agreed, except OP didnāt make or decarb the THCa in questionā¦
best option might be to try and pitch is as a feature.
or mix back some of those natural antioxidants using purchased HTE.

Oh crap I completely missed thatā¦.. so in other words we have no actual real knowledge of what the actual starting material is / was except for what the lab he got it from claims it wasā¦.. we all know how reliable that can be donāt we

I appreciate all the feedback. I finished up the hot scrubs yesterday and I was really happy with the end results.
Ill take some pictures tomorrow. Monday Iāll throw it in the rotovap and recover the pentane, then put it in the vac oven and weāll see how it turns out.
Totally not opposed to mixing back in some liquid diamonds or HTE (just saw that)
How much do you all think I need to add back for it to be effective. I have about 1750g of the purple stuff
Hahaha looks familiar 
Thats a nice stir plate!

What am I missing here?ā¦. Are you sure the product you are buying is exactly what is described and not something else?
IF you have/start with (actual) diamonds that are sufficiently pure you will run into the same problem as Iāve already described all over again
How well do you trust the company you bought it from?
Youāre not missing anything. I was going above and beyond to ensure a very good customer of mine got distillate. I didnāt anticipate this purple issue.
So from now on they will get liquid diamonds. Ill just have to make sure they are fully decarbed.
Whats that sayingā¦ no good deed goes unpunished or the road to hell is paved with good intentions lol something like that 
Or leave a little THCA in there. Helps prevent oxidization.

it seems to me that the pink and purple are a PH issue that seems to be brought on by oxidation. scrub it with perform 6000 and the purple issue should go away. other than that try to mitigate oxygen contact as much as you can especially when its hot or warm.
Its quinone formation
Cbd quinone is purple thc quinone is red which is why you can get different hues depending on varying levels of oxidation and actual cannabinoid content
I mean yellow distillate is generally oxidized which is why if you pull the plant early youll make lighter colored extract
then why does pure D9 thc turn purple when there is 0 cbd present? i agree the red/brown colors are from oxidation. i can store my decarbed thc isolate under a nitrogen blanket and it stays the same color, as soon as i introduce atmosphere it starts to turn purple, the hotter it is the faster it turns.
It wont if theres no cbd in it, have you ever seen a old d9 cart thatās purple? I havent, I can tell you if you run cbd through magsil itll turn purple because cbd quinone is made with a base + oxygen and cbd
well then i guess the multiple testing labs ive sent samples to are all wrong and theres cbd in my pure thcA haha i respectfully disagree but its all good to each their own

Not sure how you could be making purple thc a as I can literally take purple oxidized cbd and make it white through crystallization
Even the literature reports it as different colors
Thereās also a paper where they show the red layer on top of thc distillate is quinone
the thca doesnt turn purple until it is decarboxylated into D9, i do this under vacuum and use nitrogen to release vac, everything stays slightly yellow (have stored under vacuum for months) until it hits atmosphere, then it turns pink and purple. all the testing shows zero cbd detected. now if i do a run scrubbed with preform 6000 PH 2.5 it does not turn purple it oxidizes red. this is why it seems to me that the purple is a ph issue. this is all hydrocarbon based

Are you using any filtration media at all when you make the crude you crash into thc a?
Thereās also varying degrees of oxidation, you can have a full quinone, or a semi quinone on top or bottom of the ring
This is one reason why acetylations lighten color so much is because it actually can remove the top quinone on the ring which improves color
It would be interesting to try and acetylate your purple distillate, if it stayed purple it would have to be an impurity as ive taken red d9 and made it light yellow through just acetylation and distillation after
So this has been a topic iāve been doing an absolute shitload of research on recently and I do not believe the purple I experience to be THC quinones. I can reverse it and THC quinone seems like a 1 way street. If it is quinones they are ppm level. Do see quinones in old disty top layer though and I suspect if left to sit and not corrected the initial purple will eventually become quinones.

Was actually going to ask in a post above if he can remove it somehow as Ive heard of people being able to remediate it by backfilling with argon in a Vacuum chamber
I do believe any kind of color remediation affects color by removing the oxidation that causes the quinones (along with some impurities im sure)
I always reference my 1000 mg/g thc o, it was pure (by gcms which is ppb and 1000x more sensitive than hplc) and it was yellow so obviously something effects the color on the molecules
Hope youve been well btw!
