Sulfuric Acid

One gram of CBD is dissolved in 10ml 200 proof ethanol.
1 drop of concentrated sulfuric acid is added to the mixture.
The mixture is refluxed (gently boiled while collecting the vapors) for 2 hours.
The solution is then added to an equal volume of cold water containing 1/4 tsp. of baking soda.
10 ml of hexane is added to the solution, gently mixed, and allowed to separate into layers.
The top layer, which has turned to a beautiful cherry red, is siphoned off. This is repeated several times until the solution is exhausted.
Evaporation of the hexane yields the product - a very bright, very pretty, thin red oil.
The final traces of hexane can be removed in a vacuum oven.

"Dissolve the hash oil in absolute ethanol or pure methanol in the ratio of one gram extract to ten grams solvent. There must be no water in this solution, as the next step is the addition of one drop of 100% sulfuric acid per gram of extract. Add the acid slowly, drop by drop, stirring slowly and completely, with a long glass stirring rod. Place a
Pyrex pot containing the extract-alcohol-acid solution into the refluxing apparatus and reflux for two hours. The acid will not
evaporate and will remain in the Pyrex pot. Allow to cool. Take the cooled solution, pour with an equal volume of water and 1/2 volume of petroleum ether into the ether-extraction apparatus (separation funnel).

Allow to settle, and drain the ether extract layer. This leaves an ether-extract-acid mix from which the acid must be purged. To
accomplish this, pour the ether-extract-solution into four volumes of 5% sodium bicarbonate solution (1 gram bicarb. in 20 grams of water). This
will neutralize the acid, releasing CO2 and leaving a solution of sodium sulphate. Allow this to settle into layers, then drain the
ether-extract layer. Mix the ether-extract solution with an equal volume of pure water and let it separate. Drain off the ether-extract layer. Evaporate the ether and what remains is hash oil in which all of the cannabinoids have been converted into THC."


3g of CBD
100ml Isopropyl Alcohol
1gram of table salt
4 drops of 98% sulfuric acid.

table salt is put in flask with alcohol then the sulfuric acid is dripped in and flask swirled to mix.
flask was then heated to a boil and when boiling CBD is added and
condenser is placed on top of flask.
solution was refluxed unstired for exactly 2 hours.

when 2 hours was up I poured the mixture into 400ml of cold water and then extracted
with 70ml heptane
then again with 30ml heptane.

both heptane extracts where put together and shaken with 200ml of saturated bicarb solution
and then with plain tap water.

heptane was removed at atmospheric pressure I did not use any inert gas beds or protection

there where traces of water still in my ipa

there is more salt than h2so4 so you will get a nice moon rock of na2so4 with some skittles of
crystal salt to prove you didn’t add to much sulfuric :slight_smile:

pay attention to bring to temp before adding CBD.

I am making HCl in a measured amount from the table salt and sulfuric acid insitue.

I want it converted before I add my CBD.

I also want to know the time of the reaction rather than how long it took for it to start and then how
long it ran.
that start is an unknown as your conditions are changing.

then I dump it into cold water.

done reaction finished when I choose not when the environment around me the thickness of my
flask how cold my fridge is etc.

its diluted and cold now so no more reacting.

I have control of the exact start of reaction and then the exact end.

now I can start playing with ratios as I have a way to measure reaction time.

I will write this up properly soon when I get some analysis on it.

It wont be pure delta 9 no way but its clean and quite strong.

much much stronger than the phosphoric acid alcohol isomerization in adams 1940’s paper.

from what I have read it is to be expected in the 50% 60% range.

the oil was so near clear it was not runny. 1 gram stayed an oil after being left in an open bowl
for two days.
