摘要/Abstract

摘要： In this paper, the aqueous two-phase systems (ATPS) containing n-ethylpyridinium tetrafluoroborate ([EPy]BF₄), sodium-based salts, and water were studied and the extraction efficiency of 2-chlorophenol was measured to study the ATPS performance in extracting phenolic compounds. The binodal curves of [EPy]BF₄ + sodium carbonate (Na₂CO₃) ATPS and [EPy]BF₄ + sodium dihydrogen phosphate (NaH₂PO₄) ATPS have been determined at 308.15 K, 318.15 K, and 328.15 K and atmospheric pressure. After getting good correlation with Merchuk equation, the binodal curves together with gravimetric method were used to calculate the tie-lines data. Furthermore, the reliability of tie-lines data was verified using Othmer-Tobias and Bancroft equations. Then, the salt influence and temperature influence on the phase behavior were discussed and the results show the salt-outing ability of Na₂CO₃ is better than NaH₂PO₄. With the aim of studying the ATPS performance in extracting phenolic compounds, extraction efficiency for 2-chlorophenol at different temperatures were studied and the results show that [EPy]BF₄ + Na₂CO₃ ATPS is preferred than [EPy]BF₄ + NaH₂PO₄ ATPS in applications.
