winterizing

[Hammerhead]

I need some help with the process. I took about 28g of BHO and dissolved it into 95% alcohol(190p ever clear) Frozen for 48hrs give or take. I could see the waxes on the bottom but when I tried to filter the waxes from the Liquid it did not work very well. What is the best way to separate the waxes from the good stuff.

after 48 hr frozen i would have thought wax would have been solid or set atleast

I have yet to try it but thought it was as simple as pouring the oil enriched alcohol through an unbleached coffee filter... then let the alcohol evap off... I wonder what else needs to be done?

curious to find out more before I try it now

 

[Hammerhead]

that's what I did. I could see the separation there was a white slurry on the bottom and the oil floating on top. I will try a longer freeze time? When I tipped the jar to pour out the oil it all seemed to mix back together.

did u do the filtration in freezer, if not fats melt back into the mix, I do mine outside , prob only advantage to living in such a cold ass place ,....

As teemu said, filtration should ideally be done while refrigerated, or speedily with a vacuum.

I was fooling the winterizing process for BHO. Mixed purged bho into 190P Alcohol for 48 hrs. Put 73um filter over he jar and poured the contents into another jar. Very little to Nothing would pour through. Should I dilute it with more 190p???

 

[teemu shalanie]

takes a long time to filter through , if u can spin it upside down in jar to drain while it is in freezer i give it lil swish'd round to help the process

I was going to leave it in the freezer until the 42um bag gets here.. I will have to get patient with it. Good things come to those that wait

Im still a bit cunfussed.. There are 2 layers forming that is visable the top looks like liquid oil. The bottom looks like resin? large particels... is all of that heaver stuff the wax ??

 

[Infinitesimal]

have you watched any You Tube vids... I am a bit of an audio visual learner so it helps me out... though some people do on know what they are doing at all there are a few good ones out there

 

[Hammerhead]

yes im doing it right. It's just a slow process. They say that the stuff floating in the jar is the paraffin waxes. I will finish with the directions and see what I get.

i use a ghetto seperatory funnel (plastic baggie). there is some loss of alcohol, but i manage to reclaim it by saving until there is enough to seperate it.
you can discard the whiteish lipids that coagulate into the bottom.

it's gooooood medicine.

I suggest paper lab filter for the purpose, i suspect waxes arent solified enough to be stopped by a bubblebag either 42 or 73 microns are way too big.
If you struggle to find a lab filter and dont want to wait a web order just use a american coffee filter...you can find em everywhere also in supermarkets sometimes.
Another thing to take in account is that you need really cold temperatures to see a distinct separation of the lipids, at higher temps the dissolution is partial. In my experience with a -20°c freeze waxes are not fully solid. In scientific papers winterization is done at -35°c with lab freezers.
Another important thing is to use the correct amount of alcohol, 28g of bho is not that little, maybe jump or gunnaknow have something to say on this, i dont know the ideal rateo but when i do it i use say 2g of bho and dissolve it in a glass of ethanol wich is about 200ml. It works pretty fine.

 

[Hammerhead]

All of the Alcohol will be purged off. I will get some coffee filters.

 

[Hammerhead]

OK I got it filtered. That was not such an easy task. What I did was waited until all of the waxes had settled on the bottom. I poured off as much of the oil mix as I could without getting any of the wax . I then used another jar with a coffee filler on it to screen the rest. This was very difficult. The wax oil mixure would not go through the filter at all ver y hard to get it all though. I now have a jar 3/4 full in the freezer to see if there are any waxes I missed.

Strange that filtering has caused difficulties.
Maybe the solution was too thick?
In my opinion, to dissolve 28g required 420-1400 ml.
How much ethanol you use?

15ml ever clear to 1 gram RAW BHO
this was 900ml and 60 grams

Hey RulaTone, that's a good point, 42 µm and 73 µm may not be fine enough to catch the very smallest particles. Coffee filter papers tend to range from 10 to 30 µm and work well. Whatman #1 lab grade filters are rated at 11 µm, so they're similar to the best quality coffee filter papers. Anything finer isn't necessary for these purposes.

The temperature is important, as is the duration of refrigeration. The temperature doesn't need to be lower than -20°C for sufficient separation but a colder temperature will increase the level of separation aswel as the rate of separation. As the solution cools it reaches the cloud point or wax appearance temperature (WAT), which is the point at which the wax crystals first appear. If the temperature remains at this point, the crystals will slowly agglomerate due to attractive forces but may not accumulate enough mass to precipitate to the bottom quickly. If the temperature of the solution continues to drop, more waxes crystallize out and interlock with those already present. The further the temperature drops, the larger the agglomerates become.

The agglomerates will have less mass if chilled to -20°C rather than say -35°C, although they are still typically atleast 50-250 µm in diameter and can be filtered out with lab or coffee filter paper. Of the various scientific papers that I have read, the temperatures that were used ranged anywhere between -10°C and -40°C but were most typically between -25°C and -30°C. As you suggested, the colder the better within reason. Although -20°C will suffice for butane extractions of cannabis, which are often less waxy than many concretes. Obviously, we all know that chilling the alcohol is just an additional refinement and not absolutely necessary. Jump was routinely redissolving his BHO in ethanol and then filtering, quite some time before we discussed additional chilling and his specimens were some of the best that the community had ever seen. It's good talking with someone interested in the technical side of things.

I used approx 500ml..Its all good now I just checked the jar does not have anything in it that I can see.. Now for the purge. I have a hot plate that I will put the Pyrex dish with hot water in keep it warm 115f put the jar in let it sit until its purged.


Anyone got any other ideas??

 

[Hammerhead]

OK guys I have a pint mason jar thats 3/4 full. What would be the most efficient way to purge off all the Alcohol...I tried to use 60c water but that would take days to finish
