WebAu, Pt, and Pt-Au catalysts supported on Al2O3 and CeO2-Al2O3 were studied in the oxidation of dichloromethane (DCM, CH2Cl2). 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 … WebApr 24, 2008 · Just one note of caution, given that you are using dichloromethane in systems with reverse phase solvents. Ensure that you thoroughly flush the system with miscible solvent, as any residual methylene chloride can slowly hydrolyse when water is present, forming HCl, which is corrosive to most stainless alloys.
