Key Points

The aim is to explore the alkylation of guaiacol with furfuryl alcohol using sulfonated PAF catalysts.
Investigated reaction conditions including temperature, reactant ratio, catalyst loading, and reaction time.
Utilized sulfonated porous aromatic frameworks as catalysts for the reactions.
Optimized conditions identified as 80°C with specific molar ratios of reactants.
Achieved ~92% total selectivity toward C-furfurylguaiacols and difurfurylguaiacols after 30 minutes.
Attained 100% conversion of furfuryl alcohol under optimal conditions.

Abstract

This study investigates the alkylation of guaiacol with furfuryl alcohol over sulfonated porous aromatic framework (PAF) catalysts, such as PAF-30-SO3H (sulfur content: 3–7 wt %). The results reveal major reaction trends, including the effects of temperature, reactant ratio, catalyst loading, and reaction time on product distribution. Under optimal conditions (80°C, guaiacol : furfuryl alcohol : H+ molar ratio = 20 : 1 : 0.05), the total selectivity toward C-furfurylguaiacols and difurfurylguaiacols reaches ~92% after 30 minutes, with 100% conversion of furfuryl alcohol.
