Abstract
Long chain alcohols and acids or other similar oxygenates such as esters are produced from paraffins of similar carbon number by a process comprising paraffin dehydrogenation, carbonylation, and separation. Preferably a mixture of paraffins extending over several carbon numbers and recovered from a kerosene fraction is processed, and unconverted paraffins are recycled to a dehydrogenation zone. Alternative reaction zone configurations, catalyst systems and product recovery methods are disclosed.
