Abstract

The invention relates to a method for oxidation of methane to form methanol via methanol esters. The oxidation of methane is carried out with oxygen or an oxygen-containing gas in the presence of one or several salts from the group of transition metals forming a redox pair with a normal potential of > 0,6 volts as a catalyst in trifluoro acetic acid and the esters are hydrolyzed to form methanol. The method is characterized in that the oxidation is carried out in a mixture of trifluoro acetic acid and a carboxylic acid anhydride or in a mixture of trifluoro acetic acid and another non-fluorinated carboxylic acid at temperatures of more than 80 DEG C.
