Vapochromic separation of toluene and pyridine azeotropes using adaptive macrocycle co-crystals

Abstract

The separation of toluene (Tol) and pyridine (Py) azeotropes is significant in the chemical industry. Herein, we present a new method for the energy-efficient separation of Tol and Py using pillar[5]arene-based adaptive macrocycle co-crystals (MCCs) that can selectively separate Py from a Py/Tol equimolar mixture with 99.2% purity, accompanied by vapochromic behavior from white to yellow.
