I am also thinking about whether I bought fake raw materials, I bought CAS 705-60-2

I don't know how to use it, I took about 0.5g, snorted a little, it didn't work at all.

No idea what went wrong, no testing equipment. The resulting amphetamine phosphate has no effect at all.

Ask you, amphetamine phosphate, how should I take it? What is the most convenient way to use it?

Only 60% sulfuric acid can be purchased, can it be used for crystallization?

So amphetamine can never be made into such crystals.

Can amphetamine be made into crystals like this?

I don't evaporate the solvent IPA, I add phosphoric acid directly to the mixture of IPA and amphetamine! Can this be crystallized? Let me try it again myself, practice will bring true knowledge

Thanks for your reply, acetone is strictly regulated in my country and is not available at all.

Add cooling oil to the outer layer to cool down, or heat oil to heat up

This kind of reactor is very suitable for this reaction

I cooled the solvent to 3 degrees in an ice-water bath, then added NaBH4, magnetically stirred with the rotor, creating a downward vortex. NaBH4 precipitates and precipitates at the bottom under stirring at low temperature, and does not react with water in the solvent at low temperature. Do not...

I can't buy anhydrous acetone, can I use other solvents as crystallization solvents? What are the alternative solvents?

Excuse me, does the crystallization process need to evaporate the IPA solvent to obtain pure amphetamine oil, then use anhydrous acetone as a solvent and add phosphoric acid to form a salt?

I found that magnetic stirring NaBH4 will precipitate, can't add NaBH4 with magnetic stirring nor freezing solven
