Heterogeneous Mn-Based Catalysts for the Aerobic Conversion of Methane-to-Methyl Trifluoroacetate

Methane conversion strategies that protect methanol via in situ esterification achieve higher yields compared to direct methane without product protection; however, most of these high-yield systems operate under unfavorable conditions. To date, there is very limited work developing heterogeneous catalysts for methane-to-methyl-ester conversion, and studies demonstrating the activity manganese are limited. We have prepared a series silica-, titania-, zirconia-supported measured aerobic methyl trifluoroacetate diluted acid. The silica-supported catalyst exhibits high overall activity, but significant amounts homogeneously active observed. Titania- catalyze reaction heterogeneously with activities up 613 μmol gcat–1 h–1 show nondetectable leaching. Manganese oxide poorly dispersed on titania zirconia, whereas dispersion realized silica. This demonstrates facilely synthesized supported converts satisfactory improved conditions acid, those conventional systems.
