Reaction Steps
Octanol (195 g, 1.5 mole), 1.02 g (0.005 mole) of aluminum triisopropoxide and 0.7 g (0.007 mole) of 98% sulfuric acid were heated to 90° C. while stirring under a nitrogen gas atmosphere. To the reaction mixture, 92.5 g (1.0 mole) of epichlorohydrin was then added dropwise over 1 hour, followed by stirring for 4 hours. It was found that the conversion ratio of the raw material epichlorohydrin was 100%, while the yield of the resulting halohydrin ether was 95%. To the reaction mixture, 300 mL of a 4N aqueous solution of sodium hydroxide was added and the resulting mixture was stirred at 60° C. for 6 hours. After cooling to room temperature, the water layer was removed and the residue was purified by distillation under reduced pressure, whereby 175 g of octyl glycidyl ether (1,2-epoxy-4-oxadodecane) was obtained (total yield: 95%.).
