Dichloromethane oxidation
WebDichloromethane (DCM or methylene chloride, methylene bichloride) is an organochlorine compound with the formula C H 2 Cl 2. This colorless, volatile liquid with a chloroform-like, sweet odour is widely used as a solvent. Although it is not miscible with water, it is slightly polar, and miscible with many organic solvents. WebAbstract The reaction mechanism of dichloromethane (CH 2 Cl 2) oxidation on LaMnO 3 catalyst was investigated using density functional theory calculations. The results showed that CH 2 Cl 2 dechlorination proceeds via CH 2 Cl 2 → CH 2 ClO → HCHO.

The reaction mechanism proceeds via an ene reaction with chromyl chloride, forming the precipitated Étard complex. The Étard complex is then decomposed by a [2,3] sigmatropic rearrangement under reducing conditions to prevent further oxidation to a carboxylic acid. Reducing conditions for the decomposition of the Étard complex are provided by saturated aqueous sodium sulphite. Typical sol… WebAu, Pt, and Pt-Au catalysts supported on Al 2 O 3 and CeO 2-Al 2 O 3 were studied in the oxidation of dichloromethane (DCM, CH 2 Cl 2).High DCM oxidation activities and HCl selectivities were seen with all the catalysts. With the addition of Au, remarkably lower light-off temperatures were observed as they were reduced by 70 and 85 degrees with the Al …
