Selective catalytic hydrotreatment of lignin-derived phenols and dimeric ethers into alkanes is crucial for utilization of lignin and its fragments. Herein, we developed an efficient catalytic system with well-dispersed metal nanoparticles supported on SBA-15 synergistic with an ionic liquid The catalytic system could catalyze the hydrodeoxygenation (HDO) of various monomeric and dimeric lignin-derived phenols into the corresponding alkanes under acid free conditions. The synergistic [Bmim]PF6-Ru/SBA-15 (1-butyl-3-methylimidazolium hexafluorophosphate) catalysis exhibited the best HDO activity for lignin-derived phenols and dimeric ethers with >99.0% conversion and maximum >98.0% selectivity of the corresponding alkanes. The yield of cyclohexane from di-Ph ether was 97.7% with 100% conversion under 2 MPa H2 at 130 °C for 6 h. The mechanism investigation confirmed that the Ru/SBA-15 catalyst and the anion of [Bmim]PF6 played crucial roles in the hydrogenation process and deoxidization process, resp. The catalytic system was reused six times for HDO of di-Ph ether to test its stability. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Safety of 4-Benzyloxyphenol).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Safety of 4-Benzyloxyphenol
