"6:18-7:23 - Decantation. Collect the top layer with amphetamine base in alcohol. It can be dried by a small amount of anhydrous magnesium sulfate. The slag can be extracted with a non-polar solvent (ether, benzene, toluene), then a solvent is evaporated." Can I evaporate the solvent slowly...

Did you get something out after vacuum Destillation?

I think I extracted it, at least I did everything right. After filtering out the amalgam and hydroxide, I added a few HCl acid to rm until it was pH 3 and extracted it with ether 3 times. Then I alkalized it with NaOH to PH 12 and extracted again 3 times. How do you mean? After reducing the...

No I generated HCl from NaCl and H2SO4 but I didn't dried it and bubbled it straight to the ether extract. A little bit of HCl definitely dissolved into the ether because it releases HCl Vapour.

I had the freebase dissolved in the ether and bubbled HCl Gas into it without reducing the volume. So i guess it's now the HCl salt somehow dissolved in the ether but I don't really know. I try now to reduce the volume but slowly under cooling because I fear that the HCl produced in the ether...

I tried the synthesis with 10g and everything looked very good, I even think I smelled methamphetamine while I filtrated the RM. Stupidly, I forgot to concentrate and dry the extractions in the last step and bubbled HCl straight in. The petroleum ether became cloudy at first and when I...

I ordered 250g Ma Huang and tested the simple extraction with 25g. I powdered it in the blender and extracted 1 part with ethanol and 1 part with IPA, dried both extracts at around 30°C and as expected, both extracts were green from chlorophyll and after concentrating and freezing nothing...
