Here’s the question… Can phosphorus pentoxide be used as a good catalyst for reaction? instead of phos acid
Have anyone tried it? Want to try? I for sure heard that some people use it as drying agent during reaction in reactor instead of sieves. (interesting how that went)
It for sure will creates some THC, but % and d8\d9 ratio , impossible for me to test…
only concern is unknowns that may appear “if” this reaction is unsafe.
heptane as solvent (probably should be dry),
60-70c as Rogue once wrote about phos acid reaction.
inert gas
It will work but hard to tell how well
One of the drawbacks of phosforic acid is the volume needed (20% by volume )
I used personally dried phosforic acid and then added phosforic pentoxide to top it of making sure that as much of h20 was quenched prior to reaction
If you are gooing to use pentoxide only a small amount will hydrolize to phosforic acid and whatever pentoxide that did not grap water
Will very likely stay a solid powder
And even maybe clump in the heptane solution
The reaction has always been dictated by stirring speed of 2 immisible liquids
How well it will work by mixing a solid with your heptane/cbd solution I don t know at the % of pentoxide needed if it will react sufficiently
(no one complained on that tip about pentoxide in RXN vessel)
I get that it’s probably a very small amount, and relating on “someone said something” in chemistry doesn’t mean much. But still, Rogue always have good ideas, probably it’s one of them.
Phosphorus pentoxide is far stronger than sulfuric acid as a dehydrating agent.
Cbd has two hyroxil group which will be dehydrated.
Roguelab is using phosphorous pentoxide for drying his phosphoric acid and not directly in the reaction as a catalyst.
This is a big differrence..
I indeed do not filtering I add directly to the Rxn vessel with solvent cbd and my oven dried phosforic acid my adding amount should be around 3 grams to this 5 liter mixture
Since the vessel is glass I have a fairly good visual of solids in the vessel by pointing a laser treu solids light up
You will need hefty stirring thou to get a homogeneous solution with 2 liquid inside that do not mix I run a 2700 rpm mixer on the unit
Ran actually since I have given up on phosforic acid some years ago it s way to finicky
It makes great D8 but for 9 it s a bitch
I have had same thougts on pentoxid, but i do belive it will either be way to reactive or wont do much at all.
I have made phosphoric to dry to isomerize, so i beleive some h20 is necessary for any type of reaction.
If h20 is in excess then you will make D8, if temperature is to high you will make D8.
You need to convert your phosphoric acid to something much dryer, but still retain functional groups of h3po4 if you want D9.
Particle size and stirring is key, you want a catalyst with nice soft hands to reconstitute your cbd to D9.
In my mind it is a kineticly driven process, and the energy you give the process (stirring,heat,ph) will dictate if you get D9 D9/D8 or mystery soup.
The beuty of using this catalyst is a very pure and stable product, with no need for distilling as it wont make any unknown/not wanted cannabinoids, if done correctly.
I may’ve explain myself badly - they ofc can do so,
But decent amount of people use those reagents coz it’s easy, like EU black market, SOP’s on them exist since CBD isom. trend - with ok yeild and end-product safety, IF it’s done right.
No they will not
H2So4 has plenty of side reactions but 60% D9 is doable
Hcl is due to the two step process tedious but actually one of the highest possible route s
Pass hcl gas treu alkane cbd solution and you get d8 in 95%+ now react this solution with
Potassium tert butoxide or amylate and you get
95+ D9
I have tried a lot of pathways to shred thc for safety reasons when extracting cbd
Yes h2so4 in overkill amounts shreds it but NOT below 0.3%
