changes the composition of the result

I think it is better to use 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

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.
