実験手順: In a four-necked 300-ml flask, 100 g (0.69 mole) of amyl glycidyl ether obtained in Example 1, 25 g (1.39 mole) of water, 2.31 g (0.028 mole) of 48% sodium hydroxide and 5.54 g (0.028 mole) of lauric acid were charged, followed by heating to 90° C. while stirring under a nitrogen gas atmosphere. The stirring was continued for 8 hours. After excess water was distilled off, the residue was distilled under reduced pressure (100° C., 0.133 kPa), whereby 110 g (0.59 mole) of amyl glyceryl ether was obtained (yield: 86%, purity: 99%). After excess water was distilled off the residue was distilled under reduced pressure (100° C., 0.133 kPa)

実験手順: A 3-neck, 2-liter round bottomed reaction flask (equipped with overhead stirrer, cold water condenser, mercury thermometer and addition funnel) are charged with about 546 g of aqueous NaOH (about 50% concentration) and about 38.5 g of tetrabutylammonium hydrogen sulfate (PTC, phase transfer catalyst). The content of the flask is stirred to achieve dissolution and then about 200 g of 1-pentanol is added along with about 400 ml hexanes (a mixture of isomers, with about 85% n-hexane). Into the addition funnel is charged about 418 g of epichlorohydrin which is slowly added (dropwise) to the stirring reaction mix. The temperature gradually rises to about 68° C. due to the reaction exotherm. The reaction is allowed to continue for about 1 hr after complete addition of the epichlorohydrin (no additional heat). dissolution a mixture of isomers is slowly added (dropwise) to the stirring reaction mix gradually rises to about 68° C. due to the reaction exotherm no additional heat)
