Abstract
AbstractAn application of multi‐component milling is described to achieve a decolorization by dismantling the orange‐red zwitterionic cocrystal (PDA)∙(APAP) (where PDA = 2,4‐pyridinedicarboxylic acid, APAP = acetaminophen) using n,n′‐BPE (BPE = trans‐1,2‐bis(n‐pyridylethylene and for n = n′ = 3 or 4). Each of n,n′‐BPE forms a colorless hydrogen‐bonded cocrystal with PDA.
