摘要

Thirteen isomers of branched para-nonylphenols (para-NP) in three technical mixtures were isomer-specifically determined using their synthesized standards by SIM of structurally specific ions, m/z 135, 149 or 163 with GC–MS. Of the 13 isomers, four isomers, 4-(2, 4- dimethylheptan-4-yl) phenol, 4-(4-methyloctan-4-yl) phenol, 4-(3-ethyl-2-methylhexan-2-yl) phenol (3E22NP) and 4-(2, 3-dimethylheptan-2-yl) phenol synthesized for their ...
