Cleaning of α-PVP/methamphetamine, etc.
α-PVP is easy to synthesize, so it is mostly of high purity. We will clean 1 gram available to each buyer. The consumer will notice how much softer, cleaner and tastier the substance is. Even if α-PVP shines and smells nothing, having spent a little experience, the difference will be noticeable.
The method is resorted to by those wishing to obtain the fastest result without weight loss. We will remove everything superfluous and enjoy cleanliness, and we will leave the dirty part for a black day.
You already know an easy way to purify mephedrone, where isopropyl alcohol is used as an extractant. In today's purification example, we use anhydrous acetone. In acetone, the solubility of α-PVP is less than in alcohols.
Without of acetone, use methanol from alcohols - these recommendations concern α-PVP/methamphetamine/MDMA to a greater extent than mephedrone or amphetamine. Any salts (sulfate, phosphate, hydrochloride, etc.) of mephedrone, amphetamine, 4-FA, etc. are not soluble in acetone, methanol and isopropyl alcohols.
The solubility rate of the drug is affected by the temperature of the extractant. The colder the extractant, the slower the drug will dissolve in it. Therefore, an extractant kept in the freezer is always used.
Dishes in the form of a piala, a cup or a Petri cup will be suitable as a washing container. It is convenient to drain the extractant with impurities from such containers, leaving washed powder.
To clean α-PVP, wash the powder with acetone (previously cooled in the freezer). To accomplish this, add an equal weight part of acetone (1:1) to one part of α-PVP. Or twice as much. Actively mix the extractant for a few seconds and let the powder settle on the bottom of the container. In addition to impurities, acetone partially takes the product itself, so it should be washed quickly. There are a couple of minutes for the whole process.
Use a syringe to take acetone, leaving α-PVP in the initial container. Then evaporate acetone in a Petri dish (crystallization can be accelerated by stirring). As a result, the product is divided into two parts - clean and dirtier, without weight losses. The dirty part is in a portion with acetone, and the clean part is in the original container. Both parts should be dried to a constant weight before use.
The purity of α-PVP can be determined using knowledge from this topic. But the most affordable assessment of purity is the smell of powder, the taste of smoke, as well as the type of substance and smoking device. In the vast majority of cases, the products contain traces of precursors not only due to violations of the synthesis technology, but also insufficient purification/drying (reference to the topic of drying, in the process). The final purification step in synthesis is mandatory. It depends on the load on the consumer's body, the purity of the effects, shelf life, product presentation. On the chemical side, α-PVP can be clean, but after an hour of smoking, the deposit on the glass remains, which must be cleaned regularly. The composition of the carbon deposit is reliably unknown. Therefore, it should be borne in mind that in the synthesis process no harmless precursors are used and in addition to their residues in the drug, a significant amount of combustion products remains on the glass. When the glass is calcined, the deposit has a bromine-like smell, and this is not surprising because the intermediate compound of 2-Bromo-1-Phenylpentan-1-One synthesis is obtained by bromination.

By the way, precisely by the type and number of impurities in the sample, analysts determine not only the professional level of the laboratory and the method of production, but also whether the goods are imported and approximate volumes of synthesis. And if foreign particles (hair, etc.) are detected, you can determine the DNA of the participant in the production/sale, and then enter it in the database.

Original # 1 = 1g; Dirty # 2 = 0.565g; Clean # 3 = 0.435g;
In the photo on the right, α-PVP after cleaning. Washed with cooled acetone and dried to a constant weight. The sample smells nothing; when steaming, the taste is significantly lower than it was before cleaning. Note the slight presence of external differences between the starting (sample was already pure) and the purified powder.
