Приготвях CBD и по погрешка добавих NAoh към сместа, мисля, че изомеризацията спря. Образуваха се 2 слоя, може ли някой да ми каже какво се е образувало? Това добър начин ли е за извличане на екстракт от THC?

Използвам метанол и HCL

Здравейте, на какъв етап сте добавили NaOH?

Отговорът може да бъде даден чрез HPLC анализ.

След 2 часа изомеризация се образува масло, но то има неприятна миризма и не знам как да го пречистя.

При добавянето на Naoh двете фази се разделиха и мисля, че реакцията спря. Опитах се да го измия по много начини, но не мога да се отърва от тази лоша миризма.

базите превръщат cbd (thc не се превръща) в някакви хинонови производни. мисля, че за отделянето му от thc могат да се използват различни разтворители, но не мога да си спомня кои, също така в коя литература е описано, също така защото е зелен (предполагам), някои растителни примеси също могат да се окислят

Коя е по-добрата оцетна или солна киселина? Имам масло, останало с отвратителна миризма, което правя да го почистя или да извлека чист cbd loas от метанол

Толуенът и р-толуенсулфоновата киселина при стайна температура могат да се използват за получаване на почти чист делта 9, а други разтворители с топлина водят до делта 8

толуенът може да е труден за отстраняване, но, 44 ч.(48 ч. ще доведат до малко по-голямо превръщане, но около 10% делта8) се разбърква 10% птс и достатъчно толуен, за да се разтвори, след което се обработва

Когато добавям вода, наситена с NAOH, за да противодействам на киселината, не мога да я елиминирам цялата, а ако добавя прекалено много вода, горната фаза става черна. Как мога да направя екстракцията? Как да премахна миризмата на киселина? Опитах се да го почистя с дестилирана вода, но не се получи.

Имам нужда от помощ за това, моля.

Какво PH трябва да оставя на THC? Мога ли да използвам бутан или толуол за пречистване на THC?

Методите, използващи каталитични количества киселини, са се утвърдили по-добре, отколкото в тази тема. С pTSA 10% mol в DCM (делта-8) или с HCl 0,05% в етанол (делта-9)

Мисля, че е така, стига реагентите ви да са разтворими. HCl може да се използва като киселинен катализатор.

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.

The reaction time can be a little longer than we wrote before. You need to examine to choose the best time if you do not have the opportunity to make an analyst.

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.
