【Abstract】 N,N-diethylamineethyl benzyl ether was synthesized in good yield(80%) from the Williamson reaction of diethylamineethnol with benzyl chloride by using sodium hy- droxide as base and benzene as solvent.The paper also discussed the factors that affect the etherification yield of the products such as catalyst,solvent,reaction temperature,reaction time and reactant moder ratios and the best reaction conditions were determined.The result of b.p determination,IR and ~1H-NMR spectrometry indicated that synthesized product was N,N-diethylamineethyl benzyl ether.更多还原
