OK, maybe I can help a little
I've dabbled a time or two with the iso thing. In fact, lol the first time was back in the 70's with a cool little device called the ISO2 by Thai Power Inc.
What it is, is you extract the oil from the plant
clean it up the best you can, I.E. "winterization" even carbon filtering if you like
weigh the extracted oil
redisolve oil in at least 91% alcohol. I like everclear
add 5 drops concentrated sulphuric acid for each gram of oil
now reflux for about an hour
neutralize acid with baking soda, be sure to use over kill
filter out undisolved solids/baking soda
now & this is important, mix about a third of the spent cannabis you extracted back into the dissolved, isomerized oil and slowly evaporate alcohol from weed.
make sure it is DRY then pack loosly into a good sealing jar, add warm distilled h2o to about 2/3 full, close up & shake
after about 5min. pour through coffee filter and repeat 2 more times
NOW we get the good stuff, dry the weed out again thouroughly
now extract the iso'd & purified/washed oil back out of the weed with everclear
Now you have isomerized hash oil suitable for turning into THC Acetate.
From MY experiances, a person needs to have a pretty healthy supply of weed to really be worth messing with, as a lot is lost filtering and such.
If you have to buy from a dispensary or whatever at the street prices, my suggestion is don't waste your money.
If you have plenty of product to experiment with, go for it, it's a fun way to break the routine up a little
I hope this help clarify things a little
detailed instructions, step by step are available on the web in many places
Hey I've been working on this experiment for a while. Just a few things left to buy. But I think this is what your looking for.
Decarboxylate, wrap plant material in foil and bake at 220Â°F for 25 minutes.(Do not burn material)
Add 100mL of deionized H2O to a beaker for the first gram of material and add an additional 20mL of deionized H2O for every additional gram of material.
Heat the beaker and its contents between 55Â° and 100Â°C for 15 minutes. (do not allow mixture to boil)
Remove plant material and dry thoroughly. And grind once dry.
Place ground material into a clean beaker and add C3H8O and heat between 60Â°C and 65Â°C for 20 to 60 minutes. Use about 20 mL of C3H8O for every 2 g of material.
Filter out remaining organic material with gravity filtration. (use grade 1 filters)
Filter out impure colors with norit charcoal.
After allowing solution to cool to room temperature place into an ice bath or freezer/fridge. Filter crystallized solution via vacuum filtration. Save filtrate as it can be used in conjunction with step five. Make sure crystallize THC is thoroughly dried before storing it in an airtight container.
if you want to smoke 99.6%THC then something called budder is the answer. this is actually a marijuana extract that is made by whipping in air and freezing isomerizied hash oil. isomerization is an additional chemical step that converts the delta-9 THC to 6-THC activating a lot of the normally non-active cannabinoids. people who have smoked budder say they have never been so high in their life. the high is said to be mildly psychedelic and very uplifting. very euphoric and cerebral with no couchlock. you could probably get about forty hits from one gram. one gram can cost as much as $140.00. if you want your brain in the stratosphere budder is what you want to smoke.
I know this is an old thread but I just have to comment. First let me say that I make bho and have everything needed to make a quality product. I vacuum purge and keep constant temperatures. I have had it tested and it never hits 99.6% not even close. I have hit the 80s though. So my question is:
How is 99.6% possible ?and I would love to see proof..
