Abstract
2-Amino-1-cyclopentene-1-dithiocarboxylic acid silica gel (ACDA-SG) lo aded with Ag(I) or Pd(II) ions has been examined for the group fractio nation of polycyclic aromatic sulfur heterocycles (PASH) from polycycl ic aromatic hydrocarbons (PAH) via ligand-exchange chromatography in t he normal phase mode. It is shown that metal loading has a great impac t on the selectivity of ACDA-SG for PASH and PAH. Pd(II) loaded ACDA-S G proved to be suitable for the group isolation of PASH from the aroma tic fractions of petroleum mixtures (number of condensed rings less th an or equal to 3).
