What do you mean by crazy high 2molar?
I am going back to ethanol and fosfor to get the D9 I was in the 40% 50% but i gues i missed out some important details. Moist is one of them

Look closely at the methods in Marzullo et al., they used a very high amount of pTSA.
In addition to all the influencing parameters we already know about (water, oxygen, timing, amount of acid, stirring,…), temperature control seems to me to be a decisive factor here.

I noticed that the temperature rises for a few degrees after a certain point. At the same time, d8 begins to appear. @roiplek Only now have I understood your explanation in this context.
If I understand this correctly, a constant and lower temperature should be able to inhibit or at least reduce the thermodynamic pathway?

You have it exactly.

I’ve noticed a color change at a certain point, my disty will go from yellow to red/black
After water washes it always comes out yellow

I did a run yesterday and decided to run cooler then normal to keep it under 65c. Took a bit longer. But I also ran 7 water first then to 9 and worked back down to 7 (to make sure the acid was neutralized).
Ran beam test every 15 minutes till I was satisfied it was converted.
Sending out for testing tomorrow to see where I sit.

That looks great! You mean 65c during reaction right @HeisenbergInd? Excellent work

Sould be in by now? 
my lab takes max 3/4 days with sending it thrue the post. Wish i had my own tester set,… each test cost every time 45 euro’s

Yes noticed if you don’t clean out all of the acid you get dark(er) disty So did you test the ph levels of the run off water? Like 7 in 7 out?
Wonder how you got the N heptaan out at 65C? with 12 cfm becource boiling point is 98,42 °C

He redistill after the reaction
I’m sure he went above 65c after the reaction was finished

Still a little yellow here. That was the hardest part for us was to go from this very very light yellow to completely colorless. Good luck tho! On the right track for sure

Can you dm me the lab?
I have to send my samples to Austria and the price is more than double of yours.
n-heptane is quite volatile and is rapidly evaporated at room temperature and under low vacuum.

Should be in today… typically 48/72 business hours but not sure with the virus shit and the holidays.
I can go water clear. Easier to achieve that with phosphoric.
pTSA just requires a deeper bed of B80.
Edit. After you make the B80 bed, add a layer of silica to the top of the b80 bed to achieve water clear easier with pTSA

@Kingofthekush420 is correct. Reaction never went above 65c. Then, filtered, roto, then distill.
I start with water at 9ph till it runs 9 then run 7ph till it runs 7 for 3 consecutive washes and comes out as clear as it did when it went in!
Edit: Ran beam test every 15 minutes as well to make sure that I stopped at the proper time once all CBD had been converted. Did not sweep with argon or pre dry my heptane as well. Working on temps with this rxn.
@Roguelab also mentioned keeping a constant temp and how the rxn will generate a large amount of heat (due to the kinetic reaction ie: molecules moving quickly creating heat) so I ran a heater/chiller to make sure I maintained that 65c
Edit x 2: Need more coffee before I try to post shit. I had more edits then kilos I ran this last round and probably still missed shit

The heat may rather be generated by certain step(s) in the reaction mechanism, which may be exothermic.
