| 초록 | The efficient separation of ring-containing compounds (e. g., cyclic ethers and cyclic alcohols) from aqueous solutions is important in the chemical industry, where many solvents have been tested to improve such recovery. Tetrahydrofuran (THF) is an organic solvent, an important organic raw material, and the precursor of polymers. Due to its proton-accepting nature, it is used as a solvent in many chemical industries. Many chemical and pharmaceutical industries encounter problem in separating THF from aqueous waste streams since their mixture form azeotropes at low compositions of water. The purpose of this work is to determine liquid-liquid equilibrium (LLE) data of water + THF + solvent (n-heptane, butyl acetate, isopropyl acetate, isoamyl alcohol) at 25 ℃ and atmospheric pressure. The selection of the optimum solvent to separation THF from aqueous solution was investigated. In addition, the LLE data have been predicted with the UNIFAC method, and they are compared with the experimental data at 25 ℃. |
