A set of supported transition metal phosphide catalysts including FeP/Si0₂, N i₂P/Si0₂, CoP/Si0₂, WP/Si0₂and MoP/Si0₂were synthesized and tested for demethoxylation of 2-methoxy-4-propylphenol in benzene solvent. The reactions were carried out in the fixed-bed reactor at 350°C and 90 bar H₂. The experimental procedure is similar to the process of demethoxylation and transalkylation using fixed bed reactor involving the Au/Ti0₂and HZSM-5. Among the tested catalysts, MoP/Si0₂is the most active catalyst for demethoxylation, delivering about 90% yield of propylphenol and 10% methylated propylphenol at 100% conversion (Figure 14e). Notably, only a small amount of toluene was produced by benzene methylation. The Ni₂P/Si0₂also showed high activity towards deoxygenation and ring hydrogenation. The main products are propylcyclohexane and propylbenzene (Figure 14b). In this case, the benzene-derived product is mainly cyclohexane (Figure 15b).
