I have some liters of some distillate which I suspect to be converted and I am wondering if there is a way to fix the purple oxidation.
It goes form normal to insane purple in about an hour. Being from the Recreational THC market I do t have a lot of experience with something like this and would love to educate myself and others on something I haven’t seen before.
I did some searching but am horrible at gleaning the nuggets.
Thanks
The d8 is the giveaway for next time.
You can try adding back in some antioxidants, but it’d only slow down what’s gonna happen.

Why is it happening?
What can be done with the conversion to prevent this?
Only a slow down and not a fix?
Thanks for your reply. I appreciate all the info I can get
Fix to what end? To successfully scam unsuspecting customers by eliminating the purple giveaway?
Trash em. Do better next time
D8 pops up in regular distillate sometimes, the minors are unusual for a conversion. The only way to really tell is to test for the iso-THCs and conversion byproducts
Continue to leave it in the air with about 20% oxygen and it will continue to turn color until dark brown color is achieved.
Or just put it in a jar with argon on it.
100% spot on.
I’d also question the accuracy of the COA. While I’m sure it was done with best intentions, we are all more than aware of the conflict of interest labs are given when providing results. Along with tight time-tables, and the shear difficulty/time/cost needed in testing all these compounds. You need some really high end analytical equipment to detect some of them. The seemingly low concentration contaminants can cause a formulation to lack stability/shelf-life. The reaction is still on-going and things are changing. Oxygen is very reactive and weird PH issues, leftover reagents, and/or unique compounds can do unpredictable things. Its important to really know the whole supply line when sourcing product. Its a question of morality and ethics, but If it were me, I’d toss the lot and call it a valuable and expensive lesson. I stick to regular cannabis extraction. Conversions are the devil’s business(and pharmaceutical industry’s).
Or just let it go purple and market it as “Royal Purple Oil”
Didn’t make. A friend bought. Trying to help and understand the underlying causes.
I mean yeah, but usually that’s an indication of ph shenanigans or some acid (stronger than a carboxylic acid) finding its way into your decarb reactor, right? Like, one “normally” won’t see d8 pop on their disty tests.
But that does bring up an interesting question - “What’s the ph of the oil presented here?”
Don’t THCa-A and THCa-B occur naturally? Like, if you could tell the two apart easily with analytical equipment in-lab, that still wouldn’t be a confirmation of conversion right?
Excess heat/time and vacuum leaks can do it too
Treu
Looking at the numbers it seems a slight leak was in the path
Cbc and it s degradation product cbt
But this is a lot of discoloring in 1 hour
Ph swings either way will give a colored disty straight from the flask
So not it either in my opinion
Leaves reagents left in oil
Reagents left in oil often means no distillation has been preformed at all
Since most get seperated out by distillation
Wich leads me to
The rxn was preformed with alcl3
The aluminiumoxide / aluminiumhydroxide after quenching was not washed out properly
Aluminiumhydroxide can be basic
And it seems basic since basic makes purple and acitic makes pink
Ps a picture of a whole liter bottle might give some more hints
The problem is not the aluminium that causes the oxidation its the clorine bound to the thc that acts like a strong oxidizing agent when using alcl3 as catalyst.
You can just re distill it. To prevent. Backfill it with inert gas and double sealing can help prevent it.
for all the people saying d8 can be present on conventional d9 liters, did you grow the material which popped for d8 in the disty?
i still have never seen a conventional d9 COA that IVE BOUGHT OR MADE pop for d8 nor have i ever seen a conventional d9 liter start to turn purple.
i guess im just lucky.

Something that with all r and d I claim is deu to terrior
There are natural pathways for stronger acid uptakes by plants
Acids that I believe are responsible for the chemistry to flip the 9 to 8
Wonder if acid rain can have an influence lime stone statues dissolve over time deu to acid rain
And from experience I know that very very little of something can create D8
You can just re distill
If it s not cleaned up well redustilling or even plain heat over 90C will retract the disty with left precursors making it all D8
Thats interesting too… never thought of that and stuff like fire retardant around some of these outdoor grows.
i wonder if anyone running indoor trim and larf only sees this
we get d8 in our coa’s occasionally and dont even distill. decarbing under pressure or decarbing cured resin with a condenser can pop a little d8.
If I remember correctly, didn’t fire retardant convert to D10?
Your process is hydrocarbon?
Perhaps the d8 is from cannabanoids reacting with your filter media?
are you guys sure its not just cus it was a super dank purp strain?
Yes is can be fixed
