    摘要: The invention relates to a process for selectively producing alkyl halides from alkanes, such as methane and ethane at relatively mild temperatures and pressures in an organic liquid phase in the presence of halogen and transition metal complex. The alkane may be neat if in a liquid form, or may be solubilized with a suitable organic solvent, if the alkane not a liquid at reaction conditions. The reaction is for a time, under conditions of temperature and pressure and in effective amounts that will permit the formation of alkyl halides. Optional hydrolysis to the corresponding alcohols may follow. The alkyl halides have utility as precursors for alternative fuels, such as methanol.
