Abstract

A process for making 2,3-dihalopropanol including reacting 2,3-dihalopropanal with a hydrogenating agent in the presence of an iridium and a second transition metal mixed metal catalyst where the second transition metal is selected from the group comprising ruthenium, iron, molybdenum, tungsten, rhenium, osmium, manganese or vanadium, under conditions such that 2,3-dihalopropanol is formed. The 2,3-dihalopropanol is particularly useful in a process for making epihalohydrin.
