摘      要：The aim of this work was to separate 1,3-PDO from a synthetic mixture using polymeric resins,Amberlite XAD-7 and XAD-16 *** equilibrium adsorption of 1,3-PDO onto two polymeric resins were investigated in binary and tertiary *** results of binary component adsorption equilibrium indicated that the adsorption capacity(q)of 1,3-PDO at 160 g/L onto XAD-7 and XAD-16 was 835.96 and 584.61 mg 1,3-PDO/g dry resin,*** adsorption isotherms were closely predicted by the Langmuir-Freundlich model among the two isotherm model *** value of n of 1,3-PDO adsorbed on XAD-7 are much higher than those on *** result suggested that XAD-7 resin has a higher affinity for the 1,3-PDO adsorption than XAD-16 ***,the value of adsorption capacity of 1,3-PDO in the binary and tertiary component were compared at the same *** the tertiary system,although the selectivity of 1,3-PDO from XAD-7 was approximately six times higher than XAD-16,the adsorption capacity of 1,3-PDO at 160 g/L onto XAD-16 was higher than ***,the reusability of XAD-7 and XAD-16 resins in the three cycle times shows a slight loss of adsorption ***,the investigation about desorption by an ethanol/water mixture at 50%(V/V)indicated that the desorption yield of 1,3-PDO from XAD-7 was lower than XAD-16 resin for both the binary and tertiary *** was due to the more favorable adsorption characteristics of XAD-7 resin than XAD-16 resin.
