Hello and an MDPV Question

Crack cocaine is not the bloody free base.

FREE BASE. WHAT IS THE PROBLEM OF UNDERSTANDING THE TERM FREE?

Are you a crackhead? :|

crack cocaine = cocain hydrogencarbonate + left over nacl

you even concede yourself to don t know anything about chemistry.
then don t trying to explain it to me.
stim users tolerance with wrong posts is always low =D

Well.... clearly, since you understand it, I'm not trying to explain anything to you. I'm trying to answer people's questions and provide information without stepping over the "no synthesis" line. You clearly don't don't have any questions, so I'm not trying to answer them.

I do in fact understand that the greenish-yellow oil is in fact the freebase form of mdpv, and have said so. Many times in this thread. I just don't have any interest in mdpv. I think it's a sucky substance. I do have an interest in whatever it is turning into - which is unquestionably not mdpv.

And yes, I'm not a chemist. I'm a "Tan mdpv" devotee. Nothing more. But if you have helpful suggestions for cleaning up this process, or can provide evidence, for example, for why bacteria could play no role in converting a warm, soupy dish of hydrogen, oxygen, carbon and sodium into some thing else, then I would like to hear it.
 
i appreciate your efforts, I see the difference of your process now :3
excuse me acting rude, gonna investigate it.
 
Perhaps you could send it to the ecstasydata labs in holland. They will run a GCMS to help you identify it, but it's not cheap so would be worth checking that you are allowed copies of the results.

I had already thought of that. problem is: They run a standard set of tests for known recreational drugs. I feel certain that this chemical will be flagged as mdpv, much like mdppp is flagged as being mdpv by standard tests. They are radically different substances yet test the same.

What I need is a more thorough analysis to get the full chemical structure. I don't trust large labs (for obvious reasons). I was hoping to find a chemical wizard who could become a compadre in this mystery.

I'm sure that there would be someone out there interested enough with access to GCMS etc that could test it for you. Just gotta hope they see the thread!

Something just popped to mind then; although unlikely, this "mystery-pseudo-mdpv" could fall outside the cathinone ban!
 
I have a lot of experiences to change MDPV HCl salt to Freebase, with several methods.
At now the highest yield and easiest method is below;

a) Prepare something basic and hydrophilic substance, which pH must be higher than 12 (the higher pH the higher yield freebase due to existence the chemical equilibrium between MDPV-HCl, in other words ionised tertiary amine, hydrophilic style of MDPV, and MDPV freebase, in other words deionised lipophilic style of MDPV, and this balance depends on pH of aqueous layer.), for example, ammonia water NH4OH or if you could gain Sodium hydroxide solution, and non-polar solvent like hexane (Ether or methylene chloride is slightly polar and this polarity never be negligible in this case.) or pentane.

b) Put adequate amount of MDPV-HCl in a flask or a testing tube, and then pour basic aqueous liquid that is prepared. Never use hot water over 40 degree celsius because MDPV freebase is unstable, especially in the high temperature. You can confirm the changing at this time for colour turns while to yellow. MDPV freebase is white (not tan) in solid style though yellow in liquid style.

c) Pour adequate amount of non-polar solvent, and shake it. MDPV freebase is moving to non-polar layer, so this layer shows yellow, and disappears the yellow-colour substance from aqueous layer. MDPV freebase immediately decomposes in aqueous layer so hurry up. If residue substance exists in aqueous layer you have to pour non-polar solvent more amount, and do it again. At this time it must be two separated layer exist in a flask, upper is yellow organic layer and bottom is aqueous layer, this is ammonium chloride solution if you succeeded.

d) Put Non-polar layer on a dish or something, and throw aqueous layer away.

e) Wait till solvent completely volatilised. Never use heat for volatilisation, if you did MDPV would be decomposed easily and you would gain nothing. It's better to conserve lower than 10 degree Celsius temperature the environment around this step, then MDPV freebase easily appears in solid style.

f) MDPV freebase is solid at 40 degree celsius in fact, but this point it may be in oily liquid with yellow colour, then cooling the dish whole.

g) After about 12 hours MDPV freebase has turned to solid. It's white if not decomposed, so the solid is coloured at this point, you should do again with attention to temperature.

P.S.
MDPV HCl is harmful to smoke because it's close to the vaporise point and decompose point and decomposed substance is strong adrenergic toxicity. MDPV freebase, if you made properly, is almost no harm at all to smoke, but again, never forget to attention to decompose when smoked.
 
Some additional comment:
Baking soda, chemically Sodium Bicarbonate NaHCO3, indeed indicate alkali in solution, however this is too weak to turn MDPV-HCl to MDPV freebase. If you heat the solution then little amount of MDPV freebase may yield, but this has already decomposed due to heat and smoking this substance is very dangerous to your cardiac system.

Absolutely correct. If it's the pure mdpv oil you're after, these steps are extremely important and I urge you to adhere to them strictly. MDPV does indeed decompose in water, over time, and with heat.

I, however, don't particularly like mdpv, and simply let it decompose. So..... I liberally use water, I don't hurry up (I wait up to a week), and I do use heat (but not too much, else you won't like the decomposition overmuch).

While I agreed fully with your previous post, I have to disagree with this. If you use only NaHCO3 at room temperature, and gently agitate the solution, it will indeed freebase mdpv. Here's a photo of the oil collected from a room temperature freebase:

The precipitate at the bottom is due to drawing it up into the hypodermic needle along with the oil (unintentional) when I extract the oil.

You may notice that it has already started to to darken from decay due to contact with the water and air during the freebasing. I will now slowly heat it to hasten its decay.
 
how about heating the sodium bicarb in water to produce sodium carbonate (a stronger base) if one is needed.
 
In fact, MDPV-HCl turns MDPV freebase in saturated solution of NaHCO3 certainly, but its pH is about 8.4, this is very close to MDPV itself in the aspect how basic it is, so you cannot adequately extract from aqueous layer to organic layer. Aqueous layer in your photo may quite much MDPV-HCl exist, so this method yields very low. In short, it's not impossible but very inefficient and wasteful. And because of your notice of decay in water I recommend to use the substance most basic you can gain legally and to move organic layer rapidly.
 
Sodium Bicarbonate turns into Sodium Carbonate, which is relatively strong base, at about 70 degree celsius. So it's one of the right way to boil NaHCO3 solution, then cool down this to 10 degree celsius and then pour MDPV-HCl in it.

P.S.
I do not recommend to this method because NaHCO3 is relatively less soluble to Na2CO3 so if you use this you have to boil saturated NaHCO3 solution and when turn into Na2CO3 add NaHCO3 again, unless you could gain adequate amount of Na2CO3 solution.

Keep on posting guys, although I'm having a hard time understanding anything I still find this thread extremely interesting! If only meth cooking had been a part of my chemistry school curriculum.
 
Anyone who don't have sufficient level of chemistry and biology knowledge should not use any substances. It's responsible to have adequate science level at least for understanding my posting, unless bring incidents and it must be controlled, and this is huge crisis against science.

This is more than slightly unrealistic.
 
It's certainly unrealistic to demand full knowledge to all RC users but it's ideal.

Is it ideal, then, that to enjoy the finest of cuisine, one must be a Michelin starred chef?

Or to make toast, or just a sandwich, one must be confident baking bread?

I have a lot of knowledge on how drugs and the human body interact, definately not enough to mess around with the chemicals, changing their nature like you're doing.
