Purging Winterized BHO

Whats up C & E,

so i went ahead and starting the winterizing process. This is my first time. I only was able to get 91% ISO and wondering if anyone had any advice on how to purge. I read that because i used 91% when i go to thin film evap, room temp, with fan, that it is possible for a slick to form on top of the oil that is essentially going to trap the water and making fully purging difficult.

Does anyone have an insight here or a suggestion for a specific method. Ive done lots of researching on here, just not tons of info about running 91% so i was hoping for some guidance.

Also does anyone have an opinion whether you need to wait 24 or 48 hours before final strain and evap?? see lots of people just going 24, wondering if there is a specific reason to push to 48?

Thanks in advance......

Most of us here use etoh for winterizing. Im sure someone here can answer it for you tho.

Treat iso and everclear the same.....also treat 99% and 91 the same
I like winterizing in iso when I run a non polar solvent..its just so cheap
No it won't work quite as good as ethanol

i will post pics of finished result, Thanks Quizo!

I prefer 190 proof ethanol for winterization, because it is more polar and does a better job.

Evaporation with a fan can pull moisture from the atmosphere and leave you with a beige pool of mostly water, with some alcohol. You can freeze that and pour off the water, before using heat to drive off the rest.

We continued to get precipitation up to about 48 hours at 0F. We can do it in an hour at -70C.

Hey FD, I was wondering. I heard with ISO you can "drown out" the remaining water with a salt method. Basically where you add the salt, shake vigorisly, let chill for a bit and then syphon the alchohol and the water would be on the bottom (in theory). Would this work also with Everclear? I can get 151 everclear all day (not literally just in case..) and I rather not get 190 shipped because of cost. Could I do the salt drown out with Everclear?

Good question, and so I sent to Joe, our biotechnologist, for comment and will relay his response.

Thanks for asking fd!

From Joe:

You can use Dri-rite powder or pellets. Just add (stirring) until the dri-rite stops clumping. Filter out and dry in the oven for re-use.

That's pretty damn incredible to hear, can't wait to try this! First gotta get the dri-right pellets! Thanks again fd!

wow guys where one some really getting down and gritty with this one . Can I ask what a polar solvent is? Sorry to ask.

Will sun purge take out all the alcohol?

You can dry your solvent prewash using dried epsom salt. Dry the epsom salt in oven, mix with solvent and filter the water laden salt out.

In simple terms, non-polar solvents are water-immiscible, polar solvents are miscible with water.

finaly i got mig and qwiso in close range.
I've had this webpage up all week and I've just been looking over every value of all the solvents and researching the definitions of the terms.
I'm hoping to find things that can actualy point to why, because there's so many unexplained phenomenon in oil. When i hear I like to use a higher mix of iso butane on older material on a radio show, my mind goes buzzing on if such a statement is lucky dirty sock theory or is there some math to this that the guy has stumbled on.

Anyways my question is, under Molecular surface area they give a number from low to high.
Solvent accessible surface area:
What I noticed and started to correlate to things I've herd people say is, the higher the number the better solvent per ml used. " granted better" is experiment better, there's nothing better about adding a mutagen this is math im after. The human needs for extraction come later, like this human is afraid of flamables.

http://www.chemicalize.org/structure/#!mol=n-butane&source=calculate
http://www.chemicalize.org/structure/#!mol=hexane&source=fp
http://www.chemicalize.org/structure/#!mol=propane&source=fp
http://www.chemicalize.org/structure/#!mol=iso-butane&source=fp

Qwiso I followed that number with things you've said and it lead to what everyone says gives a prestine extract if it wern't so expensive or difficult to get in there region. Hexane.......
N-butane 154.37
Iso-butane 153.43
cp-propane 123.83
hexane 215.61

There were other category's like mass where I could see a clear doubling in the weight of hexane in comparison to butane or the even lighter propane. So trends in choices start to explain themselves in a logical way.
The definition of Solvent accessible surface area is the surface area of a biomolecule that is accessible to a solvent.
I'm having trouble reversing the statement to indicate how much surface area does a solvent have to grab at my trichomes for instance. I've been on the ml to weight level, i've never looked at it from a this solvent has twice as many hands as that solvent. I can take those numbers and start to do real math on cost because I don't think most people want to look at if their choices from day one lead to efficiency or not.

So is that surface area rating of any strong meaning? if you did want to try to develop a mathematical formula for for extractions?
Mig you seem to be the master of the Curve's, i don't know where you get them all. Does any of the data on that webpage give a complete enough view a solvent to the point where it can corroborate all of the wonderful anecdote's we get from people or jaw dropping facts we get from your charts?

The chart on how cold and how long could you extract to get everything is awesome, if i can create a chart for propane let's say by shifting the value's that truly make up why butane had to be so cold or stay so long. I can do the same experiment with hexane possible just as cold but for half as long, and have it not be some "hunch" but based off a real value of a molecule that I can multiply against another.

Think I might try the Rock salt method on the 151. Thanks again Qwiz for the links.

Hey qw,
I was wondering if you can help me out by explaining what the process is exactly? I have a 750ml of Everclear ~75% alcohol. How much rock salt would I add? Once added,I just stir the rocks/alcohol? Does the salt not break or anything? Also, will the liquid now be salty..?


Fyi, clear out your inbox lol

http://m.instructables.com/id/How-to-Salt-Out/
You do like that...just keep dissolving salt in till it all sinks to the bottom excess salt just sinks..yes a small amount of salt will be absorbed into the alcohol. Which is why its not the preferred method but. I've done it and I think a few have done it with iso around here too..
But you shake shake and let the layers separate just like in the link and siphon away...cleared it

Saybian ..don't worry about solvent accessible surface area....and I always prefer the branched chain isobutane

I wonder if it would affect the extract in that case..? Perhaps the dri-rite is easier to gather and not dissolve into the alcohol..
