ABSTRACT A new palladium‐based catalyst system modified with dibenzofuran (DBF) was developed for acetylene hydrochlorination. The optimal Pd‐DBF/SAC the 0.5 wt% Pd loading and 15 DBF exhibits an elevated performance of 99.9% conversion vinyl chloride selectivity more than 400 h. Characterization analysis density functional theory (DFT) simulations revealed that presence oxygen‐containing species prevents reduction loss species, inhibits carbon deposition enhances HCl adsorbability, resulting in superior catalytic activity stability
