Cover Feature: Bio-Based Phenol from Cashew Nutshells by Catalytic Hydrocardanol Trans-Alkylation Using H-ZSM-5 Zeolite (ChemSusChem 17/2025)

Abstract

The Cover Feature illustrates the production of bio-based phenol through the trans-alkylation of hydrocardanol—extracted from cashew nutshell liquid—with toluene. Phenol can be efficiently and continuously produced by using the unique microporosity and acidity of zeolite catalysts. This study demonstrates the potential to significantly contribute to carbon neutrality by synthesizing bio-based phenol from agricultural waste.
