    摘要: A process for the production of detergent range alcohols and ketones by reacting an alkane with a hydroperoxide in the presence of a transition metal porphyrin catalyst is described. Preferred hydroperoxides include cumene hydroperoxide and tertiary butyl hydroperoxide. The transition metal porphyrin catalyst may be transition metal phthalocyanines, transition metalloporphines and the like. The transition metal itself may be iron, manganese, cobalt and mixtures thereof. Suitable ligands include, but are not limited to imidazoles and lithium borate. Other useful additives include alkali metal perchlorates, such as sodium perchlorate, iodosylbenzene and alkali metal superoxides, such as potassium superoxide, and phase transfer catalysts such as tetrabutyl ammonium bromide.
