Separation of m-Cresol from Coal Tar Model Oil Using Propylamine-Based Ionic Liquids: Extraction and Interaction Mechanism Exploration.

ABSTRACT: m-Cresol is an important chemical material, which is mainly derived from low-temperature coal tar. In this work, for separating m-cresol from coal tar model oil, two propylamine-based ionic liquids (ILs) propylamine formate ([PA][FA]) and propylamine acetate ([PA][Ac]) were selected as extractants. The selected ILs were synthesized and characterized by Fourier transform infrared (FT-IR) and ¹H nuclear magnetic resonance (NMR) spectroscopy. The effects of temperature, mass ratio of IL to model oil, and separation time on the separation efficiency of m-cresol were explored. The separation efficiency (SE) and distribution coefficient (D) were calculated from the experimental data to assess the separation performance of [PA][FA] and [PA][Ac]. The results
