An activated carbon supported α-molybdenum carbide catalyst (α-MoC1-x/AC) showed remarkable activity in the selective deoxygenation of guaiacol to substituted mono-phenols in low carbon number alcohol solvents. Combined selectivities of up to 85% for phenol and alkylphenols were obtained at 340 °C for α-MoC1-x/AC at 87% conversion in supercritical ethanol. The reaction occurs via consecutive demethylation followed by a dehydroxylation route instead of a direct demethoxygenation pathway.
一种活性炭负载的α-碳化钼催化剂（α-MoC1-x/AC）在低碳数醇类溶剂中将愈创木酚选择性脱氧转化为取代单酚的反应中表现出显著活性。在340℃下，α-MoC1-x/AC在超临界乙醇中转化率为87%时，苯酚和烷基酚的总选择性高达85%。该反应通过连续脱甲基然后脱羟基的路线进行，而不是直接脱甲氧基途径。
