Beautiful work @Montroller

Looks great same color we are pulling tried doing what you said but still pulling red
You might be able to clear it up with AC in the flask

I doubt that you are producing d8.
D8 should be nearly colorfree.
Those high temps with ptsa will produce some bad stuff. Very harsh conditions for cannabinoids
Even if you leave pTSA and CBD at RT for a longer time, it will turn into a brown slurry and distill over red and orange.
Do you know what temp should be used and for how long
We only chase after high d9 conversion.
High d8 runs are more like an accident.
Happened pretty often, but I can’t give you exact numbers.
If you scale the method from this paper, you should get high d8. Your solution will turn blood red.
Its a waste of ptsa and I give no guarantee, as I only made one 10g batch.
Others here know it a lot better, but keeping the temp below 40°C will solve your problem with red color.

So room temp reaction rather than refluxing at higher temp

@Montroller You say that you let it reflux in the head for an hour and then run through the wiper. I haven’t been able to get the red out at all through my RFD rolled film machine, so I have resorted to tossing the oil into my SPD’s after conversion and LLE’s and pulling the red fraction out and then stop the SPD and run the remaining oil through the roller. Does running in a reflux work so that you aren’t left with a red fraction?
What are the rest of you doing to get rid of the red through a wiper / roller?
This is what I get just through the roller…
This is what I get out of the roller after I toss it in the SPD and pull out the red fraction…
I been playing with parameters and cant seem to get the red to just pull to the discharge area. Any advice would be great, thx guys

You are experiencing the same exact problems as me. I was using a shitty chinese wiped film and couldn’t get my vac tight enough to pull the heads but we just upgraded to a delta RFD and I’m gunna try to separate a bunch of heads next week. I am probably going to run it at 155c jacket and 145c inner condenser then slowly ramp up both until it starts distilling cannabinoids then drop down a degree or 2 and see if that works.
That last pic is beautiful btw
@BrownGuy420 what solvent are you using? Certain hydros won’t hold onto the reds through certain bentos. Might be worth a pass before and/or after LLE

I’m using heptane, so what you are saying is that possibly my solvent is holding on to the red pigment more? I ran through Bentonite but it seemed like the Red stayed in the oil.

Let me know how it goes through the RFD. I have the same machine and trying to dial in the parameters, maybe we can help one another.

There’s no way you’re neutralizing all the acid if you’re getting that color off of isolate

I’m not sure it’s holding onto the red “more” as I don’t know what would be less??
Each solvent is unique in what they like to take to the party and how much they can take to the party. Heptane is a personal favorite of mine for only allowing a pretty solid VIP through.
That being said, one of your solvents is letting everyone in. HINT HINT

I use heptane and you’ve seen the color I pull
Solvent selection doesn’t matter, yes certain solvents can cause color change more then others its not something that’s not correctable though

Heptane
This was from distillate too not isolate
The color on that liter definitely makes me feel like the pH isn’t correct
Looks pink to me

Those liters we’re off a SPD though right? I can pull a red fraction off the top with SPD and pull that same color. The Roller doesn’t pull the fraction off so I either need to figure out how to cut the color to the discharge (which I’m positive it will) or filter through media to pull the red. The acid is definitely neutralized and I do feel the red could have came back after filtering through media because I feel the media whacked the ph so maybe an LLE after filtration to level PH back out
Those were off an spd, I can show you better colored liters off a wiper
Even on spd I don’t get a red fraction
What media did you use to filter?
What acid are you using? Ptsa?
Are you neutralizing with sodium bicarb?
Whats your evaporator and condenser temp?
Are you cleaning the wiper good after each run?
I’ve found most ppls problems with color on a wiper come from letting tails co distill which dirtys the discharge side and can make proper color impossible to achieve without a cleaning

How does your solution have a ph to change???
Edit: The problem is water.
