The noble-metal catalytic cleavage of ether bonds in lignin to obtain aromatic chems. has achieved great success, and the development of a low-cost efficient catalyst is crucial. Herein, NixLay/CNT was designed for the hydrogenolysis of benzyl Ph ether (BPE), di-Ph ether (DPE) and 2-phenethyl Ph ether (PPE) under a relatively mild condition. Owing to the synergistic effect of Ni with La, the Ni-La catalyst was especially active. Moreover, not only could the Ni-La catalyst fracture the C-O bond, but it could also transform aromatic rings to produce cycloalkanes. Physicochem. characterizations were carried out by means of XRD, TEM, H2-TPR, NH3-TPD, pyridine-IR and XPS analyses. Based on the optimal reaction condition (240°C, 4 h, 2.0 MPa H2), various model compounds could also be effectively hydrotreated to produce corresponding products. A mechanistic study revealed that cyclohexanol and methylcyclohexane were major products for the transfer cleavage of BPE. Furthermore, it has been illustrated that aryl groups played a significant role in the hydrogenation of phenol from the competitive catalytic hydrogenation reaction of phenol. This study opened up the possibility of the valorization of lignin using a rare earth metal as the co-catalyst for the selective cleavage of lignin model compounds to value-added chems. This study involved multiple reactions and reactants, such as 4-Benzyloxyphenol (cas: 103-16-2Application of 103-16-2).
4-Benzyloxyphenol (cas: 103-16-2) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Application of 103-16-2
