Removing THC from CBD oil?

I've made some oil from a high CBD oil plant, however I'm wanting to remove the THC completely so am wondering if any one would know how to do this using heat? Or perhaps someone has a method of converting the THC to CBN whilst keeping the CBD in tact?

Indeed it's said that CBD and delta-8 can be much harder to aromatize than delta-9, but who is wanting CBD with CBN in it? Is crystallization a viable method of removing a small amount of CBN from a large amount of CBD, or will CBN crystallize within CBD, or CBD within CBN, or do you get a mix of CBD and CBN crystals?

In my trials aromatizing the THC in hot CBD with Iodine, yes some of the CBD goes to CBN, but not as quickly as the THC goes to CBN.

Agreed that CBN in your CBD isn't great, but at least it then becomes a legal product.

Interesting, it wasn't iodine that I was thinking of when I wrote that and I'm not sure it would be a good choice. In that article there was purification by chromatography, but what happens if someone doesn't do this chromatography? Someone else gets sold iodocannabinoids? For bulk CBN from THC, considering the cost of iodine and the joy of trying to recover it from residues, it would not be surprising if sulfur was better in the right hands. Wouldn't crystallization be desired for THC remediation of CBD?

Figured I'd take advantage of this opportunity to ask a question.

Can you guys expand on that. Why is it not good to have CBN with CBD?
Does CBN lessen the medical benefits of CBD?
Should full spectrum extracts that contain CBN be avoided?

It gets grandma high. Intoxicating people is a problem when there intoxication laws.

Thank you. I thought it made you sleepy, didn't realize it got you high as well. Now I understand.

Chromatography might be the best way to accomplish this separation.
