I have a finished product made of amphetamine oil and H2SO4. It turns out yellow. Is this due to impurities in the oil or am I mis-administering the H2SO4? Can anyone provide an example for 10ml of oil? And how to add the H2SO4?
Search for "One-pot Amphetamine Synthesis" and watch the Video, especially the last minutes. I think he uses acetone+IPA in a 1:1 solution in order to get a white product
