Activation, oxidation, and functionalization are the essential steps in the direct selective conversion of methane into liquid chemicals such as methanol, formaldehyde, higher paraffins, and olefins. In the best process so far for the synthesis of methanol from methane, the reagent is converted with 90% conversion and 81% selectivity into methyl bisulfate in 102% sulfuric acid at 220°C and in the presence of Pt complexes that contain very stable ligands. The desired product can be trapped by esterification and thus be protected from nonselective consecutive reactions.
活化、氧化和官能团化是将甲烷直接选择性转化为液态化学品（如甲醇、甲醛、高级链烷烃和烯烃）的关键步骤。在目前由甲烷合成甲醇的最佳工艺中，试剂在220°C、102%硫酸中，在含有非常稳定配体的铂配合物存在下，以90%的转化率和81%的选择性转化为硫酸氢甲酯。所需产物可通过酯化反应捕获，从而避免非选择性连续反应。
