    Solubility experiments

    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...

    MDMA.HCl solubility in acetone

    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...

    Solvents recovery

    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...
