Aerobic oxidation of alcs. is one of the most important methods for the production of aldehydes. In this work, a scalable, continuous flow synthesis method for the aerobic oxidation of alcs. using a copper catalyst with redox-active ligand and mol. oxygen (O2, air) was developed. The yield of benzaldehyde could reach 93.4% by optimizing the following conditions, such as copper content, solvent, O2 flow rate, and temperature This synthesis method exhibited excellent functional group compatibility for various alcs. with excellent reactivity and reusability, avoiding the use of some nitroxyl radicals (TEMPO, ABNO) or base additives. In the microchannel reactor, the total reaction time could be reduced from 24 h to 40 min, and a simplified kinetic model was established. In the experiment, the researchers used many compounds, for example, (4-Methoxyphenyl)methanol (cas: 105-13-5SDS of cas: 105-13-5).
(4-Methoxyphenyl)methanol (cas: 105-13-5) belongs to ethers. Ethers are good solvents partly because they are not very reactive. Most ethers can be cleaved, however, by hydrobromic acid (HBr) to give alkyl bromides or by hydroiodic acid (HI) to give alkyl iodides. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.SDS of cas: 105-13-5
