This Sounds great!

Do u buy the ethanol/hcl or do u make it Yourself By a floating (dry) hcl gas to androus ethanol?

Love

Good Job, when waterclear turns to purple under the influence of air and/or (sun-)light Then u have nearly 98-100% pure D9!
So u Play the Game perfectly!

So u have to store it under vacuum or the Best way in a syringe so u Safe it from air.
And then store it in dark. Perfekt is fridge or best for Long time freezer.

Pure D8 should Not turn to purple/red/gold AFTER destill. After iso, there could be a colour.

Love

I’m located in Europe (EU) and here it’s possibe to buy pure (non-denaturated) 96% ethyl alcohol from many (but not all) EU-countries without any restrictions. Most of the alcohol is then restored using a distiller, and the last part of the alcohol and water is finally removed using a lab vacuum drying oven.

Refluxing too long with EthOH and HCl results in lower concentration of T8/T9 and overall lower concentration of known cannabinoids. On the other hand, if the reflux is done to short in time, then not all CBD is isomerized (there will be remains of CBD left). PH also seem to have an impact - too low and the process goes much faster, is complete (no remains of CBD) but then also more of the CBD turns to unknown isomers, but if the pH is not low enough then the entire process takes longer time, and there are remains of CBD. So it seem to be a balance between mainly time + pH. Heating temp speeds up the process, but I have so far not seen any differences if the alcohol is near its boilinjg temp of 78.4 C, or about 60 C.

Hey! Have you guys tried ozone isomerization?

I got a Ozone generator with a bubbler from Wish.

Found this pretty cool reasearch on how to convert CBD to THC with Ozone!

EXAMPLE I A quantity of dry hemp chaff was placed in a bag together with an operative ozonegenerating machine (BESTEK 03 ozone generator/air sterilizer model: BTAS807) for approximately 1.5 hours. A sample of each of the treated and the untreated hemp was pulverized and prepared for smoking using standard methods known in the art. The sample was smoked by 15 professional smokers trained to recognise a psychoactive effect prior to the experiment. 14 out of 15 panellists confirmed a psychoactive effect of the treated sample but not the untreated sample. The sample is further subjected to NMR/IR spectroscopy and presence of A9-THC and A8-THC, as well as other ozonated cannabinoid products confirmed.

EXAMPLE II

Ozonation of hemp was carried out as per Example I above. The ozonated product was sampled by a subject suffering from chronic pain and anxiety. The product was firstly smoked by the subject. The subject confirmed amelioration of symptoms, in particular lessening of pain. On a separate occasion, the subject mixed the product with edible oil and ingested the product. The subject again confirmed amelioration of symptoms, but more long-lasting than when smoked.

EXAMPLE III

Ozone was produced from oxygen under electric discharge conditions. Before being fed into the ozone generator, oxygen was dried with Mg(CIO4)2. The solvent was CCI4 (reagent grade). Prior to performing the reaction, substrate (hempseed oil) was treated with an ozone-oxygen mixture (~10% O3) for 30 min for decomposing the possible active impurities, held over calcium chloride, and distilled. Ozonation was carried out in a temperature-controlled bubbler under steady-state conditions. The reaction was performed in the temperature-controlled sample cell of a spectrophotometer. An ozone-oxygen mixture was passed through the sample cell with a substrate solution until the necessary O3 concentration in the solution (1.7 χ 10-5 to 6.8 χ 10-4 mol/l) was reached. The blank in the reference cell was a solution containing the same substrate concentration. The substrate and ozone concentrations in the sample cell were chosen so that the substrate was at least in 100-fold excess over ozone. After the necessary O3 concentration was reached, the sample cell was sealed hermetically and the ozone consumption rate in the cell was monitored spectrophotometrically. Using this procedure, we determined the monomolecular ozone disappearance rate constant (kmono)· From the dependence of kmono on the substrate concentration, it is possible to determine the stoichiometry of the reaction and the ozonation rate constant at the given temperature.

EXAMPLE IV

Conversion of CBD to A8-THC. CBD (300 mg) was added to dried p-toluenesulfonic acid (30 mg) in toluene (15 ml), under O3 atmosphere. In this example, the mixture was refluxed (under O3) for 1 hour, although other time periods may also be used, as discussed below. It was then diluted with ether (20 ml) and poured into cold water. The upper layer was separated, washed with aqueous 5% NaHCO3, then with water, dried over MgSO4 and evaporated. The viscous oil showed mainly one spot on TLC (using 20% ether in petroleum ether as eluent). HPLC, on the crude oil, showed the presence of 87% A8-THC. The oil was chromatographed on a silica gel column (6 g). Elution with 5 to 10% ether in petroleum ether gave a fraction (244 mg, 81%) of A8-THC 98.8% pure. When the reaction was carried out using various reflux times showed the presence of 79.37% A8-THC (15 minutes), 81.9% Δ8-THC (30 minutes) and 84.7% A8-THC (2 hours).

EXAMPLE V

Conversion of CBD to A9-THC. BF3Et2O (50 ul) was added, under ozone atmosphere, to ice cold solution of CBD (300 mg) in dry methylene chloride (15 ml). The solution was stirred at 0° C for 1 hour. Saturated aqueous solution of NaHCO3 (2 ml) was added until the red colour faded. The organic layer was removed, washed with water, dried over MgSO4 and evaporated. The composition of the oil obtained (determined by HPLC): trans- A8-isoTHC 27%, A9-THC 69.7%. The oil was chromatographed on silica gel column (20 g) and eluted with petroleum ether followed by graded mixtures, up to 2:98 of ether in petroleum ether.

The first fraction eluted was the A8-isoTHC (30 mg, 9.5%) followed by a mixture of Δ8-ίεο THC and A9-THC (100 mg). The last compound to be eluted was the A9-THC (172 mg, 57%). The purity of A9-THC (as determined by HPLC) Was 98.9%. It is of note that when the reaction was carried in the presence of MgSO4 (120 mg), the composition of the oil obtained (determined by FIPLC) was: trans- A8isoTHC 21.15%, A9-THC 56.7%.

While the preferred embodiments of the invention have been described above, it will be recognised and understood that various modifications may be made therein, and the appended claims are intended to cover all such modifications which may fall within the spirit and scope of the invention.

Had a few people I’ve talked to about ozone specifically & from what I gather is the rxn is almost impossible to stop till it’s completed. & you end up with this super hard black polymorphic style crude that has no cannabanoid content to it. I haven’t personally tried it, but this is from what I’ve heard.

Thank you for your answer.

I’m will try in the next couple of days to build a fluidized bed reactor and blast 200-300 mg of CBD isolate with ozone for 30-60 min and see what happens.

Iso with citric acid in EthOH for 36H close to boiling temp 78 C, then pH-neutralised with NaOH-solution and washed with distilled water resulted in a light yellow color. While using HCl in EthOH for 36H close to boiling temp, then finally neutralized with NaOH-solution and washewd with distilled water resulted in red-violet color.

Have you tryed it yet?
If you did, what results did you get?

Not yet I haven’t had time to try ozoning isolate, I need to first create a good reaction tube.

I did a test with CBD buds and ozoned it for 1 hour but I haven’t smoked it yet.

I would analyze them before smoking them

I do not have access to analytics tools :confused:

I just have to trust the patent text that it is safe.

Look up for cannabanoid testing facilities in your area or send to @kcalabs please don’t smoke these before knowing if the ozone has done something you don’t want to inhale or ingest.

You should not. :confused:
Patents and papers are rarely reproducible like that, and rarely detailed enough.

I wouldn’t smoke it…

But if you do… At least report back.

I searched some more about ozone and found this interesting article how ozone can be used to sanitise food.

Several researchers have been focusing on the ozone’s properties and applications, proving that ozone treatment technology can be applied to all types of foods, from fruits, vegetables, spices, meat, and seafood products to beverages.

https://www.tandfonline.com/doi/abs/10.1080/10408398.2017.1308313?journalCode=bfsn20

If ozone can be used with food stuff it should be fine to be used to convert CBD?

Nooooooooooo, this does not = that.

There’s a big discussion about toxic byproducts from the breakdown of CBD. If you are not a chemist and do not have access to analytics you should not be performing these reactions, and especially should not be consuming or giving out to anyone what you’re making.
