Hello, I would like to ask about the proportions of Pseudo E / iodine / red phosphorus when synthesizing, say, 7.5g or 15g of pseudoephedrine. In some threads, the proportions are given as 1/1/ ⅓ (pseudo E / iodine / phosphorus), but I have also come across proportions of 1/2/1, etc. Could someone advise what proportions to stick to during the first synthesis? and what to pay special attention to? Thank you for any advice. Best regards
