Overview

Catalytic investigation demonstrates 72% selectivity for cyclopentyl ethyl ether synthesis using ZSM-5 zeolites, highlighting a greener route to bio-based industrial solvents.

Key Points

To evaluate the feasibility and performance of zeolite catalysts for the gas-phase synthesis of cyclopentyl ethyl ether from bio-based alcohol feedstocks.
Screened five commercially available zeolites (FER, MOR, BEA, Y, and ZSM-5) for the gas-phase etherification of cyclopentanol mixed with ethanol.
Assessed the effects of reaction temperature, zeolite silicon-to-aluminum (Si/Al) ratio, catalyst stability, and calcination-based recyclability using ZSM-5.
Medium-pore ZSM-5 delivered the highest performance, achieving 72% selectivity toward cyclopentyl ethyl ether at approximately 90% cyclopentanol conversion.
Elevated reaction temperatures and higher concentrations of zeolite acid sites shifted reactivity toward cyclopentanol dehydration into cyclopentene rather than etherification.
The ZSM-5 catalyst showed high operational stability and retained activity upon regeneration through calcination.
