TEK Converting CBD to THC using only Zeolite and heat.

This topic contain a TEK
Hey again,
This time I made a bigger batch and tried out a few new things.
1. Decantation
It makes a huge difference. Just let your mixture sit overnight, then either pour it into another container or draw it out with a syringe. In my opinion, this step improves the final result even more.
2. Filtration
First, I used sterile gauze to separate the larger zeolite particles. After that, I filtered it with 0.45 µm syringe filters. They worked really well but got clogged pretty quickly, so I changed the filter every time I felt resistance, just to avoid even the smallest particles getting through.
3. Final product
I ended up with a very dark, sticky resin. I mixed it with PG in a 30/70 ratio and filled my carts. They burn fast, but just two big puffs get you really high. Next time I’ll try to make a stronger mix. I was a bit worried about how the new carts would handle it, but they seem to work just fine and could probably take even more.
4. Edibles
So far, the strongest ones. from this batch.

I have a very sore throat when smoking WAX. Is it because I don't filter WAX from zeolite? I only settle the mixture for 6 hours.What else can cause a sore throat when smoking. I use isopropyl alcohol instead of ethanol. But I first evaporate the alcohol, and then mix the mixture with water so that the water takes the rest of the alcohol. Then I pump out the water with alcohol with a syringe
I just store it in a regular 10 ml plastic e-liquid bottle. If anything separates, I simply heat it in water to around 40°C, give it a shake or stir, and it works fine again. Don't use higher temperatures, though—it could release microplastics from the bottle.
Personally, I haven't experienced a sore throat, but yeah, the coughing can be intense—pretty typical with stuff like this. Dutch HHC used to rip my lungs apart too. But no actual pain, honestly.
If you're getting a harsh hit, it could be leftover alcohol in the wax. I usually keep heating it for 20–30 minutes after I think it's fully evaporated, just to be safe. It could also be the zeolite—was your solution crystal clear before heating? Did you notice any particles floating in the mixture? Or that might be just some random impurities.

Yes, it is possible that these are residues of zeolite or isopropyl alcohol. I try to settle the mixture so that more zeolite can sink to the bottom. Then I evaporate the alcohol without raising the temperature, it takes more than 24 hours. After that, my WAX still contains some alcohol. I add water to mix with the alcohol and I can remove it and dry the rest of the WAX.
How to filter the mixture from zeolite? I will be very happy

If you want to make an investment look for a buchner funnel suction filtration kit and use the 10μm pore diameter paper filter (also sold as "slow flow")
The kit's cost is under 100$, and can be found on sites like ebay.
There is however a method posted earlier in the thread using tightly rolled kitchen paper and a funnel, which works well.
Its also a good idea to get zeolite with particle size of ~100μm (bigger size = easier filtration)
Stay safe and DYOR.
I ordered paper filters for the Büncher funnel and the Büncher funnel itself. Will I be able to filter without vacuum? I don't speak English and I use the services of an interpreter. I can't understand what kitchen paper is.
In the thread above, it says that you are using aluminum cans for isomerization. And I used them. As a heat source, I used a magnetic stirrer with a heating function. Zeolite and CBD were 1:1. Periodically, in the process of isomerization, I measured the lower surface with a pyrometer, the temperature sometimes reached 180-190 degrees Celsius. Isomerization took 30 minutes. I also used argon. I opened the lid for the first time with great effort. The second time I had to break the jar. In both cases, the zeolite/THC mixture did not melt. The first time the mixture was dark gray, the second time darker. I mixed the mixtures with isopropyl alcohol. After settling, the mixture became a little lighter, zeolite sediment precipitated. But the color remained the same gray.
Before that, I had isomerization in a laboratory flask. During isomerization, the mixture melted and became homogeneous. The color was brown. I dissolved it in isopropyl alcohol. After settling the mixture, the zeolite layer settled. The top layer was the color of honey, and it was also transparent. I put the top layer on a plate. And I put it on the balcony for 24-30 hours so that the alcohol evaporates. Then I poured water to mix with the rest of the alcohol, then pumped out the water. I got a fairly viscous WAX.
Why didn't I isomerize in aluminum cans? Perhaps I am using the wrong cans? Please send your photos and a link to the store where you bought them.

Is this method of filtration from zeolite the most suitable method? Is there a better way?
Short path distillation would be the best way.
What ever you do, you need to take a highpowered torchlight and shine it through your filtered Liquid. If you See any particles, its not safe to consume!!! This step is not optional!!! You can really fuck up your lungs consuming this when there is any zeolite left, very possible that it leads to cancer.
Tell us about the distillation method. If the isopropyl alcohol evaporates, will the WAX volatilize along with the alcohol?

Pink can be a good sign of D8 THC ... read back to page 2 of this thread for details: TEK - Converting CBD to THC using only Zeolite and heat.

Tetrahydrocannabinol
Nice note, however, i would like to point out that the carcinogenic zeolite known to cause mesothelioma and lung cancer when inhaled is zeolite erionite, a fibrous type.
Fortunately for us, the isomerization method requires zeolite clinoptilolite, which is noncarcinogenic and considered much safer,
But of course safer is not safe, all types of zeolite are basically tiny aluminosilicate crystals, so inhalation of any zeolite dust must be avoided.
Z. Clinoptilolite while not carcinogenic, is still known to cause respiratory irritation and damage upon significant exposure.
(for anyone interested, NCBI article on Z. Clinoptilolite's safety and medical applications: here )
Keep it safe and DYOR.

I'd encourage you to read from the beginning of this thread where this sort of thing is discussed, a brief summary is:
The process converts CBD to D9 then further to D8 and other cannabinoids, encouraged by moisture and oxygen.
Unless you can really ensure identical conditions throughout the mass of the mix when it's in the oven, you are likely always going to overshoot a bit for some of the mix if you're aiming for the most conversion possible. The thin edges of the mix pack will heat up more quickly than the very middle, for instance, and will go further down the chain of reactions.
Argon will displace oxygen and make the overshoot less likely.
It might also be that the pink is a strong colour, so will easily dominate yellow, even though there a greater proportion of D9 than D8 in there. Colour alone is a poor test.
If you really are against D8 in any form and would rather you had less D8 but more CBD in the end product, then cutting the times and temperature down a bit would seem to be the way to go, so that you 'undershoot' and little or none of the converted D9 gets further converted.
( Disclaimer: I am no professional chemist, the above is my "vibe chemistry" gleaned from the discussions in this thread, I welcome any correction to misconceptions )
