The Williamson ether synthesis has been applied to the preparation of polyoxyethyleneglycol mono- and di-ethers. These were obtained by reacting the mixed potassium salts of hexaoxyethyleneglycol with alkyl or aryl halides. Hexaoxyethyleneglycol monoethers of the type R•O(CH2CH2•O)6H, (R = n-C10H21, n-C12H25, n-C14H29, and p-iso-C8•H17•C6H4•O•CH2CH2) and diethers of the type R•O(CH2•CH2•O)6•R, (R = n-C10H21
Williamson 醚合成已应用于制备聚氧乙烯乙二醇单醚和二醚。这些是通过将六氧乙二醇的混合钾盐与烷基或芳基卤化物反应而获得的。R•O(CH2CH2•O)6H 型六氧乙二醇单醚(R = n-C10H21、n-C12H25、n-C14H29 和 p-iso-C8•H17•C6H4•O•CH2CH2)和二醚R•O(CH2•CH2•O)6•R, (R = n-C10H21、n-C12H25 和 n-C14H29) 已制备成纯态,并确定了它们的一些性质。
