n-Pentanol (88 g) and 6.82 g of zinc chloride were heated to 100° C. while stirring, followed by the dropwise addition of 138.8 g of epichlorohydrin over 1 hour. The reaction mixture was heated to 115° C. and reacted for 5 hours. After completion of the reaction, the reaction mixture was cooled to 50° C. While maintaining the temperature at 50° C., 92 g of a 48% aqueous solution of sodium hydroxide was added dropwise over 1 hour. After stirring for 3 hours, 150 mL of water was added to the reaction mixture to cause separation. The water layer thus formed was then removed and the residue was washed twice with 100 mL of water, whereby 163 g of crude pentyl glycidyl ether was obtained.
