Abstract
Catalytic processes have been developed for direct ambient air oxidative conversion of hydrocarbons to aldehydes and unsaturated alcohols. Aliphatic hydrocarbons including methane, hexanes, octanes, decanes, gasoline, diesel fuel, oils, solvents and other organic compounds have been oxidized by this catalytic process. The catalysts are based on molecular strings of di-, tri- and/or poly-groups of transition metal complexes. Laboratory results have demonstrated [iron(II)]2, [manganese(II)]2 and related families of catalysts to be effective for ambient air direct oxidative conversion of hydrocarbons to products in high yields at room temperature and above, while [cobalt(II)]3 was effective for air oxidative conversion of methane to formaldehyde and for other gaseous hydrocarbons to their corresponding aldehydes at elevated temperatures.
