I tried smoking the light solids on the bottom and it just turned into a white crust kinda like when you smoke DMT so I assume the solid light stuff is garbage

JoeShitMost likely it is sodium salts. You can show the photo of the CBD, what is it quality? What hydrochloric acid use? If everything is clean and high-quality, most likely the temperature is high and stirring may not be enough.

Attached are my reagents, 2nd photo is the garbage that was on the bottom and the last photo is my product drying. I used citric acid and boiled it for 8 hours with the reflux running.

What state of CBD are you using, your product seems very impure

I recommend that you use pure CBD isolate powder, as full-spectrum extracted CBD is often dark in color and contains many lipids, which can interfere with isomerization reactions and make it difficult to separate products

Usually pure CBD powder lends itself to isomerization, I don’t know how pure the process goes with oil

does this look like a good product to use?

JoeShitCan you ask them what purity it is?
Usually, if it's isolate, it should be good to go, but the fact it also says "broad spectrum" confuses me a bit.

CBD isolate is the best substrate

Hey OP!
I currently hold only ethanol mixed with IPA (75%, 7%), will I have to get a hold of the ethanol or use vodka or something? To my own knowledge, I cannot see any way that the IPA would fuck anything up, however I thought I might ask instead of fucking around to find out.

You can use this mixture, after the reaction make sure you don't have isopropyl alcohol in your product

Need some assistance and a bit help regarding the following:

1. Wether the reagents that I had used, could have any negative implications on the product and if so, how to fix it during the isomerzation of CBD to psycho active cannabinoids.

2. The by-product that I've made

3. Calculation of potency of end product.



1) First i soaked about 5g CBD skunk (8%CBD) with 100ml Propan-2-ol (isopropanol)
inside a glass container with a lid and put on freeze in the freezer for a couple hours also I stirred the glass container a couple of times to extract the tricomes. After freezing the container, I then poured the 5g of CBD flower mixed with Propan-2-ol into another glass container (so that no troubles will occour in the 70°c water bath). Before adding the glass container into the bath, I put in about 100ml Acetic Acid (32% vol).
During the water bath, I added another lid upon the lid of the glass container. I used the second layer for placing ice cubes as to compress and chill the vapours untill they fell to the mix again. After the reflux session I was to separate the acid from the propanol, I just could not get ahold of alkaline water, so I just used regularitet water saturated with natron as for making the water more basal, making the pH rise.

2) The solvents did a reaction, leaving a layer brown/redish colour on the top, and a pale laver pn the bottom. Assuming the acid had absorbed the natron, I separated the two layers. However when dried, the solution I separated turened into rocks and flakes with a gourgeos orange, light red color, but that is not oil... What is this and can would it be dangerous to put in a pill as an edible for example? I am quite sure, its left over natron, however I just wanted to hear the smartest forum on earth about it anyway to be sure and maybe learn a couple things.

3) I am quite experienced in concentrate manufacturing, however calculation of potency is a bit hard imo. Is there any math equation for this and is there any differences in regards to determination of the percentages of potency? And does the equation differ if for example the product is made from CBD isomerization?


Best regards, Otcavians lost legions.

For isomerization, you need a pure CBD in the form of a powder

William DampierI used flowers, it sure got me high. As if i just smoked 5 blunts in a row, but without feeling dizzy and feeling dry in my mouth. I feel giggly AF, mostly relaxed in a form of body high, yet not feeling heavy and still doing my work. I looked up THC delta 8 and 9, and my experience as of now is just as descibed on the web.

However next time, I will try using cbd powder (99%). But just saying, it worked fine for me using flower, I even infused my flower with it afterwards jajaja

I have a question regarding the extraction of CBD.
How exactly do you extract it ?

Isomerization of CBD to THC using citric acid

Please be safe, at least pretend you are a professional chemist when doing the experiment, wear glasses and gloves, and have a fire extinguisher handy

It is important to note that this process is designed to use readily available materials and reagents and to convert CBD to THC as efficiently as possible, both in terms of yield and time efficiency, and is not comparable to professional laboratory techniques.

Reagents.
Citric acid
CBD
Distilled water
Sodium bicarbonate or sodium carbonate
Non-polar solvent

Equipment:
Small flask (do not fill a boiling flask more than half full)
small leibig condenser (200mm will be fine)
Small pump for condenser, aquarium pump can be
Small tube to fit the condenser fitting
Small bucket to put the pump into
Heat source suitable for your flask, preferably a heating jacket with magnetic stirring
PH test strips
A scale accurate to the gram
Dispensing funnel


Isomerization.

Determine your batch size and then determine how much water you want to use. You can go as low as 1gr H2O:1gr CBD, but you can also use more water to make the mechanics a little easier. For 1g batches I usually use 5g of water, for 5g batches I usually use 10g of water.

Add the desired amount of distilled water to the boiling flask using a small stirring bar. To do this, add at least 15% by weight of water to anhydrous citric acid, food grade. (So 1g of water will contain 0.15g of citric acid, it does not matter how much CBD you use). Attach the reflux condenser to the flask and secure it with metal clips and tube clamps. Fill the condenser and leave the aquarium pump running continuously. Turn on stirring to ~75 rpm, heat to ~120C, and bring the solution to a boil. Reflux for anywhere from 4 to 12 hours, depending on the CBD/D8/D9 mix you want. The longer the reaction runs, the more D8 you get and the less D9 you get. I prefer about 8 hours. You can run small batch tests to see what reflow times will yield the product you like. If you want 100% D8, run the reaction for 10-12 hours or until the test is negative.

Post-treatment.

Neutralization: Once the allotted time is up, turn off the heat source and allow the solution to cool to room temperature. Remember, your target is insoluble in water and is a solid at room temperature. After cooling, your flask should have large chunks of solid product floating on top of the water and clumped against the flask walls. You neutralize the citric acid with some sodium bicarbonate (3 moles of sodium bicarbonate to 1 mole of citric acid). You can add the bicarbonate directly to your solution and test the pH, or prepare a concentrated bicarbonate solution and add it to your flask, it makes little difference. Test with pH paper to confirm ~7 pH (does not need to be exact, 6-8 is fine).

Extraction.

Next, in this flask, add a portion of NPS. you will need to experiment to see exactly the smallest amount you can use, but your target molecule is readily soluble in DCM or EtOAc at room temperature. for a 5 g batch, I usually use ~20-30 mL of DCM. spin the NPS and you will see that your product has dissolved. Separate the aqueous phase and discard (I do this in a separatory funnel). Wash the NPS with an equal amount of dH2O (20ml of NPS with 20ml of dH2O) to remove any impurities physically trapped/entrapped in the product. Re-separate. If the organic phase becomes cloudy, it has absorbed some water. Dry with MgSO4 until the solution is clarified again. Decant or filter to remove MgSO4.

Isolate the product.

Your product is now dissolved in the NPS. Ideally, you can extract and recycle this NPS, thus significantly reducing the cost and environmental impact. If this is not an option, you can simply heat your solution to allow the NPS to evaporate. Perform this operation in a well ventilated area
Uncle Lee
both DCM and EtOAc are carcinogenic, any safe replacement ?

what do you mean by "NPS" ?
