实验步骤: In an autoclave, 249 of the resulting dodecyl glycidyl ether, 97.2 g of water and 34.8 g of sodium bicarbonate were charged and were stirred at 200° C. for 8 hours. After completion of the reaction, the reaction mixture was dehydrated at 120° C. under reduced pressure (6.67 kPa), followed by purification by distillation under reduced pressure (13 to 26 Pa, 160 to 170° C.), whereby 117 g of monododecyl glyceryl ether was obtained. As a result of gas chromatographic analysis (hereinafter abbreviated as “GLC”), it was found that the resulting product had a purity not less than 99% and the content of a chlorohydrin ether isomer different in alcohol added position and a 2-mole adduct of epichlorohydrin (hereinafter called “organochlorine compounds”, for simplicity) was not greater than 100 ppm. After completion of the reaction was dehydrated at 120° C. under reduced pressure (6.67 kPa) followed by purification by distillation under reduced pressure (13 to 26 Pa, 160 to 170° C.)
