Abstract: A 2,3-dihalopropanol is made by reacting 2,3-dihalopropanal with molecular hydrogen in the presence of a transition metal-containing catalyst, under conditions such that 2,3-dihalopropanol is formed. The reaction is particularly useful, for example, as Step (3) in a process to make epihalohydrin which may be generally prepared 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 with molecular hydrogen 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.
