Since i own a centrifuge(or build one out of old drone motor) i'll give it a try. To come back to the actuall topic and Answer my own question. Yes, cocain can be reoxidized for purification. See https://www.emcdda.europa.eu/publications/eu-drug-markets/cocaine/production_en#figure1 Just...

Can you explain how does soubility work ? I can find sources stating 2.7 - 3.2 ml ethanol can dissolve one gram. If i try with up to 4 ml per g. The stuff remaining in filter still tests positiv with morris reagent. My theory is there is some kind of sugar mixed in. The sugar can dissolve in...

Wow, thanks for the friendly and respectful response. I'm sure we can find better ways to purify. Was the water recrystalisation that you meaned with "I can give you a scheme that will actually leave practically no trace of adulterant, " ? If I look in my notebook i tried it already 6 times...

These and some more are all cleanings teks you can find on the internet. But you right i've no idea what happen on molecular level. I'm not a chemist. But i realy like learing alll these things and get rewarded with good blow. Actually i spend more money on eqipment and chemicals than i want to...

Okay, i'm unsure about the Ehrlich reagent. It is not supposed to become green... The other give mixed signals.

Hi, currently i'm struggling with finding a decent source. Even after 1.Aceton Wash 2.Ethanol Recrystallisation (i speed up the filtration with vaccum could that be a problem?) 3.Convert to Base 4. Hexan L-L Wash 5. Convert to HCL Again 6. Second Ethanol wash I end up with at least 4 very...

So, there nothing i can do? Of course i will find a different source because of this, but nobody likes chemical challenges? What would happen if i added very small drops of solvent to a great mass of powder mix and pipette on a surface? The stuff solved by solvent should change from drop to...

More than 1 gram

Hi, i got batch of cocaine which is unfortunately cut with Meth. The Simons color test confirmed that. Since both are very souble to water the cold water method doesn't work here. I tried to find a solvent but both seems to be identical. This is what i found for information. Cocaine...

We had the some topic here. I solved it by putting it in acetone to make solid again.

Sad Story :( I'm thinking about designing some parts that can be 3D-Printed for making A/B easier. It's look like you already did the some of the experiments i'm currently doing. What cocain purify teks can you recommend ?

I bought a frit buchner not so long ago. Purifing stuff realy takes people into buy glassware :D If i get you right i don't need other techniques like acetone wash, A/B extractions etc. ? I only need to master the cold waterthing?

The same happened to me. If you get brown goo after some point, you need to smear this in acetone. I use my kitchen sc*****r and an dental pick for that. The acetone will make the goo hard and crystal looking again almost instant. Crush the solid block while in inside acetone to get everything...

I will try the could water way next time. Thanks :) I'noticed something. I don't aktually need to wait for full crystallisation. You can start scraping as soon the ethanol is evaporated. I use 55 °C for this. At first it will be all like goo but it will start to build crystals and powder in no...

Okay, i did now a lot of expirements and can say if you heat your cocain over 70 °C you will break it. But if you stay below 60 °C you can speed drying speeds alot up. Eg. i can do an aceton wash with in minutes. The result will be confortamble to consume. The important part, is that you need to...

Hi chem experts, after washing cocain with 96.5% (190) ethanol i speed up the drying process via heated plate(3D printer bed) and a normal houshold fan. Normally the tutorials recomend 24-48h drying process but with 50-60 °C heat it is a matter of few hours. Do i degenerate my cocaine with that...
