Oh, my bad 
Thank you.
Souds like a challenge Are they only detectable on NMR/MS then?
This is the ratio to 1kg of CBDP?
Actually I noticed this in CBD->THC trials. More solvent (10:1,20:1) did in fact complete the reaction with Ptsa much faster than 36hrs on paper, RT.
So milder, cooler conditions, allow to stop at the right time.

No cbd > thc I never tried cbd-p
For I consider it a synthetic cannabinoid
Wich are inferior ( for many reasons)

I agree on the synthetic part totally,
but I believe the processes should be the same. the longer chain doesn’t really affect any dynamics, or I should just wait and see.
The more I read - the more confused I get. There are so many variables, and all of them effect the reaction 
- timing
- solvent ratio
- temperature
- stirring effectiveness (actually this I think is linked with the solvent ratio somehow)
- catalyst’s stereoselectivity
- catalyst’s abundance
I really want to make a tests with HPLC results, but I dont know which variables to start first
What’s exactly the end product you Wich
Thc-p D8 or thc-p d9 ?
Either one will be fairly racimic 50/50 r and s
The colder you run it the less it flips
So alcl 3 makes sense but the cleanup won t be easy for a starter

I am having troubles with sourcing AlCl3 or Potassium tert amylate… Just noone seems to have it.
I would really like to get d9 since its (22±4/1.2) stronger?
I have had once in my life experience with LiAH4. Is is somewhat similar? In terms of “no water, at all costs”

A lot less dry is needed but not lithium dry
Which is where enzymes come into play…and presumably this one would need to be engineered.
We are poised to get really good at that…
Edit: @xdubr, I would also like to congratulate you.
@Shrimp is absolutely on point with
I can think of a couple or three other examples of folks who nailed their first question, but yours is absolutely one of best.

I really believe that timings are crutial, as well as I like the idea of kinetic/thermodynamic Labworks suggested.
CBD 5gr, pTSA 1%,
DCM 2:1 ratio (10ml), after 90 minutes:
4% unconverted CBD.

Ptsa dcm is a bad combo
Ptsa on hexane or heptane is beter
Cyclohexane also good
Could you elaborate on why is it a bad combo?
I am planning to do another run, but take samples every 15 minutes to see how it evolves
RT on Toluene gave me a worse conversion at RT after 48 hours
It s still pretty polar solvent
Not reagents - keyed membranes. I haven’t done it for this specific mixture. But I did quite a bit of this in the early 2000’s. Here is a good paper (google is awesome BTW) which gives excellent references behind the science of what I mean. Its references go back to the 80’s. The tech I was using was from the mid-90s. Looks like they have way cooler solid state and liquid state options now, available from Sigma and the like.

Smaller batches can still be done 10:1 in a 6L. Good luck!
You might consider trying your local university inorganic chemistry or organic chemistry department. The ones near me often have these and have them as part of their chemistry “store” meaning they are selling their over-stock stuff.
Not sure where you are… but it looks like you can buy some of these direct and ship to business in the US/Canada.
If your apparatus allows you to take little aliquots during the run, that will help when looking at time frame as the control. Seriously good to take them every 15. If you see big differences, take them every 5 or so to dial that in.
Something else I noticed myself was that solvent ratio mattered (with stirring, I never did without) because the temperature of the reaction was different from top to bottom of vessel. If you have indicators top and bottom you can see this a bit. Its not a huge difference, but I have seen this many times with many exothermic reactions.
This is one of the few rxn I advise to run on a steel vessel glass is a horrible heat transfer compound and you wantrouwen keep it stable

I will try using an overhead stirrer, but 10:1 solvent ratio seems a lot. I will try elaborating on my cold method. With tests every 15 minutes.

Well, if I had moneys to afford a tonn of CBDP/CBDV, I would definitely go for steel
But so far I could get my hands and poickets onto 1kg which I want to use wisely
