Depending on how much water we’re talking about you could just wash it with 200 proof etoh in a rotovap and let the azeotrope do the work. That would get you where you need to go without adding anything else to you extract. The down side is that it takes a decent amount of EtOH. The azeotrope is 5% so for every liter of 200 proof you use you will remove 50ml of water.
Is this for a short path crude? If so I would recommend decarbing in general. I go straight to 140c for 2 to 2.5 hours with my crude before putting it in my SPD. It Cooks off the volatiles and makes the whole run easier and faster. As @Soxhlet said that will also boil off the water.
I usually only find minimal water but enough to cause issues.
most recent finding was when I was loading my ethanol:cannabinoid solution in the rotovap - towards the end, i started noticing a milky swirl which i’m only currently assuming is some water.
most of my crude goes through my wiped film so definitely agree with your method. But I’m thinking for future instances when I make a product like ‘sauce’ that would not require a decarb - what would be the best method to remove the water?
You should also be looking for the source of the water. If it’s coming in durring the extraction then you’re not running cold enough. Sometimes it just happens but if this is a consistent thing for you I would go over your extraction SOP.
I’m not trying to figure out how/why the water got in there or even how to prevent it. I understand what happened and whats been done is done - the water is there.
@TheLostBiologist recommended flushing it with 200proof etoh
and you both have recommended to decarb or not to get it in there in the first place.
but hopefully you can see how the latter two suggestions dont really answer/address my question
Best way for good extracts is avoid h20 pickup in extraction.These are all measures we go through great lengths to limit.
When you posed the question “water in my crude” Im sure everyone here assumed you were making distillate. The word “crude” isn’t used when reffering to the extraction that creates “sauce”.
Try rotovapping the extract with etoh as @TheLostBiologist suggested. You may be able to dessicate it, or pick it up with nonpolar solvent in a sep funnel.
Sorry if i came off like a dick, my mild retdation makes me this way… Just ask @Indofab about the welding rod in a dremel argument we had last fri… I hope that fucker knows Im right! lol!
not at all - I have similar tendencies and usually also have to explain myself to new folk. Although we’ve never physically met(unless you were at the seminar last night) , I’ve seen enough of your posts/responses on here to know you’re not a dick
Its been a long week for me between MJbizcon and all the events revolving around the conference so I know some of the things I’m saying doesnt make sense at this point.
And on that note…I’ve just decided this is the last thing I’m doing before I close down my lab and shut my brain off.
If you don’t mind terp removal in the process, you can try an LL extraction with a non-polar solvent and methanol. At least that’s the route I’m going to go after finding out my ethanol had about 2% more water in it than I thought after my extraction… Though I hadn’t thought about using 200-proof to suck up that extra water. Sounds like a much more straight-forward approach for small amounts of water contamination.
I run Etoh and was doing some R&D with some fresh frozen…
Did a first wash at cryo temps before a secondary wash at room temp to remove any target compounds left behind. I know the second wash pulled a lot of the water from the frozen material and was just looking to see if anyone was utilizing a method that could remove the water earlier in the process to alleviate the painfully long winterization times. so far it looks like i’ll be cold filtering all day
