I’m sure if you legitimately have questions about organometal catalysts, people will be happy to help you out and make sure you understand the safety aspect. @Ennui is more concerned that some idiot is going to read that triisobutylaluminum is like some shit that you just chuck in a flask and make d9, that they’ll go order some from sigma, and then they’ll set their kitchen on fire with it

Not mentionning the possibilty of basic math error then, as seen above…

Hello @Roguelab, 98% D8 is a great result!
Do you know the composition of 2% remain? Are those unknowns or cannabinoids?
In another post also talks about diethyl ether and phosphoric acid for D9, what% of D9 can be obtained by this method?
D9/Cbd remaining 2 %
95% D8 and higher

Thank you for your answer.
Does anyone know how much tosic I should use for 100g cbd isolate and should I times it by 10 for 1kg. Cheers

1.5% by weight of Cbd is enough for most rxn even at room temp

Cheers, what about reflux temp using toluene
Ptsa acid is strong at it s task and will isomerize in most solvents any where from -10c to bp of solvent
Now the key in keeping a gold color with ptsa is adding acid at no more than room temp and keeping it below 35 C when adding this will avoid a blood red rxn

Cheers so best to stay at room temp, is it impossible to get clear with ptsa
Time and temp go hand in hand
The hotter the faster
Every 10C higher go s 2x as fast

You can not get clear out of the flask at once but if all you made was D8
Distillation will make it clear and waterclear if
You understand distilling well
There are some tricks floating around to make water clear with some minute amounts of powders in the flask

I’ve got a kugelrohr and know a bit about distilling but mainly other things, first time doing anything related to cbd/thc etc

Stir speed as well 
I’m running cooler and cooler, each time ramping stir speed higher and higher each time, it negates time a bit.
Higher the heat, the higher the “unknowns” I’ve seen as well.
Look at it this way… cold preserves just about everything. But, a virus is more efficient in the cold then in the heat (not meaning transmissibility, just in overall individual infection spread).
I’d like to see more of an agitator then a stir for better dispersion of the acid.
Working on that now

I have always said that stir speed is crucial
In acid/immisible solvent rxn
Believe me I have taken it to the max 2660Rpm on a 80L reactor at room temp
The rogue way 
You do need baffels inside the reactor thou!
To break the vortex
Thinking that pumping the solution acid/Cbd/solvent might make a better mix thou

Like a solvent recirculating pump at high velocity (thinking like a Haskel closed loop pump for active recovery)?
I’m thinking an agitator (like a washing machine. The only thing spinning used for is getting the excess water out ). Spinning, to me, will just let everything chase itself, taking FOREVER to make constant contact enough to isomerize.
Now, to find a rated agitator pump 
Edit: that motor is INSANE

I have so far used >99.9% CBD-isolate in 96% Ethanol with HCl at pH ~1.5 reflux close to boiling temp of Ethanol for 36 hours, finally neutralized with NaOH, and Ethanol distilled off in a Rotovap, and last remains of fluids removed with a vacuum drying oven. The last HPLC shows a total detectible percentage of known cannabinoids = 69.7% where THC9 = 27.7%, ISO-THC8 = 22.7%, THC8 = 11.7%, CBN = 0.13%. According to Gaoni Y., Mechoulam R. “The iso-tetrahydrocannabinols” and “Hashish—VII.”, and Kiselak T.D., Koerber R., Verbeck G.F. “Synthetic route sourcing of illicit at home cannabidiol (CBD) isomerization to psychoactive cannabinoids using ion mobility-coupled-LC-MS/MS”, the unknown remaining cannabinoids are most likely Ethoxy HHCs as Ethanol was used.
The reason why I’ve used Ethanol and HCl is because once neutralization has been done with NaOH, the remaining byproduct is only NaCl (salt), so it’s perfectly safe.
Does anyone have any experiences and results to share here when using Ethanol + HCl?

I was often wondering- what about a rotovap with beads that won’t degrade?

Edit: I guess I clicked on a quote that I didn’t mean to 
A possibility… need a really big roto and a shit ton of beads. That’s where the discussion about making your own beads infused with certain acids.
Looking at how the transmissions on washing machines work, that’s also a possibility as well. Built underneath of a reactor motor, a bit of a change to the fins on the spline into the reactor…
Both are have great possibilities
