摘要: 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.

摘要: A 2,3-dihalopropanol is made by reacting 2,3-dihalopropanal with a hydrogenating agent in the presence of a transition metal-containing catalyst, under conditions such that 2,3-dihalopropanol is formed. The reaction is particularly useful as Step (3) in a process to make epihalohydrin by: (1) reacting a 3-carbon hydrocarbon with an oxidizing agent to form acrolein; (2) reacting acrolein with a molecular halogen to form 2,3-dihalopropanal; (3) reducing 2,3-dihalopropanal to form 2,3-dihalopropanol; and (4) cyclizing 2,3-dihalopropanol to make epihalohydrin. The process produces epihalohydrin using only about one mole of halogen per mole of epihalohydrin. It also uses substantially less water than existing processes.
