Separation of Cyclohexanol from Cyclohexanol/Cyclohexene Mixtures by Crystals of Pillar[6]arene Containing Three Benzoquinone Units
Abstract
Here, we develop a new absorbent for efficient separation of cyclohexanol (CHA-ol) and cyclohexene (CHA-ene) by using crystals of pillar[6]arene with three benzoquinone units (P3QA). P3QA crystals are found to show remarkable selectivity for CHA-ol in 50:50 (v/v) CHA-ol:CHA-ene mixtures with a purity of 95.2%, along with vapochromic behavior.
