摘要:We Describe An Efficient System For The Direct Partial Oxidation Of Methane,Ethane,And Propane Using Iodate Salts With Catalytic Amounts Of Chloride In Protic Solvents. In Htfa (Tfa = Trifluoroacetate),>20% Methane Conversion With >85% Selectivity For Metfa Have Been Achieved. The Addition Of Substoichiometric Amounts Of Chloride Is Essential,And For Methane The Conversion Increases From <1% In The Absence Of Chloride To >20%. The Reaction Also Proceeds In Aqueous Htfa As Well As Acetic Acid To Afford Methyl Acetate. C-13 Labeling Experiments Showed That Less Than 2% Of Methane Is Overoxidized To (Co2)-C-13 At 15% Conversion Of (Ch4)-C-13. The System Is Selective For Higher Alkanes: 30% Ethane Conversion With 98% Selectivity For Ettfa And 19% Propane Conversion That Is Selective For Mixtures Of The Mono-And Difunctionalized Tfa Esters. Studies Of Methane Conversion Using A Series Of Iodine-Based Reagents [i-2,Icl,Ic3,I(Tfa)(3),I2O4,I2O5,(Io2)(2)S2O7,(Io)(2)So4] Indicated That The Chloride Enhancement Is Not Limited To Iodate.
