Abstract :Uptakes of benzene and 12 alkylbenzenes (from toluene to tt-pentylbenzene including xylene and trimethylbenzene isomers) by both strong acid cation (Dowex 50W-X4 and X8) and strong base anion (Dowex 1-X4 and X8) exchange resins have been studied in aqueous solutions at 25°C; their distribution constants (AT) have been determined. The relationship between the octanol-water partition coefficient (K<m) and the resin affinity for solutes has been analyzed. The K values of benzene and alkylbenzenes were larger than the K values of aliphatic hydrocarbons expected from the Kim values. While the K value was increased with the alkyl chain length, no further increase in the K value was observed for w-butylbenzene and /i-pentylbenzene.
