Extractive adsorption of 1,3-propanediol (PDO) on a novel macroporous resin enclosing medium and long-chain alcohols

Extractive adsorption is an integrated separation method employing a novel resin with both particle and liquid characteristics in terms of adsorption and extraction. In this study, Profs. Ya-Qin Sun and Zhi-Long Xiu at Dalian University of Technology designed and synthesized the novel extractive adsorption polystyrene-divinyl- benzene (PS-DVB) macroporous resin by suspension polymerization, in which n-octanol (OL-PS-DVB) or mixed alcohols of n-octanol, undecyl alcohol, and tetradecyl alcohol (MA-PS-DVB) were added as porogen and enclosed in the resin skeleton after the reaction.
