Abstract
A process for the carbonylation of saturated hydrocarbons to give an oxygenated saturated hydrocarbon is disclosed and claimed. The process involves using an acidic ionic liquid catalyst to catalyze the carbon monoxide addition to the saturated hydrocarbon at reaction conditions to form an oxygenate. The acidic ionic liquid comprises a Lewis or Bronsted acid in combination with a quaternary nitrogen-containing compound. A specific example is a mixture of aluminum chloride and n-butylpyridinium chloride.
