Vapor–liquid equilibria for tetrahydrofuran + ethanol

Tetrahydrofuran (THF) is an excellent organic solvent and often mixed with ethanol in the waste of pharmaceutical industry (the production of betamethasonum as an example) The system of THF (1) and ethanol (2) forms a minimum boiling point azeotrope at atmospheric pressure at x 1 ≈ 0 90 T ≈ 338 6 K [9] which leads to the unfeasibility of separating the THF + ethanol mixture by
