Substance is Alpha-PiHP (Alpha-Pyrrolidinoisohexanophenone). Melting point according to caymam etc is 78 degrees celsius. Mine is 82 celsius. High purity in othert words. If it gets burnt, then the pyrolisis most likekly starts a chemical reaction, like every pyrolisis. Is it possible to make a...

I just sent u a email. I know the prifce is listed here. But read my mail please. Our cooperation will be VERY profitable, so pleasea dont just ignore it beacuse of the low thinhs. I dont wanna say too much here.

pH was 6-7

I try ur reply first. My idea was to convert it fo freebase with NaOH and deionized water. And then add HCl 30% to make it HCl again, and then add Acetone to crash it out. Cuz I cant make HCl gas :/ Or do i need to clean the freebase before i turn it to HCl again?

Hi,(Info about the substance). Its a newly synthesised Pyrrolidino-phenone. Info about the substance: Trivial name: 3-Methyl-PVP IUPAC: 1-(-3-methylphenyl)-2-pyrrolidin-1-yl-pentan-1-one Its like alpha-pvp but with a methylgroup on the 3rd carbon position on the phenyl ring. This batch is so...

Info: IUPAC: 1-(3-methylphenyl)-2-pyrrolidin-1-ylpentan-1-one Trivial name: 3-Methyl-alpha-PVP Appearance: White, completely homogenous texture. Very mild odour. All this points to high purity. The vendor is also known to produce and synthesise very good quality products with high purity. A...

As stated, I know how to do a single solvent recrystallization. I have done over 100x of them, mainly with distilled H2O. I oversaturate the solution with the substance at around 90-96 celsius. And I then let the solution cool to RT very slowly in a water bath that is around 40c. Once it reach...

Cant I turn my PV to the free base, extract the freebase oil or extract the water and leave the freebase oil in the vessel. Wash it with suitable solvent (Maybe I can skip this? |Question: When made to the freebase oil, is it more pure than the starting HCl powder?) And then turn it to HCl...

as said.. Tapwater has minerals and will ruin the taste and vape experience. And the solubility in H2O is already very low, like 10mg/ml (25c). I've done countless of re-X with these Pyrovalerone analogues. But only with distilled H2O

Hehe, yes I know Denatonium B is the most bitterest substance. I just stated what I had. And I know a condenser isnt used in a recrystallization. But I need to distill my tapwater to do a Re-X. I did a Re-X with tapwater before, and it made it vaporize worse, it tasted worse due to the minerals...

It is soluble in acetone. But maybe some impurities isnt? Should i dissolve it in acetone and then get rid of the insolubles, and then let the acetone solution containing my substance to evaporate? Would that clean it up a little?

To above: Im sorry, i havent read yet. I wll do now, but i wanted to show pic first. Here is a picture I dont have distilled water. My condenser is cracked... And tapwater contains so much else and it makes the crystals taste like shit.. Buut... The actual coil where the vapor goes thru is not...

Hello, New member here, but been reading for atleast 5 months. I have basic chemistry knowledge and a little more. I have studied "Chemistry 1" its called in my country. Its Chemistry for highschool (Age ~15). I have also read about Organic chemistry and Pharma-chemistry for about 3 years by...
