Pink Distillate Quick Fix?

[DrWHY420]

Hi,

I have some distillate that is slowly turning pink after it is heated up and exposed to air.

Is there a way to prevent this from happening? I would like to add something to the boiling flask in order to prevent this color change from occurring or is the only option better storage conditions?

Thanks

You might want to look at ur steps b4 u distilled, did it go thru any high or low ph bleaching powders?
Usually when u see pink or purple oxidation, its because of a ph imbalance in the oil

Yes, would adding citric acid or baking soda fix the problem in the boiling flask?

Citric Acid Degumming Tek

Workers use citric acid to “degum” distillate or crude resin intended for making distillate. There are several ways to employ it, and all require a bit of water to disassociate the acid… i.e. make it acidic by letting it ionize into H+ (actually H3O+ “hydronium” cations in water) and negatively charged citric (citrate) conjugate base anions. Before you begin working with any acid or base, you should measure the starting pH of your hydrated (water-containing) resin solution. To do this, use Hydr…

Degumming (Citric Acid + Enzymatic), Winterization, Saline Scrub Critique

Hi All, I have recently had extra time (a very rare occurrence), and it dawned upon me that I’d like to insert the entire playbook of remediation for my EtOH-extracted distillate. The process is as follows: Cold EtOH extraction (generally between -40 and -20C), cold bag-filtration 10um->5um->0.5um, solvent recovery, decarb, terpene strip, distillation. My intention is to take that first pass distillate and do the following: Water Degum - Add 10% neutral RO water (not brine) to 1st Pass Dis…

Pink THCa?

I believe it due to latent ph oxidation. Lower ph value

[DrWHY420]

This Tek is to complicated; I can’t use some of these solvents and don’t want to use water to scrub my oil and change pH. I’m looking to add something to the adsorbents or the boiling flask of my distillation system or in Ethanol during homogenization/winterization.

[DrWHY420]

Looking at my adsorbents, the problem is low pH.

Are you scrubbing it prior to distilling? Ive had good luck with adding baking soda as the last part of the scrub to neutralize it, worked great when water clear was all the rage.
