acetone

How safe is 15-20% H2SO4 in acetone solution? Theoretically, under specific conditions, H2SO4 can acidify acetone. But how fast is this process? Is such acid form safe and stable to be used within 24-48 hours?

Under the topic of purify acetone is always brought up. For all of our interest we'd need (if not exist) a lab analysis from before and after acetone treatment to amphetamine or cocaine salt. Since it's repeatidly meantioned but never with evidence. The common idea is that: You have lets say...

Thought it would be nice to have a post about extraction/purification of basic and essential over-the-counter products for beginners that lack proper equipment. Today will be Acetone. Why Acetone? Well, sometimes it is too expensive/time consuming/hard/illegal for the beginner to get their...

Let's start a thread on how to measure solubility in general. For specific substances and solvents better start a separate thread, since most readers are probably more interested in the results than in academic discussions. Why? Knowing the solubility at various temperatures helps: determine...

Introduction Acetone is often used to 'wash' MDMA.HCl, i.e. to reduce the amount of pollution before re-crystallization. See MDMA/ecstasy purification method. It's difficult to find data on solubility, probably because of the legal status in many countries. Using this data one can make better...

Introduction In the synthesis of mephedrone (4-MMC) and other psychoactive substances at different stages (synthesis and purification) use different solvents, which are not entered into a chemical reaction. They remain in the same form as before syntheses. However, they are mixed with dirt, and...
