    hi all, in fact im currently facing a situation here which im truly looking for your help.

    im having a liquid base meth which i've tried push/pull for number of times and even adding ice cube and salt which didnt seem making any effects on crystallization. have u ever face this kind of weird situation or even heard? what is the option for me in order to get the meth into crystal?

    thanks a lot.

    What? Is SWIY trying to crystalize your meth freebase? or are you trying to make your powder meth into crystals?

    if what you have really is meth freebase all you need to do is gass it with the gas of choice
    HCL or hydrogen sulfide
    that will yield powder meth

    you might have too much solvent.. you only need to use the minimum amount.. if this is the case evaporate some off and try again. if this still isn't working try scratching the bottom of the flask. for some reason this can induce a response. i don't know what your doing with an ice cube and salt...

    basically SWIY is taking your crude meth (that is meth + impurities) and trying to purify as much as possible. these are the steps involved in recrystallisation:
    1: dissolve in a hot alcohol solution to dissolve the meth.
    2: filter the hot solution to remove insoluble purities
    3: let the solution cool. this allows the meth to precipitate out (turn to solid). so here SWIY will have the solid meth in the alcohol solution which also contains impurities that are soluble in the alcohol.
    4: filter this solution to leave SWIY with pure crystal meth.

    there is a lot of opportunity to lose the product in the filter paper so make sure that the solution in step 2 is hot as it runs through the filter in to the flask.

    SWIM has always been taught that this is a recrystallisation. does the alcohol/acetone allow for polar/non-polar impurities to be removed?

    yes techniqly it is a recrystallization...but it is a single solvent recrystallization as to where the denatured alcohol and acetone one is a dual solvent thus giving you twice as pure product....
    umm if the non polar impurites arent coming out do a non polar wash with some toluene or xylene

    Help, I failed to get crystal meth

    when I bubble anhydrous HCl(dried by concentrated sulfuric acid) into
    the methamphetamine, instead of forming crystals, an oil settles to the
    bottom of the flask.

    I made methamphetamine from phenylacetone,methylamine,actived aluminum,
    all materials are analytical pure.

    My phenylacetone is pale yellow in color, has a unique smell. It is got
    by vacuum distillation, at -101KPa and 110 °C .

    The free base is distilled out under a vacuum of -96KPa and temperature
    118°C. The liquid methamphetamine is clear, colorless, has a slight amine
    smell.

    I disolve the methamphetamine in toluene, which is maybe industrial pure,
    not analytical pure. The solution is also clear and colorless. when I bubble

    anhydrous HCl(dried by concentrated sulfuric acid) into it, instead of
    forming crystals, an oil settles to the bottom of the flask.

    I drop some anhydrous calcium chlorideinto it,still no crystals form.

    I have tried the whole procedure 4 times, thr results are the same.

    Could anybody be so pleased to help me to solve the problem?

    Thanx very much.
