What is a/b purification, can you explain me how to do it? I'm a beginner

hello

I have something to ask and ask for help.

I'm doing Synthesis MDMA.

What is a/b purification, can you explain me how to do it? I'm a beginner

Thank you very much for the answer.

A/B purification is not a thing. A/B EXTRACTION is a thing. Use The Search Engine. It is very difficult to do something you don't understand. Can you synthesize MDMA if you don't even know the mechanisms? You don't even know THE NAMES of them? I'm skeptical.
