Making Wax w Propane

[oilmkr420]

Propane is the biz. Just found out power 7 isn't just refined 7 times, but a mixture of n-butane, ISO-butane, and propane. It's impressive and led me to try propane alone and it makes a much prettier extract than n- butane by far. It gives a higher selectivity than butane, and is much cleaner results in spite of the mercaps used as odorants. The taste is a bit off, but the extract isn't nasty, just different as every solvent leaves an inherit taste w all falling short of ethanol. The methods are easy and runs are very inexpensive when compared to the cost of tane.

Perhaps it's due to propane being a bigger molecule than butane.

Ok, now go get some cleaner propane... it is available.

Mmmmmmm, just the opposite.

Propane weighs 44.1 grams per mol, and butane weighs 58.1 grams per mol.

 

[oilmkr420]

right, higher selectivity, less yield, better job than butane.

Vapor pressure is perhaps the reason. I hit the extract w n butane, a can of king, and what it pulled out was not at all yellow like propane was the first time. It was way dark after the butane was introduced into the extract.

 

[oilmkr420]

Yup the breakdown is like this,
Isobutane 31psig
n-butane 16psig
propane 110psig
Thats what liquide air rated the service pressure of specialty gases from their cylinders. So its most probably vapor pressure the reason it works so well.

The first was propane extracted. Pictured above is the second time it was extracted w n-butane.

View attachment 3321454 The first was propane extracted. Pictured above is the second time it was extracted w n-butane.

The second wash always comes out darker ime. Try butane first and the propane...

R-290 is what you want. FD has a source he's tested.

If closed loop and can distill your solvent then go for it. Problem is most propane has mercaptans and excess machine oil from the canning.

Seriously though, it does appear you have a lot of plant material in the final. Look with a microscope. You using good unbleached coffee filters or the crappy white ones?

Here are some results from 50/50% with n-Butane.

Snaps is right, using propane that smells is a bad idea



Most depensiries use research grade propane, no sulfer smell

If they do use pane it's a mix of pane and tane. The butane in a closed loop system is distilled, cleaned of anylubricants

Try winterizing with unbleached coffe filters and alcohol i

Just winterized a batch that waxed up on me after being a. Pull and snap, turned into clear yellow shatter gold

What is the difference between bleached filters and brown filters. Does the bleaching affect production, flavor, smell, or effacacy? How much of a difference? Can most people tell the difference in a blind test?

Fritted disc funnels are better. <0.2 micron is the biz and can filter out activated charcoal where coffee filters can not.

Propane hits wax, butane does not. Winterizing is a desperate attempt to filter out clumps of waxy substrate through cold filtration but butane needs no winterizing, just smack it w hot acetone and just a couple drops to a small splash then vape off the acetone w hot plate vacuum oven whatever. It purges residual butane w ease and no product loss.

That looks way under purged gray wolf. Try acetone and watch it clear up all those trapped residues of propane and butane. End product should look like this.

The unbleached have smaller pores and thus are better at preventing fine plant matter from getting through.

But not going to filter out activated charcoal for decoloraztion for hot Gravity filtration. Besides replacing them every time is a waste.

Why would you need activated charcoal? Time spent cleaning a fritted funnel is also time and solvent wasted. Coffee filters are cheap and therefore disposable.

When blasting, if you filter the plant material during the extraction, using adequate filtration you shouldn't see any green to discolor your oil with particulate. Any non particulate chlorophyll in solution would indicate a warm extraction.

Uhm ok? I use butane, and vac purge w/ heat, then winterize or not depends.

I would never use acetone
