Need help identifying mystery deposit in roto

Ya sugars. @spdking is right if it dissolves in water its a dead giveaway

It’s not 100% determined yet. I’d love for others to chime in aswell, but it’s fairly likely it could be salts from the celite dissolving and then staying behind during evap. It doesn’t taste like salts though which is the main reason I’m not sure yet.

Edit: lol. The page hadn’t updated properly when I typed this, so I missed the other replies. But I’m thinking of running it through more t5 which (logically?) should remove water solubles.

When I showed Elliott my celite bag he pointed out that it looks like I got bait and switched on that bag cause it’s off white gray and it only says celite on it. So he said it likely has salts in it.

I’m trying to avoid heating it up so it doesn’t decarb, cause that pretty much destroys any possibility of making any of the products I’m trying to make. I know 200 is just under. I might give it a try, but sugars should be removed by t5. Just woke up, so it will be a couple of hours before I get to this. But I’ll refilter and keep you posted.

Since you have also noticed this, do you mind sharing what other media you use? Maybe we can find an overlapping occurrence to narrow it down?

Hey Renchi, sorry for the delayed response…was a long night. The only media we currently use is Carbon A and Silikate Pulver. When I use both Carbon A and Silica, I notice that I get varying degrees of the particulate showing up in roto flask as the solution become more condensed/concentrated. I originally thought that the silica was the issue as well, but after removing this variable I was still seeing a good amount of particulate crash out in solution on the rotovap. If I do not use any carbon, I have no issues whatsoever.

To me it seems to be the carbon. I have tried other carbons/charcoal powders as well with the same if not worse results in some cases. Occasionally it would turn the oil greenish and make pure oil very opaque to the point I could not recover it other than distillation.

We further performed a wash of the carbon itself with 190 proof Ethanol and had particulate crash out on the rotovap. Maybe test this out yourself and see if you can replicate the results I found.

Hope this helps you troubleshoot further. T5 will fix your issue however but still doesn’t explain whats occuring.

Well, damn, this definitely adds to the mystery. Lol.

I took the day off cause I needed to just say fuck it. Been online the entire time, hahahaha.

I’ll see if I can run some tests. Gonna filter it later today. I’m trying to see what happens when having left it for a day without any vac. I’m glad I am my own boss and can say fuck 9-5. Work whenever you feel like it.

I want to see if I can get a clean sample to deal with.

Sometimes you just need to reset! Enjoy the day and let me know what you find out. I would be interested to see if the results are similar.

One day I’ll be my own boss…hopefully at least haha

I haven’t seen much charring of sugars until over 280 farenheit (140 c).
If I had to guess I’d go with your mystery deposit being sugars as if they were salts I’d expect them to be salty, but the taste could be covered by whatever other residue sticks to them. Salts won’t char but stuff that’s stuck to them will so before testing by trying to burn them make sure to wash thoroughly with solvent.

Second this

Ok, so I ran it through some t5. It looks like the deposits disappeared, but that wax like substance got through. I’m thinking that’s phospholipids making it through cause I didn’t do the proper brine wash to remove it.

It totally dissolves in etho. I’m quite certain at this point that it isn’t any powders making their way through, so it must be something from the plant. So, I’m just going to adhere to proper protocol in the future and hope that this doesn’t occur again.

Well, it fucking happened again and there’s a kicker now. What if these deposits are actually water soluble pesticides? Cause the oil came back hot for tebuconazole and acequinocyl, but also had bifenthrin in it… I am now wondering if that is what’s been showing up, cause initially I thought it was powders slipping through the filter papers, but now I’m really not so sure anymore. Cause one of the things mentioned was a tingling sensation for up to 12 hours, which is exactly what I felt when I tasted it.

Thoughts?

Wipe it with a paper towel and solvent of choice and wring out the solution for testing

Yeah, you’re right. I have to do that.

Hey, did you ever find any cause/final solution here? We are having the same problem and are very perplexed. Also using Summit AC. Thanks

This is weird; it’s the same shit I see on my blasting dishes after resolving into ethanol and transferring to a beaker for freezing… I assumed it was fats n other impurities…

This is what I was thinking being water sol. But I wanted to read all of the replies before making my assumption.

acequinocyl might be caused by the acid they used to activate the carbon and wash away any ash. Are you getting side isomerisation?

" Specific grades of activated carbon are engineered to function in acidic chemical processes. Select activated carbons are acid washed to remove acid soluble ash in preparation for use in the acidic environments. Acids that are commonly treated are HCl, Phosphoric acid , and Sulfuric Acids ."

I found it happened more when using celite. I was able to remedy it by dissolving in etho or heptane and running it over a bed of t5. Alas i never got a clear answer to what it actually was. Also since it didn’t happen all the time it was even harder to figure out. Salts were mentioned as a possible culprit. That’s all i can say, unfortunately. I never sent it in for testing since we moved to other processes.

Edit:
I’m wondering if one could prewash the powders with water filter and then dry the powders out while activating in the oven to see if that could remove these deposits. Cause it could be residual acids as it burned my tongue when tasting it.

I just posted something about this, i think celite is probably the culprit. I think prewashing is the next step in ultra pure extracts using powders
