Synthesis of ghb (free acid) from gbl View Thread Reply Hide Matilda Chommlekog - Tue, 18 Jul 2017 22:06:27 EST 1reNg8pO No.78749 File: 1500429987701.jpg -(42696B / 41.70KB, 500x345) Thumbnail displayed, click image for full size. Hey/chem/I recently came across some lab grade gbl (gammy-butyrolactone) which is the precursor to GHB. I've got a few questions because I've never find GH and I'm having a hard time finding some info from chemists who know what they're doing.Firstly, I wanted to make GH in its free acid firm, rather than the common sodium butyrate salt. What I want to know are whether its fine to take it in free acid form. I think the pka is about 4, so it shouldn't be too sour if diluted in water, but taking it in free acid produces the same effects right? I assume that taking the sodium salt would Judy result in it finding in the acidity of the stomach anyways, I just would prefer to not have to eat a bunch of salt on the side.Also, did I do something wrong in my procedure?I started with about 10g gbl weighed analytically, and calculated the moles for sodium hydroxide which was between 6-7g, but I put in some excess to try to push the reaction forward. I then added a bit of water, roughly 20mL in a round bottom flask, added the hydroxide and then the gbl. After a few minutes, I capped the flask and put it in an oil baths at 70 celcius. After 2-3 hours, I added a bit of hydroxide to make sure the reaction was basic and he GH would be in its salt form, then I washed the solution with ether 3x to get rid of any remaining unreacted gbl. I took the aqueous layer and added HCl from a 1M solution until the pH was about 2-3, low enough for the gh to be in its acid form. I think the problem is here, because I couldn't find concentrated acid so I ended up adding a lot of water on the side..Then my last step was to extract the ghb from the autos later with ether. I did this about 3x, combined the etherI'm layers, and evaporated off the ether. I was left with 2g when theoretical yield should have been about 12g.Do you think that because I ended up using so much water, my remaining gh is in the aqueous solution? I know theree acid is readily soluble in both water and ether, so I'm wondering if this is my problem. Also, how can I test the solution to show I have ghb with no gbl? I don't want to use the NMR spectrometer just in case somebody ends up seeing the spectrum and asking questions 1 posts omitted.

There's probably more in there. Also try adding some salt (NaCl) to the water to lower the solubility of the GHB in it.You can tell if there's any GHL in it by taste. GHL supposedly tastes awful whereas GHB is tasteless. >> press !XIxc6BpKnU - Sat, 22 Jul 2017 18:28:22 EST PJ0/E4z+ No.78753 Reply >>78751ghb has a distinct taste too, it just isnt as fucking horrible as gblsomewhere between gasoline, coconut and soapOP have you considered to simply mix the gbl with a sodium carbonate solution to get a ready to use sodium ghb solution.obviously youd have take in more volume but it always worked for, although getting too much sodium isnt too healthy and the sodium salt gave me just as much diarhea as gbl.since the sodium salt is hygroscopic anyways youd have to hustle to keep it dryhttps://www.erowid.org/archive/rhodium/chemistry/ghb.html >> Cyril Sunnertot - Mon, 24 Jul 2017 16:41:05 EST CwYciqLe No.78754 Reply Thanks for the replies everyone. I found a paper and read that ghb is rarely found in its free acid form as it readily converts back to GBL. This back conversion happens even more easily in acidic conditions, which I used to try to protonate the free acid. I will extract as much of what is most likely gbl now from my aqueous solution using salt to push it to the organic layer, evaporate any ether and water left over and mix the gbl back with a small excess of sodium hydroxide. I'll calculate it so that once all the gbl had reacted with the sodium hydroxide in a 1:1 stoichiometric fashion, that the pH will be about 8.5 at the end in a small precculated volume so the ghb doesn't convert back to gbl

Diamorphine is highly aromatic and you're more likely to get a hit on a non polar aromatic solvent. Plus acid base is typically used to free chemicals from plant matter. Since garlic doesn't naturally contain morphine, or any forms of it, I would think that the morphine is mixed in rather than bonded with the garlic in any way.I would try soaking the material in xylene for an hour, placing the mixture in a cheese cloth, and squeezing the liquid into a separate container, preferably glass since some plastics are soluble in aromatic/non-polar solvents. Then chill the strained liquid in a freezer and scrape up the solids that come out. Use the liquid left over to soak the garlic again for a second and third extraction.More than likely, the solids that appear after freezing will be dirty with garlic compounds as well, but it's the first step in the right direction. after that, just purify it. >> George Depperfit - Sat, 01 Jul 2017 11:20:59 EST 4tmtdVyg No.78718 Reply Oh wow, this thread is old as fuckOP, you dead?

I'm currently using kratom to isolate its alkaloids via oxidation > extraction and am starting to get concerned of possible byproducts of my reaction. I am not using lab grade glassware for the first steps involving oxidation with H2O2.My main concern, is it possible for free radicals to form and possible trace amounts of metals in my final product. I'm basically soaking the kratom in H2O2 and agitating on low heat with small amounts of citric acid added, then that is continued until the material is almost completely dry where I'm assuming the leftover liquid is water since the H2O2 oxidizes the mitragynine and 7-OHM into mitragynine pseudoindoxyl. Can anyone experienced in organic chemistry help me out with this? We only use cold water for the extraction of the oxidized kratom material so that isn't much of a concern as much as using metal pots and pans during the actual oxidation process. Should I be concerned of consuming free radicals once fully evaporated? Are there any possible byproducts that can form from doing this?Thanks a ton and excuse my ignorance in chemistry, I don't know shit besides what I learned in highschool and my current research onto this topic. The pic attached is the final product after filtration of the initial oxidized material through cold water into 5 then 1 micron filters then finally evaporated at low heat. 1 posts omitted.

It takes a few minutes of google and there is plenty on the oxidation of 7-ohm into mitragynine psuedoindoxyl. I'll post it tomorrow when I get a chance though.thanks for that reassurance, like I said I'm ignorant to this in all aspects and this is a learning experience for me so bare with me. We did though, I got the pH down to 4. As far as the difference between just soaking in water, we've tested it. It does not come out like this at all. The peroxide makes a giant difference. I do understand h2o2 wont oxidize much until the pH is lowered a decent amount. >> Hunter S.

You have no idea how much oxidant to add because there are thousands of different compounds in the mix all with different oxidation potentials.Also the paper you posted is an overview of a semisynthesis of mitragynine pseudoindoxyl from something other than mitragynine. I still can't find anything on chemically converting one to the other. Everything i've found so far involves bacterial or fungal metabolism to affect the rearrangement. The way I see it, it is very unlikely that you will be able to produce a sizable amount of pseudoindoxyl with household oxidants. I am kind of curious about this now though so I am still searching.

Pretty much any phenol without other more lablie reactive sites can be converted to an allylbenzene (like safrole) via condensation with allyl halide and subsequent aromatic Claisen rearrangement of the allyl phenol ether. From there it's known chemistry to get to an amphetamine derivative. pic related is delta-tocopherol, a form of vitamin E, and it's resulting amphetmaine derivative, which is strikingly similar to the 2C-x's and DOx's. There are literally thousands of easily obtainable phenol-derivatives out there with possibly psychoactive derivative amphetamines. Why has there not been more exploration into this chemical space?

At least in chemistry there is an internal logic to it once you get the basics down, but with molecular pathways it's almost senseless memorization with having to know all the different (often randomly named) parts and how they interact with each other.
