Abstract
The separation of para-halotoluene (PHT) is crucial in the chemical industry. However, due to the similar physical properties of those halotoluene isomers, industrial separation can be time-consuming and energy-intensive. Herein, we present an energy-efficient method for adsorptive separation of PHT, such as para-chlorotoluene and para-bromotoluene, from their trinary isomer mixture using a trianglimine (TI) macrocycle. The selectivity of the separation is dominated by the C-H···π, ···π, and C-H···Cl interactions between the TI macrocycle and captured guest molecule. Moreover, the macrocycle of the molecular sieve exhibits a high degree of recyclability, as it can maintain the performance over multiple cycles. These findings reinforce the viability of using molecular sieves for sustainable chemical separation processes.
