The present invention relates to an atom economic procedure of preparing iodoalkanes by hydroiodination of alkenes. In particular the present method features the generation of anhydrous hydrogen iodide from atomic hydrogen and iodine in situ by using transition metal precursor and phosphine ligandcatalyst.

A process for producing acetic acid while efficiently separating permanganate reducing compounds (PRC's) and methyl iodide is provided.

PRC's are separated or removed from a mixed composition (3A) containing PRC's and methyl iodide by distilling the mixed composition in a distillation step (5) to form an overhead stream (5A), a side-cut stream (5B), and a lower stream (5C). In a distillation column of the distillation step (5), an extractant (e.g., water) extracting PRC's preferentially to methyl iodide is added to a concentration zone in which PRC's and methyl iodide are concentrated, and an extraction mixture falling from the concentration zone is withdrawn as the side-cut stream (5B).
